USD/JPY hovered just under 159.50 on Thursday, up 0.05% within a 42‑pip range, extending a fifth session of modest gains. The pair remains below a declining 50‑day EMA that sits on 160.00, while a rising 200‑day EMA is positioned just under 158.00; daily Stoch RSI was near 69 and rising.
In late July the pair pushed to just under 164.00 before a joint Tokyo–Washington operation — the first since 1998 — drove it to the 155.00 area within two sessions. A record 8.45 trillion yen was deployed in one session, followed by about 5.3 trillion more; four weeks later spot is within roughly a dozen pips of the midpoint of that move. Japan’s policy rate is 1.00% versus a US target range of 3.50% to 3.75%, a gap of roughly two and a half percentage points, and even 1.25% in September would still leave better than two points. Tokyo core CPI (excluding fresh food) rose to 1.9% in July from 1.6% and above a 1.7% forecast, while national core was 1.8% versus a 2% target; consensus now sees Tokyo core at 1.7%. Market pricing for September moved from about 65% on August 7 to just under 80%, as Tokyo data are due 23:30 GMT with headline and ex food and energy at 2% prior, core from 1.9%, and July unemployment at 2.5% unchanged; the CPI base year shifted from 2020 to 2025. US events include the Fed Chair at Jackson Hole at 14:00 GMT Friday, alongside the annual benchmark revision, with Chicago PMI at 13:45 GMT seen at 57 versus 57.6; Japan retail trade follows at 23:50 GMT Sunday from 0.5% y/y and -4.1% m/m. Next week brings US manufacturing at 14:00 GMT Tuesday seen at 55.3 versus 55.6, job openings at 7.359 million, private payrolls at 12:15 GMT Wednesday from 44K, services from 54.1, and Friday payrolls at 12:30 GMT after -23K with unemployment 4.1%, ahead of the Bank of Japan meeting on September 17–18.
Technical Outlook and Recent Interventions
We watch USD/JPY hovering just beneath 159.50 as it faces its fifth consecutive session of grinding higher without real breakout momentum. The pair is currently trading below its declining 50-day Exponential Moving Average (EMA) at 160.00, while the rising 200-day EMA sits comfortably lower near 158.00. With the daily Stochastic RSI climbing near 69, we expect one last short-term push toward the 160.00 handle before a reversal.
This retracement follows massive joint interventions by Tokyo and Washington, reminiscent of the historic 9.8 trillion yen market rescue in 2024. Despite spending an initial 8.45 trillion yen followed by another 5.3 trillion yen to push the pair down to 155.00, the market has already clawed back half of those losses. We see this as proof that massive currency interventions only provide temporary relief when the underlying macroeconomic drivers remain untouched.
Yield Differentials, Fiscal Pressures, and Trade Setups
The primary driver is the wide yield gap, as Japan’s 1.00% policy rate pales in comparison to the US target range of 3.50% to 3.75%. Even if the Bank of Japan raises its rate to 1.25% in September, the remaining two-percentage-point spread keeps the carry trade highly profitable. Meanwhile, Japan’s widening fiscal deficit, aggravated by tax cuts and government stimulus, continues to weigh heavily on the yen’s long-term value.
Political pressure is also building, pushing September rate hike expectations up to nearly 80% from 65% earlier this month despite Tokyo’s core CPI hovering below the 2% target at 1.9%. Since current inflation is mostly imported through a weak exchange rate, the central bank is using rate hikes as a currency defense tool rather than an inflation remedy. We anticipate heavy volatility as we head into upcoming US labor data and the Bank of Japan’s policy meeting on September 17-18.
We recommend that derivative traders maintain a bearish bias on the pair as long as the 160.00 resistance level holds. Selling rallies near this declining 50-day EMA offers an attractive risk-to-reward setup, targeting support shelves at 159.00 and 158.00. Any daily close above the 160.00 mark will invalidate this bearish stance, shifting our focus to higher targets at 160.50 and 161.50.
