The currency pair softened slightly from its recent highs due to these remarks. Daily momentum remains flat, with the Relative Strength Index (RSI) indicating possible decline signs. Resistance levels are noted at 155 and 156.10, while support is seen at 154.40 and 153.10, corresponding to the 21-day moving average.
Potential For Sudden Reversal
With USD/JPY pushing against the 155 level, the primary tension is between weak yen fundamentals and the growing risk of government intervention. The fundamental case for a weaker yen is strong, fueled by a hesitant Bank of Japan and Japan’s own fiscal pressures. This creates a difficult environment where the trend is up, but the potential for a sudden, sharp reversal is high.
This view is strengthened by recent data from our perspective in November 2025. Japan’s core CPI for October just came in at 2.7%, below expectations and further reducing any pressure on the BOJ to tighten policy soon. In contrast, the latest US non-farm payrolls report showed a robust 210,000 jobs added, cementing the wide interest rate differential that favors the dollar.
We have seen this scenario before, specifically with the interventions in late 2022 and again in the spring of 2024. In those instances, Japanese authorities stepped in after the pair crossed similar psychological levels, triggering rapid, multi-yen drops that punished yen short-sellers. The current verbal warnings from Finance Minister Katayama are echoing the same language used just before those past actions.
Strategies For Traders
Therefore, a prudent strategy for the coming weeks involves buying USD/JPY put options. This offers a direct hedge against a sudden drop caused by intervention, effectively acting as insurance on any long positions. Using a bear put spread can help reduce the premium paid for this protection, making the hedge more cost-effective.
Alternatively, traders can look to buy volatility, as the market is clearly coiled for a large move. Purchasing a long strangle, which is buying both an out-of-the-money call and an out-of-the-money put, would be profitable on either a sharp breakout above 155 or a sudden plunge. One-month implied volatility has already ticked up to over 11%, indicating that the options market is actively pricing in this heightened risk of a significant move.
