Multilateral Netting Settlement

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Linear two-step chain for in-house-bank (IHB) settlement cycles. Step 1 computes N-entity corporate cash netting: gross inter-company positions to net positions to minimum settlement legs using a greedy matching algorithm per BIS CPMI net settlement framework (2012). Reports wire-count savings and netting efficiency. Netting statement is suitable for anchor_batch Merkle-leaf receipts. Step 2 allocates overnight IHB interest on the net settlement balances per OECD Transfer Pricing Guidelines 2022 Chapter X arm’s-length rate, with ACT/360 day-count and per-member withholding tax deduction. NOT FICC clearing margin netting. No personal data is processed.

Multilateral Cash Netting art-259-compute-multilateral-netting

Computes N-entity gross inter-company positions to net positions to minimum settlement legs using the BIS CPMI greedy matching algorithm. Emits entity_net_positions[], settlement_legs[], wire_count_savings, netting_efficiency_pct, and gross_volume/net_volume. Netting statement suitable for anchor_batch Merkle-leaf receipts (cry-04). NOT FICC clearing margin netting — corporate cash netting only.

In-House Bank Interest Allocation art-260-allocate-ihb-interest

Allocates overnight IHB interest on the net settlement balances from Step 1. Notional pooling (pro-rata on pool net) or ZBA sweep. ACT/360 day-count. Per-member withholding tax deduction. OECD TP Guidelines 2022 Chapter X arm’s-length rate. Returns per-member gross_interest, withholding_amount, net_interest, and total_interest_allocated. Final stage.

Question: Under a single master agreement, how much settlement volume does multilateral netting remove across these positions? Run the AINumbers MCP tool `run_chain` with {"chain":"multilateral-netting-settlement"} and read `art-259-compute-multilateral-netting.netting_efficiency_pct`. Re-run with `inputs` for `art-259-compute-multilateral-netting`, reusing the values that result echoed, with `gross_positions` changed so ENTITY A pays only 100 instead of 1000. Compare the same field. Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`. Ledger, for a human re-check: https://ledger.ainumbers.co/ PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
