Key Takeaways

1.The current 2026 JPY appreciation is driven by structural shifts rather than transient positioning, as traditional carry dynamics deteriorate and the US-Japan 10-year yield differential narrows to ~209 bps.
2.Japanese overseas capital allocation has slowed sharply, with rolling 52-week net foreign asset purchases falling to new lows, eroding key fundamental support for USD/JPY.
3.Bank of Japan policy normalization is credible and active, having raised its policy rate to 1.25% in September 2026 (the highest since 1995), with markets pricing a 72% probability of another hike in December to 1.45%.
