Economists expected the Philadelphia Fed’s factory gauge to fall by nearly half this month. It hit a five-year high instead.

The Federal Reserve Bank of Philadelphia said Thursday that its diffusion index for current general activity rose to 47.4 in August from 41.4 in July, the strongest reading since April 2021.

The economist consensus had called for a decline to 25.0.

Nearly 57% of firms reported an increase in activity against 10% reporting a decrease.

The forward-looking number was the larger surprise.

The index for future general activity climbed 39 points to 73.6, its highest reading since August 1983.

“Most future indicators jumped higher this month, suggesting widespread expectations for overall growth over the next six months,” the report said.
