HSBC warns that Japan's currency risk premium has surged to levels not seen in over a decade, complicating monetary policy and market stability. The bank underscores that no immediate solutions exist for the yen's growing volatility.
- Yen risk premium rose to 12.8 bps in January 2026, up 43% from 8.9 bps average pre-2025
- Japan’s public debt-to-GDP ratio reached 248% in 2025
- U.S. 10-year Treasury yields averaged 4.7% in January 2026
- Corporate hedging costs increased by up to 15% for multinationals in Q4 2025
- Bank of Japan maintains cautious stance despite market stress
- No immediate policy tools available to reverse trend without structural reforms
The yen’s risk premium climbed to 12.8 basis points in early January 2026, marking a 43% increase from its pre-2025 average of 8.9 bps, according to internal HSBC analysis. This spike reflects heightened investor concerns over Japan’s fiscal sustainability and potential shifts in Bank of Japan (BoJ) policy. Despite the BoJ maintaining its ultra-low interest rate stance, the widening spread between Japanese and U.S. sovereign yields has intensified speculative pressures on JPY. A key driver remains Japan’s public debt-to-GDP ratio, which reached 248% in 2025—up from 231% in 2023—raising doubts about long-term debt management. As global investors reassess safe-haven positioning, the yen’s appeal as a low-cost funding currency has eroded. Meanwhile, rising U.S. Treasury yields—10-year yields averaging 4.7% in January—have further widened the yield differential, increasing the cost of carry for yen-funded trades. Market participants are now grappling with implications for corporate hedging strategies and foreign direct investment flows into Japan. Multinational firms with significant operations in Tokyo reported increased FX exposure costs, with some adjusting hedges by up to 15% in Q4 2025. The impact is particularly acute in export-oriented sectors such as automotive and electronics, where profit margins are under strain due to sudden appreciation. While the BoJ has signaled readiness to intervene if needed, it has refrained from unilateral action, citing concerns over undermining market integrity. Analysts note that structural reforms—such as boosting tax revenues or restructuring pension liabilities—would be required for lasting improvement, but political consensus remains elusive.
