NOBODY talks about “decoupling” any more. Instead, emerging economies are sinking alongside developed ones. In 2008 emerging stockmarkets fell by more than those in the rich world, and financial woes forced countries such as Hungary, Latvia and Pakistan to go cap in hand to the IMF. Taiwan’s exports have plunged by 42% over the past year, and South Korea’s by 17%; even China’s have shrunk. Singapore’s GDP fell by an annualised 12.5% in the fourth quarter of 2008, its biggest drop on record. Is this the end of the emerging-market boom?
