What happened to prices between 1938 and 1939

Between 1938 and 1939, the Consumer Price Index went from 14.1 to 13.9. Cumulatively, prices declined 1.4%, which works out to an average of -1.42% per year. Put differently, a dollar in 1938 bought what $1.01 buys in 1939.

Consumer prices fell 2.1% in 1938, reversing most of 1937’s gain and interrupting four straight years of recovery from the Depression’s trough. The National Bureau of Economic Research dates the bottom of the downturn, which had begun that May, to June 1938, a sharp 13-month contraction that briefly pushed unemployment back up near 19%. Even in a year the economy was shrinking again, Congress passed one of the New Deal’s most lasting reforms. The Fair Labor Standards Act, signed June 25 and effective that October, established the first federal minimum wage, 25 cents an hour, capped the standard workweek at 44 hours with time-and-a-half overtime beyond it, and restricted the employment of children in most industries. The wage floor and hours limits applied only to workers engaged in interstate commerce at first, but they set a precedent that would expand in the decades that followed. Consumer prices stood 42.4% above their 1913 level and 17.5% below their 1929 peak, evidence of how far the recovery still had to go even eight years after the Depression began.

The destination year: 1939

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending.
