[Former Bank of Japan Official: Besent's 'Abnormal' Intervention May Undermine BOJ's Credibility] A former senior official of the Bank of Japan has warned that U.S. Treasury Secretary Besent's 'abnormal' intervention in Japan's monetary affairs could undermine the credibility of the Bank of Japan and trigger greater volatility in global markets. This comes as the market anticipates the Bank of Japan will raise interest rates by 25 basis points at next week's meeting, a faster timeline than previously cautious projections. In recent weeks, Besent has intensified his verbal pressure, provoking global traders to bet against him and claiming to have insider knowledge of the Bank of Japan's intentions. Although Japan's top government officials and the Bank of Japan have largely refrained from publicly responding to Besent's remarks, Finance Minister Katsuyuki Katayama stated that the U.S. Treasury Secretary's warning to bond traders, 'I am the dealer,' sounds 'a bit intimidating' when translated into Japanese.
