The yen has regained some of its recent losses against the dollar, but the upturn could soon run out of steam.

Having weakened to 135.02 to the dollar in overseas trading on Feb. 27, the yen soon rebounded and is now hovering around 132.

The recent resurgence in Tokyo stock prices has provided a floor for the falling yen and the 135 yen level has, for now, become a resistance line for the dollar.
