USD/JPY’s sharp two-day decline has erased its August gains, while hawkish BoJ signals and a bearish Head & Shoulders pattern raise the risk of further downside.
Key takeaways
- JPY strength accelerated sharply last week, with USD/JPY falling 0.92% on 2 September and another 1.84% on 3 September to close at 155.80.
- Fundamental risks have shifted towards a stronger yen, supported by Bessent’s remarks, Takata’s hawkish BoJ stance and heightened FX intervention risk.
- USD/JPY’s 155.03 neckline is the potential key bearish trigger. A breakdown may expose 153.75 and 152.55/151.90, while 158.50 is the pivotal resistance.
In the past week, the Japanese yen has strengthened dramatically against the US dollar, a trend that began on Wednesday, 2 September 2026, when USD/JPY declined by 0.92% and extended its losses by 1.84% on Thursday, 3 September 2026, to close at a one-month low of 155.80, these 2 sessions wiped out the prior gains of the USD/JPY from 3 August 2026 low to 2 September 2026 high (see Fig. 1).

Last week’s swift decline in USD/JPY smells like FX intervention, with no clear catalyst in relevant economic data releases.
However, so far, there are no official press releases from Japan or the US confirming any form of intervention, and no “according to sources” reporting from media outlets.
What we know so far
Here are the three fundamental developments to reinforce the current bout of JPY strength:
- US Treasury Secretary Scott Bessent expressed support for decisive Japanese action to address yen weakness to Bank of Japan (BoJ) Governor Ueda during the G-20 finance and central bank leaders meeting, according to a readout released by the US Treasury Department on Tuesday, 1 September 2026. This reduces the political constraint on further BoJ tightening and suggests Washington is increasingly comfortable with a stronger yen.1
- BOJ board member Hajime Takata said policymakers should consider options beyond the conventional 25-basis-point rate increase, including larger or consecutive hikes, said in a news conference on Wednesday, 2 September 2026. While Takata remains one of the BoJ’s most hawkish members, his comments increase the risk that the central bank accelerates its tightening cycle.2
- The speed of the yen’s appreciation placed traders on high alert for another round of intervention. Although there was no immediate confirmation of official yen buying, the threat of action creates an increasingly asymmetric risk around the psychologically important 160.00 region.
Let’s now unpack the USDJPY from a technical analysis perspective on a medium-term (multi-week) horizon.
Impending bearish reversal configuration below 200-day MA

The USD/JPY has formed two significant bearish technical patterns.
Firstly, since the start of the multi-month up move from the 27 January 2026 low of 152.09 to the 40-year high of 164.00 on 23 July 2026, the USD/JPY has formed a potential medium-term bearish reversal “Head & Shoulders” configuration below 160.40 (after 2 September and 3 September 2026 rapid sell-off) with the neckline support coming in at 155.03 (see Fig. 2).
Secondly, prior to last week’s sell-off, USD/JPY staged a bearish reaction on 2 September 2026, right after a retest of the 160.40 pull-back resistance of the former major ascending trendline support from the 22 April 2025 low and broke below the 200-day moving average.
These observations increase the odds of a medium-term bearish breakdown on the USD/JPY.
Watch the 158.50 key medium-term pivotal resistance (also the 200-day moving average) of the USD/JPY, and a break below the 155.03 intermediate support (the neckline of the “Head & Shoulders”) may expose the medium-term supports at 153.75 and 152.55/151.90 (also Fibonacci extensions) (see Fig. 3).
However, a clearance and a daily close above 158.50 would invalidate the bearish scenario, with the next medium-term resistances coming in at 159.70 and 160.50/161.00 (also the 50-day moving average).
