Regenerative Surplus Index and Gross Regeneration Surplus: Measurement of abundance circulation, from the lot to the national satellite

This white paper specifies two interoperable metrics of regenerative economics: the Regenerative Surplus Index (RSI) and Gross Regeneration Surplus (GRS). The index is the real-time composite of regenerative performance for a bounded system. Surplus is the period aggregate of regenerative wealth. Together they move the unit of account from monetary throughput to net regenerative surplus — vitality, resilience, optionality and liberated time — after irreversible gains and losses. The canonical index, as in the master measurement framework, is RSIt = α ∆Vt + β ∆Rt + γ ∆Ot + δ ∆Tlib,t. The canonical surplus is GRSt = [RSIt − RSIt−1] + Girr − Lirr. A corridor form scales the index change by extent and a declared ecological multiplier so that a national satellite and a lot note do not share a unit by accident. Premium, dividend pool and own-margin are derived quantities. They are not the index and they are not surplus. The argument is one path. Section 1 states why gross domestic product cannot see regeneration. Section 2 reviews the measurement literatures. Section 3 gives the definitions and the standard modal representation. Sections 4 and 5 derive the index and the surplus. Section 6 separates price, pool and wealth. Section 7 places computation on the Universal Market Ecosystem Infrastructure, specified as Sovereign, Utility and Space-Data stacks. Section 8 applies the same recognition rules to aquaculture, agriculture, mining and logistics, keeping sixty-six months of field mapping apart from modelled sketches. Section 9 draws the policy import. Section 10 records status. The metrics are public domain. As at September 2026 no audited surplus has been published.
