CHINA EXPLAINS: Officials from China's central bank defended recent moves to loosen the government's grip on its currency, saying that the yuan will eventually rebound from its recent fall. There is "no basis for persistent and substantial devaluation," said a deputy central bank governor, Zhang Xiaohui. The yuan is close to "market levels" after two days of sharp drops, Zhang said.

Beijing's surprise devaluation of its currency shook markets around the world this week, upending stocks, commodities and currencies.
