Japan’s adjusted current account surplus shrank markedly in September 2026, signaling a cooling in external balances after a strong performance in the prior month. According to data updated on 9 November 2026, the surplus fell to 1.82 trillion yen in September, down from 2.98 trillion yen in August 2026.
The decline suggests a significant month-on-month softening in Japan’s external position over the transition from late summer into early autumn. While details behind the shift—such as trade flows or income balances—were not disclosed, the move from 2.98 trillion to 1.82 trillion yen may prompt closer scrutiny from market participants tracking Japan’s external resilience and its implications for currency dynamics and broader economic momentum.
