Yen Tumbles 1% Amid Speculation of Another Intervention Round

The yen has experienced its most significant weekly decline in three months, falling by about 1% against the dollar.

This downward trend is attributed to the diminishing effects of intervention by the U.S. and Japan, leading traders to speculate on another round of official buying to support the currency.

The yen traded near 164 per dollar before July's intervention, but now traders view the 160 level as a potential trigger for more official action.
