The Monetary Breakdown of the West
(Britain and the U.S.) 1926-1931
How to return to the Golden Age? The sensible thing to do would have been to recognize the facts of reality, the fact of the depreciated pound, franc, mark, etc., and to return to the gold standard at a redefined rate: a rate that would recognize the existing supply of money and price levels. The British pound, for example, had been traditionally defined at a weight which made it equal to $4.86. But by the end of World War I, the inflation in Britain had brought the pound down to approximately $3.50 on the free foreign exchange market. Other currencies were similarly depreciated. The sensible policy would have been for Britain to return to gold at approximately $3.50, and for the other inflated countries to do the same. Phase I could have been smoothly and rapidly restored. Instead, the British made the fateful decision to return to gold at the old par of $4.86.  It did so for reasons of British national "prestige," and in a vain attempt to re-establish London as the "hard money" financial center of the world. To succeed at this piece of heroic folly, Britain would have had to deflate severely its money supply and its price levels, for at a $4.86 pound British export prices were far too high to be competitive in the world markets. But deflation was now politically out of the question, for the growth of trade unions, buttressed by a nationwide system of unemployment insurance, had made wage rates rigid downward; in order to deflate, the British government would have had to reverse the growth of its welfare state. In fact, the British wished to continue to inflate money and prices. As a result of combining inflation with a return to an overvalued par, British exports were depressed all during the 1920s and unemployment was severe all during the period when most of the world was experiencing an economic boom.
How could the British try to have their cake and eat it at the same time? By establishing a new international monetary order which would induce or coerce other governments into inflating or into going back to gold at overvalued pars for their own currencies, thus crippling their own exports and subsidizing imports from Britain. This is precisely what Britain did, as it led the way, at the Genoa Conference of 1922, into creating a new international monetary order, the gold-exchange standard.
The gold-exchange standard worked as follows: The United States remained on the classical gold standard, redeeming dollars in gold. Britain and the other countries of the West, however, returned to a pseudo-gold standard, Britain in 1926 and the other countries around the same time. British pounds and other currencies were not payable in gold coins, but only in large-sized bars, suitable only for international transactions. This prevented the ordinary citizens of Britain and other European countries from using gold in their daily life, and thus permitted a wider degree of paper and bank inflation. But furthermore, Britain redeemed pounds not merely in gold, but also in dollars; while the other countries redeemed their currencies not in gold, but in pounds. And most of these countries were induced by Britain to return to gold at overvalued parities. the result was a pyramiding of U.S. on gold, of British pounds on dollars, and of other European currencies on pounds--the "gold-exchange standard," with the dollar and the pound as the two "key currencies."
Now when Britain inflated, and experienced a deficit in its balance of payments, the gold standard mechanism did not work to quickly restrict British inflation. For instead of other countries redeeming their pounds for gold, they kept the pounds and inflated on top of them. Hence Britain and Europe were permitted to inflate unchecked, and British deficits could pile up unrestrained by the market discipline of the gold standard. As for the United States, Britain was able to induce the U.S. to inflate dollars so as not to lose many dollar reserves or gold to the United States.
The point of the gold-exchange standard is that it cannot last; the piper must eventually be paid, but only in a disastrous reaction to the lengthy inflationary boom. As sterling balances piled up in France, the U.S., and elsewhere, the slightest loss of confidence in the increasingly shaky and jerry-built inflationary structure was bound to lead to general collapse. This is precisely what happened in 1931; the failure of inflated banks throughout Europe, and the attempt of "hard money" France to cash in its sterling balances for gold, led Britain to go off the gold standard completely. Britain was soon followed by the other countries of Europe.
