Yuan's sharp drop puts investors on alert for reversal of rising trend

The yuan has recently been something of a safe haven among emerging market currencies, yet market players have learned from a bloody lesson over the past week that it is no longer an easy, one-way bet.
A sharp fall against the US dollar both onshore and offshore made the yuan the worst performing currency within emerging Asia this month.
The drop offshore - the most since October last year - caused a massive short squeeze. Many investors were forced to buy back contracts at prices higher than what they cost to close out their short positions.
The onshore rate yesterday capped two weeks of losses by falling 0.46 per cent, the most since November 1, 2010. It closed at 6.1266 per dollar in Shanghai, according to China Foreign Exchange Trade System prices reported by Bloomberg.
Meanwhile, the offshore rate shed as much as 1 per cent in the past fortnight.
The correction has shocked the market as the yuan had been deemed the bright spot in the Asian currency market, given its ultra-low volatility and appreciation trend against the dollar.
