How does monetary policy react during a war?
Since we are interested in the ECB’s reaction to the war in Ukraine, we seek to determine what central banks did in the past during wars when faced with a “war economy”: sharp increase in government spending, high inflation. We therefore look at the monetary policy conducted in the United States during the Second World War, the Korean War (1950-1953) and the Vietnam War (1963-1975). We see that the Federal Reserve has not always had the same reaction: During the Second World War and the Korean War, it did not react to inflation; But during the Vietnam War, it did react to inflation.
