Bank of Japan Governor Kazuo Ueda suggested that the December 19 meeting might end the long pause in rate hikes, driven by consistent inflation and new fiscal stimulus. This anticipation has led markets to assign an over 80% probability of a rate increase in December, boosting the Japanese Yen (JPY) and possibly setting the stage for a stronger currency through 2026, according to Commerzbank’s analyst Antje Praefcke.
In Nagoya, Ueda hinted that the central bank would consider raising interest rates, weighing economic activity, prices, and market developments. Following his speech, the market adjusted its expectations, significantly strengthening the yen against the dollar. The likelihood of a December rate hike exceeds 80%, with January as a potential alternative.
Interest Rate Expectations and Government Support
The new government seems to be supporting the Bank of Japan, as indicated by Finance Minister Satsuki Katayami. Analysts predict that the expected rate hike could signal the beginning of a more favourable period for the yen in 2026.
With the market now pricing in an over 80% chance of a Bank of Japan rate hike on December 19, the path of least resistance for the Yen appears to be upward. We have seen Japan’s core CPI stay stubbornly above the 2% target for nineteen straight months, with the latest November 2025 data showing a 2.9% year-over-year increase. This persistent inflation, combined with the government’s new fiscal stimulus, gives the central bank a clear mandate to act.
We are already seeing this policy pivot reflected in the spot market, as USD/JPY has fallen from near 155 just last month to trade below 148 today. This sharp move indicates that the popular and long-standing carry trades funded by a weak yen are being unwound rapidly. Derivative traders should view this as the beginning of a larger trend, not a temporary reaction.
Volatility and Strategic Opportunities
The options market is signaling expectations of significant movement in the coming weeks. One-month implied volatility for USD/JPY has surged to its highest level since the bond market tremors of early 2024, suggesting traders are preparing for a major breakout. This environment favors strategies that benefit from both a strengthening yen and rising volatility.
Looking back at the Euro’s reaction when the ECB began its tightening cycle in 2022 provides a useful guide for what we might expect for the Yen through 2026. Therefore, traders should consider buying JPY call options or establishing bearish positions on USD/JPY via put options to capitalize on this widely anticipated policy shift. The window to position for this move ahead of the official announcement is closing.
