ISM Manufacturing Index Shows Broad-Based Improvement in May

  • The ISM Manufacturing Index rose 1.3 points to 54.0 in May – its highest level since mid-2022 – signaling a fifth consecutive month of expansion and a clear re-acceleration in factory activity. 
  • Growth remained broad-based across components, with only 2% of manufacturing GDP now in contraction, compared to 19% in April.
  • Demand conditions strengthened notably. New orders posted the largest gain, rising 2.7 points to 56.8, while export orders rebounded back into expansion (50.6). Production also firmed (+0.9 to 54.3), pointing to a clear pickup in output momentum. 
  • Employment improved meaningfully but remains in contraction. The employment index rose 2.2 points to 48.6, a notable rebound from April but still below the 50 threshold, indicating ongoing (but moderating) labor market softness.
  • Trade-related indicators turned more supportive. Exports returned to expansion (+2.7 to 50.6) and imports strengthened (+2.7 to 53.0), suggesting firmer external and domestic demand flows.
  • Price pressures eased modestly but remain extremely elevated. The prices-paid index fell 2.5 points to 82.1, marking a second consecutive month above 80. Supplier deliveries stayed slow (60.6, unchanged), highlighting ongoing supply-side constraints despite some improvement in cost momentum.
  • Survey respondents' commentary remained cautious despite the improvement in activity. Firms continued to highlight elevated cost pressures and supply disruptions, with respondents noting ongoing volatility in energy-linked inputs and uncertainty tied to geopolitical developments. Comments included observations that prices "continue to rise for many products,” that “supply constraints continue to propagate,” and that “current atmosphere is one of extreme uncertainty and concern for the future in terms of both price stability and longer-term supply continuity".

Key Implications

  • The May report points to a meaningful improvement in underlying manufacturing momentum, with the broad-based pickup in new orders, production and trade flows signaling firmer demand conditions both domestically and externally. The rise in the headline PMI to a multi-year high, alongside gains in backlogs and inventories and a smaller share of activity in contraction, suggests that the sector is transitioning from a fragile recovery to a more durable expansion phase.
  • At the same time, the report reinforces that inflation pressures remain a major challenge. While the moderation in the prices index is a step in the right direction, its still-elevated level above 80, combined with persistently slow supplier deliveries, underscores that input cost pressures and supply-side frictions are a drag on manufacturing activity. This suggests that firms will continue to face margin compression and planning uncertainty, particularly in energy-and materials-intensive industries. As a result, even with improving activity, the persistence of elevated cost pressures is likely to constrain the pace of expansion and keep policymakers cautious, limiting the scope for near-term monetary policy easing.
