日本利率升至30年新高，日本加息背后如何影响全球股市？

Group 1 - The Bank of Japan has raised its policy interest rate from 0.5% to 0.75%, marking the highest level in nearly 30 years, which aligns with market expectations but has significant global implications [2] - The widening interest rate differential between the US and Japan has accelerated capital outflows, with the current target range for the US federal funds rate at 3.5% to 3.75%, while Japan's rate remains significantly lower [3] - The capital outflow and the persistent high interest rate differential are impacting the Japanese yen's value, leading to concerns about the stability of Japan's financial system and the potential need for further rate adjustments to stabilize the yen [4] Group 2 - Japan's debt-to-GDP ratio exceeds 260%, and the recent rate hike will increase the debt burden, putting pressure on Japan's fiscal situation [5] - The Federal Reserve's monetary policy has a more significant global influence compared to the Bank of Japan, and any future rate cuts by the Fed could narrow the interest rate differential, providing more operational space for Japan's monetary policy [6] - If the Fed does not cut rates in 2026, the Bank of Japan may be forced to continue raising rates, which could exacerbate the negative impacts of Japan's high debt levels [5][6]
