■Bank of Japan Deputy Governor Uchida who ran to put out the fire after the major stock price crash
　At the press conference (31st) after the monetary policy meeting on 7/30-31, Governor Kazuo Ueda completely changed his explanations so far.
　“Exchange rate fluctuations are a risk, and interest rates will be raised to respond to them,” “in the future, if the price outlook is going well as expected, interest rates will continue to be raised,” “even if interest rates are raised to 1% even if they are underestimated, they will not reach neutral interest rates,” etc., but until now they have been too careful and too dovish, but the atmosphere has completely changed.
　Surprised by this, traders resolved their accumulated speculative selling positions in yen, and the yen carry trade was rewound all at once, which caused the entire global risk asset market to crash. Even crypto assets such as bitcoins have crashed.
