How to read this timeline
What a month card shows. The big number is the monthly average of the Supply Chain Risk Index — every day of the month added up and divided, nothing smoothed. Under it: the zone that average falls in, the lowest and highest daily score, and how the month compared with the one before.
Where this record stands. The Supply Chain Risk has been running since April 2026. Its strongest month so far was May 2026 at 57.4; its calmest was September 2026 at 36.3 — a spread of 21.1 points. Compared with its first month it is now lower by 19.5.
Why the month pages matter. An average hides the story. Each month page lists the biggest daily moves and the headlines that caused them, plus what eased the pressure. That is how you tell a one-day shock from a real shift.
Locked and open. Closed months are locked the day they end and never rewritten. The current month refreshes every night until it closes, so its card can still move.
