Brazil's central bank calls auction to buy dollars

SAO PAULO, July 6 (Reuters) - Brazil's central bank offered to buy U.S. dollars on the spot foreign exchange market on Monday, seeking to soak up a flood of greenbacks pouring into the country.

Brazil's currency, the real (BRBY), was trading 0.87 percent weaker at 1.970 per U.S. dollar shortly just before the bank's announcement.

The bank has bought dollars every session since May 8. Last Wednesday it said it had bought $1.69 billion on the spot market last month through June 26. (Reporting by Jose de Castro; Writing by Peter Murphy; Editing by James Dalgleish)
