Inflation accelerated sharply in March 2026, with the Consumer Price Index rising 3.3% over the prior 12 months. That is a significant jump from the 2.4% rate recorded in both January and February.
Monthly prices climbed 0.9% in March, the largest single-month gain in nearly four years. Energy prices drove the increase. The energy index surged 10.9% in March, with gasoline prices jumping 21.2%, the largest monthly increase since 1967.
US-led military action against Iran disrupted global oil supply and sent prices higher. The energy spike accounted for nearly three-quarters of the overall monthly price increase.
Core inflation, which strips out food and energy, was more contained. It rose 0.2% for the month and 2.6% over the year.
The Federal Reserve held interest rates steady at 3.5% to 3.75% at its March meeting. Officials revised the 2026 inflation forecast upward and signaled that rate cuts for the year are now less certain. That uncertainty affects anyone with variable-rate debt or those waiting for mortgage rates to fall.
The next inflation report is due May 12, 2026. Financial advisors suggest monitoring the report closely and considering inflation-protected investments such as Series I bonds, which the Treasury Department has set at a 4.26% rate through October 2026.
Geopolitical tensions in the Middle East are also affecting global markets beyond the United States. Countries like India are seeing impacts on transportation costs, manufacturing, and consumer spending as oil prices remain elevated.
