Philadelphia Fed Manufacturing Index
A monthly survey of manufacturing conditions in the Philadelphia Federal Reserve District, widely known as the Philly Fed Index.
Full explanation
The Philadelphia Fed Manufacturing Index is a monthly survey-based measure of business conditions at manufacturers in the Federal Reserve's Third District. It is commonly called the Philly Fed Index. The headline figure is a diffusion index: the share of firms reporting better general business activity minus the share reporting worse activity from the prior month. The survey also includes responses on orders, shipments, employment, inventories, delivery times, prices, and expectations.
Why traders watch it
It is an early monthly read on US manufacturing momentum, labor conditions, and price pressures. Because it is released before some broader national manufacturing data, traders may use it to reassess the near-term economic backdrop for US interest rates and the dollar.
Market interpretation
- USD
- Unexpected changes can influence views of US economic momentum and the interest-rate outlook, particularly when they align with or challenge other US data.
- US rates
- The result and its price and employment components can affect near-term expectations for growth, inflation, and monetary policy.
Stronger vs weaker outcomes
A reading stronger than expected may be viewed as evidence of firmer regional manufacturing conditions, while a weaker-than-expected reading may suggest softer conditions. Readings above zero indicate that more respondents reported improvement than deterioration, but the size of the surprise and the survey's components can matter more than the headline alone.
A higher reading generally means a larger net share of surveyed manufacturers reported improving general business activity versus the prior month.
A lower reading generally means a smaller net share reported improvement, or a larger net share reported deterioration.
Above zero means more firms reported improving than worsening conditions; below zero means the reverse.
Typical volatility
Moderate. This is a regional business survey rather than a direct measure of total US manufacturing output. It can be volatile from month to month, and its diffusion index measures the balance of reported changes, not the level of activity.
Trading considerations
- Compare the actual figure with the market consensus and the prior month's result.
- Check whether the new orders, shipments, employment, and prices measures confirm or contradict the headline.
- Allow for wider spreads and fast initial price reactions around scheduled US data releases.
- Treat the result as one regional signal and compare it with other manufacturing surveys and broader US economic releases.
