The Narrow US-Japan Yield Spreads
US-Japan yield spreads are decreasing, which traditionally supports the yen. Nevertheless, the options market reflects a lack of activity, with risk reversals showing a slight premium for those protecting against yen strength. The USD/JPY pair has been stable since mid-November, trapped in the mid-154s to upper-157s, with no expected significant changes unless it breaks out of this range. The FXStreet Insights Team gathers market observations from leading experts and insights from various analysts. Given the yen’s strength amid rising geopolitical risks from Venezuela and the South China Sea, there is a noticeable gap between fundamentals and the spot price. The USD/JPY pair remains tightly bound, creating tension for traders, indicating a buildup for a potential big move. The rise in Japanese government bond yields significantly supports a stronger yen. The 10-year yield hitting 2.12%, a level not seen since 1999, marks a striking change from the sub-1% yields experienced through much of 2023 and 2024. This increase is driven by ongoing domestic inflation; Tokyo’s core CPI in December 2025 stayed at 3.5%, putting substantial pressure on the Bank of Japan.Interest Rate Differences Between US and Japan
This situation has caused the interest rate gap between the US and Japan to shrink, making the yen more desirable to hold. The difference between 10-year US Treasuries and Japanese Government Bonds (JGBs) has narrowed by over 50 basis points since November 2025. This points to a lower USD/JPY exchange rate. However, the options market presents a contrasting view, showing complacency with little movement in the spot market. One-month implied volatility for USD/JPY has dropped to a six-month low of 6.5%, suggesting traders are not preparing for a major change soon. This low volatility results in relatively cheap option premiums. In the upcoming weeks, there’s an opportunity to sell volatility while the currency pair remains between mid-154s and upper-157s. A short strangle strategy, selling puts around 154.50 and calls around 157.80, can capitalize on premium decay. This strategy is effective as long as the currency pair stays within this range. Alternatively, traders should be ready for a break below the range’s floor. Given the fundamental pressures, a significant drop below 154.50 could lead to a swift move toward the 152.00 level. Buying inexpensive, out-of-the-money USD/JPY puts can be a cost-effective way to prepare for this possible breakout.
