This had the effect of reversing the flow of capital to Europe as US capital came home to take advantage of these higher interest rates, which unexpectedly further stoked the stock market boom. After all, why put your money in Germany when you can make 15 percent buying shares in an investment trust and 7 percent in a bank deposit in the USA? The resulting capital flight placed enormous pressure on the German economy, which responded with ever-stricter austerity policies, especially, as we shall see, under Chancellor Brüning in 1930–1931. Deprived of external liquidity—all the money had gone back to the United States—bank runs in Austria and Germany were met with ever-tighter austerity policies in exchange for more loans (that failed to materialize) to stave off the inevitable default.
