Between 1928 and 1934, the Consumer Price Index went from 17.1 to 13.4.
Cumulatively, prices declined 21.6%, which works out to an average of
-3.98% per year. Put differently, a dollar in 1928 bought what
$1.28 buys in 1934.
Consumer prices fell 1.7% in 1928, the second straight year of mild decline
even as the stock market climbed sharply, a widening gap between asset
prices and the cost of living that later economists pointed to as an early
warning sign. The Federal Reserve tightened policy repeatedly over the year,
raising its discount rate in an effort to slow the flood of borrowed money
pouring into stock purchases without derailing the broader economy, a
balancing act it ultimately failed to manage. Herbert Hoover won the
presidential election that November, defeating Democrat Al Smith on a
platform built around continuing the prosperity of the Coolidge years; few
voters or policymakers anticipated how quickly that prosperity would end.
First-class postage remained at 2 cents, a price that had now held for nine
straight years.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1928 spending costs in 1934, by category:
Category
Avg. yearly inflation
$100 in 1928 →
All items (CPI-U)
-3.98%
$78.36
Apparel
-3.17%
$82.40
Food
-5.51%
$71.17
Not shown because the BLS began these indexes after 1928: 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.
