Yen's Slide to Weekly Loss Sparks Bets for Another Intervention

The Japanese yen has experienced its biggest weekly loss in three months as the effects of recent intervention efforts have begun to wear off. The currency, which was trading near 164 per dollar before July's intervention, is now down about 1% this week to 159.43 per dollar.

Traders are speculating that another round of official buying may be necessary to stabilize the yen, with many viewing the 160 level as a potential trigger for fresh action.

The yen has surrendered roughly half of the gains sparked by intervention in late July and early August, leaving many wondering if more drastic measures will be needed to stem the decline.
