US Q1 PCE YoY Remains Flat at 2.8%, Geopolitics Fuel Concerns of Inflation Rebound

Core Overview According to the latest data, the US first quarter (February 2026) Personal Consumption Expenditures (PCE) price index year-over-year growth rate reported at 2.8%, completely flat compared to the previous observation (January) of 2.8%, and in line with the general expectations of market analysts. Against the backdrop of a stalled disinflationary process over the past few months, this data highlights that US price pressures remain highly sticky, with the overall trend still significantly above the 2% policy target set by the Federal Reserve (Fed).

Key Components Observing the detailed performance, although the headline year-over-year rate did not surge, the February PCE month-over-month rate accelerated to 0.4%, higher than January's 0.3%, marking the largest monthly increase in nearly a year. In addition, excluding volatile food and energy, the core PCE price index year-over-year rate—the Fed's preferred inflation gauge—edged down slightly from the previous 3.1% to 3.0%, but its month-over-month rate also remained elevated at 0.4%. Among them, commodity prices turned positive, driven by auto parts and gasoline, surging 0.7% month-over-month, becoming the primary momentum pushing up overall expenditures.

In-depth Attribution The core driver behind the failure of inflation to cool further primarily stems from the rapid deterioration of recent geopolitical conditions. Reuters and market analyses point out that the recent US-Iran conflict has led to a surge in global crude oil prices, with the US national average retail gasoline price breaking above $4 per gallon for the first time in over three years. Meanwhile, Fed officials also warned in internal meetings that "if the Middle East conflict continues to prolong, rising energy and logistics costs are highly likely to pass through to core inflation," further dampening the market's optimistic expectations for a steady decline in prices in the short term.

Outlook and Risks Looking ahead, in the short term (1-2 months), the market needs to pay close attention to the subsequent developments of geopolitical conflicts and global supply chains. Although there is news of a temporary ceasefire, disruptions in key shipping hubs such as the Strait of Hormuz may still cause more pronounced rebounds in the March and April inflation data. In the medium term (3-6 months), if commodity prices remain elevated and inflation continues to miss the target, the probability of a Fed rate cut this year will be significantly diminished; investors should be wary of the potential correction risks that a "Higher for Longer" interest rate environment poses to stock market valuations, corporate profits, and borrowing costs in the real economy.
