The U.S. Services and Manufacturing activity just came in weaker than expected. December's S&P Global Composite PMI landed at 52.7, falling short of both the previous month's 53.0 and the consensus estimate of 53.0.

Here's what this means for the broader market: PMI readings above 50 signal economic expansion, but the miss suggests cooling momentum heading into year-end. For crypto traders, this matters because risk-on sentiment typically follows economic optimism. When these macro indicators soften, investors often rotate toward defensive plays, which can pressure volatile assets like Bitcoin and altcoins.

The deceleration in composite activity—combining both services and manufacturing—points to potential headwinds in Q1. Keep an eye on how central banks interpret this data; it could influence interest rate expectations and overall risk appetite in the months ahead.
