The three lives of Japanese military pesos

1942 Japanese Invasion Philippines Peso with a JAPWANCAP Stamp

In his reply to Mike Sproul, Kurt Schuler brings up the question of the determination of the value of a very peculiar kind of money: military currency. Curious, I investigated one example of such money, Japanese-issued "invasion money" in Philippines both during and after World War II. As best I can tell, the mechanism by which the value of these military notes has been mediated has gone through three different phases, each of them teaching us something interesting about money.

In January 3, 1942, a few weeks after successfully invading Philippines, the Japanese Commander-in-Chief announced that occupying forces would henceforth use military-issued currency as legal tender. Notes were to circulate at par with existing Philippines "Commonwealth" Pesos. Since this military scrip was not directly convertible into existing pesos, the trick to get it to circulate at par can probably be found in the tersely titled proclamation Acts punishable by death which, among seventeen acts that could result in loss of life, listed the thirteenth as:
(13) Any person who counterfeits military notes; refuses to accept them or in any way hinders the free circulation of military notes by slanderous or seditious utterances.
This is a great example of a Warren Mosler fiat money. According to Mosler, the state's requirement that citizens discharge their tax obligation with a certain intrinsically worthless medium on pain of being shot in the head is sufficient to give that medium a positive value. Likewise, requiring citizens to use the same medium in the course of regular payments and accept it to discharge debts, all on pain of death, would probably have promoted a positive value for intrinsically worthless paper.

Over time, those bits of "forced" paper will enjoy constant purchasing power as long as the issuer withdraws excess currency or adds it when desired. This is the quantity theory of money.

By 1943, however, it seems that the Japanese occupying forces, now being pushed back by the Allied forces, were desperately issuing excess notes to pay for operations. The Filipino monetary system proceeded to run smack dab into Gresham's law. The unit of account, the peso, was defined in terms of two different media—original pesos and military pesos. This meant that debtors could choose to discharge their debts with either. However, if one was perceived to be more valuable than the other, this superior medium would be hoarded and the inferior one used to pay off the debt. Legacy pesos had completely disappeared from circulation by 1943—only war pesos were being used to discharge debts and pay for goods, a decent indicator that the value of Japanese invasion pesos had fallen below that of original pesos. Bad money had chased out the good. (See [1] and [2] for evidence of Gresham's law)

Through 1944 and 1945, the war peso would endure extreme inflation. 10P had been the largest denomination in 1942. The military introduced 100P, 500P, and 1000P notes in subsequent years. In Neil Stephenson's Cryptonomicon, a wide-ranging historical/science fiction novel filled with monetary themes, there's an interesting passage in which Japanese soldier Goto Dengo describes the use of military scrip, probably sometime in 1943 or 1944:
The owner comes over and hands Goto Dengo a pack of Lucky Strikes and a book of matches. "How much?" says Goto Dengo, and takes out an envelope of money that he found in his pocket this morning. He takes the bills out and looks at them: each is printed in English with the words THE JAPANESE GOVERNMENT and then some number of pesos. There is a picture of a fat obelisk in the middle, a monument to Jose P. Rizal that stands near the Manila Hotel.
The proprietor grimaces. "You have silver?"
"Silver? Silver metal?"
"Yes," the driver says.
"Is that what people use?" The driver nods.
"This is no good?" Goto Dengo holds up the crisp, perfect bills.
The owner takes the envelope from Goto Dengo’s hand and counts out a few of the largest denomination of bills, pockets them, and leaves.
Goto Dengo breaks the seal on the pack of Lucky Strikes, raps the pack on the tabletop a few times, and opens the lid.
Japanese invasion currency, already being well on its way to being repudiated, would become completely worthless upon Japan's unconditional surrender in 1945.

Well, not entirely valueless. The second chapter in the life of military scrip begins with The Japanese War Notes Claimants Association of the Philippines, or JAPWANCAP. Formed in 1953 on behalf of Filipinos left holding stranded quantities of worthless Japanese invasion money, JAPWANCAP's mission was to hold both the US and Japanese government's liable for the redemption of war currency (the US had also issued counterfeit Japanese military currency). So while pesos had been valued prior to the war's end upon pain of death, and their value regulated by limiting the quantity outstanding, those same pesos were now valued on the margin as a liability of their issuer. Given the possibility of redemption, an old invasion note was worth more than zero.

Was JAPWANCAP successful? While the case was heard in a United States Court of Claims in 1967, it was thrown out on a technicality, the statute of limitations having had passed. Put simply, the court would not hear a claim that had not been filed within six years of that claim first being accrued, and in JAPWANCAP's case many more years than that had already passed.

This makes one wonder, if Filipinos in 1953 were already convinced that Japanese invasion pesos were the liability of the issuer, and therefore redeemable in some quantity of yen or dollars, did that same motivation also lead them to originally accept new military pesos in 1942? To what degree was the initial acceptance of pesos driven by the threat of force (& subsequent changes in value regulated by their quantity), and to what degree was their value dictated by their status as a liability of a well-backed issuer? That's a question we can never be entirely sure of. But while the force/quantity theory story fits the facts, the liability story does too. The military peso's inflation, for instance, can be attributed to the rising quantity of money, but also to the increasing likelihood of Japan losing the war, a loser's liability's being worth far less than a winner's.

Which brings us to the third chapter in the evolution of Japanese military pesos. Nowadays you can buy the notes on eBay for a few bucks. Their value is no longer dictated by gunpoint, nor by their liability nature, but their existence as a unique commodity, much like gold, bitcoin, or some rare antique.

Friends, not enemies: How the backing and quantity theories co-determine the price level


Kurt Schuler was kind enough to host a Mike Sproul blog post, which I suggest everyone read.

I think Mike's backing theory makes a lot of sense. Financial analysis is about kicking the tires of a issuer's assets in order to arrive at a suitable price for the issuer. If we can price stocks and bonds by analyzing the underlying cash flows thrown off by the issuer's assets, then surely we can do the same with bank notes and bills. After all, notes and bills, like stocks and bonds, are basically claims on a share of firm profits. They are all liabilities. Understand the assets and you've understood the liability (subject to the fine print, of course), how much that liability should be worth in the market, and how its price should change.

Mike presents his backing theory in opposition to the quantity theory of money. But I don't think the two are mutually exclusive. Rather, they work together to explain how prices are determined. By quantity theory, I mean that all things staying the same, an increase in the quantity of a money-like asset leads to a fall in its price.

We can think of a security's market price as being made up of two components. The first is the bit that Mike emphasizes: the value that the marginal investor places on the security's backing. "Backing" here refers to the future cash flows on which the security is a claim. The second component is what I sometimes refer to as moneyness—the additional value that the marginal investor may place on the security's liquidity, where liquidity can be conceived as a good or service that provides ongoing benefits to its holder. This additional value amounts to a liquidity premium.

Changes in backing—the expected flow of future cash flows—result in a rise or fall in a security's overall price. Mike's point is that if changes in backing drive changes in stock and bond prices, then surely they also drive changes in the price of other claims like bank notes and central bank reserves. Which makes a lot of sense.

But I don't think that's the entire story. We still need to deal with the second component, the security's moneyness. Investors may from time to time adjust the marginal value that they attribute to the expected flow of monetary services provided by a security. So even though a money-like security's backing may stay constant, its price can still wobble around thanks to changes in the liquidity premium. Something other than the backing theory is operating behind the scenes to help create prices.

The quantity theory could be our culprit. If a firm issues a few more securities for cash, its backing will stay constant. However, the increased quantity now in circulation will satisfy the marginal buyer's demand for liquidity services. By issuing a few more securities, the firm meets the next marginal buyer's demand, and so on and so on. Each issuance removes marginal buyers of liquidity from the market, reducing the market-clearing liquidity premium that the next investor must pay to enjoy that particular security's liquidity. In a highly competitive world, firms will adjust the quantity of securities they've issued until the marginal value placed on that security's liquidity has been reduced/increased to the cost of maintaining its liquidity, resulting in a rise or fall in the price of the security.

This explains how the quantity theory works in conjunction with the backing theory to spit out a final price. In essence, the quantity theory of money operates by increasing or decreasing the liquidity premium, Mike's backing theory takes care of the rest.



P.S. Kurt Schuler's response to Mike.

BlackBerry needs a Draghi moment


The Blackberry debacle reminds me of another crisis that has passed by the wayside—remember the eurozone's Target2 crisis? The same sorts of forces that caused the Target2 crisis, which was really an intra-Eurosystem bankrun, are also at work in the collapse of Blackberry, which can also be thought of an intra-phone run. By analogy, the same sort of actions that stopped the Target2 crisis should be capable of halting the run on Blackberry phones.

Target2 is the ECB mechanism that allows unlimited amounts of euros held in, say, Greek banks to be converted at par into euros at, say, German banks, and vice versa. As the European situation worsened post credit-crisis, people began to worry about a future scenario in which Ireland, Greece, Spain, Italy, and/or Portugal might either leave the euro or be ejected. If exit occurred, it was expected that these new national currencies, drachmas, punts, and lira, would be worth a fraction of what the euro was then trading for.

The chance that this future "bad" scenario might happen accelerated what had been a steady outflow of deposits from the GIIPS into an all-out run—after all, why would anyone risk being stuck with a Greek euro that might be worthless tomorrow when they could costlessly switch them into a German, Dutch, or Finnish euro today at rate of 1:1? The resulting market process was a reflexive one. Mounting Target2 imbalances caused by the run increased the likelihood of a breakup scenario, amplifying the run and creating even greater imbalances.

What ended the run? ECB President Mario Draghi stepped to the plate in a July 26, 2012 speech and directly addressed what he referred to as convertibility risk.
Within our mandate, the ECB is ready to do whatever it takes to preserve the euro. And believe me, it will be enough... [link]
Draghi's comments, as Gavyn Davies then pointed out, amounted to an explicit commitment to backstop the GIIPS to whatever extent was necessary to quell any fears of euro departure. In essence, he took the future "bad" state of the world in which exit occurred and crushed it under his foot. As this chart shows (this one is good too), the massive inflows into German banks and outflows from the periphery were halted almost to the day of Draghi's speech. After all, if the ECB now guaranteed that Greece and the rest were to remain moored to the union, then a GIIPS Euro was once again equally as good as German, Dutch, or Finnish one.

Blackberry is also encountering a run of sorts as Blackberry users flee into competing phones. In normal times, cell phone brands are like euros—they are homogeneous goods that perform the same task. However, just as fears that Greek euros might one day cease to exist inspired a run into German euros, fears that Blackberry's product line might be discontinued (and left unsupported) are causing an all-out run into iPhones and Androids. After all, why risk being stuck with a legacy Blackberry when, come the expiration of your existing contract, you can costlessly switch into a competing phone that has all the same features, the manufacturer of which is sure to exist a few years from now? Take Pfizer for instance, which recently told its employees that "in response to declining sales, the company [Blackberry] is in a volatile state. We recommend that BlackBerry clients use their BlackBerry devices and plan to migrate to a new device at normal contract expiration."

Blackberry desperately needs to have a Draghi moment whereby the future "bad" scenario—firm dissolution and product discontinuance—is crushed and exorcised, thus putting an end to the run. A long-term commitment with a show of muscle is needed. Has this occurred yet? Last month the company came out with an advertisement titled "You can continue to count on us", highlighting the company's formidable stash of cash and clean balance sheet. A start for sure, but no muscle. Last week, however, investor Prem Watsa stepped forward to play the role of Draghi, recapitalizing Blackberry (along with other investors) to the tune of $1 billion. The infusion should give the firm the raw cash to stay in operation for another few quarters. Is Watsa's line-in-the-sand enough to stop phone buyers from fleeing? Or will shoppers continue to spurn BlackBerry on the chance that more billions will be needed, and Watsa unlikely to stump up the cash? The Globe and Mail quotes Watsa, who gives an accurate account of Blackberry's conundrum:
"Why would you buy a BlackBerry system or a BlackBerry phone if you think the company is not going to survive? Well, that’s out. BlackBerry is here to stay,” he said, adding “There’s no question”
There you go, it's a Draghi moment of sort. Substitute "Blackberry" with "Greek Euro" and you have the exact same message that Draghi conveyed to markets last year in his successful halt of the intra-Eurosystem bank run. Like Greek euros, BlackBerries are presumably here to stay.

The difference between Draghi and Watsa is that a central banker can create any amount of money he or she requires—Watsa, who doesn't have his own printing press, is a little more constrained. However, if Watsa has managed to muster up a true Draghi moment, one that is sufficiently credible with smartphone buyers so as to crush the future "bad" scenario out of existence, then the intra-phone run that has plagued Blackberry is probably over and today may be a good time to own shares.



PS: I don't own BlackBerry shares, but am considering it. Dissuade me if you can, commenters.

1,682 days and all's well


1,682 is the number of days that the Dow Jones Industrial Average has spent rising since hitting rock bottom back in March 6, 2009.

It also happens to be the number of days between the Dow's July 8, 1932 bottom and its March 10, 1937 top. From that very day the Dow would begin to decline, at first slowly, and then dramatically from August to November when it white-knuckled almost 50%, marking one of the fastest bear market declines in history.

Comparisons of our era to 1937 seems apropos. Both eras exhibit near zero interest rates, excess reserves, and a tepid economic recovery characterized by chronic unemployment. Are the same sorts of conditions that caused the 1937 downturn likely to arise 1,682 days into our current bull market?

The classic monetary explanation for 1937 can be found in Friedman & Schwartz's Monetary History. Beginning in August 1936, the Fed announced three successive reserve requirement increases, pushing requirements on checking accounts from 13% to 26% (see chart below). The economy began to decline, albeit after a lag, as banks tried vainly to restore their excess reserve position by reducing lending and selling securities. A portion of the reserve requirement increase was rolled back on April 14, 1938, too late to prevent massive damage being done to the economy. The NBER cycle low was registered in June of that year.


Friedman & Schwartz's second monetary explanation for 1937 has been fleshed out by Douglas Irwin (pdf)(RePEc). In December 1936, FDR began to sterilize foreign inflows of gold and domestic gold production (see next paragraphs for the gritty details). This effectively froze the supply of base money, which had theretofore been increasing at a rate of 15-20% or so a year. Tight money, goes the story, caused the economy to plummet, a decline mitigated by FDR's announcement on February 14, 1938 to partially desterilize (and therefore allow the base to increase again, with limits), further mitigated by an all-out cancellation of the sterilization campaign that April.

Here are the details of how sterilization worked. (If you find the plumbing of central banking tedious, you may prefer to skip to the paragraph that begins with ">>" — I'll bring the 1937 analogy back to 2013 after I'm done with the plumbing). In the 1920s, the supply of base money could be increased in several ways. First, Fed discounting could do the trick, whereby new reserves were lent out upon appropriate collateral. The Fed could also create new reserves and buy either government securities in the open market or bankers acceptances. Lastly, gold was often sold directly to the Fed in exchange for base money. After 1934, all but the last of these four avenues had been closed. Both the Fed's discount rate and its buying rate on acceptances was simply too high to be attractive to banks, and the practice of purchasing government securities on the open market had long since petered out. Only the gold avenue remained.

New legislation in 1934 meant that all domestic gold and foreign gold inflows had to be sold to the Treasury at $35/oz. The Secretary of the Treasury would write the gold seller a cheque drawn on the Treasury's account at the Fed, reducing the Treasury's balance. The Treasury would then print off a gold certificate representing the number of ounces it had purchased, deposit the certificate at the Fed, and have the Fed renew its account balance with brand-spanking new deposits. Put differently, gold certificates were monetized. As the Treasury proceeded to pay wages and other expenses out of its account during the course of business, these new deposits were injected into the banking system.

You'll notice that by 1934 the Treasury, and not the Fed, had become responsible for increasing the base money supply, a situation that may seem odd to us today. As long as the Treasury Secretary continuously bought gold and took gold certificates representing those ounces to the Fed to be monetized, the supply of base money would increase one-for-one as the Treasury drew down its account at the Fed.

The Treasury's decision to sterilize gold inflows in December 1936 meant that although it would continue to purchase gold, it would cease bringing certificates to the Fed to be monetized. The Treasury would pay for each newly mined gold ounce and incoming foreign ounces by first transferring tax revenues and/or the proceeds of bond issuance to its account at the Fed. Only then could it afford to make the payment. Whereas the depositing of gold certificates by the Treasury had resulted in the creation of new base money, neither the transfer of tax revenues nor the proceeds of bond issuance to the Treasury's account would have resulted in the creation of new base.

FDR's sterilization campaign therefore froze the base. Gold was kept "inactive" in Treasury vaults, as Friedman & Schwartz would describe it. The moment the sterilization campaign was reversed (partially in February 1938, and fully in April), certificates were once again monetized, the base began to expand again, and a rebound in stock prices and the broader economy followed not long after.

>> Let's bring this back to the present. Before 2008 the Fed typically increased the supply of base money as it defended its target for the federal funds rate. The tremendous glut of base money created since 2008 and the introduction of interest-on-reserves has given the Fed little to defend, thus shutting the traditional avenue for base money increases. Just as the gold avenue became the only way to increase the base in 1936, quantitative easing has become the only route to get base money into the banking system. With that analogy in mind, FDR's 1936 sterilization campaign very much resembles an end to QE, doesn't it? Both actions freeze of the monetary base. Likewise, last September's decision to avoid tapering is analogous to the 1938 decision to cease sterilization (or to "desterilize") —both of these decisions unfreeze the base.

Who cares if the base is frozen? After all, in 1937 and today, any pause in base creation won't change the fact that there is already a tremendous glut in reserves. A huge pile of snow remains a huge pile, even after it has stopped snowing.

One reason that desterilization and ongoing QE might be effective is because they shape expectations about future monetary policy, and these expectations are acted upon in the present. For instance, say that the market expects the glut of base money to be removed five years in the future. Only then will reserves regain their rare, or "special" status. While a sudden announcement to taper or sterilize will do little to reduce the present glut, it might encourage the market to move up the expected date of the glut's removal by a year or two. Which will only encourage investors in the present to sell assets for soon-to-be rare reserves, causing a deflationary decline in prices. On the other hand, a renewed commitment to QE or desterilization may extend glut-expectations out another few years. This promise of an extended glut period pushes the prospect that reserves might once again be special even further down the road. With the return on base money having been reduced, current holders of the base will react by trying to offload their stash now—thus causing a rise in prices in the present.

If the monetary theories about the 1937 recession are correct, it is no wonder then that 1,682 days into our current bull market investors seem to be so edgy about issues like tapering. Small changes in current purchasing policies may have larger effects on markets than we would otherwise assume thanks to the intentions they convey about future policy.

QE is effective insofar as it is capable of pushing market expectations concerning the future removal of the base money glut ever farther into the future. But once that lift-off point has been pushed so far off into the distant future (say ten years) that the discounted value of going further is trivial, more QE will have minimal impact.

If QE is nearing the end of its usefulness, what happens if we are hit by a negative shock in 2014? Typically when an exogenous shock hits the economy and lowers the expected return on capital, the Fed will quickly reduce the return on base money in order to ensure that it doesn't dominate the return on capital. If the base's return is allowed to dominate, investors will collectively race out of capital into base money, causing a crash in capital markets. The problem we face today is that returns on capital are currently very low and nominal interest rates near zero. Should some event in 2014 cause the expected return on capital to fall below zero, there is little room for the Fed to reduce the return on base money so as to prevent it from dominating the return on capital—especially with interest-on-reserves unable to fall below zero and QE approaching irrelevance. Come the next negative shock, we may be doomed to face an unusually sharp and quick crash in asset prices (like 1937) as the economy desperately tries to adapt to the superior return on base money.

So while I am still somewhat bullish on stocks 1,682 days into the current bull market, I am worried about the potential for contractionary spirals given that we are still at the zero-lower bound. I'm less worried about the Fed implementing something like a 1937-style sterilization campaign. Incoming Fed chair Janet Yellen is well aware of the 1937 event and is unlikely to follow the 1937 playbook. Writes Yellen:
If anything, I’m more concerned that we will be tempted to tighten policy too soon, thereby aborting recovery. That’s just what happened in 1936 when, following two years of robust recovery, the Fed tightened policy because it was worried about large quantities of excess reserves in the banking system. The result? In 1937, the economy plunged back into a deep recession.  -June 30, 2009 [link



Other recent-ish commentary on the 1937 analogy include Paul Krugman, Francois Velde (pdf), Scott Sumner, Lars Christensen, Christina Romer, Charles Calomiris (pdf), Business Insider, and David Glasner.

Rates or quantitites or both


Roaming around the econ blogosphere, I often come across what seems to be a sharp divide between those who think monetary policy is all about the manipulation of interest rates and those who think it comes down to varying the quantity of base money. Either side get touchy when the other accuses its favored monetary policy tool, either rates or quantities, of being irrelevant. From my perch, I'll take the middle road between the two camps and say that both are more-or-less right. Either rates, or quantities, or both at the same time, are sufficient instruments of monetary policy. Actual central banks will typically use some combination of rates and quantities to hit their targets, although this hasn't always been the case.

Just to refresh, central banks carry out monetary policy by manipulating the total return that they offer on deposit balances. This return can be broken down into a pecuniary component and a non-pecuniary component. By varying either the pecuniary return, the non-pecuniary return, or both, a central bank is able to create a disequilibrium, as Steve Waldman calls it, which can only be re-equilibrated by a rise or fall in the price level. If the net return on balances is sweetened, banks will flee assets for balances, causing a deflationary fall in prices. If the return is diminished, banks will flock to assets from balances, pushing prices higher and causing inflation.

The pecuniary return on central bank balances is usually provided in the form of a promise to pay interest, or interest on reserves.

The non-pecuniary return, or convenience yield, is a bit more complicated. I've talked about it before. In short, it's sorta like a consumption return. Because central bank balances are useful in settling large payments, and they are rare, banks find it convenient to hold a small quantity of them as a precaution against uncertain events. This unique convenience provided by scarce balances is consumed over time, much like a fire extinguisher's property as a fire-hedge is consumed though never actually mobilized. By increasing or decreasing the quantity of rare balances, a central banker can decrease or increase the value that banks ascribe to this non-pecuniary return.

Now some examples.

The best example of a central bank resorting solely to the quantity tool in order to execute monetary policy is the pre-2008 Federal Reserve. Before 2008, the Fed was not permitted to pay interest on reserves (IOR). This meant that the only return that Fed balances could offer to banks was a non-pecuniary convenience yield, a point that I described here. By adding to or subtracting from the quantity of balances outstanding the Fed could alter their marginal convenience, either rendering them less convenient so as to drive prices up, or more convenient so as to push prices down.

The Bank of Canada is a good example of a central bank that uses both a quantity tool AND an interest rate tool, though not always both at the same time. Since 1991, according to Mark Sadowski, the BoC has paid interest to anyone who holds overnight balances. This is IOR, although in Canada we refer to it as the deposit rate. In addition to paying this pecuniary return, BoC balances also yield a non-pecuniary return. Banks who hold balances enjoy a stream of consumptive returns, or a convenience yield, that stems from both the rarity of BoC balances and their exceptional liquidity.

The best way to "see" how these two returns might be decomposed is by looking at the short term rental market for Bank of Canada balances, or the overnight market. In Canada, this rate is called CORRA, or the Canadian overnight repo rate. A bank will only part with BoC balances overnight if a prospective borrower promises to sufficiently compensate the lending bank for foregone returns. Assuming that the Bank of Canada's deposit rate is 2%, a potential lender will need to be compensated with a pecuniary return of at least 2% in order to dissuade them from socking away balances at the BoC's deposit facility.

The lender will also need to be compensated for doing without the non-pecuniary return on balances. If the overnight lending rate, CORRA, is 2.25%, then we can back out the rate that a lender expects to earn for renting out the non-pecuniary services provided by balances. Since the lender of balances receives the overnight rate of 2.25% from the borrowing bank, and 2% of this can be considered as compensation for foregoing the 2% pecuniary return on balances, that leaves the remaining 0.25% as compensation to the lender for the loss of the non-pecuniary return.

So in our example, the pecuniary and non-pecuniary returns on BoC balances are 2% and 0.25% respectively, for a total return of 2.25%.

The Bank of Canada meets each six weeks, as Nick Rowe points out, upon which it promises to provide banks with a given return on settlement balances, say 2.25%, for the ensuing six week period. When it next meets, the Bank will  introduce whatever changes to this return that are considered necessary for it to hit its monetary policy targets. The BoC can modify the return by changing either the pecuniary component of the total return, the non-pecuniary component, or some combination of both.

Say it modifies only the non-pecuniary component while leaving their pecuniary return untouched. For instance, with the overnight rate trading at 2.25%, the BoC might announce that it will conduct some open market purchases in order to increase the quantity of balances outstanding, while keeping the deposit rate fixed at 2%. By rendering balances less rare, purchases effectively reduce the non-pecuniary return on balances. As a reflection of this shrinking return, the overnight rate may fall a few basis point, or it may fall all the way to 2%. Whatever the case, the rate at which banks now expect to be compensated for foregoing the non-pecuniary return on balances has been diminished. Banks will collectively try to flee out of overpriced clearing balances into assets, pushing up the economy's price level until balances once again provide a competitive return. This sort of pure quantity effect is the story that the quantities camp likes to emphasize.

The story told by the quantities camp is exactly how the BoC loosened policy between April 2009 and May 2010. At the time, the BoC injected $3 billion in balances *without* a corresponding decrease in the deposit rate. The overnight rate fell from 0.5% until it rubbed up against the 0.25% deposit rate. The lack of a gap between the overnight rate and the deposit rate indicated that the injection had reduced the overnight non-pecuniary return on balances to 0%. After all, if lenders still expected to be compensated for forgoing the non-pecuniary return on balances, they would have required that the overnight rate be above the deposit rate.

The BoC's decision to reduce the overnight non-pecuniary return on balances to 0% would have generated a hot potato effect as banks sold off lower-yielding BoC balances for higher-yielding assets, thus pushing prices higher. A change in quantities, not rates, was responsible for the April 2009 to May 2010 loosening.

Likewise, in June 2010, the BoC tightened by using quantities, not rates. Open market sales sucked the $3 billion in excess balances back in, thereby increasing the marginal convenience yield on central bank balances. The deposit rate remained moored at 0.25%, but the overnight rate jumped back to 0.5%, indicating that the overnight non-pecuniary return on balances had increased from 0% to 0.25%. This sweetening in the return on balances would have inspired a portfolio adjustment away from low-yielding assets into high-yielding central bank balances, a process that would have continued until asset prices had fallen far enough to render investors indifferent once again along the margin between BoC deposits and assets. Once again quantities, not rates, did all the hard work.

While the BoC chose to tighten in June 2010 by changing quantities, it could just as easily have tightened by changing rates. For instance, if it had increased the deposit rate to 0.5% while keeping quantities constant, then the net return on balances would have risen to 0.5%, the same return that was generated in the last paragraph's quantities-only scenario. This sweetening in the return on balances would have caused the exact same chain of portfolio adjustments and falling asset prices that the quantities-only scenario caused.

Alternatively, the BoC could have tightened through some combination of quantities AND rates. It might have increased the deposit rate from 0.25% to 0.4%, and then conducted just enough open market sales to increase the non-pecuniary return on balances from 0% to 0.1%, for a total combined return of 0.5%. The ensuing adjustments would have been no different than if tightening had been accomplished by quantities-only or rates-only.

Putting aside the period between April 2009 and June 2010, does the Bank of Canada normally execute monetary policy via rates or quantities? A bit of both, I'd say. At the end of a six week period, say that the Bank wishes to tighten. It typically tightens by announcing a 0.25% rise in its target for the overnight rate combined with a simultaneous 0.25% rise in the deposit rate. The overnight rate, or the rental rate on clearing balances, will typically rise immediately by 0.25%, reflecting the sweetened return on balances.

Did rates or quantities do the heavy lifting in pushing up the return on balances? Put differently, was it the threat that open market sales might increase the convenience yield on balances that tightened policy, or was it the improvement in the deposit rate? I'd argue that the immediate punch would have been delivered by the change in the deposit rate. CORRA, the rental rate on balances, jumped because overnight borrowers of BoC balances were suddenly required to compensate lenders for the higher pecuniary rate being offered by the BoC on its deposit facility. Quantities don't enter into the picture at all, at least not at first. The rates-only camps seems to be the winner.

However, as the ensuing six-week period plays out, market forces will push the rental rate on BoC balances (CORRA) above or below the Bank's target, indicating an improvement or diminution of the total return on balances. The BoC has typically avoided any incremental variation of the deposit rate to ensure that the rental rate, or return on balances, stays true to target over the six week period. Rather, it has always used quantity changes (or the threat thereof) to modify the non-pecuniary return on balances during that period, thereby steering the rental rate back towards target. First rates, and then quantities, conspire together to create Canadian monetary policy.

To sum up, the Bank of Canada's monetary policy is achieved, it would seem, through a complex combination of rate and quantity adjustments. The rates vs. quantities dichotomy that sometimes pops up on the blogosphere simplifies what is really a more nuanced story. Monetary policy can certainly be carried out by focusing on quantity adjustments to the exclusion of rate adjustments (as was the case with the pre-2008 Fed) or vice versa . However, modern central banks like the Bank of Canada use rates, quantities, and some combination of both, to achieve their targets.



Note: The elephant in the room is the zero-lower bound. But the zero lower bound needn't prevent rates or quantities from exerting an influence on prices. On the rates side of the equation, the adoption of a cash-penalizing mechanism along the lines of what Miles Kimball advocates would allow a central bank to safely push rates below zero. As for the quantity side of the equation,  the threat of Sumnerian permanent increases in the monetary base may not be able to reduce the overnight non-pecuniary return on balances once that rate has hit zero, as Steve Waldman points out... but they can certainly reduce the future non-pecuniary returns provided by balances. Reductions in future non-pecuniary returns should be capable of igniting a hot potato effect, albeit a diminishing one, out of balances and into assets.

An ode to illiquid stocks for the retail investor


Today's go-to advice for the small retail investor is to invest in passive ETFs and index funds. These low cost alternatives are better than investing in high-cost active funds that will probably not beat the market anyway. There's a lot of good sense in the passive strategy.

Here's another idea. If you're a small investor who has a chunk of money that needs to be invested for the long haul, consider investing in illiquid stocks rather than liquid stocks, ETFs, or mutual funds. Pound for pound, illiquid stocks should provide you with a better return than liquid stocks (and ETFs and mutual funds, which hold mostly liquid stocks). Because you're a small fish, you won't really suffer from their relative illiquidity, as long as you're in for the long term. Here's my reasoning.

Take two companies that are identical. They begin their lives with the same plant & equipment and produce the exact same product. Say the risks of the business in which they operate are minimal. They will both be wound up in ten years and distribute all the cash they've earned to shareholders, plus whatever cash they get from selling their plant & equipment. The price of both shares will advance each year at a rate that is competitive with the overall market return until year 10 when the shares are canceled and cash paid out.

The one difference between the two is that for whatever reason, shares in the first company, call it LiquidCo, are far more liquid than shares in the second, DryCo. LiquidCo's bid-ask spread is narrower, it trades far more often, and when it does trade the volumes are much higher.

Given a choice between investing in two identical companies with differing liquidities, investors will always prefer the more liquid one. This is because liquidity provides its own return. Owning a stock with high volumes and low spreads provides the investor with the comfort of knowing that should some unforeseen event arise, they can easily sell their holdings in order to mobilize resources to deal with that event. The liquidity of a stock is, in a sense, consumed over its lifetime, much like a fire extinguisher or a backup generator is consumed, though never actually used. The problem with illiquid stocks, therefore, is that they provide their holders with little to consume.

As a result, the share prices of our two identical firms will diverge from each other at the outset. Since shares of LiquidCo provide an extra stream of consumption over their lifetime, they will trade at a premium to the DryCo shares. However, both shares still promise to pay out the exact same cash value upon termination. This means that as time passes, the illiquid shares need to advance at a more rapid rate than the liquid shares in order to arrive at the same terminal price. See the chart below for an illustration.


The logic behind this, in brief, is that illiquid shares need to provide a higher pecuniary return than liquid shares because they must compensate investors for their lack of a consumption return. This higher pecuniary return is illustrated by DryCo's steeper slope.

Here's where small retail investors come into the picture. Because the capital you're going to be deploying is so small, you can flit in and out of illiquid stocks far easier than behemoths like pensions funds, mutual funds, and hedge funds can. From your perspective, it makes little difference if you invest in LiquidCo or DryCo since your tiny size should allow you to sell either of them with ease. Your choice, therefore, is an easy one. Buy Dryco, the shares will appreciate faster! Thanks to your minuscule size, the market is, in a way, giving you a free ride. You get a higher return without having to sacrifice anything. In short, you get to enjoy a consumer surplus. [1]

Put differently, the consumption return provided by LiquidCo is simply not a valuable good to you as a small and nimble investor. By holding LiquidCo, you're throwing money away by paying for those services. Rather than enjoying a consumer surplus, you're bearing a consumer deficit by holding liquid shares, perhaps without even realizing it. [2]

This advice is of little use to large fish like mutual funds and hedge funds. These players never know when they will face client redemptions necessitating the liquidation of large amounts of stock. Investing in illiquid shares poses a very real inconvenience for them since they are likely to be punished if they try to sell their illiquid portfolio to raise cash to meet redemption requests. Paying the premium to own liquid shares may be the best alternative for a large player.

Because they dominate the market, large players are largely responsible for determining the premium of liquid shares over illiquid ones. Retail investors who directly invest in stocks have become a rare breed, typically opting for mutual funds or ETFs. As such, the premium doesn't reflect retail preferences at all, but the preferences of larger players. Liquid stocks are well-priced for institutional investors but mispriced for the retail investor.

Look over your portfolio. Are you mostly invested in liquid stocks? If so, you may be paying for a flow of liquidity-linked consumption that you simply don't need. Do you hold a lot of mutual funds and ETFs? Both will be biased towards liquid stocks. Mutual fund managers need the flexibility of liquid shares to meet redemptions, and ETFs are usually constructed using popular indexes comprised of primarily liquid stocks. If your liquidity position is overdetermined, it may be time to shift towards the illiquid side of the spectrum. The tough part, of course, is finding what illiquid stocks to buy. But that's a different story.



[1] For this strategy to work in the real world, you really do need to be holding for the long term. My chart shows a steady upward progression. But in the real world, there will be hiccups along the way, and when these happen, illiquid stocks will tend to have larger drawdowns than liquid stocks, even though the underlying earnings of each firm will be precisely similar. As long as you don't put yourself in a position that you're forced to sell during temporary downturns, then you should earn superior returns over the long term.

[2] This is why I like the idea of liquidity options, or "moneyness markets". It makes sense for retail investor to buy LiquidCo if they can resell a portion of the unwanted non-pecuniary liquidity return to some other investor. That way the retail investor owns the slowly appreciating shares of LiquidCo and also earns a stream of revenue for having rented out the non-pecuniary liquidity return. This combination of capital gains and rental revenues should replicate the return they would otherwise earn on DryCo. See this post, which makes the case for "moneyness markets" for the value investor (and helpful comment from John Hawkins).
