SAO PAULO Oct 19 (Reuters) - Brazil's central bank offered to buy dollars on the spot foreign exchange market on Monday as part of an ongoing effort to boost international reserves and soak up greenbacks pouring into the economy.

The real BRBY was trading 0.23 percent weaker at 1.711 per U.S. dollar shortly after the central bank's announcement. (Reporting by Silvio Cascione; Writing by Luciana Lopez; Editing by James Dalgleish)
