While currency in circulation has grown slightly, there's been an impressive 17-fold increase in bank reserves. The federal-funds target rate now stands at an all-time low range of zero to 25 basis points, with the 91-day Treasury bill yield equally low. All this has been done to avoid a liquidity crisis and a repeat of the mistakes that led to the Great Depression.
Even with this huge increase in the monetary base, Fed Chairman Ben Bernanke has reiterated his goal not to repeat the mistakes made back in the 1930s by tightening credit too soon, which he says would send the economy back into recession. The strong correlation between soaring unemployment and falling consumer prices in the early 1930s leads Mr. Bernanke to conclude that tight money caused both. To prevent a double dip, super easy monetary policy is the key.
While Fed policy was undoubtedly important, it was not the primary cause of the Great Depression or the economy's relapse in 1937. The Smoot-Hawley tariff of June 1930 was the catalyst that got the whole process going. It was the largest single increase in taxes on trade during peacetime and precipitated massive retaliation by foreign governments on U.S. products. Huge federal and state tax increases in 1932 followed the initial decline in the economy thus doubling down on the impact of Smoot-Hawley. There were additional large tax increases in 1936 and 1937 that were the proximate cause of the economy's relapse in 1937.
In 1930-31, during the Hoover administration and in the midst of an economic collapse, there was a very slight increase in tax rates on personal income at both the lowest and highest brackets. The corporate tax rate was also slightly increased to 12% from 11%. But beginning in 1932 the lowest personal income tax rate was raised to 4% from less than one-half of 1% while the highest rate was raised to 63% from 25%. (That's not a misprint!) The corporate rate was raised to 13.75% from 12%. All sorts of Federal excise taxes too numerous to list were raised as well. The highest inheritance tax rate was also raised in 1932 to 45% from 20% and the gift tax was reinstituted with the highest rate set at 33.5%.
But the tax hikes didn't stop there. In 1934, during the Roosevelt administration, the highest estate tax rate was raised to 60% from 45% and raised again to 70% in 1935. The highest gift tax rate was raised to 45% in 1934 from 33.5% in 1933 and raised again to 52.5% in 1935. The highest corporate tax rate was raised to 15% in 1936 with a surtax on undistributed profits up to 27%. In 1936 the highest personal income tax rate was raised yet again to 79% from 63%—a stifling 216% increase in four years. Finally, in 1937 a 1% employer and a 1% employee tax was placed on all wages up to $3,000.
