ISM Manufacturing is the first major data point of every month and the classic business-cycle barometer: 50 is the expansion/contraction line. The prices-paid and new-orders subindices often move markets more than the headline: prices paid is an inflation tell, new orders leads the cycle. Deep sub-50 prints feed recession narratives fast.
How it moves Treasuries
A stronger ISM is bearish Treasuries; large downside misses trigger flight-to-quality bids. A hot prices-paid component can turn a soft headline into a bond-negative print. See it scored live on the Helious desk, or read how the standard-deviation surprise is computed.
