The yen climbed to a 10-week peak on May 7, drawing fresh talk of official intervention as it built on earlier gains. The currency's move follows recent support measures and has kept traders focused on key levels.
Japan's currency strengthened markedly in Asia trading on May 6. It advanced as much as 1.8 percent to 155.04 per dollar, its best level since February 24, before easing to around 156.37.
The rally extended into the next session. By May 7 the yen had reached a 10-week high, reviving chatter among traders about possible steps by the Finance Ministry.
Market participants see the 160 level as a likely trigger point for intervention. Recent official actions have already supported the currency and now dominate daily discussions.
