WHY THIS INDICATOR MATTERS
This release contributes to the broader macro picture used by cross-asset investors for positioning and risk management. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Aug 2026): actual 0.2 %, consensus 0.3 %. Prior reading (Jul 2026): -0.4 %. Before that (May 2026): 0.8 %.
WHAT'S NEXT
