BOJ Policy Shifts: Implications for Global Markets and Investment Strategies

The Bank of Japan's (BOJ) 2025 policy normalization has sent ripples through global markets, marking a pivotal shift from decades of ultra-loose monetary policy. By raising the policy rate to 0.5% in January 2025—the highest since 2008—and initiating a phased sale of ¥37 trillion ($251 billion) in ETF holdings, the BOJ has signaled its intent to rebalance inflation, stabilize the yen, and recalibrate its balance sheetBank of Japan: hitting a 17-year high | J.P.

These moves, while aimed at domestic stability, have profound implications for global investors, necessitating a strategic reallocation of portfolios to navigate heightened volatility and shifting capital flows.
