# Why Japanese Yen (JPY) fell 1.07% on September 25, 2026

Japanese Yen (JPY) fell 1.07% on September 25, 2026 — Month-end flows fuel yen selling pressure.

## What happened

Month-end foreign exchange flows favored dollar and euro buying over yen and pound selling, as noted by BofA's flow analysis.

## Why it moved

Quarter- or month-end rebalancing typically sees yen liquidation as portfolios reduce safe-haven hedges and reallocate into higher-yielding or growth-linked assets; this structural selling pressure weakens USD/JPY.

## Why it matters

Part of the Japan (Yen & Equities) theme; yen weakness aligns with the equity rally, as lower rates and weaker currency support exporter margins and capital repatriation.

## What would break the thesis

If risk sentiment deteriorates sharply or Bank of Japan signals imminent tightening, month-end flows could reverse and safe-haven demand could push yen higher again.
