Here is the inflation analysis for March 2026 — presented in a single chart

Inflation increased in March due to the Iran conflict raising gasoline and other costs for consumers.

The consumer price index, a vital inflation indicator, surged 3.3% in March from the previous year, as reported by the U.S. Bureau of Labor Statistics on Friday. That’s up from 2.4% in February.

The release of March data marks the first CPI report since the onset of the Iran conflict on Feb. 28, highlighting the financial consequences for consumers during the initial month of hostilities in the Middle East.

While the U.S. and Iran reached a two-week ceasefire late Tuesday, economists indicated that the inflationary consequences of the conflict will likely take several weeks or months to resolve — and that a drawn-out conflict could elevate consumer prices across categories, including food, airfare, and manufactured goods.

“Inflation is a concern and it’s only going to intensify,” stated Mark Zandi, chief economist at Moody’s. “Clearly, the situation in Iran is causing significant harm.”

“We were tentatively hopeful about inflation at the start of this year,” with pressures such as those from tariffs easing, said Thomas Ryan, a North America economist at Capital Economics.

“Essentially, we’re in a wait-and-see mode right now, just to assess the impact of the energy price shock,” Ryan noted. “If it proves to be lasting, we become increasingly worried about leakage” into other consumer spending areas, he added.

The inflationary spike due to the Iran conflict complicates the Federal Reserve’s task of setting interest rate policy.

During the March meeting, central bank officials indicated they anticipate cutting interest rates once this year, although some mentioned that it may become necessary to increase borrowing costs if the Iran conflict results in sustained inflationary pressures.

Fed officials also expressed the need to stay “nimble” as they assessed the war’s impact on inflation, which persists above the central bank’s 2% target.

“Inflation is significantly above acceptable levels for both consumers and the Federal Reserve — and that situation won’t improve, at least in the coming months,” Zandi mentioned.

The recent surge in energy prices is largely attributed to oil.

Iran has effectively restricted maritime traffic through the Strait of Hormuz, a crucial route for transporting approximately one-fifth of the global oil supply. The blockade appears to remain largely intact even after the ceasefire, according to reports.

Oil prices — as tracked by Brent crude oil, a global pricing standard — surged to $118 per barrel by March’s conclusion, up from around $70 per barrel prior to the onset of conflict. Prices have since trended down, yet remain high at approximately $96 as of Friday.

“There’s optimism now, as we have a two-week ceasefire and we hope it lasts,” stated Joe Seydl, a senior markets economist at J.P. Morgan Private Bank. “Otherwise, we may be facing the most significant oil supply shock in the post-World War II era.”

Products made from oil — including gasoline, diesel, and jet fuel — have also seen sharp increases.

Retail gasoline prices jumped 18.9% over the past year, according to the CPI data.

Consumers were paying an average of $4.12 per gallon as of Monday, according to the U.S. Energy Information Administration’s most recent weekly statistics — a rise from around $2.94 prior to the conflict.

This rise above $4 per gallon marks the first occasion the national average price has exceeded that threshold since 2022, when Russia’s invasion of Ukraine caused prices to spike, as demonstrated by EIA data.

Concurrently, rising oil prices are affecting other sectors of household budgeting as well.

For instance, airlines are increasing ticket prices,raising baggage fees, introducing fuel surcharges and reducing flight schedules to mitigate the impact of the Iran conflict — actions that collectively heighten costs for travelers.

Airlines are taking these steps to counteract rising jet fuel expenses, which constitute one of their biggest operational costs.

Airfares increased by 14.9% over the past year, according to CPI figures.

The increase is particularly striking for international travel: For instance, an average round-trip economy fare from the U.S. to Rome rose to $1,165 as of March 30, up from $846 on Feb. 23, according to the latest weekly flight statistics compiled by Kayak, a travel search engine. A round-trip ticket to Hong Kong climbed to $1,403 from $1,042 during the same time frame.

If jet fuel prices continue at their current levels for a full year, airlines would need to raise ticket prices by roughly $50 for each one-way fare, or about 17%, analysts from Deutsche Bank mentioned in a report on Tuesday.

Food prices are another segment that might experience upward pressure due to escalating oil prices, economists noted.

For instance, a rise in diesel costs influences the transportation expenses tied to delivering food to grocery stores. Additionally, fertilizer is a key export through the Strait of Hormuz, posing a threat to increase prices for farmers and consumers.

Food prices have risen by 2.7% over the last year, per CPI figures. Specific categories like beef and coffee have witnessed even steeper price hikes due to unique situations affecting supply.

Americans may also see heightened costs for items purchased through e-commerce platforms. Amazon plans to implement a 3.5% fuel and logistics surcharge for third-party sellers in the U.S. and Canada starting April 17. Other shipping companies like United Parcel Service and FedEx have also enforced increased fuel surcharges since the beginning of the Iran conflict.

Some inflationary pressures from energy costs may take months to impact supply chains and reach consumers, according to Ryan from Capital Economics. The effect “could be quite widespread,” he stated.

Ultimately, the full inflationary repercussions will hinge on the circumstances of the conflict.

If hostilities cease by late April and the Strait of Hormuz begins to reopen, CPI inflation would probably reduce “fairly rapidly,” according to Ryan. He predicts it will peak around 4% and decline to 3% by the end of 2026.

Conversely, an extended conflict would sustain high inflation and increases the likelihood of broader pass-through to goods and services, he cautioned.

Even if oil tankers resume passage through the Strait of Hormuz, normalcy may take time to restore, economists warn.

For instance, damage from attacks on energy facilities in the Middle East will require time for repairs, they noted.

Seydl, from J.P. Morgan Private Bank, used the term “up like a rocket and down like a feather” to characterize the anticipated price trends, indicating that prices for gasoline and other household budgeting areas tend to rise swiftly following a shock, but decrease slowly.

There’s also likely to be a persistent “risk premium” on oil prices once the conflict concludes, Seydl pointed out. “Investors are aware that this scenario could happen again,” he remarked.

Increased ancillary airline costs, such as baggage fees, may also prove to be long-lasting, particularly if demand stays robust, analysts suggested.
