NEW YORK (Reuters) - Japanese Prime Minister Fumio Kishida said on Thursday that excessive movement in the yen due to speculation cannot be overlooked and that his government would act "with a high level of vigilance" and intervene to support the currency again if necessary.
"Should there be any excessive volatility we will take action," he said in a speech at the New York Stock Exchange hours after Japan bought yen to prop up the currency for the first time since 1998.
