FX.co ★ Japan’s Current Account Surplus Narrows Sharply in September 2026

Japan’s current account surplus declined significantly in September 2026, slipping to ¥2.372 trillion from ¥4.062 trillion in August 2026, according to the latest data updated on 9 November 2026. The non-seasonally adjusted figures highlight a marked month-on-month softening in Japan’s external balance.

The sharp narrowing of the surplus suggests a cooling in external income flows or a shift in the trade and services balance compared with August’s strong position. While Japan remains in surplus, the September data indicate a considerably weaker buffer from external accounts heading into the final quarter of 2026, a trend closely watched by investors assessing the country’s external resilience and currency dynamics.
