What was the year-on-year change in the U.S. Consumer Price Index (CPI) for April, and how does it compare to the previous month?

The CPI advanced 3.8% in the 12 months through April, marking the largest year-on-year increase since May 2023 and up from a 3.3% rise in March.

What primary external factor drove the recent surge in U.S. consumer prices, and how was it reflected in the CPI components?

Oil prices shot above $100 a barrel in March following U.S. and Israel strikes against Iran, leading to higher gasoline, diesel, and jet fuel prices — a direct driver of the CPI’s 0.6% monthly increase in April after a 0.9% surge in March.
