US inflation hit 2.7% in March, with rising food and petrol prices pushing the rate up from 2.3% in February.
Month-on-month prices were up 0.5% and the country has now experienced nine consecutive months of rises in the cost of living.
Petrol and food prices accounted for almost three quarters of the annual increase, and the cost of petrol alone has now risen 14.4% over the last three months.
Without food and energy, inflation would have been measured at 1.2% for the past 12 months, according to the US Labor Department.
The Dow Jones was up 0.24% at 12,315.23 in early trading, with the Federal Reserve also reporting industrial production rose 0.8% in March.
Earlier today, the European Union's Eurostat agency revealed CPI inflation throughout the eurozone hit 2.7% in March, up from 2.4% in February.
A record monthly increase sent the annual rate to a 29-month high, strengthening expectations the European Central Bank will tighten monetary policy further this year.
Meanwhile, CPI inflation in the UK dipped to 4% last month, down from the 28-month high of 4.4% in February.
