Yen Bounces, Traders Wary of more Japan Intervention

FOREX - TOKYO. The yen jumped against the dollar on Friday, with traders on high alert for signs of fresh intervention by authorities, after a surge in the Japanese currency on Thursday that was likely the result of official buying.

The dollar fell as much as 1% to a one-month low of 157.30 yen, and was last at 158.1 yen. The euro was last down 0.3% at 172.04 yen.
