USD/JPY was trading just above 154.00 after dropping close to two Yen on Monday to its weakest in six months, with no confirmation of intervention and little evidence of a broad carry unwind as AUD/USD sat near its highest since mid-May. US data should, on the face of it, have supported the Dollar: payrolls rose 162K versus a 53K consensus, while unemployment held at 4.1% and September 15-16 Federal Reserve hike odds increased to 58% from 49.4%, pushing the two-year Treasury yield to its highest since January 2025. Yet the pair still made a fresh six-month low and has fallen roughly six Yen since the September 2 peak just above 160.00, shifting focus to a repricing of the Bank of Japan rate path.
Japan’s policy rate has been 1% since June, but swaps now price a quarter-point move on September 18 at close to 97% and give October roughly a one-in-four chance, while US rates sit at 3.50% to 3.75% and the differential remains about 2.6 percentage points even if both deliver a quarter point. Japanese Government Bond yields have risen, with the 10-year clearing 3% on September 1 for the first time since 1996 and the two-year at its highest since 1995, as markets watch Japan’s 3.9% YoY wage consensus after 3.4%, a ¥2.87 trillion current account forecast after a ¥92.3 billion deficit, and GDP seen at 0.4% q/q versus 0.3%. US PPI is expected at 0.4% m/m after flat and 5.3% YoY after 4.7%, while CPI is seen at 0.4% m/m after 0.1% with 3.4% YoY and core at 2.4%; resistance sits at 154.50, 155.00, 156.00, the 200-day EMA near 158.00 and the 50-day EMA just under 159.50, with support at 154.00 then 153.50 and 153.00, and bearish bias while 155.00 holds as Stoch RSI stands at 82 daily and around 76 intraday.
Changing Market Dynamics and Strategy Implications
We are seeing a fundamental shift in how USD/JPY behaves, and we believe derivative traders should prepare for continued Yen strength in the coming weeks. The classic rate-differential trade has broken down, as evidenced by the pair falling to 154.00 despite strong US payroll data pushing the Fed hike odds to 58%. Because the Japanese leg is now driving the price action, we should focus on shorting USD/JPY on temporary rallies rather than buying the Dollar.
Historical Context and Trading Recommendations
Historically, we can look back at the dramatic Yen carry trade unwind of August 2024, when a tiny 15-basis-point hike by the Bank of Japan triggered a massive global market shakeup. Back then, the USD/JPY plummeted from over 161.00 to near 141.00 in a matter of weeks, proving how sensitive this pair is to Tokyo’s policy shifts. With the 10-year Japanese Government Bond yield breaking above 3% for the first time since 1996, the domestic pressure to tighten policy is stronger than it has been in decades.
For our short-term derivative strategies, we should target rallies toward the 155.00 resistance level to establish short positions or buy put options. The daily Stochastic RSI is still highly elevated at 82, indicating there is plenty of room for the market to fall before becoming oversold. We recommend keeping a close eye on the 154.00 support level, as a clean break below this point opens the door to untested territory down to 153.00.
