WHY THIS INDICATOR MATTERS
This release contributes to the broader macro picture used by cross-asset investors for positioning and risk management. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released monthly.

WHAT'S NEXT
Sigmacast's 1-month forecast points to a similar reading versus the latest print, with the 3-month outlook reinforcing that direction. Both horizons are aligned bearish for this indicator, suggesting a consistent trend signal. Trend-driven dynamics are the primary headwind in the current projection. This indicator correlates most strongly with XAU/USD (Bearish XAU, r=-0.59) — a useful reference for commodities-focused traders.
