What happened to prices between 1984 and 1999
Between 1984 and 1999, the Consumer Price Index went from 103.9 to 166.6.
Cumulatively, prices increased 60.3%, which works out to an average of
3.20% per year. Put differently, a dollar in 1984 bought what
$0.62 buys in 1999: the 1984 dollar
lost 37.6% of its purchasing power over
these 15 years.
1984 was the year the recovery became a boom. Real GDP grew 7.2%, the
fastest calendar-year growth since 1951, as the tax cuts passed in 1981
combined with falling interest rates and rebuilding consumer confidence.
Unemployment, which had topped 10.8% just two years earlier, fell below
7.5%. Inflation ticked up to 4.3% from 3.2% the year before, but nothing
close to a return of the 1970s wage-price spiral: the Federal Reserve under
Paul Volcker kept policy tight enough to hold the line while growth ran hot.
The strength of the expansion, branded “Morning in America” in President
Reagan’s reelection campaign, carried him to a 49-state landslide over
Walter Mondale that November, at the time the widest electoral-vote margin
in U.S. history. For households, the numbers behind the slogan were
concrete: median income rose to about $22,400, and a gallon of gas cost
$1.13, roughly what it had cost three years earlier even as wages kept
climbing. The contrast with 1980, when 13.5% inflation and interest rates
near 20% had defined the economy, could not have been sharper.
Every 1984 amount converts to 1999 at the same ratio, 1.60: $1,000 becomes
$1,603, and $10,000 becomes $16,035.

Year by year: CPI and the value of $100 from 1984
$100 from 1984 had already become $131 by
1991, on its way to $160 in 1999; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 5.4% in 1990, and the smallest rise was 1.6% in 1998.
In 1999, prices rose 2.2% and $100 from 1984 had the buying
power of $160; 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.
