European shares closed lower on Friday, after St. Louis Fed President James Bullard said the U.S. central bank could taper its $85-billion-a-month bond-buying program in October.
The FTSEurofirst 300 Index closed provisionally 0.2 percent lower at 1,263.0, with European shares pushed down by investors taking profit, although they continued to hover around five-year highs. The U.K. FTSE closed down 0.4 percent, the German Dax closed down 0.2 percent and the French Cac closed up 0.1 percent.
Bullard emphasized in an interview with Bloomberg the role that economic data has played, and will continue to play in Fed decisions
"This was a close decision here in September," he told the network.
Europe stocks started the day in negative territory, bringing an end to the broad rally which started after the Federal Reserve surprised markets by opting to maintain its $85 billion-per-month asset purchases. However, Bullard's comments on Friday backed up the belief that the Fed still plans to taper soon.
In Europe, German voters are preparing to go the polls in Sunday's general elections. The current chancellor, Angela Merkel, is expected to win a third term in office, but the future composition of the governing coalition remains unclear. It is possible that Merkel might have to form an alliance with the rival Social Democrats party (SPD).
