Some years ago I published a paper on the banking theory and policy views of the important twentieth-century economist Friedrich A. Hayek, entitled "Why Didn't Hayek Favor Laissez Faire in Banking?" Very recently, working on a new paper on Hayek's changing views of the gold standard, I discovered an important but previously overlooked passage on banking policy in a 1925 article by Hayek entitled "Monetary Policy in the United States After the Recovery from the Crisis of 1920." I missed the passage earlier because the full text of Hayek's article became available in English translation only in 1999, the same year my article appeared, in volume 5 of his Collected Works. Only an excerpt had appeared in translation in Money, Capital, and Fluctuations, the 1984 volume of Hayek's early essays.
Hayek wrote the article in December 1924, very early in his career. In May 1924 he had returned from a post-doctoral stay in New York City and had begun participating in the Vienna seminar run by Ludwig von Mises. It is safe to say that the passage I am about to quote reflects Mises' influence, since the article cites him, and in many ways takes positions opposite to those Hayek had taken in an earlier article that he wrote while still in New York.
The main topic of the 1925 article is the Federal Reserve's policies in the peculiar postwar situation in which, as Hayek put it, the US "emerged from the war … as the only country of importance to have retained the gold standard intact." The US had received "immense amounts" of European gold during and since the war (Hayek documents this movement with pertinent statistical tables and charts), and now held a huge share of the world's gold reserves — more gold reserves than the Fed knew what to do with. European currencies, having left the gold standard to use inflationary finance during the First World War, and not having yet resumed direct redeemability, were for the time being pegged to the gold-redeemable US dollar. This was a new and unsettled "gold exchange standard," unlike the prewar classical gold standard in which major nations redeemed their liabilities directly for gold and held their own gold reserves. Rather than delve into what Hayek had to say about that topic, I want to convey what he said about banking.
In section 8 of the article (pp. 145-47 in the 1999 translation), Hayek gives a favorable evaluation of free banking as against central banking. Having overlooked this passage, I had previously thought that Hayek first addressed free banking in his 1937 book Monetary Nationalism and International Stability. Hayek does not embrace free banking as an ideal, first-best system, because he thought it prone to over-issue (as I discussed in my 1999 article based on Hayek's other writings). But he criticizes the Federal Reserve Act for relaxing rather than strengthening the prior system's constraints against excess credit expansion by American commercial banks.
Hayek begins the passage with a caution that the intended result of creating a central bank, when the intention is to avoid or mitigate financial crises, need not be the actual result:
It cannot be taken for granted that a central banking system is better suited to prevent disturbances in the economy stemming from excessive variations in the volume of available bank credit than a system of independent and self-reliant commercial banks run on purely private enterprise (liquidity, profitability) lines.
By standing ready to help commercial banks out of liquidity trouble, central banks give "added incentive … to commercial banks to extend a large volume of credit." In modern terminology, a lender of last resort creates moral hazard in commercial banking. A free banking system (my phrase, not his) restrains excessive credit creation by fear of failure:
In the absence of any central bank, the strongest restraint on individual banks against extending excessive credit in the rising phase of economic activity is the need to maintain sufficient liquidity to face the demands of a period of tight money from their own resources.
Hayek's belief that the pre-Fed US system did not restrain credit creation firmly enough is understandable in light of the five financial panics during the fifty years of the federally regulated "National Banking system" that prevailed between the Civil War and the First World War. He might have noted, however, that the National Banking system was a system legislatively hobbled by branching and note-issue restrictions rather than a free banking system or a system "run on purely private enterprise lines." The Canadian banking system, lacking those restrictions, did not experience financial panics during this period (or even during the Great Depression) despite having an otherwise similar largely agricultural economy.
Despite the flawed character of the pre-Fed system, Hayek judged that the Federal Reserve Act made the situation worse rather than better by loosening the prevailing constraints against unwarranted credit expansions:
Had banking legislation had the primary goal to prevent cyclical fluctuations, its main efforts should have been directed towards limiting credit expansion, perhaps along the lines proposed — in an extreme, yet ineffective way — by the theorists of the "currency school," who sought to accomplish this purpose by imposing limitations upon the issuing of uncovered notes. … Largely because of the public conception of their function, central banks are intrinsically inclined to direct their activities primarily towards easing the money market, while their hands are practically tied when it comes to preventing economically unjustified credit extension, even if they should favour such an action. …
This applies especially to a central banking mechanism superimposed on an existing banking system. … The American bank reform of 1913-14 followed the path of least resistance by relaxing the existing rigid restraints of the credit system rather than choosing the alternative path …
Thus the Fed was granted the power to expand money and credit, a power that "was fully exploited during and immediately after the war," not waiting for a banking liquidity crisis. The annual inflation rate in the United States, as measured by the CPI, exceeded 20 percent in 1917, and remained in double digits for the next three years (17.5, 14.9, and 15.8) before the partial reversal of 1921. Hayek (p. 147) observed ruefully "how large an expansion of credit took place under the new system without exceeding the legal limits and without activating in time automatic countermeasures forcing the banks to restrict credit." He concluded: "There can be no doubt that the introduction of the central banking system increased the leeway in the fluctuations of the volume of bank credit in use."
Here Hayek reminds us that a less-regulated banking system does not need to be perfect to be better than even well-intentioned heavier regulatory intervention. Good intentions do not equal good results in bank regulation.
