The Bank of Japan is preparing for possible losses on its bond transactions by increasing its provisions. This suggests that the bank expects interest rates to rise. For fiscal 2024, the Bank has set provisions at 100% for the first time ever. This funding comes from the income generated by its bond and financial activities. Typically, the Bank targeted 50% for provisions before fiscal 2024, reaching a maximum of 95% in fiscal 2018. Recently, provisions increased by 472.7 billion yen ($3.28 billion), following a 922.7 billion yen rise in fiscal 2023. When the Bank of Japan raises rates, it affects the yen. Expectations of higher rates caused the yen to strengthen from July to September 2024, which led to changes in some yen carry trades and impacted global markets. The Bank’s full provisioning clearly shows that it believes there is a significant risk of loss in its bond holdings if interest rates keep climbing. This is a proactive financial cushion made from earlier earnings to prepare for declining bond values, which often occur when rates increase. Notably, the level of provisions has doubled in just two years. Even with elevated preparations in previous years, such as during fiscal 2018, the Bank never allocated its entire income to cover potential losses. This cautious approach suggests that the current situation is more than just routine accounting—it reflects serious expectations. By fully committing income to counteract expected declines in market values, the rise in domestic rates is seen as not just a prediction but as active preparation. These changes indicate a clear policy intent. This shift is important for those watching the derivative markets. Rising rates in Japan directly impact strategies built around stable or declining yen values. Expectations alone have already caused the yen to rise from July to September, leading to real consequences for leveraged positions tied to interest rate differences. The effect on carry trades is not just a theory; it has happened. Increased exchange rate volatility followed suit, leading to adjustments in leveraged yen positions, and raising the cost of maintaining those positions. Funding strategies that relied on low yen borrowing costs have become riskier. Even traders not directly involved with the yen have felt the effects in cross-currency spreads and volatility in Asia-Pacific options. Going forward, we should closely monitor volatility trends in the JPY market. Forward implied rates are no longer confidently predicting stable outcomes. This is influenced not only by market movements but also by hedging actions driven by rising uncertainty about interest rates. Those involved in strategies that sell volatility or have short gamma positions might need to rethink their risk levels as we approach the next rate decision. Focusing on short-term resets and broader collars can be wise. It’s better to avoid aggressive premium seeking in yen-related derivatives until we hear an official policy signal from the Bank. While the income allocation is telling, the response in swaps, credit default swaps (CDS), and Japanese Government Bond (JGB) futures will really test the market’s conviction. We should pivot from directional bets on yen appreciation to more effective hedges against rate-related shifts. Not every move needs to be extreme; timing and skew exposure will be crucial in the coming month. Careful management of hedge ratios and delta exposures in multi-currency portfolios can help maintain a balance between protection and participation. We shouldn’t try to predict the exact announcement, but we can adjust our positions to reflect the clear shift in odds already indicated by the Bank’s provisioning.
