Japan’s Katayama says principles of Japan-US FX intervention remain in place

By Takaya Yamaguchi and Makiko Yamazaki TOKYO, Sept 24 (Reuters) Japanese Finance Minister Satsuki Katayama said on Thursday ​that the principles underpinning ‌the coordinated Japan-US currency intervention in July remain in place, signalling Tokyo s readiness to take joint action again if needed. The ‌principles ​since the previous joint ⁠intervention remain alive, ⁠Katayama told reporters, referring to the July 31 operation that Tokyo and Washington said was aimed at ​countering excessive volatility and disorderly market moves. Katayama said she would ⁠not comment on ⁠foreign exchange levels. The Japanese yen ​has weakened beyond 158 per dollar ​after the Bank of Japan s rate ‌hike to a 31-year high on Friday fell short of reassuring investors that more aggressive tightening may ⁠be on the way. Japanese authorities conducted rate checks in overseas markets on Friday, ⁠according to ‌sources familiar with the ⁠matter, a move often ​seen ‌as a precursor to currency ​intervention. Th
