Between 1915 and 1934, the Consumer Price Index went from 10.1 to 13.4.
Cumulatively, prices increased 32.7%, which works out to an average of
1.50% per year. Put differently, a dollar in 1915 bought what
$0.75 buys in 1934.
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 headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1915 spending costs in 1934, by category:
Category
Avg. yearly inflation
$100 in 1915 →
All items (CPI-U)
1.50%
$133
Apparel
1.58%
$135
Food
0.78%
$116
Not shown because the BLS began these indexes after 1915: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 3.1% 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.
