NFIB Shows Main Street Cooled in August. The Credit Line Is the Part Worth Reading.

Every second Tuesday of the month, the National Federation of Independent Business publishes the Small Business Optimism Index. It's the longest-running read on how American small business owners actually feel about their own operations, quarterly since the fourth quarter of 1973, monthly since 1986, drawn from a random sample of NFIB's own membership.

That last detail matters. This is a survey of small business owners who belong to a small business advocacy group. It isn't a census, and it isn't bank data. What it is, reliably, is a monthly temperature check that has forty years of history behind it, which is why it moves markets on a Tuesday morning.

August came in at 98.7, down 1.1 points from July.

The trend, not the number

A single month means very little. The shape around it means a lot.

Optimism sat below the 52-year average of 98.0 for four consecutive months earlier this year. July broke that streak with the highest reading since August 2025. August gave back a little but stayed above the line, second month running.

So the honest read is a step back inside an uptrend, not a reversal. The Uncertainty Index tells a similar story: down 2 points to 89, which sounds like progress until you notice the historical average is 68. Owners are still planning with far less confidence than normal.

What got worse

Sales. A seasonally adjusted net negative 9% of owners reported higher sales over the prior three months, down 5 points from July and the weakest reading since November 2025. This is the number to watch.

Expectations. Owners expecting better business conditions fell 5 points to a net 10%, though that still sits above the long-run average of net 4%.

Inflation is back up. Reports of inflation as the single most important problem rose 2 points to 16%, now tied with taxes for second place among owners' top concerns.

What got better

Labor costs stopped being the problem. Reports of labor costs as the single most important problem dropped to their lowest level since March 2021, a five-year low. Labor quality also eased, though it remains far above its long-term average, and 82% of owners trying to hire still reported few or no qualified applicants.

Credit expectations improved. The net percent of owners expecting easier credit conditions rose 2 points to a seasonally adjusted net negative 2%, the highest level since December 2024.

Read that carefully. It's still negative, meaning more owners expect credit to get harder than easier. But it's the least negative it has been in twenty months, and it moved in the opposite direction from sales and expectations.

Business health held. Fifty-seven percent rated their business "good," up 2 points. Excellent slipped 3 points to 11%. Poor is 3%.

One month is noise. If September's sales reading falls again, this stops being a sentiment story and becomes a demand story, and Q4 origination planning should reflect it. The September survey publishes the second Tuesday of October.
