Bank of Japan lifts its policy rate to the highest level since 1995, sparking a broad rise across Asian equity markets
Executive summary: The Bank of Japan raised its key interest rate to 0.5 %, the highest level in 31 years, citing the need to contain inflation risks amplified by the Middle‑East war. The hike signals a shift from ultra‑easy policy, influencing yen strength, Japanese borrowing costs, and risk appetite across Asian equities.
Who is involved: Bank of Japan (Governor Kazuo Ueda), Japanese financial markets, Asian equity investors, global commodity markets.
Likely next: Markets will watch the BOJ’s upcoming policy‑meeting minutes, Japan’s August CPI release (early October), and the yen’s reaction; further tightening is possible if inflation stays above target.
The BOJ announced a 0.25‑percentage‑point increase, bringing the short‑term rate to 0.5 %, its highest since 1995. The move is framed as a pre‑emptive response to rising global inflation pressures, notably from the Middle‑East conflict. Asian indexes — Nikkei 225, Topix and China’s CSI 300 — all advanced in early trading, suggesting investors view the tightening as a sign of policy normalisation rather than a growth shock. The decision also underscores the BOJ’s willingness to act independently of the Federal Reserve’s pace.
