US inflation hit 3% for the first time since January last month, but remained milder than many analysts had expected.
The figure was for an increase in consumer prices the year to September, up from 2.9% in the prior month, the Labor Department said. Analysts had forecast a 3.1% jump.
The report is the first official piece of economic data the US government has published since shutting down earlier this month.
It comes days before the US central bank is due to vote on its next cut to interest rates and bolstered bets that policymakers would decide to lower borrowing costs again.
