USD/JPY three-day rebound stalls at 158.55 confluence ahead of July NFP. A break below 157.95 could trigger a resumption of the yen's intervention-driven gains.
USD/JPY spent Thursday testing 158.55, a level that combines three technical markers: the former major ascending trendline from April 2025, the 38.2% Fibonacci retracement of the July 30 to August 3 decline, and the prior swing low from July 31. The pair touched an intraday high of 158.57 and closed at 158.46, after a three-day rally that recouped roughly half of the yen's gains from last week's joint US-Japan intervention.
The yen had fallen to a 40-year low of 163.99 on July 23. The Bank of Japan and the US Treasury intervened in a coordinated action on July 30 and July 31, pushing the pair down to 155.23 by August 3. The subsequent bounce lifted USD/JPY by 2.08% from that low to Thursday's close, giving back about half the intervention-driven move.
The monetary policy backdrop reinforces the technical picture. The 2-year UST-JGB yield spread widened from 2.12% to 2.82% during the yen's decline from mid-May to late July. The spread has since narrowed to 2.64%, reversing from just below the 3.02% resistance level. Kelvin Wong, senior global macro strategist at OANDA, said the narrowing supports the breakdown of USD/JPY from its former ascending trendline that held from April into May. A continued move lower in the spread toward 2.05% could revive yen strength, Wong added.
Wong identified a bearish flag pattern on the hourly chart. The price action formed lower highs after the initial drop from the July 30 high, resembling a dead-cat bounce. The hourly RSI showed bearish divergence while in overbought territory. Wong set the downside trigger at 157.95, the 200-day moving average. A break below that level could open the door to 157.30 and then 156.32. On the upside, an hourly close above 158.55 would invalidate the bearish view, exposing 159.45 as the next resistance.
Traders are now focused on the July non-farm payrolls report, due at 8:30 pm Singapore time (8:30 am ET). The consensus estimate calls for 80,000 jobs, up from 57,000 in June. A strong print would likely push US yields higher, widening the UST-JGB spread again and putting pressure on the yen. A miss would reinforce the narrowing spread and strengthen the case for a resumption of the yen's intervention-driven gains.
The 158.55 level is the immediate decision point. An hourly close above it would shift the near-term bias back to yen weakness. A break below 157.95 would confirm the bearish flag and target the 157.30 and 156.32 supports. The NFP number will determine which side of that inflection the market tests first.
