Between 1918 and 1922, the Consumer Price Index went from 15.1 to 16.8.
Cumulatively, prices increased 11.3%, which works out to an average of
2.70% per year. Put differently, a dollar in 1918 bought what
$0.90 buys in 1922.
1918 brought the steepest annual price increase the CPI had recorded:
consumer prices rose 18.0% for the year, edging out 1917’s already sharp
17.4% as the economy stayed at full wartime mobilization for most of the
year. A first-class stamp cost 3 cents, up from 2 cents the previous
November under the War Revenue Act’s wartime tax increases. The war itself
ended on November 11, when Germany signed an armistice with the Allied
powers after more than four years of fighting in Europe, but the inflation
built up over a year and a half of mobilization did not disappear along with
the fighting. The bigger public health story that year was the influenza
pandemic that reached the U.S. in a mild spring wave and then returned that
fall in a far deadlier form, eventually killing roughly 675,000 Americans,
more than the country’s combat losses in the war. It hit factories, docks,
and shops alongside households, adding disruption to an economy already
strained by wartime demand. Prices would keep climbing even after the
armistice, into the postwar surge of 1919.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1918 spending costs in 1922, by category:
Category
Avg. yearly inflation
$100 in 1918 →
All items (CPI-U)
2.70%

Apparel

$98.90
Food

$89.22
Not shown because the BLS began these indexes after 1918: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices fell another 6.1% in 1922, the second straight year of
decline, even as the broader economy climbed out of the Depression of
1920-21 and industrial production rebounded. The CPI had now given back
roughly a third of its wartime runup, though it stayed well above the
1913 baseline. Congress moved to shield that recovery from
foreign competition: the Fordney-McCumber Tariff Act, signed September 21,
raised duties on hundreds of imported goods to some of the highest levels in
U.S. history, a policy meant to protect farmers and manufacturers still
adjusting to postwar prices. Labor tension flared even as prices fell.
Roughly half a million bituminous coal miners struck that April over wage
cuts employers had imposed as prices dropped, and hundreds of thousands of
railroad shop workers walked out in July in a separate dispute over pay and
work rules, together the largest strike wave since 1919. Both disputes
dragged on for months and drew federal mediation before ending without full
concessions for the workers. First-class postage remained at 2 cents.
