What happened to prices between 2011 and 2021

Between 2011 and 2021, the Consumer Price Index went from 224.939 to 270.97. Cumulatively, prices increased 20.5%, which works out to an average of 1.88% per year. Put differently, a dollar in 2011 bought what $0.83 buys in 2021: the 2011 dollar lost 17.0% of its purchasing power over these 10 years.

2011 brought the fastest inflation of the post-recession recovery. Consumer prices rose 3.2%, roughly double the 2010 pace, and the cause was mostly at the pump and the grocery store. Unrest across the Middle East and North Africa, including the war in Libya, pushed gasoline to an annual average of $3.52 a gallon, the highest yearly figure recorded to that point. Food prices also rose faster than the overall index.

Household budgets did not keep up. The median household income was $50,054, barely above the year before, and the median new home sold for about $227,200. The federal minimum wage stayed at $7.25 and a first-class stamp at 44 cents.

Policy stayed loose. The Federal Reserve kept its policy rate near zero and launched Operation Twist in September to lower long-term rates. Washington spent the summer in a debt-ceiling fight that ended in S&P’s August downgrade of the U.S. credit rating. The inflation spike proved temporary: the 2011 rate was the high point of the early 2010s, and prices grew more slowly in every year that followed until 2017.

The destination year: 2021

In 2021, prices rose 4.7% and $100 from 2011 had the buying power of $120; the year's average CPI of 270.97 is the level behind every 2021 figure on this page.

2021 was the year inflation stopped being background noise. Consumer prices rose 4.7% on average for the year, and the pace kept building as the months went on: by December, the 12-month rate had reached 7.0%, the highest since 1982. The proximate cause was a supply chain that could not keep up with a fast-reopening economy. A global semiconductor shortage choked new car production and pushed used vehicle prices up by more than a third, the single largest line item in the year’s inflation math. Lumber, appliances, and shipping capacity told versions of the same story: demand snapped back faster than factories, ports, and truckers could handle it. Washington added fuel in March with the $1.9 trillion American Rescue Plan, on top of the relief already in the pipeline since 2020. For most of the year, the Federal Reserve called the price surge “transitory,” a temporary reopening effect expected to fade on its own, and held its policy rate near zero. By November, with inflation still climbing, the Fed reversed course and began winding down its bond purchases, the first step toward the rate hikes that would follow in 2022. Gas averaged $3.01 a gallon for the year, up from about $2.17 in 2020, while the federal minimum wage held at $7.25, unchanged since 2009. In hindsight, 2021 reads as the hinge year: the point where “transitory” inflation became the multi-year fight the Fed spent the next two years trying to win.
