What happened to prices between 1981 and 1999
Between 1981 and 1999, the Consumer Price Index went from 90.9 to 166.6.
Cumulatively, prices increased 83.3%, which works out to an average of
3.42% per year. Put differently, a dollar in 1981 bought what
$0.55 buys in 1999: the 1981 dollar
lost 45.4% of its purchasing power over
these 18 years.
1981 was the year the inflation fever finally broke, at an extraordinary price.
Consumer prices rose 10.3%, the second year of back-to-back double-digit
inflation and the last time the U.S. would see one. To end it, Paul Volcker’s
Federal Reserve drove its policy rate above 19% and let borrowing costs go
where they may: a 30-year mortgage cost more than 18% by autumn, car loans and
business credit froze, and homebuilders mailed the Fed two-by-fours in protest.
The squeeze tipped the economy into recession in July, the deep 1981–82
downturn that would push unemployment past 10%. But it worked. Inflation fell
by nearly half within a year and to under 4% by 1983, the disinflation that
defined the following two decades. Even the price of mailing a letter told the
year’s story: postage went up twice in eight months.
Every 1981 amount converts to 1999 at the same ratio, 1.83: $1,000 becomes
$1,833, and $10,000 becomes $18,328.

Year by year: CPI and the value of $100 from 1981
$100 from 1981 had already become $144 by
1990, on its way to $183 in 1999; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 6.2% in 1982, and the smallest rise was 1.6% in 1998.
In 1999, prices rose 2.2% and $100 from 1981 had the buying
power of $183; the year's average CPI of 166.6 is the level
behind every 1999 figure on this page.
The median household earned about $40,700 in 1999, gas averaged $1.17 a gallon, and a new home
cost roughly $161,000. Inflation ran at 2.2% for the year, ticking back up from 1998’s decade low
as oil prices recovered from their collapse. The decade closed with two changes to the financial
system that would shape the one after it: on January 1, the euro launched as an accounting
currency across 11 European countries, trading alongside national currencies like the French
franc and German mark ahead of physical cash in 2002, and in November, Congress passed the
Gramm-Leach-Bliley Act, tearing down the Depression-era wall between commercial banks, investment
banks, and insurers. Stock markets, meanwhile, were absorbed in a boom of their own: the Nasdaq
surged through the year on soaring internet-stock valuations, and the Federal Reserve raised
interest rates three times in the second half of 1999 partly to cool the exuberance, even as it
pumped extra liquidity into the banking system to guard against any disruption from the Y2K
rollover. A first-class stamp cost 33 cents. Inflation had spent the decade falling from 1990’s
5.4% peak to averages closer to 2-3%, and 1999 closed it out almost exactly where the 1990s as a
whole had settled.
