Japan yen stepping down from the throne of escape currency!

11/19, Russia protests after the United States shifts to a stance that tolerates the use of U.S.-made missiles by Ukraine inside Russian territory, and revises its nuclear doctrine to loosen the conditions for nuclear weapon use(basic principles); as a result, financial markets reacted with risk-averse buying of U.S. Treasuries, gold, Swiss francs, and yen. However, yen buying did not last long, and in the New York market it was pushed down to the upper 150s per dollar at the close. This explains the background to Japan's yen as a safe-haven currency losing its seat, and the future direction of the Swiss franc/yen pair.
