Iran Conflict Triggers Inflation Spike; US CPI Hits 3.3% in March

US inflation accelerated sharply in March, with the Consumer Price Index (CPI) rising to 3.3% year-over-year, up from 2.4% in February. The spike is primarily attributed to the onset of the conflict in Iran, which began on February 28 and has caused immediate disruptions to global energy markets. The primary driver is the blockade of the Strait of Hormuz, a critical waterway for approximately 20% of the world's oil supply. This supply shock pushed Brent crude prices to a peak of $118 per barrel in March, compared to $70 prior to the conflict. While prices have moderated to roughly $96 following a recent two-week ceasefire, economists warn that the inflationary pressure remains systemic. The impact is most visible in retail gasoline, which surged 18.9% over the past year to an average of $4.12 per gallon. Additionally, airfares have climbed 14.9% as airlines implement fuel surcharges and cut schedules to offset rising jet fuel costs. For instance, round-trip economy fares from the U.S. to Rome jumped from $846 in February to $1,165 by late March. This inflationary surge places the Federal Reserve in a difficult position. While officials previously signaled a potential rate cut this year, the persistence of inflation above the 2% target may force the central bank to remain nimble, with some officials suggesting that borrowing costs could actually rise if the conflict prolongs.
