John Cochrane thinks that central banks can attain the price-stability of the gold standard without actually having a gold standard:
While many people believe the United States should adopt a gold standard to guard against inflation or deflation, and stabilize the economy, there are several reasons why this reform would not work. However, there is a modern adaptation of the gold standard that could achieve a stable price level and avoid the many disruptions brought upon the economy by monetary instability.
The solution is pretty simple. A gold standard is ultimately a commitment to exchange each dollar for something real. An inflation-indexed bond also has a constant, real value. If the Consumer Price Index (CPI) rises to 120 from 100, the bond pays 20% more, so your real purchasing power is protected. CPI futures work in much the same way. In place of gold, the Fed or the Treasury could freely buy and sell such inflation-linked securities at fixed prices. This policy would protect against deflation as well as inflation, automatically providing more money when there is a true demand for it, as in the financial crisis.
The obvious point is that the CPI is a relatively poor indicator of inflation and bubbles. During Greenspan’s tenure in charge of the Federal Reserve, huge quantities of new liquidity were created, much of which poured into housing and stock bubbles. CPI doesn’t include stock prices, and it doesn’t include housing prices; a monetary policy that is fixed to CPI wouldn’t be able to respond to growing bubbles in either sector. Cochrane is not really advocating for anything like the gold standard, just another form of Greenspanesque (mis)management.
Historically, what the gold standard meant was longer-term price stability, punctuated by frequent and wild short-term swings in purchasing power:
In its simplest form (the gold coin standard), gold constrains the monetary base to the amount of gold above ground. The aim is to prevent bubble-formation (in other words, monetary growth beyond the economy’s inherent productivity) because monetary growth would be limited to the amount of gold dug out of the ground, and the amount of gold dug out of the ground is limited to the amount of productivity society can afford to spend on mining gold.
Unfortunately, although gold levels are fixed, levels of credit creation are potentially infinite (and even where levels of credit creation are fixed by reserve requirements, shadow credit creation can still allow for explosive credit growth as happened after the repeal of Glass-Steagall). For example, the 1920s — a period with a gold standard — experienced huge asset bubble formation via huge levels of credit creation.
In any case, I don’t think that the current monetary regimes (or governments — who love to have the power to monetise debt) will ever change their minds. The overwhelming consensus of academic economists is that the gold standard is bad and dangerous.
In a recent survey of academic economists, 93% disagreed or strongly disagreed with this statement:
If the US replaced its discretionary monetary policy regime with a gold standard, defining a “dollar” as a specific number of ounces of gold, the price-stability and employment outcomes would be better for the average American.
That question is skewed. A gold standard can also be a discretionary regime; gold can be devalued, it can be supplemented with silver, and it can be multiplied by credit. And the concept of “price-stability” is hugely subjective; the Fed today defines “price stability” as a consistent 2% inflation (which on an infinite timeline correlates to an infinite level of inflation — the only stable thing being the rate at which the purchasing power of a dollar decreases).
If anything, the events of 2008 — which I interpret as a predictable and preventable housing, securitisation, and debt bubble stemming very much from central bank mismanagement of the money supply under Greenspan — secured the reputation of central banking among academic economists, because the bailouts, low rates and quantitative easing have prevented the feared debt-deflation that Milton Friedman and Ben Bernanke postulated as the thing that prolonged and worsened the Great Depression.
The Japanese example shows that crashed modern economies with excessive debt loads can remain stagnant for long periods of time. My view is that such nations are in a deleveraging trap; Japan (and more recently the Western nations) hit an excessive level of debt relative to GDP and industry at the peak of the bubble. As debt rises, debt servicing costs rise, leaving less income for investment, consumption, etc.
Throughout Japan’s lost decade, and indeed the years that followed, total debt levels (measured in GDP) have remained consistently high. Simply, the central bank did not devalue by anywhere near enough to decrease the real debt load, but nor have they devalued too little to result in a large-scale liquidation episode. They have just kept the economy in stasis, with enough liquidity to keep the debt serviceable, and not enough to really allow for severe reduction. The main change has been a transfer of debt from the private sector, to the public sector (a phenomenon which is also occurring in the United States and United Kingdom).
Eventually — because the costs of the deleveraging trap makes organically growth very difficult — the debt will either be forgiven, inflated or defaulted away. Endless rounds of tepid QE (which is debt additive, and so adds to the debt problem) just postpone that difficult decision. The deleveraging trap preserves the value of past debts at the cost of future growth.
Under the harsh discipline of a gold standard, such prevarication is not possible. Without the ability to inflate, overleveraged banks, individuals and governments would default on their debt. Income would rapidly fall, and economies would likely deflate and become severely depressed.
Yet liquidation is not all bad. The example of 1907 — prior to the era of central banking — illustrates this.
As the WSJ noted:
The largest economic crisis of the 20th century was the Great Depression, but the second most significant economic upheaval was the panic of 1907. It was from beginning to end a banking and financial crisis. With the failure of the Knickerbocker Trust Company, the stock market collapsed, loan supply vanished and a scramble for liquidity ensued. Banks defaulted on their obligations to redeem deposits in currency or gold.
Milton Friedman and Anna Schwartz, in their classic “A Monetary History of the United States,” found “much similarity in its early phases” between the Panic of 1907 and the Great Depression. So traumatic was the crisis that it gave rise to the National Monetary Commission and the recommendations that led to the creation of the Federal Reserve. The May panic triggered a massive recession that saw real gross national product shrink in the second half of 1907 and plummet by an extraordinary 8.2% in 1908. Yet the economy came roaring back and, in two short years, was 7% bigger than when the panic started.
Although liquidation episodes are painful, the clear benefit is that a big crash and depression clears out old debt. Under the present regimes, the weight of old debt remains a burden to the economy.
But Cochrane talking about imposing a CPI-standard (or Greenspan talking about returning to the gold standard) is irrelevant; the bubble has happened, it burst, and now central banks must try to deal with the fallout. Even after trillions of dollars of reflation, economies remain depressed, unemployment remains elevated and total debt (relative to GDP) remains huge. The Fed — almost 100 years old — is in a fight for its life. Trying to balance the competing interests of creditors — particularly those productive foreign nations like China that produce much of America’s consumption and finance her deficits — against future growth is a hugely challenging task. The dangers to Western economies from creditor nations engaging in punitive trade measures as a retaliatory measure to central bank debasement remain large (and the rhetoric is growing fiercer). Bernanke is walking a tightrope over alligators.
In any case even if a gold standard were to be reimposed in the future, history shows that it is unlikely to be an effective stop against credit bubbles. Credit bubbles happen because value is subjective and humans are excitable, and no regime has proven itself capable of fully guarding against that. Once a credit bubble forms, the possibilities are the same — liquidation, inflation or debt forgiveness. Today, central banks must eventually make a choice, or the forces of history will decide instead.
