The USD/JPY pair is currently fluctuating between ¥157.63 and ¥158.92 on Thursday, influenced by session measurements. It has seen a decline of 0.57% to 0.62% today after reaching its peak level since July 2024 during Wednesday’s trading session. The recent decline is minimal and lacks significant structural implications — the pair has retraced to the mid-¥158s after reaching close to ¥160 at its peak, which is exactly the critical zone in the current USD/JPY narrative. The ¥160 level does not serve as a technical indicator in the traditional context. This represents a pivotal moment for a multi-decade breakout that, if maintained, would indicate the most significant change in the long-term trend of USD/JPY since the currency pair was last at these levels in 1990. Every other data point — the Federal Reserve’s PCE revision, the Bank of Japan’s hold, the Iran war’s stagflation implications, the RSI at 70.06 — must be analyzed through a singular lens: USD/JPY is nearing a pivotal threshold, and the events that unfold between ¥160 and ¥161.50 will shape the pair’s direction for years to come, rather than just weeks. The moving average structure clearly indicates a bullish trend across all significant timeframes. The pair is currently positioned above the SMA-20 at ¥158.13, the SMA-50 at ¥156.17, and the SMA-200 at ¥154.07. Trading above all three significant moving averages concurrently indicates a market that is in a confirmed uptrend across short, medium, and long-term perspectives.
The Ichimoku Kijun support at ¥157.05 serves as the immediate floor beneath the current price, offering a dynamic support level that has remained intact during the recent upward movement. The 100-period EMA on the 4-hour chart is positioned around ¥158.00, while the lower boundary of the ascending parallel channel is at ¥158.92 — precisely where Thursday’s pullback is establishing support, indicating a notable correlation. The lower channel boundary represents the critical point where the structure necessitates buyer intervention, and the price action observed on Thursday aligns perfectly with this expectation. The Federal Reserve’s decision on Wednesday served as the immediate catalyst for the surge toward ¥160, followed by Thursday’s measured retreat. The Fed maintained rates at 3.50% to 3.75% as anticipated, yet the accompanying statements were notably hawkish: the central bank increased its year-end PCE inflation forecast due to risks from elevated energy prices linked to the Iran conflict, revised its 2026 growth outlook upward, and upheld its expectation for just one rate cut in 2026 and another in 2027. This represents a notable change from the market expectations — just this past Tuesday, the prevailing assumption was that one Fed cut would occur by December. The adjustment indicating no cuts in 2026, with the initial reduction expected in the first half of 2027, has established a dollar interest rate premium over the yen that is unlikely to diminish in the foreseeable future.
The mechanism is both straightforward and powerful. The Federal Reserve currently stands at a range of 3.50% to 3.75%. The Bank of Japan maintains its interest rate between 0% and 0.1%. The interest rate differential between the two currencies stands at around 350 basis points, rendering the dollar significantly appealing as a yield-bearing asset in comparison to the yen for carry trade purposes. With each passing day that the differential remains and each week that the BoJ postpones its normalization cycle, the underlying pressure on USD/JPY indicates a clear trajectory: upward. The Fed’s hawkish stance, influenced by oil prices exceeding $110 and a geopolitical landscape that fosters persistent inflation rather than a temporary spike, does not suggest a scenario where that differential will narrow in the near future. Powell’s press conference language was definitive — the disinflation of goods inflation is essential for easing, and oil prices exceeding $100 are directly hindering the realization of that essential condition. The Bank of Japan’s choice to maintain rates unchanged for the second consecutive meeting represents a crucial component of the fundamental equation that supports the durability of the USD/JPY bull case. The Bank of Japan’s rationale for maintaining its position is clear and significant: the surge in crude oil prices driven by the conflict in Iran has introduced stagflationary risks for Japan, complicating the normalization of interest rates considerably. Japan relies on imports for nearly all of its oil and natural gas supplies. When oil is priced between $110 and $119 per barrel — the range observed for Brent on Thursday — each imported barrel incurs higher costs for Japanese businesses and consumers in yen, leading to inflationary pressures while simultaneously posing challenges to economic growth. Increasing rates in such a context would exacerbate the growth challenges without effectively addressing the inflation issue, as the inflation is rooted in supply constraints rather than demand factors.
BOJ Governor Ueda indicated on Thursday that “rate hikes are possible if price trend is intact” — a conditional statement that lacks clarity regarding the timing for the market. The ongoing conflict in Iran and its effect on oil prices is the primary factor in this situation, and with oil priced at $110, the Bank of Japan cannot pursue aggressive rate normalization without the risk of exacerbating economic harm. The stagflationary environment resulting from the conflict has led to rising import costs that diminish real purchasing power while growth decelerates. This scenario is exactly what maintains the Bank of Japan’s current stance and sustains the carry trade against the yen. Until a credible diplomatic resolution to the conflict normalizes oil prices, or Japanese domestic inflation data is robust enough to overshadow growth concerns, the BoJ finds itself in a constrained position. The USD/JPY bull’s most resilient support comes from that trap. The ¥160 level requires careful consideration of its historical context, as its importance reaches well beyond the 4-hour chart. The last instance of USD/JPY trading consistently above ¥160 occurred in 1990 — the zenith of Japan’s asset bubble economy, a period when the nation’s equity and real estate markets reached their historical peaks, preceding the prolonged deflationary downturn that ensued.
A break and sustained hold above ¥160, and particularly above ¥161, would not merely signify a technical breakout — it would indicate a structural reversion to a USD/JPY pricing regime that the global currency market has not experienced in 36 years. The ramifications of this for global capital movements, for the earnings of Japanese corporations (which see significant advantages when the yen depreciates), for the valuation of Japan’s substantial government bond assets (which are adjusted in yen terms), and for the credibility of the Bank of Japan are all considerably more significant than any individual trading day. The BoJ has taken action to support the ¥160 level on several previous instances when the pair neared it from beneath. In 2024, as USD/JPY approached ¥160, Japanese authorities engaged in foreign exchange intervention, expending around $62 billion to limit the rise. The historical context of intervention at ¥160 is now a significant element in the present scenario — not due to the certainty of intervention, but because the market is aware of its potential, and this awareness induces caution among momentum buyers nearing that threshold. The 4-hour channel top is positioned at ¥160.79, where previous failures and the upper boundary align to limit the potential for upward movement. A clean break above ¥160.79 would expose ¥161.50, and a sustained break above ¥161 would signal that the 36-year barrier has been definitively breached — a market event that would trigger significant position changes across institutional desks globally.
