USD bulls keep Japanese Yen subdued near 160.00 intervention threshold

• Intervention risks leave JPY bears cautious as USD/JPY trades within a range.
• The wide US-Japan interest rate gap and uncertainty over BoJ rate rises offer little encouragement to JPY bulls.
• The dollar and USD/JPY find support from geopolitical risks and expectations of a hawkish Fed.

Just below the psychological 160.00 level, USD/JPY is consolidating its gains in Friday’s Asian session, close to its highest point since early September. With the Japanese Yen (JPY) having recently fallen towards this critical threshold, renewed fears of intervention are keeping sellers of the currency on high alert.

Warning on Thursday that recent exchange rate moves had been too rapid, Japan’s top currency diplomat, Atsushi Mimura, reminded markets that it was too soon to forget the summer intervention. Japan’s Finance Minister Satsuki Katayama also indicated that the authorities were monitoring recent rapid, one-sided foreign exchange moves. She added that the government would respond appropriately to currency volatility and engage with the US Treasury. Expectations of an imminent December rate increase by the Bank of Japan (BoJ) have strengthened too, lending support to the JPY.

After a strong three-day advance to its highest level since April 2025, the US Dollar (USD) is taking a pause, providing a further constraint on USD/JPY. Even so, the near-term outlook appears to favour dollar bulls as markets increasingly accept that the US Federal Reserve (Fed) will lift borrowing costs again in December. Following hawkish remarks from Fed officials, traders have also begun to price in the possibility of a sizeable 50-basis-point (bps) increase next month.

Markets reprice the Fed outlook towards consecutive rate rises

With “a 25bps rate hike at the next FOMC meeting in December” now “fully priced in.”, analysts at MUFG/BTMU highlight a significant shift in the expected policy path. Market participants have gone further, they say, to “price in small probability of larger 50bps hike,” with “around 28bps of hikes priced by December, and 43bps of hikes priced by the following meeting in January.” In the analysts’ assessment, this pattern “indicat[es] that even if the Fed hikes by 25bps in December it is now expected to quickly follow up with another 25bps hike at the start of next year.”

The timing and pace of further BoJ rate increases, by contrast, remain unclear to investors. Together with the substantial US-Japan interest rate gap, that uncertainty sustains the so-called carry trade and may offer little meaningful support to the JPY. Risks in the Middle East could also bolster safe-haven demand for the dollar, implying that buyers are more likely to step in on any corrective decline in USD/JPY. The pair nevertheless remains on course for a third consecutive weekly gain.

USD/JPY Retains a Bullish Technical Bias

Trading above both the 100-day Simple Moving Average (SMA) at 158.97 and the 50.0% Fibonacci retracement at 158.49 leaves USD/JPY with a bullish near-term bias. The pair has edged back above the 61.8% retracement at 159.79, making this immediate support and suggesting that upward pressure persists. The next significant obstacle lies at the 78.6% retracement of 161.64; a sustained move beyond it would clear the way to revisit the cycle high at 164.00.

Should the pair slip below the 61.8% Fibonacci retracement at 159.79, support could emerge around the 100-day SMA at 158.97, which underpins the broader bullish structure. Further down, the 50.0% retracement at 158.49 precedes the lower Fibonacci levels of 157.20 and 155.59, which stand ahead of the structural anchor at 152.99.
