USD/JPY Tests 160 as Tokyo Turns Up the Heat

USD/JPY traded as high as roughly 160.04 on Thursday, November 12 as the U.S. Dollar surged on renewed Fed tightening expectations. Markets now price roughly a 90% chance of another December hike, while the 10-year Treasury yield pushed back above 5%. That widening U.S.-Japan rate gap continues to overwhelm the Japanese Yen, even as Japan’s own inflation problem worsens. October wholesale inflation accelerated to 7.1%, while yen-based import prices jumped 24.8% year-over-year, highlighting how currency weakness is feeding directly into domestic costs.

That is why 160 matters today. Japan’s top currency official Atsushi Mimura called recent moves “excessively rapid” and reminded markets not to forget this summer’s intervention, while Tokyo continues coordinating closely with the U.S. Treasury. There is no confirmed intervention or rate check today, but the escalation ladder is becoming clear: stronger verbal warnings first, then potentially rate checks, followed by MOF-directed Japanese Yen purchases executed through the BOJ if the move becomes disorderly. With parts of the BOJ still arguing for caution on further hikes, monetary policy alone is not yet closing the gap. For now, USD/JPY remains a tug-of-war between a fundamentally strong U.S. Dollar and an increasingly credible threat that Tokyo steps back into the market above 160.

USD/JPY Daily Price History

USD/JPY is pressing straight into the intervention zone again. Price is around 159.85 after trading above 160 intraday, and the pair has now reclaimed the 21-, 50-, 100-, and 200-day moving averages. That is a meaningful technical repair after the September washout. The short-term structure has flipped back bullish, but the market is immediately running into the 160.40 area, which is the next major resistance shelf and the exact zone where intervention risk becomes part of the chart, not just the macro story.

Momentum is strong but stretched. MACD is positive and accelerating, with the histogram expanding. That says the U.S. Dollar still has control. Stochastics are above 90, though, so the pair is deeply overbought heading into resistance. That does not mean it has to reverse, but it does mean chasing above 160 has poor asymmetry when Tokyo can hit the tape without warning.
