snapped from just under ¥157.00 to briefly below ¥156.00, then bounced back, a textbook shakeout where both sides were hit. The pair had just tagged a two-week high around ¥156.80–156.85 before sellers faded the move and dragged it toward the mid-155s. That reversal shows how sensitive the pair is to small changes in policy rhetoric: one hawkish BoJ headline was enough to knock more than a full figure off the high, but dip-buyers stepped back in as soon as price approached the 155.70–155.80 area.
The key short-term pivot is clustered around ¥155.75 on USD/JPY. That level lines up with the 200-period SMA on the 4-hour chart and the 23.6% Fibonacci retracement of the latest leg higher from ¥152.34 to ¥156.85. A clean break under 155.75 opens a classic Fibonacci staircase: first the 38.2% zone near ¥155.15, then the 50% area around ¥154.60 and finally the 61.8% retracement near ¥154.06. Below that, the broader support band that has been working since autumn sits around 154.45–155.00. On momentum, RSI on the 4-hour chart has cooled back toward 55 after failing to hold near 70, signaling positive but not overextended pressure. MACD is hovering just above the signal line and close to zero, reflecting modest bullish bias but no powerful trend impulse. On the topside, the real problem is still 160.00. That level triggered direct Ministry of Finance intervention more than once and is anchored by the prior spike above 151.95 that reversed violently and sent USD/JPY all the way down toward 140.00 while the VIX printed its third-largest spike on record in early August. Bulls know that pushing back into 160.00 has a history of ending badly, which is why chasing strength near current levels is far less attractive than waiting for pullbacks or clear breaks.
On the policy front, the most aggressive voice right now is Hajime Takata. He is openly calling for a “gear shift,” arguing that the inflation target is essentially reached and pushing for further rate hikes. He already dissented in January, preferring a move to 1.0% instead of holding at 0.75%. That kind of stance is exactly what allowed the yen to rip briefly, knocking USD/JPY below ¥156.00 in minutes. At the same time, political decisions are pushing the other way. Prime Minister Takaichi has nominated two new BoJ board members known for strong reflationist leanings and comfort with ultra-easy policy. That softens the path of normalization and tells the market that even if Takata keeps pressing, he is unlikely to dominate the board. Pricing in OIS still reflects roughly 17 bps of tightening penciled in by April and another move almost fully priced by year-end, but the overall message from Tokyo is “slow and cautious,” not “aggressive hiking cycle.”
Inflation dynamics are now driven less by classic domestic demand overheating and more by the mix of weak yen, fiscal support and imported energy. Higher policy rates should strengthen the currency because they increase the return on yen assets, but as long as the BoJ insists on moving in tiny increments while the Fed stays relatively restrictive, rate differentials still work in favor of USD/JPY upside on rallies. At the same time, any sustained spike in crude triggered by Middle East tension or supply scares would hit Japan hard as a net energy importer. A jump in oil prices raises the risk of imported inflation without giving the BoJ much room to respond. MUFG correctly flags that combination as a downside risk for currencies from energy-importing countries like Japan and parts of Europe and a potential support factor for the dollar if oil rips higher again.
Geopolitics is pulling the pair in two directions. On one side, rising tension around US–Iran nuclear talks and broader Middle East risk supports the yen’s safe-haven role. That contributed to the latest slide from the ¥156.80–156.85 zone down to the confluence support near 155.75, as markets trimmed carry trades into event risk. On the other side, the same risk backdrop can underpin the dollar through classic flight-to-quality flows into Treasuries and USD cash. When those two forces collide, USD/JPY tends to chop violently inside the range rather than trend cleanly, which is exactly what is visible now in the whipsaw moves between roughly ¥155.50 and ¥157.00.
The yen picture is cleaner when you look at the crosses. has rebuilt a bullish structure with a near-term support shelf around 183.80 and a secondary demand band at 182.65–183.16, with a deeper base in the 180.81–181.20 area. is holding above the 2024 highs near 208.00, with repeated support tests around 210.00 and a well-defined ladder of demand at 209.62, 209.00 and then 208.12. Those levels show that markets are still comfortable selling the yen against higher-yielding currencies when dips present themselves, even after last year’s massive unwind from 160.00. That relative strength of EUR/JPY and GBP/JPY tells you that the broader theme remains yen-weak on rallies, but USD/JPY is constrained by the very visible 160.00 intervention line and the fact that the dollar index itself is sitting into resistance. That is why the cleanest directional opportunities for pure yen weakness may stay in the crosses, while USD/JPY trades more like a range with hard boundaries rather than a one-way trend.
Putting it all together, the picture is clear. Short-term, USD/JPY is leaning on a strong confluence support at roughly ¥155.75 backed by the 200-SMA on the 4-hour chart and the 23.6% retracement of the latest upswing. Below that, there is a tight stack of downside levels at ¥155.15, ¥154.60 and ¥154.06, then the broader structural shelf around 154.45–155.00 that has acted as a pivot since October. On the topside, any push back through the recent high at ¥156.80–156.85 opens room to re-test ¥157.00–158.00, but the real battle remains around 160.00, where two prior interventions and a violent carry unwind showed how quickly conditions can reverse. Policy signals are mixed: Takata’s push for a move toward 1.0% policy rates is yen-positive, but the new dovish board appointments, the gradualism priced by markets and the risk of higher oil prices all limit how far Japan can realistically tighten.
Geopolitics adds volatility but not a clear direction, as safe-haven JPY flows fight with defensive demand for dollars. Under these conditions, the edge sits with a Sell-the-rally stance on USD/JPY rather than chasing breakouts. While the pair holds below the 160.00 ceiling, strength into the upper 156s and 157s favors fading for another rotation down toward 155.15–154.60, with a deeper extension toward the low-154s and even the 152.34 swing low if global risk sentiment sours or BoJ communication leans more consistently hawkish. A weekly close above 160.00 would invalidate that bias and flip the setup into a momentum-driven upside break, but until that happens, the risk-reward profile points to bearish / Sell on strength as the dominant strategy for USD/JPY.
