U.S. Business Activity Accelerates as Inflation Pressures Build

A preliminary September survey showed U.S. private-sector activity at its strongest pace in more than five years, with new orders rising across services and manufacturing. The same report found worsening supply delays, growing backlogs, hiring difficulties, and higher input costs—an uncomfortable combination for businesses, consumers, and Federal Reserve policymakers.

Growth strengthens across the private sector

U.S. business activity expanded at its fastest pace since July 2021, according to S&P Global’s preliminary September purchasing managers survey. The composite output index rose to 58.4 from 56.0 in August. Readings above 50 indicate expansion, and the increase reflected gains in both manufacturing and services rather than strength confined to one part of the economy.

New orders climbed to their highest level since March 2022, while unfinished work reached its highest point since May of that year. S&P Global said the survey was consistent with annualized economic growth of about 5 percent. The Atlanta Federal Reserve’s separate tracking estimate has also pointed to growth above 5 percent, although such real-time estimates change as new data arrive.

Capacity limits complicate the good news

Strong demand is usually welcome, but this report also shows businesses struggling to meet it. Supplier delivery times lengthened, backlogs accumulated, and companies reported difficulty finding suitable workers. Input-price pressures reached their strongest level in nearly four years. Supply disruptions associated with the U.S.-Israeli war with Iran have added to those constraints through energy, shipping, and materials costs.

When orders rise faster than capacity, firms gain more ability to increase prices. Some may invest in equipment, hire employees, or reorganize production, but those responses take time. In the interim, customers can face longer waits and higher bills. The balance between expanding capacity and simply passing on costs will help determine whether the growth remains durable.

The Federal Reserve receives a mixed signal

For monetary policymakers, the combination is difficult. Rapid activity and stronger pricing power can argue for higher interest rates, especially if inflation expectations begin to rise. At the same time, part of the pressure comes from supply shocks that borrowing costs cannot quickly fix. Raising rates may restrain demand, but it cannot reopen shipping routes or produce skilled workers overnight.

The survey is also not a final government measure of output or inflation. It captures what participating companies report during the month and can provide an early signal before official data are available. Policymakers will compare it with employment, consumer prices, spending, wages, and revised gross domestic product figures before reaching conclusions about the economy’s direction.

What households and businesses should watch

The practical questions are whether wage gains keep pace with essential costs, whether employers can fill openings, and whether supply delays begin to ease. Small businesses may be especially sensitive because they often have less bargaining power with suppliers and fewer options for absorbing unexpected expenses. Households may feel the effects through food, fuel, travel, and goods that depend on international transportation.

A single strong month does not guarantee a sustained boom, just as one price measure does not establish a new inflation trend. The next several reports will show whether orders translate into completed production and whether increased hiring and investment expand capacity. For now, the economy appears to be growing quickly while encountering limits that could make that growth more expensive. That tension will shape corporate planning, federal policy, and family budgets through the autumn.
