Inflation Surges Again as Iran War and Tariffs Drive Prices Higher, Pressuring Fed Outlook

Inflation Returns as Price Pressures Re-Accelerate

Fresh US data points to a sharp resurgence in inflation, with back-to-back reports showing broad-based price increases that are proving difficult to dismiss as temporary. The renewed heat is landing on consumers already worn down by years of elevated costs and growing frustration that leaders are not prioritizing household finances.

President Donald Trump drew criticism this week after telling reporters he does not consider Americans’ financial strain when negotiating with Iran, saying: “I don’t think about Americans’ financial situation… I think about one thing: We cannot let Iran have a nuclear weapon.”

Like former President Joe Biden, Trump now faces an inflation problem. But the current surge is closely associated with policy-driven shocks unfolding during Trump’s term—namely tariffs and the war with Iran—rather than the pandemic-era disruptions and the Russia-Ukraine war that shaped inflation dynamics earlier in the decade.

CPI Jumps, and Wholesale Inflation Signals More Pain Ahead

The Consumer Price Index (CPI) report released Tuesday showed inflation rising 3.8% year over year, a sharp acceleration from February’s 2.4% annual pace, recorded before the US and Israel began attacking Iran.

The follow-up data was even more alarming. The Producer Price Index (PPI)—a measure of wholesale prices paid by businesses that often foreshadows consumer inflation—hit a 6% annual rate in April, up from 4% in March. On a month-to-month basis, wholesale prices rose 1.4%, which was double economists’ expectations and marked the second-largest monthly jump on record. (The biggest monthly increase occurred in March 2022, three months before consumer inflation peaked.)

Trump argued Tuesday that inflation is “just short-term,” echoing language used in 2021 when the Biden White House characterized rising prices as temporary.

Core Services Inflation Looks “Sticky”

While energy prices are volatile, the April inflation shock is not confined to gasoline or other one-off swings. The war’s immediate impact was severe: it effectively took 20% of the world’s oil supply offline virtually overnight, helping fuel the spike.

However, economists focus heavily on core inflation—measures that strip out volatile categories such as energy—to evaluate whether inflation is becoming embedded. In April, the notable upside surprise in CPI came from services, including rent, health care, car insurance, airfare, hotels, and restaurants.

The report also reflected an unusually large increase in housing costs tied to a data “hangover” from the most recent federal government shutdown. Even adjusting for that distortion, services inflation remained persistent. Core services, excluding energy and housing, rose 3.3% year over year and increased 0.5% from March to April.

Heather Long, chief economist at Navy Federal Credit Union, said it is harder to overlook sustained services inflation than a jump in goods prices driven by fuel. She questioned how policymakers can maintain an optimistic narrative if services inflation continues to print at 0.5% monthly increases.

Austan Goolsbee, president of the Federal Reserve Bank of Chicago, told NPR that the pressure in services suggests the economy may be “overheating,” adding that the Fed has to consider how to “break the chain of escalating inflation.”

Markets Reprice the Fed: Rate Cuts Fade, Hike Odds Rise

The inflation rebound is quickly reshaping market expectations. Wall Street’s outlook for a Fed rate cut this year has largely evaporated. On Wednesday, bond traders pushed up US Treasury yields, reflecting longer-term inflation concerns and the possibility the central bank may need to tighten further.

Investors now assign more than a 30% chance of a rate hike by year-end.

Tariffs Add Another Layer of Inflation Pressure

The economic drag from the Iran war is also colliding with Trump’s other defining policy choice: tariffs, widely viewed as a tax on US businesses.

During Trump’s second term, the US government has collected more than $340 billion in tariff revenue. But businesses have had to absorb part of those added costs, reducing their financial buffer just as energy prices surge due to the conflict. As a result, at least some of the combined cost burden is likely to be passed through to consumers.

Consumer Sentiment Sours and Approval Slides

Polling suggests consumers are already feeling the squeeze. A CNN/SSRS poll released Tuesday found 77% of Americans—including a majority of Republicans—believe Trump’s policies have raised the cost of living in their community. Another 75% said the Iran war has harmed their personal finances.

Trump’s approval rating on the economy fell to a career-low 30%, according to the poll. CNN’s Stephen Collinson noted that dissatisfaction on economic issues in the 70% range indicates anger among Republicans as well as Democrats and independents, turning affordability into what he called an “incumbent’s curse.”

Coinasity's Take

The latest CPI and PPI prints highlight a shift from energy-driven volatility to sticky services inflation, a mix that tends to keep interest rates higher for longer. With tariff-related costs already embedded in supply chains and the Iran conflict disrupting energy markets, the risk of sustained inflation increases—conditions that can tighten financial conditions across markets, including crypto, as liquidity expectations adjust alongside Treasury yields and shifting Fed odds.
