What happened to prices between 2009 and 2017
Between 2009 and 2017, the Consumer Price Index went from 214.537 to 245.12.
Cumulatively, prices increased 14.3%, which works out to an average of
1.68% per year. Put differently, a dollar in 2009 bought what
$0.88 buys in 2017: the 2009 dollar
lost 12.5% of its purchasing power over
these 8 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 2017 at the same ratio, 1.14: $1,000 becomes
$1,143, and $10,000 becomes $11,426.

Year by year: CPI and the value of $100 from 2009
$100 from 2009 had already become $109 by
2013, on its way to $114 in 2017; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 3.2% in 2011, and the smallest rise was 0.1% in 2015.
In 2017, prices rose 2.1% and $100 from 2009 had the buying
power of $114; the year's average CPI of 245.12 is the level
behind every 2017 figure on this page.
2017 pushed consumer prices back above the Federal Reserve’s 2% target. The
CPI rose 2.1%, the first reading over 2% in five years, helped by a rebound
in energy after OPEC’s output cuts and by a storm-related spike at the pump:
Hurricane Harvey shut a large part of Gulf Coast refining in late August.
Gasoline averaged $2.42 a gallon, up from $2.14 in 2016.
Household incomes kept rising. The median household income reached $61,372,
and the median new home sold for about $322,100. The federal minimum wage
stayed at $7.25, its eighth year at that level, and a first-class stamp rose
to 49 cents.
The Fed raised rates three times, to 1.25–1.50%, and in October began
letting its bond holdings shrink. Congress passed the Tax Cuts and Jobs Act
in December, lowering the corporate rate to 21%. Even with unemployment near
4%, core inflation stayed under 2%, a puzzle that shaped Fed debates for the
next two years.
