U.S. manufacturing activity accelerated in October, with the Institute for Supply Management's purchasing managers' index rising to 55.5 from 54.5 in September, according to figures released Monday. The improvement extended the sector's expansion while factories continued to report rising input costs, adding to evidence of an economy growing without a clear resolution of its inflation problem.

The Nov. 2 ISM report showed its production index climbing to 59 from 56.7. Its prices index fell to 75.2 from 77.9, indicating that cost increases remained widespread despite easing. Neither reading represents a percentage change in the volume of output or the prices businesses pay.

The release exceeded economists' expectations for an unchanged headline index, Reuters reported. It gives businesses and policymakers a fresh view of factory conditions after last week's government reports showed stronger quarterly growth and persistent consumer inflation. Those measures cover different periods and parts of the economy, so their signals require careful comparison.

A stronger survey, with limits

ISM's index summarizes month-to-month changes reported by supply executives. Readings above 50 generally indicate manufacturing expansion. The headline combines new orders, production, employment, supplier deliveries and inventories with equal weights. It measures the direction and breadth of change rather than providing a census of goods produced.

Reuters reported that new orders increased modestly and supplier deliveries slowed further. Employment continued expanding at a slightly slower pace. Together, those details point to continued demand and operating pressure rather than an uncomplicated improvement in every aspect of factory performance. A stronger headline does not establish that every manufacturer is hiring or that cost pressures have disappeared.

Measured output provides a separate check

The Federal Reserve's latest production release, published Oct. 16, showed manufacturing output increasing 0.3% in September after declining 0.2% in August. Manufacturing production was 1.1% above its year-earlier level. Unlike the purchasing managers' survey, these statistics estimate changes in actual output, making them a complementary measure of the industry's performance.

Total industrial production rose a larger 0.7% in September, but that broader measure also includes mining and utilities. Utilities output jumped 3.5%, illustrating why industrial production and manufacturing cannot be treated as interchangeable. Manufacturing capacity utilization stood at 75.9%, below its 78.2% long-run average. That aggregate spare capacity can coexist with delivery delays affecting particular materials or suppliers; the national utilization figure does not identify where individual bottlenecks occur.

Domestic spending supports the expansion

The Bureau of Economic Analysis's Oct. 29 GDP estimate showed inflation-adjusted output growing at a 3.4% annualized rate in the third quarter, up from 2.2% in the second. Investment, consumer spending and government spending contributed to growth, while exports declined. The investment increase included inventory accumulation and equipment spending, with computers and related equipment leading the equipment gain.

A separate measure of private domestic demand, combining consumer spending and fixed investment, grew at a 4.9% annualized rate. That helps explain why businesses can encounter strong orders even when some overseas markets are less supportive. The figures describe July through September, however, while Monday's factory survey covers October. The GDP report is also an advance estimate subject to revision, not a final measure of how the economy entered the fourth quarter. BEA put actual quarter-to-quarter GDP growth at 0.8%; the annualized rate expresses that pace as if it continued for a year.

Higher spending does not mean equal gains in buying power

BEA's separate September report showed consumer spending rising 0.5% in current dollars, but less than 0.1% after inflation. Personal income increased 0.2%, while inflation-adjusted disposable income fell 0.3%. Those differences qualify the picture of resilient demand: households spent more dollars without a comparable monthly increase in the quantity of goods and services purchased.

The personal consumption expenditures price index increased 0.5% during September and 3.6% from a year earlier. Excluding food and energy, prices rose 3.1% annually. These are consumer-price measures, distinct from ISM's factory input-price index. A decline in the latter can signal less widespread purchasing pressure without proving that household inflation has fallen or that manufacturers have reversed earlier price increases. BEA also reported a personal saving rate of 3.8%, measuring saving as a share of disposable income.

The Fed is still waiting for clearer evidence

The Federal Reserve's Oct. 28 policy statement maintained its benchmark rate range at 3.75%–4% by a 10–2 vote. Officials described strong economic activity, resilient domestic spending and robust investment, while saying inflation remained elevated. Lisa Cook and Beth Hammack dissented because they preferred a quarter-point increase.

The committee said additional information would help determine the policy needed to return inflation to its 2% goal. Its statement committed to price stability without announcing a date or direction for the next rate change. Monday's survey adds evidence of continued factory expansion, but does not itself settle the interest-rate decision. The practical question is whether subsequent production, spending and price reports show demand being met with more output and easing inflation, rather than continued pressure on costs.
