(Bloomberg) -- Wednesday’s respite from a European stocks selloff is proving short-lived.

The region’s shares are falling for the sixth time in seven days as an oil decline deepened, while concerns over monetary policy grew as central banks in Japan and the U.S. kept their policies unchanged. At the same time, worries about the potential exit of the U.K. from the European Union are intensifying a week before the referendum.

Amid a broad selloff, the Stoxx Europe 600 Index lost 1.1 percent at 8:15 a.m. in London, heading for its lowest level since February. More than 555 of its companies declined, with banks falling the most. UBS Group AG fell 1.4 percent, and Credit Suisse Group AG dropped 2.3 percent after the Swiss National Bank said the lenders need to take further measures to meet Switzerland’s new capital requirements. Lenders of Spain, Portugal and Italy declined the most.

Among stocks moving on corporate news, Volkswagen AG lost 1.2 percent as its European market share contracted the most since December and is at a five-year low. Randgold Resources Ltd. advanced 3.8 percent, the most among Stoxx 600 companies, as the precious metal it mines climbed for a seventh day to its highest price since August 2014.
