The Wall Street Crash
The German economy was in decline prior to the Wall Street Crash. There was no growth in German industrial production in 1928-9 and unemployment rose to two and a half million.
On the 24th October, “Black Thursday”, there was panic selling on the New York Stock Exchange reacting to a business crisis in America. Early the following week, “Black Tuesday”, 29th of October, panic selling set in again. 16.4 million shares were sold, a record not surpassed for forty years. Share prices went into freefall. Ten billion dollars was wiped off the value of share prices in one day.
Effects on Germany
As a result American demand for imports collapsed. American banks saw their losses mount and they started calling in their short term loans with which so much of German economy had been financing itself for the past five years.
Firms began to cut back drastically. Industrial production fell quickly and by 1932 it was 40% of its 1929 level. To make matters worse in 1931 a number of Austrian and German banks went out of business. . Unemployment rose from 1.6 million in October 1929 to 6.12 million in February 1932. 33% percent of the workforce were now unemployed.
By 1932 roughly one worker in three was registered as unemployed with rates even higher in industrial areas of Germany. Matters were made worse by the fact that the drastic fall in people’s income caused a collapse in tax revenues. Many soon were not in receipt of unemployment benefits as state governments could not afford to pay it.
It was in this economic chaos that the Nazis and Communists thrived.
Crime and suicide rates rose sharply and many lost hope. People deserted the democratic parties in droves and turned to either the Communists or the Nazis. In the election of 1930, the Nazis made their electoral breakthrough winning 107 deputies while the Communists won 77. Both parties were opposed to the democratic system and used violence against their political opponents. Hitler’s Brownshirts clashed frequently on the streets with their Communist enemies.
