Brazil's central bank on Wednesday raised its key interest rate to 13.25 percent, as Latin America's largest economy fights to keep a lid on inflation despite a slowing economy.
The increase, the fifth consecutive one, was largely anticipated by analysts polled by the central bank.
"In assessing the macroeconomic scenario and the outlook for inflation, the Copom (the bank's monetary policy committee) decided unanimously to raise the rate by 0.5 percentage points, to 13.25 percent," it said in a statement.
The hike puts rates at their highest level since January 2009.
Inflation in 2014 reached 6.41 percent, just below the government's maximum tolerated rate of 6.5 percent. The official annual target rate, however, is 4.5 percent.
President Dilma Rousseff, who was re-elected in October, has responded by paring back the budget while promising to protect social programs for the working class.
After several years of booming growth, Brazil's economy has been slowing in recent years and growth in 2014 was a very muted 0.1 percent.
