2021–2023· Crisis or event

US inflation jumped from under 2% to 9.1% by June 2022, the highest in 40 years, before easing toward 3%.
See it on the Money & Finance map →How it works
Reopening demand, about $5 trillion in relief and fast money growth met broken supply chains: chip shortages, clogged ports and missing workers. Used-car prices rose about 45% in a year. Russia's 2022 invasion of Ukraine spiked energy and food prices, and rents followed. The Fed raised rates from near zero to 5.25–5.50% between March 2022 and July 2023. CPI inflation fell to about 3% by mid-2023 without a recession, but prices stayed higher.
Why it matters
It ended the era of near-zero rates, more than doubled mortgage rates, pushed up cap rates and cut office and apartment values, and made inflation a top political issue.
Think of it like
Like a market where tenants return all at once while new buildings are years away: rents jump until supply catches up.
Facts, rules and data
BLS CPI and Commerce Department PCE data, Fed statements, and studies such as Bernanke and Blanchard's 2023 paper splitting the causes between demand and supply.
Debates and risks
How much came from stimulus and the Fed versus supply shocks and corporate pricing is still argued, as is whether the Fed waited too long.

▸M2: cash, checking, savings and money market funds grew about 40% ahead of The 2021–23 inflation surgeFact, law or data
The connection
Relief checks and Fed bond buying put new money into bank accounts: M2 rose from about $15.4 trillion in February 2020 to about $21.7 trillion by mid-2022. Most of that rise came before prices took off in spring 2021. When spending returned, the extra money met limited supply, and prices rose.
When and why
United States, 2020–2022; M2 grew about 27% in the year to February 2021, the fastest in records back to 1959.
How we know
Fed H.6 money-stock data show the jump; CPI data show inflation rising roughly a year later, as monetarist economists had warned.
Debates and risks
M2 had failed as a signal for decades, and its 2022–23 shrinkage came with falling inflation. How much money growth, versus supply shocks, caused the surge is debated.
▸Jerome Powell, Fed chair 2018–2026 initially called 'transitory' The 2021–23 inflation surgeFact, law or data
The connection
Through most of 2021 Powell said rising prices were 'transitory', the result of reopening bottlenecks. In November 2021 he retired the word, and from March 2022 the Fed raised rates 11 times, to 5.25–5.50%. Critics say the delay let inflation spread from goods into wages and services.
When and why
FOMC meetings and press conferences, 2021–2023; Powell dropped 'transitory' in Senate testimony on November 30, 2021.
How we know
His statements and testimony are on record, and the FOMC's own projections underestimated 2021–22 inflation.
Debates and risks
Whether earlier hikes would have prevented the surge, or only caused a recession without fixing supply shocks, is debated.
▸Markets, prices, supply and demand shocks drove part of The 2021–23 inflation surgeMainstream view
The connection
When the economy reopened, demand for goods jumped while factories, ports and chip makers could not keep up, so prices rose until supply caught up. Russia's 2022 invasion then cut energy and grain supplies. As shipping and supply chains healed in 2023, goods inflation fell sharply.
When and why
Global, 2021–2023; dozens of container ships waited off Los Angeles and Long Beach in late 2021, and chip shortages cost automakers millions of vehicles.
How solid is the link?
The New York Fed's Global Supply Chain Pressure Index peaked in late 2021; Bernanke and Blanchard's 2023 study attributes much early inflation to supply shocks.
Debates and risks
Economists disagree how much was supply versus stimulus-fed demand; both raise prices, so separating them depends on the model used.
▸The 2021–23 inflation surge forced fast hikes in The federal funds rateFact, law or data
The connection
With CPI inflation reaching 9.1% in June 2022, the Fed reversed course. From March 2022 to July 2023 it raised the fed funds target from near zero to 5.25–5.50%, including four three-quarter-point hikes, the fastest tightening since the early 1980s.
When and why
FOMC meetings in Washington, March 2022 to July 2023, under Chair Jerome Powell.
How we know
Published FOMC statements and the New York Fed's daily effective-rate data record each step.
Debates and risks
Critics argue the Fed started too late, having called inflation 'transitory' in 2021; whether hikes or supply recovery did more to cool it is debated.
▸The 2021–23 inflation surge pushed rates to 9.62% on Series I savings bondsFact, law or data
The connection
Because the I bond rate resets from CPI, the inflation surge flowed straight into it: the rate set for May to October 2022 was 9.62% a year, with a 0% fixed part. Savers rushed in, buying nearly $1 billion on a single day in late October 2022. As inflation cooled the rate fell, to 6.89% that November.
When and why
Rate announced in May 2022 by Treasury's Bureau of the Fiscal Service; the buying rush peaked on TreasuryDirect in October 2022.
How we know
TreasuryDirect's published rate history and Treasury sales reports.
Debates and risks
How many buyers kept their I bonds after rates fell; the $10,000 yearly cap kept the boom small relative to the inflation it hedged.
