July 12 (Reuters) - 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 JPY=EBS , while the euro EURJPY=EBS was down 0.3% at 172.04 yen.
It was not immediately clear what was behind the latest move. (([email protected]; +442031978531; Twitter: https://twitter.com/a_coops1;))
