[WASHINGTON] US consumer prices recorded their biggest increase in more than three years in April as gasoline and rents rose, pointing to a steady inflation build-up that could give the Federal Reserve ammunition to raise interest rates later this year.
The Labour Department said on Tuesday its Consumer Price Index increased 0.4 per cent last month, the largest gain since February 2013, after rising 0.1 per cent in March. That took the year-on-year increase in the CPI to 1.1 per cent from 0.9 per cent in March.
There were also increases in medical care and food prices. Economists polled by Reuters had forecast the CPI gaining 0.3 per cent last month and advancing 1.1 per cent from a year ago.
The so-called core CPI, which strips out food and energy costs, rose 0.2 per cent after climbing 0.1 per cent in March. In the 12 months through April, the core CPI increased 2.1 per cent after increasing 2.2 per cent in March.
The Fed has a 2 per cent inflation target and tracks an inflation measure which is currently at 1.6 per cent.
The rise in prices in April is likely to be welcomed by Fed officials who last month softened their language on inflation at the end of a regular meeting, noting that it continued to run below target because of "earlier declines in energy prices and falling prices of non-energy imports."
Financial markets do not expect the Fed to hike rates again before September, given sluggish growth at the beginning of the year. The US central bank lifted its benchmark overnight interest rate in December for the first time in nearly a decade and policymakers have forecast two more rate hikes this year.
While data on April retail sales suggest economic growth regained steam early in the second quarter, a slowdown in payrolls gains last month and a recent spike in new applications for unemployment benefits have raised some concerns about the labour market's health.
In April, gasoline prices jumped 8.1 per cent, the largest gain since August 2012, adding to March's 2.2 per cent increase. Food prices rose 0.2 per cent after falling 0.2 per cent in March.
The core CPI was lifted by housing and medical costs, as well as transportation services. Owners' equivalent rent of primary residence rose 0.3 per cent after increasing 0.2 per cent in March.
Medical care costs picked up, rising 0.3 per cent after gaining 0.1 per cent in March. Prescription drugs shot up 0.7 per cent and the cost of hospital services increased 0.3 per cent.
But apparel prices fell for a second straight month as did the cost of used cars and trucks. Prices for new motor vehicles fell 0.3 per cent.
