Yen suddenly jumps, markets on alert for intervention

SINGAPORE, May 4 (Reuters) – The yen suddenly jumped against the dollar in Asia trade on Monday, with ​traders on alert for another ‌bout of intervention after Tokyo likely stepped into the market to shore up the Japanese currency last week.

The dollar was down ‌0.54% ​at 156.22 yen, having ⁠fallen nearly 0.9% ⁠to a low of 155.69 at one point in choppy trade. Trading was thinned with markets in Japan closed ​for a holiday.

Investors were wary of further intervention from Japanese authorities, ⁠after central bank ⁠data on Friday showed Tokyo ​may have spent as much as 5.48 ​trillion yen ($35 billion) bolstering its embattled ‌currency last week.

“It could be them again,” Nick Twidale, chief market strategist at ATFX Global in Sydney, said ⁠of Monday’s move.

“Certainly not to the same extent as last week but reinforcing their stance ⁠that they ‌won’t accept a weak ⁠yen.”

Japan intervened to prop up ​the ‌yen against the U.S. dollar ​on Thursday, ⁠its first official currency action in nearly two years, two sources familiar with the matter told Reuters.
