The Philadelphia Fed’s Manufacturing Business Outlook Survey just delivered the kind of number that makes economists do a double-take. The current general business activity diffusion index surged to 41.4, up from 10.3 the prior month, absolutely demolishing the consensus forecast of 13.
What the numbers actually say
The diffusion index measures the difference between the percentage of firms reporting increases in activity versus those reporting decreases. At 41.4, the math is lopsided in a way that’s hard to ignore: 53.1% of surveyed manufacturers reported an uptick in general business activity, while only 11.7% noted a decline.
New orders and shipments both contributed to the beat, suggesting the improvement isn’t just sentiment, it’s showing up in actual order books.
The survey covers manufacturers across the Third Federal Reserve District, which includes eastern Pennsylvania, southern New Jersey, and Delaware. It’s been conducted monthly since 1968, making it one of the longest-running regional manufacturing barometers in the country.
