What happened to prices between 2017 and 2018
Between 2017 and 2018, the Consumer Price Index went from 245.12 to 251.107.
Cumulatively, prices increased 2.4%, which works out to an average of
2.44% per year. Put differently, a dollar in 2017 bought what
$0.98 buys in 2018: the 2017 dollar
lost 2.4% of its purchasing power over
these 1 years.
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.
Every 2017 amount converts to 2018 at the same ratio, 1.02: $1,000 becomes
$1,024, and $10,000 becomes $10,244.

Year by year: CPI and the value of $100 from 2017
$100 from 2017grew to $102 by 2018; each row
shows the CPI, that year's inflation rate, and the running value.
In 2018, prices rose 2.4% and $100 from 2017 had the buying
power of $102; the year's average CPI of 251.107 is the level
behind every 2018 figure on this page.
2018 was the peak of the late-2010s expansion. Consumer prices rose 2.4%,
the fastest since 2011, with gasoline averaging $2.72 a gallon after a summer
high. Unemployment fell to 3.7% in September, the lowest since 1969, and median
household income reached $63,179. The median new home sold for about $331,800,
and a first-class stamp cost 50 cents. The federal minimum wage was still $7.25.
Trade policy became a price factor for the first time in decades. New tariffs
on steel, aluminum, and a growing list of Chinese goods raised costs for
manufacturers and some consumer products, and retaliation cut into exports of
soybeans and other farm goods.
The Federal Reserve, led from February by Jerome Powell, raised rates four
times to 2.25–2.50%. A stock-market drop of nearly 20% in the fourth quarter
led the Fed to signal a pause in early 2019. Oil fell from over $75 a barrel in
October to below $50 by December, which pulled headline inflation lower going
into the next year.
