Brazil's currency weakened on Friday after the central bank bought dollars on the foreign exchange market. Higher interest rates in the world's biggest economy are potentially damaging for riskier assets in emerging countries like Brazil.
Meanwhile, the Brazilian real ended 0.62 percent weaker at 2.264 per dollar after the central bank bought the greenback on the spot market for the 13th time this month.
"The central bank stepped in today and drained dollars from the market," said Hideaki Iha, an analyst with Souza Barros brokerage.
The central bank bought only a small amount of dollars this time, traders said, but that was enough to weaken the real as liquidity was low in the last session of the week.
