What happened to prices between 1966 and 1998

Between 1966 and 1998, the Consumer Price Index went from 32.4 to 163. Cumulatively, prices increased 403.1%, which works out to an average of 5.18% per year. Put differently, a dollar in 1966 bought what $0.20 buys in 1998.

Consumer prices rose 2.9% in 1966, nearly double 1965’s 1.6% as Vietnam War spending kept climbing without an offsetting tax increase, pushing the economy closer to capacity and prices higher along with it. Medicare coverage took effect that July 1, extending federal health insurance to roughly 19 million Americans age 65 and older under the program signed into law the year before. The Federal Reserve had already moved to cool the overheating economy, raising its discount rate the previous December over White House objections; the tightening carried into 1966 as the first postwar credit crunch, freezing parts of the housing and municipal bond markets even as inflation kept climbing. Congress widened the wage floor’s reach that September 23, when the Fair Labor Standards Amendments of 1966 set a $1.40 minimum wage effective the following February and extended coverage to roughly 9 million more workers in retail, hospitals, schools, and other services not previously covered. Consumer prices finished 1966 227.3% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour for the rest of the year.
