US Q1 GDP grew 2.0%, and March core PCE hit 3.2%, a new 3-year high

The U.S. Department of Commerce’s Bureau of Economic Analysis (BEA) simultaneously released on April 30 its 2026 Q1 GDP forecast report and the March Personal Consumption Expenditures (PCE) price index. Q1 GDP’s annualized growth rate was only 2.0%, below market expectations of 2.2-2.3%, but it clearly rebounded from Q4 2025’s 0.5%. March core PCE rose 3.2% year over year and 0.3% month over month, reaching a 3-year high. The Iran war has lifted energy prices as the main cause of the re-acceleration of inflation, forcing the Federal Reserve into a more difficult position.

Q1 GDP 2.0% below expectations: investment, exports, and government spending all help, while consumption slows

The BEA’s Q1 advance estimate shows that real GDP in 2026 Q1 grew at an annualized rate of 2.0%, sharply accelerating from Q4 2025’s 0.5% but still falling short of market expectations of 2.2-2.3%. Growth momentum came mainly from four positive contributors: investment (equipment, intellectual property, and inventories), exports (driven by computer and peripheral equipment), consumer spending (such as healthcare services), and government spending (a surge in federal non-defense spending); the negative contributor was expanding imports in step.

“Real final sales to private domestic purchasers” grew 2.5%, accelerating from Q4’s 1.8%, indicating that underlying private demand still has resilience. But Q1 GDP’s price index annualized at 3.6%, and the PCE price index annualized at 4.5% (core 4.3%), reflecting inflationary pressure rising sharply—this is not just a growth story.

March core PCE up 3.2% year over year and 0.3% month over month: the Iran war lifts energy, reaching a 3-year high

The March month-on-month data show that total PCE’s year-over-year growth jumped to 3.5%, while core PCE (excluding food and energy) accelerated from 3.0% in February to 3.2% and rose 0.3% month over month. This is the highest level of core PCE inflation since 2023, reflecting that the Iran conflict that began at the end of February has systematically transmitted the shock in global energy prices to the consumer side.

Even though core PCE excludes the direct impact of energy, higher energy prices spread to the final pricing of non-energy goods and services through three channels: transportation, raw materials, and production costs—driving “sticky” inflation higher. The event that Brent crude briefly broke above $114 on 4/29 and WTI rose 3.3% directly matches the Q1 PCE annualized figure of 4.5%.

Fed’s situation: growth falls short, inflation accelerates, and on 4/29 it chose to hold steady

The release of these GDP and PCE data coincided with the Federal Reserve’s 4/29 policy decision to hold rates steady and maintain 3.5-3.75% just one day earlier. The rationale for the Fed’s “no rate cut” on 4/29 was further reinforced by the new data: the upward trend in inflation has not stopped, and growth is below expectations but has not slipped into contraction. As a result, the probability of a June rate cut that the market had originally priced in has fallen markedly.

From the perspective of the Fed’s dual mandate, the current situation features two forces in direct collision: “growth is below expectations → should cut rates” versus “inflation is above target and accelerating → should raise rates or at least hold.” The 4-vote split within the Fed on 4/29 (the last decision during Powell’s tenure) already showed that debate over the policy path is heating up. The next key point to watch is the April employment report on May 9. If the unemployment rate climbs back to 4.5% or above, the dovish case will strengthen significantly; if it stays around 4.2%, the Fed will likely continue to hold off until the July meeting before taking policy action.
