Bloomberg reported late on Tuesday that the ECB will probably gradually wind down its bond purchases before it concludes quantitative easing, rattling global markets and sending bond prices lower.

The utilities and real estate indexes, which tend to outperform when yields contract because sector stocks offer a stable income stream, were down 1.4 percent and 1.9 percent respectively.

Deutsche Bank rose 1 percent after German markets newsletter Platow Brief reported that the German lender was hoping for a settlement of $4-5 billion by end-October with U.S. authorities seeking a fine of up to $14 billion for the mis-selling of mortgage-backed securities.
Tesco rose 7.8 percent, touching its highest level in more than a year after posting first-half results at the top end of expectations. It said it would increase investment to boost profitability over the next three years.
