The USD/JPY reference rate surged to 157.888 on 2026-09-18, rising 1.41% in one day and 2.50% over five days, pushing it well above both the 5-day average of 155.637 and the 20-day average of 156.848. This sharp rebound follows a steep decline from early-September highs near 160.16 to a low of 153.27 on 2026-09-09, suggesting the recent dollar strength may be a corrective rally within a broader consolidation rather than sustainable momentum. Given the proximity to prior resistance and the speed of the advance, mean-reversion pressure could emerge for the assessment date of 2026-09-21.

What could change the view. The FOMC meeting concluded on 2026-09-16 with accompanying economic projections, and any hawkish interpretation not yet fully priced could extend dollar strength. Past declines do not guarantee reversal.

The view was generated with Workers AI and checked against these sources. Cross-rates,
percentage changes and averages are calculated by fx.reviews from ECB observations. The
underlying reference data is freely available.
Assessment: the ECB reference observation on 21 Sept 2026. A move
within ±0.01% is flat. A missing observation stays unverified
rather than being replaced by a later price.
