The Japanese Yen increased to the highest level from the World War II against the US dollar, as the risk of radiation leaks from crippled nuclear plants in Japan, added to speculation insurers and investors will redeem overseas assets to pay for damages.

The yen gained to 77.48 per dollar at 5:42 p.m. in New York after passing its post-World War II high of 79.75 reached in April 1995, from 80.72 yesterday.

The strongest yen increases speculation that the BOJ will intervene into the market during the period to stabilize.
