日本飞出“黑天鹅”，影响有多大？

Group 1 - The Bank of Japan (BOJ) has decided to gradually start selling its holdings of domestic exchange-traded funds (ETFs), indicating a tightening of monetary policy despite maintaining the policy interest rate at 0.5% for the fifth consecutive meeting [3][6] - Following the BOJ's announcement, the Japanese yen strengthened significantly, leading to a drop in the Nikkei index by 1.6% and causing a ripple effect across Asian markets, including declines in the Hang Seng Tech Index and South Korean stock indices [1][3][4] - Analysts suggest that the BOJ's move marks a significant step away from the ultra-loose monetary policies of the Abe administration, potentially signaling an interest rate hike in October [6][8] Group 2 - The BOJ's hawkish stance has led to expectations of a potential interest rate increase, with a survey indicating that most observers anticipate a rate hike before January next year, and market expectations of a 58% chance of a rate increase by the end of the year [6][9] - The normalization of monetary policy, including interest rate hikes and balance sheet reduction, is expected to exert upward pressure on the yen, which could lead to the unwinding of carry trade positions [8][9] - Historical data shows that past reversals of yen-funded carry trades have led to yen appreciation, declines in U.S. Treasury yields, and upward pressure on gold prices, while putting pressure on equity and commodity markets [8][9]
