Yen Intervention Fades as Fundamentals Take Hold

The coordinated intervention by Japan and the US to prop up the yen one month ago appears to have had a short-lived effect, as strategists say it didn't address the underlying issues driving its decline.

In late August, the two countries joined forces to boost the yen, which was trading at a four-decade low of around 164 per dollar. The intervention succeeded in slowing the currency's short-term slide, and the yen briefly rose to 155.23 against the US dollar before reversing course.

However, this temporary gain proved unsustainable, with the yen now approaching 160 against the dollar again.
