MACHINE ECONOMY INDEX · MEI

The Machine Economy Index

A composite 0–100 health score for the machine economy — the geometric mean of four components, recomputed every day from normalized rail metrics and the Legal Rail Readiness Score.

7-DAY CHANGE

Tap any component to open its live metrics in the Data dashboard.

An arrow means the component's direction over 7 days holds in at least 90% of the methodology's sensitivity draws (Legal: under all three of its category weightings — rank-sum, equal and rank-order-centroid). Otherwise both values are shown and no direction is claimed. Legal links to the LRRS breakdown below.

HOW THE INDEX IS BUILT

Four components, weighted equally — combined as a geometric mean.

Each component scores on a 1–100 scale. The geometric mean sits at or below the simple average — and the weaker the worst component, the harder it pulls the whole index down.

PAYMENTPHYSICALLEGALMACRO

The MEI is an equal-weighted geometric mean across four components (three rails plus realized demand). Each component is normalized from its constituent metrics on a 1–100 scale. See the Methodology for the full derivation.

ON BEING OPINIONATED

A reference index is a set of deliberate, published choices — not a claim to be above judgment.

The MEI is transparently opinionated — like every major reference index, its metric selection, normalization bounds, and aggregation rules are deliberate editorial choices, published in full and versioned when changed. Credibility comes from consistency and transparency, not from pretending to be above judgment.
