Japan’s services PMI flatlined at 50.0 in May as business costs surged to a 43-month high on Middle East war disruption, ending 13 months of sector expansion.
Summary:
Source: S&P Global Japan Services PMI, May 2026
- The headline Services Business Activity Index fell to 50.0 in May from 51.0 in April, ending a 13-month expansion streak; the composite Output Index slipped to 51.1 from 52.2, with growth driven solely by manufacturing
- Business input costs rose to the greatest extent in 43 months, driven by fuel, energy and raw materials price hikes linked to the Middle East war and supply chain disruption, alongside higher labour costs
- Output price inflation reached the second-fastest pace since the survey began in 2007, with the composite output charge measure hitting a fresh record high
- New order growth slipped to a 23-month low, with export business falling at the sharpest pace in over four years; consumer services posted the steepest contraction among all sub-sectors
- Employment grew at its slowest rate in nine months; business confidence remained below the post-pandemic average, weighed by geopolitical uncertainty, rising costs and demographic pressures
- S&P Global warned that manufacturing growth is partly a function of temporary stockbuilding expected to fade, and that the outlook hinges heavily on Middle East developments
Japan’s services sector stalled in May for the first time in over a year, as a near-record surge in business costs driven by the Middle East war collided with softening demand and squeezed activity to a standstill.
The S&P Global Japan Services PMI Business Activity Index fell to the neutral reading of 50.0 in May from 51.0 in April, ending a 13-month run of expansion. The broader composite Output Index, covering both manufacturing and services, slipped to 51.1 from 52.2, with all of the remaining growth attributable to manufacturing. Even that bright spot carried a caveat: S&P Global flagged that the manufacturing upturn is partly driven by temporary stock building that is expected to fade once inventories are deemed adequate, particularly if global economic conditions remain fragile.
The cost picture is the dominant story. Average input prices rose to their highest level in 43 months in May, with respondents consistently pointing to supplier price hikes tied to the Middle East conflict, fuel and energy costs, supply chain disruption and higher wages. The pressure fed directly into selling prices, with output charge inflation reaching the second-fastest pace since the survey began in 2007 and the composite measure hitting a fresh record high. Annabel Fiddes, Economics Associate Director at S&P Global Market Intelligence, described the price indicators as pointing to a near unprecedented increase in business costs.
On the demand side, new order growth slowed to a 23-month low, while export business fell at the sharpest pace in more than four years. Consumer services registered the steepest contraction of all sub-sectors monitored, consistent with household budgets coming under increasing strain from elevated prices. Employment growth slowed to its weakest in nine months.
The data compound an already difficult macro picture for Japan. A services sector that has now stalled, record output price inflation and a BOJ caught between competing signals make for an uncomfortable policy backdrop heading into the second half of the year.

The stagnation of Japan’s services sector puts the BOJ in an increasingly uncomfortable position: output price inflation hit a record high in May, which argues against further easing, but demand is softening and consumer services are already contracting, which argues against tightening. That stagflationary tension is difficult to resolve while the Hormuz disruption persists and supply chain costs keep rising. For the yen, a BOJ that is effectively pinned by conflicting signals is yet another headwind alongside the fiscal deficit expansion flagged in Tuesday’s supplementary budget
