TOKYO (Reuters) - Japan has highly likely intervened in the foreign exchange market to prop up the yen, former top currency diplomat Mitsuhiro Furusawa told Reuters on Tuesday.
The yen jumped against the dollar on Monday, with traders citing yen-buying by Japanese authorities as a trigger for the bounce in a currency languishing at levels last seen more than three decades ago.
The dollar tumbled to a low of 154.40 yen from as high as 160.245 earlier Monday.
