January Inflation Data Offers a Baseline as Oil Shock Raises New Risks

On the morning of March 13, as oil traders watched crude prices vault past $100 a barrel, a quieter data release in Washington delivered a different kind of warning about the U.S. economy.

The Commerce Department’s Bureau of Economic Analysis reported that its personal consumption expenditures (PCE) price index — the Federal Reserve’s preferred inflation gauge — rose 0.3% in January from the prior month and 2.8% from a year earlier. Stripped of food and energy, so-called core PCE increased 0.4% in January and 3.1% over 12 months, the fastest annual pace in nearly two years.

Those figures predate the Iran war and the oil shock that followed. But they show that the long, uneven retreat from the pandemic-era inflation spike had already stalled before missiles flew and tankers were threatened in the Strait of Hormuz.

The January report is likely to serve as a crucial baseline for the Federal Reserve and financial markets as they assess how much of any renewed inflation will be driven by the conflict and how much reflects underlying pressures at home. It also complicates political calls for rapid interest-rate cuts in the face of higher fuel costs and slowing growth.

“Inflation remains somewhat elevated, and we are strongly committed to returning it to our 2% objective,” Fed Chair Jerome Powell said after the central bank’s Jan. 27–28 policy meeting, days before the Iran war began. He said decisions would be made “meeting by meeting,” guided by incoming data.

The January PCE figures are now a central part of that data.

A last clean read on inflation

Because the numbers cover January, they capture consumer prices before the Feb. 28 start of U.S. and Israeli strikes on Iranian targets and the ensuing disruption in the Persian Gulf. That timing makes the report one of the last clear snapshots of domestic inflation pressures before the war-driven energy shock hit.

In its March 13 release, BEA said personal income increased 0.4% in January, or $113.8 billion at a monthly rate. Disposable personal income, which reflects taxes and government transfers, climbed 0.9%, helped by the annual cost-of-living adjustment for Social Security benefits and higher dividend income. Personal consumption expenditures, the broadest measure of household spending, rose 0.4% in nominal terms.

After adjusting for inflation, real consumer spending inched up 0.1%. The personal saving rate, which measures saving as a share of disposable income, rose to 4.5% from 3.6% in December, suggesting some households used their income gains to rebuild financial cushions rather than increase purchases.

The composition of spending also shifted. Outlays on services, from housing and health care to travel and entertainment, increased by more than $100 billion at a monthly rate. Spending on goods fell by about $25 billion, continuing a rotation away from the physical products that surged in demand earlier in the pandemic.

On the inflation side, the overall PCE price index edged down slightly on a year-over-year basis, from 2.9% in December to 2.8% in January. But the core index — which Fed officials closely watch as a guide to underlying trends — rose to 3.1% from 3.0%, the second consecutive month of 0.4% monthly increases after a stretch of softer readings late last year.

That pattern points less to a fresh burst of inflation than to what many economists describe as sticky prices, particularly in labor-intensive services.

“Progress on inflation has slowed,” Powell told reporters in January. “We are not yet confident that inflation is moving sustainably down to 2 percent.”

Oil shock on top of sticky core

Within weeks of those remarks, the economic backdrop changed dramatically.

Following the late-February strikes on Iran and subsequent threats and attacks around the Strait of Hormuz — a transit route for roughly a fifth of globally traded oil — benchmark crude prices soared. Brent crude topped $100 a barrel and at points traded near $118, levels last seen after Russia’s 2022 invasion of Ukraine. West Texas Intermediate, the U.S. benchmark, briefly rose above $110.

Gasoline prices jumped in response. By mid-March, the average price at U.S. pumps hovered around $3.80 to $3.90 a gallon, according to federal data and private price trackers, with some Western states, including California, above $5.

Economists at major banks and international institutions have warned the shock has the potential to both lift inflation and weigh on growth — a combination often described as stagflationary. Higher fuel costs feed directly into household budgets and raise transportation and production costs for businesses, which can then pass those increases along to consumers.

What January’s PCE data suggest is that this new energy shock is arriving on top of, rather than instead of, an existing inflation challenge.

Core PCE had already drifted higher over several months, rising from roughly 2.9% year-over-year in the fall to 3.0% in December and 3.1% in January. Monthly core readings also firmed, from 0.2% in November to 0.4% in December and January. Headline inflation, which includes energy, had slowed but remained above the Fed’s target.

Those levels are far below the 7% peaks seen in 2022, but still high enough to make central bankers wary of easing policy too quickly.

Fed holds line under new pressure

By the time Fed officials met again on March 17–18, the Iran war and oil price spike were dominating headlines. The central bank left its benchmark federal funds rate unchanged in a range of 3.5% to 3.75% and updated its projections to show slightly higher expected inflation for the year, including a higher median forecast for core PCE.

In his March news conference, Powell acknowledged the new risks from the conflict and rising energy costs but emphasized that the underlying inflation trend had already turned less favorable before the war.

“Inflation had been running above our goal and progress had slowed even before recent developments in the Middle East,” he said. The Fed, he added, would be “carefully assessing” whether the oil shock proved temporary or more persistent.

That stance has put the central bank at odds with some political leaders who are urging faster cuts to borrowing costs as households confront higher bills.

President Donald Trump has repeatedly criticized the Fed for not lowering rates more quickly, arguing that high interest costs hurt economic growth and raise the government’s own debt burden. He has also publicly complained about Powell’s leadership.

At the same time, a Justice Department investigation into Powell’s conduct has raised concerns among former officials and economists about the potential politicization of monetary policy. Janet Yellen, the former Fed chair and Treasury secretary, warned recently that pressuring the central bank to slash rates to ease fiscal strains risked undermining its credibility, likening such a path to “the road to a banana republic.”

The Fed, for its part, maintains that its decisions are guided by its dual mandate from Congress: maximum employment and stable prices.

Markets rethink rate-cut bets

Financial markets have been forced to reassess expectations that, only a few months ago, were leaning toward a relatively smooth “soft landing” — slower but steady growth, cooling inflation and rate cuts later this year.

January’s PCE report itself did not shock investors. The core and headline figures broadly matched economists’ forecasts, and the initial reaction in Treasury yields and stock indices was limited. But the data reinforced a message that rate cuts were conditional on continued progress toward the 2% inflation goal.

The subsequent oil spike and the Fed’s more cautious tone have led traders to scale back bets on how much easing will occur in 2026. Futures markets that once priced in two or three quarter-point cuts by year-end now imply a slower and more uncertain path, particularly if oil prices remain elevated.

Mortgage rates have edged higher in recent weeks, reflecting both shifting expectations for Fed policy and volatility in bond markets. That adds to pressure on prospective homebuyers already squeezed by high prices.

Equity strategists say investors are adjusting to the idea that policy rates may stay “higher for longer” than previously assumed, even as growth slows.

Households feel the squeeze

Beyond markets and policy debates, the combination of stubborn core inflation and more expensive fuel lands most heavily on household budgets.

Low- and moderate-income families, who spend a larger share of their income on necessities like gasoline and food, are especially vulnerable to energy price shocks. The modest rise in the saving rate in January suggests some households were building financial buffers even before oil spiked, but many still have limited reserves after years of elevated prices.

Some groups have received a temporary lift. Social Security beneficiaries saw their payments rise in January due to the annual cost-of-living adjustment, which contributed to the jump in transfer income in the BEA report. Investors also benefited from higher dividend income.

Those supports, however, may be eroded over time if inflation remains above target.

For the Fed, the January PCE data underscore the difficulty of the choices ahead. With inflation not yet fully subdued and a new war-driven energy shock rippling through the economy, policymakers must decide how much to lean against rising prices and how much to shield growth and employment. The seemingly routine numbers published on March 13 — a few tenths of a percent on a government spreadsheet — are likely to shape that debate for months to come.
