What Drove Inflation from 1939 to 1945
World War II: The US entry into World War II following Pearl Harbor transformed the economy virtually overnight. Defense spending surged to over 40% of GDP, unemployment vanished, and inflationary pressures built rapidly. The government responded with comprehensive wage and price controls, rationing, and war bond drives that suppressed spending. Officially measured inflation was moderate, but pent-up demand and informal price pressures were immense.
Postwar Boom: The end of wartime controls unleashed a burst of inflation in 1946–48 as pent-up consumer demand met supply shortages. After that adjustment, the postwar boom settled into a long era of moderate inflation and strong real growth. The GI Bill, suburban expansion, a baby boom, and rising consumer spending drove prosperity. Inflation averaged around 2% per year through most of the 1950s and early 1960s.
