What happened to prices between 1934 and 1990

Between 1934 and 1990, the Consumer Price Index went from 13.4 to 130.7. Cumulatively, prices increased 875.4%, which works out to an average of 4.15% per year. Put differently, a dollar in 1934 bought what $0.10 buys in 1990: the 1934 dollar lost 89.7% of its purchasing power over these 56 years.

Consumer prices rose 3.1% in 1934, the first annual increase since 1926; every year from 1927 through 1933 had been flat or falling, so the turn marked a real break after eight years without a single gain. Currency policy did some of the work. The Gold Reserve Act, signed January 30, formally devalued the dollar by raising the official price of gold from $20.67 to $35 an ounce, part of the administration’s deliberate effort to reflate prices after four straight years of deflation. Financial regulation tightened at the same time: the Securities Exchange Act of June 6 created the Securities and Exchange Commission to police stock exchanges and enforce disclosure rules, a direct response to the speculation blamed for the 1929 crash. The recovery was fragile and unevenly felt, especially on the Great Plains, where drought had turned overplowed farmland to dust. Over May 9-11, high winds lifted an estimated 350 million tons of topsoil into the air, darkening skies as far away as Washington and New York and giving city readers who had never seen a wheat field a first glimpse of the disaster building in Kansas, Oklahoma, and Texas. Consumer prices stood 35.4% above their 1913 level, still well below the 1929 peak but rising for the first time since the Depression began. First-class postage held at 3 cents.
