WHY THIS INDICATOR MATTERS
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released monthly.
WHAT CHANGED THIS MONTH

WHAT'S NEXT
Sigmacast's 1-month forecast is 0.77% (latest print 0.7%). The projection is based on the indicator's own recent trend. This indicator correlates most strongly with BTC/USD (r=0.46) — a useful reference for crypto-focused traders.
