What it means
Empire State Manufacturing Survey (NY Fed) and Philly Fed Manufacturing Survey are regional manufacturing PMI-equivalents released around the 15th-17th of each month. Provides early indication of national manufacturing trends that ISM Manufacturing PMI (released ~2 weeks later) will confirm or refute. Together they capture the Northeast manufacturing corridor, historically representative of broader US manufacturing trends.
Why it matters
Regional Fed surveys lead ISM Manufacturing PMI by 1-2 weeks. Strong Empire + strong Philly = high probability of strong ISM. Markets watch the combined regional reads for ISM expectations. Less reactive individually but informative as a directional indicator.
How to use it
Track both regional surveys mid-month for ISM Manufacturing PMI direction. Watch the New Orders and Prices Paid sub-indexes for forward signals. Average of Empire and Philly is the simple aggregate; some traders use a weighted-average against actual ISM history for the most accurate forecast.
