Yen rises amid speculation of more intervention after U.S. support

The yen surged amid speculation of renewed intervention by Japanese authorities and U.S. support, following coordinated market action last week. Traders and analysts noted signs of intervention, with officials from Japan and the U.S. collaborating to stabilize the yen, which had previously weakened to near 1986 lows. The intervention reversed months of losses in two days, though concerns remain about long-term effectiveness.
