Ex-BOJ official predicts no yen intervention until breach of 150 threshold

Japan will forgo intervening in the market unless the yen plunges past 150 to the dollar and becomes a huge political headache for premier Fumio Kishida, said a former central bank official who was involved in Tokyo's market foray a decade ago. When the dollar broke above the 145-yen line that triggered intervention last year, speculation began mounting that Tokyo would soon step into the market to support its currency. The public's mood is key to when authorities intervene due to the strong attention Japanese firms and households place on yen moves, said Takeuchi.
