FX.co ★ Japan’s Tertiary Industry Slump Eases Sharply in May, Signaling Early Signs of Service-Sector Stabilization

Japan’s service-sector downturn eased significantly in May 2026, according to the latest Tertiary Industry Activity Index data released on 15 July 2026. The index improved to -1.40 in May, a notable rebound from the deep contraction of -11.10 recorded in April 2026.

While the indicator remains in negative territory, the sharp moderation in the rate of decline suggests that the worst of the recent slump in tertiary activity may have passed. The Tertiary Industry Activity Index is a key gauge of performance in Japan’s service industries, including retail, finance, transport, and communications, and is closely watched as a barometer of domestic demand.

The latest figures indicate that Japan’s service sector is still under pressure but may be moving toward a more stable footing after April’s steep fall. Market participants will be monitoring upcoming releases to see whether May’s improvement marks the beginning of a sustained recovery in the country’s crucial tertiary industries.
