USD/JPY Bulls Eye Breakout Above 159.65 Fibonacci Hurdle

USD/JPY is trading near its weekly high after attracting dip-buyers for a fourth straight session, with spot prices holding close to 159.65. The pair’s advance rests on rising bets for a Federal Reserve rate hike, a wide U.S.-Japan interest rate gap, and lingering concerns over Japan’s fiscal position. Markets are positioning ahead of Bank of Japan Deputy Governor Ryozo Himino’s speech Thursday and Fed Chair Kevin Warsh’s Jackson Hole address Friday, both seen as key signals for the pair’s next move.

Dip-Buyers Return for a Fourth Day

The pair turned positive for a fourth consecutive session following an intraday dip toward 159.00 during Thursday’s Asian trading. Wednesday’s slightly hot U.S. inflation data reaffirmed market pricing for at least one Fed rate hike before year-end, keeping the dollar near an eight-day high. The yen continues to struggle against that backdrop even as the Bank of Japan holds its own tightening bias: the central bank raised its policy rate to 1.0% in June and held it there in July, and markets now price roughly an 80% probability of a September hike to 1.25%, up sharply from about 23% before that July meeting.

The range-bound trading of the past two weeks reads as consolidation following a recovery from the 155.25–155.20 zone, the pair’s lowest level since early May. USD/JPY continues to hold above the 100-period simple moving average on the 4-hour chart, reinforcing the constructive technical picture.

• RSI near 57 and a slightly positive MACD both point to continued upside pressure rather than exhaustion.
• The pair’s next move depends partly on whether Himino and Warsh signal firm rate-hike intentions this week.

The Fibonacci Hurdle at 159.65

A decisive move higher requires clearing 159.63, the 50% Fibonacci retracement of the intervention-driven slide from the pair’s four-decade peak. That level has capped recent attempts and marks the line between consolidation and a fresh leg higher. Beyond it, the 61.8% retracement at 160.66 and the 78.6% level at 162.13 stand as the next reference points, with the recent swing high near 163.99 marking the broader ceiling for this move.

On the downside, initial support sits at the 100-period SMA near 158.90, reinforced by the 38.2% retracement at 158.60. A deeper pullback beyond that zone would expose the 23.6% level at 157.33, with the structural low near 155.27 marking the point where the recent uptrend would need to be reassessed entirely.

Support Levels Anchor the Uptrend

USD/JPY’s setup currently favors continuation, but the pair needs a confirmed close above 159.63, not just proximity to it, before a larger move can unfold. The stacked support at 158.90 and 158.60 gives the uptrend a clear technical floor, meaning a break of those levels would carry more weight than routine daily fluctuations.

This week’s central bank commentary will likely settle the question. A hawkish signal from Warsh at Jackson Hole would reinforce dollar strength and improve the odds of a clean break above 159.63, opening the path toward 160.66 and beyond. A more cautious tone from Warsh, paired with firm rate-hike signaling from Himino, would instead tilt the balance toward the yen and put the 158.90–158.60 support zone to an earlier test. Either outcome should resolve within days, given how closely both speeches are being watched.
