Currency Devaluations of the 1930s

newworldeconomics.com /
For some reason, I have the urge to work on this topic a little more. I made available the raw data here:
April 15, 2012: Foreign Exchange Rates 1914-1941
The basic story of this time period, 1920-1940 is something like this: A lot of currencies left the gold standard during WWI, including the U.S. to a small degree. Some then had hyperinflation in the early 1920s. During the mid-1920s, these currencies are repegged to gold. The Great Depression begins. I thought Germany was the first of the big countries to devalue in August of 1931, but it turns out that was wrong. Germany’s government defaulted on its debt that month, and imposed heavy currency controls, but the currency was not (officially) devalued. Thus, Britain was the first of the big countries to devalue, in September 1931. Because the British pound was the world’s premier international currency, much like the dollar is today, many countries followed Britain’s lead and devalued simultaneously or soon after. Japan followed in December 1931, basically to return the yen exchange rate to its pre-devaluation level.
These are annual averages, which unfortunately do not capture some of these events well. The September 1931 devaluations, for example, get averaged into 1931, so the 1931 averages show only a slight decline for the full year. The U.S. devalues in 1933 of course, and repegs to gold in 1934 at $35/oz.
I suppose some of the points made here are that most countries devalued their currencies around the late 1931 timeframe, if not earlier in some instances. This put “beggar thy neighbor” trade pressures on all the non-devaluing countries. When the world’s premier international currency, in this case the British pound, is devalued, usually there are a lot of copycats. The result is that nearly all countries also devalued, if only to restore exchange rates to somewhere near their pre-devaluation levels.
I’ll have the remainder of the countries next week.
