• The ISM manufacturing index for April was unchanged at 52.7, missing the consensus estimate of 53.2 but remaining in expansion territory.
  • The prices paid sub-index surged to 84.6, the highest since April 2022, signaling persistent cost inflation.
  • The data suggests a challenging environment for manufacturers: steady output growth alongside rising input costs that could squeeze margins.

The Institute for Supply Management’s manufacturing PMI came in at 52.7 for April, unchanged from March and below economists’ expectations of 53.2, according to people familiar with the survey. While the reading still indicates expansion—any number above 50 signals growth—the flat print amid elevated price pressures has caught the attention of market participants.

More striking was the prices paid index, which jumped to 84.6 from 83.1 in March, marking the highest level in two years. The surge reflects ongoing cost pressures from tariffs, energy, and supply chain frictions, according to analysts. “Input costs are clearly rising faster than output prices, which will test manufacturers’ pricing power,” one industry observer noted.

Mixed Signals

The combination of modest growth and rising costs presents a dilemma for the Federal Reserve, which is weighing inflation risks against a still-expanding economy. “This report reinforces the case for patience on rate cuts,” said a fixed-income strategist at a major bank. “The Fed will want to see sustained evidence that price pressures are easing before easing policy.”

Survey responses from manufacturers highlighted uneven demand across sectors. Some firms reported robust new orders while others faced headwinds from higher raw material costs and longer supplier delivery times. “It’s a tale of two economies out there,” one purchasing manager commented.

Market Reaction

Treasury yields edged higher following the release, with the 10-year note rising 3 basis points to 4.68%, as traders pared bets on near-term rate cuts. The S&P 500 dipped 0.2% in early trading as the data added to uncertainty about the economic outlook.

“The market is trying to digest what this means for inflation,” a portfolio manager at a large asset management firm said. “If input costs keep rising, it could eventually stoke consumer prices and delay the Fed’s pivot.”

Looking Ahead

The ISM report follows other recent data showing sticky inflation and resilient consumer spending. Investors will now focus on the services PMI and the monthly jobs report due later this week for further clues on the economy’s path.

A separate release from S&P Global showed its manufacturing PMI for April came in at 52.9, slightly above the preliminary estimate of 52.8, confirming the expansionary trend.
