US Inflation Quickens to 9.1%, Amping Up Fed Pressure to Go Big

US inflation accelerated in June by more than forecast, underscoring relentless price pressures that will keep the Federal Reserve on track for another big interest-rate hike later this month.

The consumer price index rose 9.1% from a year earlier in a broad-based advance, the largest gain since the end of 1981, Labor Department data showed Wednesday. The widely followed inflation gauge increased 1.3% from a month earlier, the most since 2005, reflecting higher gasoline, shelter and food costs.

Economists projected a 1.1% rise from May and an 8.8% year-over-year increase, based on the Bloomberg survey medians.
