Yen Is Weakning Against The US Dollar

Yen is trading at 117.20 against the US dollar after showing considerable strength in the month of August when subprime mortgage mess unfolded in the US and yen carry trade unwinding started. It seems at around 113 levels, lot of carry trade happened as japanese central bank doesn't increased it's benchmark interest rate and japanese as well as oversees investors/hedge funds/PE funds still wanting to have a pie of cheap funds available in yen currency, have them invested in riskier yet high yield assets of emerging economies lke India, China, HongKong, Taiwan, Russia. This is causing tremendous price rises in these assets and thus is a cause of concern in the short term.
