What happened to prices between 1986 and 1999
Between 1986 and 1999, the Consumer Price Index went from 109.6 to 166.6.
Cumulatively, prices increased 52.0%, which works out to an average of
3.27% per year. Put differently, a dollar in 1986 bought what
$0.66 buys in 1999: the 1986 dollar
lost 34.2% of its purchasing power over
these 13 years.
1986 delivered the decade’s biggest one-year drop in inflation, and it came
almost entirely from a single source: oil. Saudi Arabia abandoned its policy
of restraining output to prop up prices, and world crude collapsed from
about $27 a barrel to under $10 by midyear. Gasoline, which had averaged
$1.12 a gallon in 1985, fell to 86 cents. With energy costs plunging,
headline CPI inflation for the year came in at just 1.9%, the lowest annual
rate since 1965 and a striking bookend to 1980’s 13.5% peak. The relief was
uneven: prices for most goods and services outside energy kept rising at a
moderate pace, so households that didn’t drive much or heat with oil felt
less of the difference. In October, Congress passed the Tax Reform Act of
1986, a bipartisan overhaul that cut the top individual income tax rate from
50% to 28% while closing many deductions and shelters, the broadest rewrite
of the federal tax code since World War II. Between cheap gas and falling
interest rates, 1986 read like proof that the inflationary 1970s were a
closed chapter, six years after the U.S. economy had felt anything but
calm.
Every 1986 amount converts to 1999 at the same ratio, 1.52: $1,000 becomes
$1,520, and $10,000 becomes $15,201.

Year by year: CPI and the value of $100 from 1986
$100 from 1986 had already become $128 by
1992, on its way to $152 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 1986 had the buying
power of $152; 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.
