FX.co ★ Japan’s Manufacturing Momentum Eases as S&P Global PMI Slips to 54.1 in September

Japan’s manufacturing sector showed a slight loss of momentum in September, as the S&P Global Manufacturing PMI eased to 54.1, down from 54.9 in August 2026.

While the latest figure, updated on 24 September 2026, still signals solid expansion in factory activity — remaining comfortably above the 50.0 threshold that separates growth from contraction — the dip suggests the pace of growth is moderating. The softening from August’s 54.9 reading indicates that, although demand and production likely remain robust, the recent surge in manufacturing activity may be past its peak.

The September reading will be closely watched by market participants and policymakers as they assess whether this cooling is a temporary pause after strong gains or the beginning of a more sustained slowdown in Japan’s industrial recovery.
