Large Exposures Limit Check (Basel III / Regulation YY)

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.

Single-node check aggregating each counterparty group's exposure against the Basel III / Regulation YY 25% (general) or 15% (GSIB-to-GSIB) single-counterparty limit, emitting a breach-list artifact.

Download the §4 chain definition artifact (hash-anchored composite JSON) or the §13.11 W3C Verifiable Credentials view. Both derive from the chain definition; no new hash is minted. Available after hash computation.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: The quarter-end exposure file is loaded. Does any connected group pass a quarter of our tier 1 capital?
Run the AINumbers MCP tool `run_chain` with {"chain":"large-exposures-check"} and read `art-425-large-exposures-limit-check.breach_list`.
Re-run with `inputs` for `art-425-large-exposures-limit-check`, reusing the values that result echoed, with `counterparties` changed so the cp-A term loan gross is 3000. 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.
