What happened to prices between 2009 and 2023
Between 2009 and 2023, the Consumer Price Index went from 214.537 to 304.702.
Cumulatively, prices increased 42.0%, which works out to an average of
2.54% per year. Put differently, a dollar in 2009 bought what
$0.70 buys in 2023: the 2009 dollar
lost 29.6% of its purchasing power over
these 14 years.
2009 is the rarest kind of year in the modern price data: one where the cost
of living went down. The CPI fell 0.4%, the first full-year deflation
since 1955, as the Great Recession hollowed out demand and oil unwound from
its $147 spike the summer before. Gasoline that had cost over $4 a gallon in
July 2008 averaged $2.35 in 2009, and that energy collapse dragged the
12-month inflation rate to −2.1% by July, the deepest reading since 1950.
Policymakers treated falling prices not as relief but as a warning: deflation
raises the real weight of debt precisely when households are drowning in it,
which is why the Federal Reserve pinned interest rates near zero, began buying
bonds by the hundreds of billions, and Washington passed a $787 billion
stimulus. The medicine took: prices stabilized within a year, and 2009 remains
the textbook case of why central banks fear deflation more than moderate
inflation.
Every 2009 amount converts to 2023 at the same ratio, 1.42: $1,000 becomes
$1,420, and $10,000 becomes $14,203.

Year by year: CPI and the value of $100 from 2009
$100 from 2009 had already become $112 by
2016, on its way to $142 in 2023; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 8.0% in 2022, and the smallest rise was 0.1% in 2015.
In 2023, prices rose 4.1% and $100 from 2009 had the buying
power of $142; the year's average CPI of 304.702 is the level
behind every 2023 figure on this page.
2023 was the year inflation came down without a recession. Consumer prices
rose 4.1% on average, roughly half of 2022’s 8.0%, and the December-to-December
rate fell to 3.4%. Gasoline averaged $3.52 a gallon, well below the 2022
average, and supply-chain pressure on goods eased. Shelter, restaurant meals,
and other services stayed expensive, so the CPI kept rising at a rate well
above the pre-pandemic pace.
The Federal Reserve completed its rate-hiking campaign in July, taking the
policy rate to 5.25–5.50%, the highest level in 22 years. The effects showed
up in banking: Silicon Valley Bank failed in March after rate increases eroded
the value of its bond portfolio, the second-largest bank failure in U.S.
history at the time. Despite that, unemployment stayed under 4% all year.
Median household income was $80,610 according to the Census Bureau. The
federal minimum wage stayed at $7.25, and a first-class stamp rose to 66 cents
in July.
