What happened to prices between 1915 and 2017

Between 1915 and 2017, the Consumer Price Index went from 10.1 to 245.12. Cumulatively, prices increased 2326.9%, which works out to an average of 3.18% per year. Put differently, a dollar in 1915 bought what $0.04 buys in 2017: the 1915 dollar lost 95.9% of its purchasing power over these 102 years.

Consumer prices rose 1.0% in 1915, the second straight year of near-flat inflation before the wartime price surges of 1916 through 1918. The year’s defining event had nothing to do with prices directly: a German submarine sank the British liner Lusitania off the Irish coast on May 7, killing 128 Americans and hardening U.S. opinion against Germany two years before the country entered the war. Economically, 1915 was a turning point of a different kind. A recession that had dragged on since 1913 began lifting as Britain and France placed growing orders for steel, munitions, and other war materiel with American manufacturers, and U.S. exports to the Allied powers climbed sharply through the year. That demand would keep building through 1916, eventually pulling prices up with it. On the regulatory side, the Federal Trade Commission opened for business in March, taking on enforcement of the Clayton Antitrust Act that Congress had passed the previous fall. A first-class stamp still cost 2 cents, unchanged since 1885 and still two years from its first wartime increase.

The destination year: 2017

In 2017, prices rose 2.1% and $100 from 1915 had the buying power of $2,427; the year's average CPI of 245.12 is the level behind every 2017 figure on this page.

2017 pushed consumer prices back above the Federal Reserve’s 2% target. The CPI rose 2.1%, the first reading over 2% in five years, helped by a rebound in energy after OPEC’s output cuts and by a storm-related spike at the pump: Hurricane Harvey shut a large part of Gulf Coast refining in late August. Gasoline averaged $2.42 a gallon, up from $2.14 in 2016.

Household incomes kept rising. The median household income reached $61,372, and the median new home sold for about $322,100. The federal minimum wage stayed at $7.25, its eighth year at that level, and a first-class stamp rose to 49 cents.

The Fed raised rates three times, to 1.25–1.50%, and in October began letting its bond holdings shrink. Congress passed the Tax Cuts and Jobs Act in December, lowering the corporate rate to 21%. Even with unemployment near 4%, core inflation stayed under 2%, a puzzle that shaped Fed debates for the next two years.
