Singapore shares closed 0.42 percent lower on Thursday, as investors have become wary of the uncertainty over whether highly indebted Spain will seek a bailout to ease its fiscal strains, as well as global growth slowdown which prompted central banks into action. Investors are waiting for Spain's bond auctions later Thursday. Madrid will seek to raise up to 4.5 billion euro in three-year and 10-year bonds. Meanwhile, Germany's ruling party proposed only limited bank supervisory power for the European Central Bank on Wednesday, highlighting the differences over the speed and shape of oversight reforms and raising worries about the European policymakers' long-term debt-crisis management ability. Singapore's benchmark Straits Times Index fell 13.02 points, or 0.42 percent, to close at 3,062.61.
