Sugi: Japanese authorities deliberately reduce the predictability of market intervention in exchange rates.

Sina Finance reported on March 30th that, despite the recent decline in the Japanese yen prompting authorities to increase warnings about intervention, Mizuho stated that the latest remarks highlight Japan's desire to keep the foreign exchange market alert, rather than defending key levels. "Japan's foreign exchange policy has always avoided formal rules and tends to make discretionary judgments based on the current market conditions. This position itself deliberately reduces predictability," wrote Masayuki Nakajima, a senior strategist at the Japanese bank in a report.
