Between 1917 and 1937, the Consumer Price Index went from 12.8 to 14.4.
Cumulatively, prices increased 12.5%, which works out to an average of
0.59% per year. Put differently, a dollar in 1917 bought what
$0.89 buys in 1937.
1917 is when World War I inflation stopped being a background trend and
became the dominant fact of American economic life. Consumer prices rose
17.4% for the year, more than double the previous year’s already sharp
increase, as the country’s April 6 entry into the war layered federal war
spending on top of an economy already strained by military demand and
worker shortages. Congress paid for the war with the War Revenue Act that
October, which sharply raised income taxes, created a new tax on wartime
business profits, and, in a small but very visible change for ordinary
households, raised the cost of a first-class stamp from 2 cents to 3 cents
that November, the rate’s first move since 1885. Herbert Hoover took over
the new Food Administration in August and asked Americans to conserve food
voluntarily rather than face formal rationing, a campaign that became
famous enough that “Hooverize” entered the language as a verb for cutting
back. None of it slowed prices much: the 17.4% increase would be topped
again the very next year, in 1918.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1917 spending costs in 1937, by category:

Not shown because the BLS began these indexes after 1917: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 3.6% in 1937, the fastest pace since before the
Depression and the fourth straight year of gains, leaving prices 10.8% above
their 1933 trough though still 15.8% below the
1929 peak. The recovery did not last the year. The National
Bureau of Economic Research dates a new business cycle peak to that May, the
start of what became known as the Recession of 1937-38. Policy tightened on
two fronts at once: the Federal Reserve had doubled bank reserve
requirements over the preceding year to head off inflation it worried was
building, and the federal government pulled back its own spending even as
new Social Security payroll taxes began draining money from paychecks
months before the first benefit checks went out. Together they choked off a
recovery that had not yet reached its pre-Depression footing. Not every
milestone that year was economic. The Golden Gate Bridge opened to traffic
on May 27 after four years of construction, at the time the longest
suspension bridge span in the world, a rare bright spot in a year that would
end with the economy sliding backward again. First-class postage held at 3
