CptyStress

CptyStress is a web app (with optional desktop uploader) that helps risk teams run lightweight, defensible counterparty stress tests and concentration checks without building a full internal platform. Users ingest exposures from CSV/Excel or SFTP (trades, collateral, netting sets), map them to counterparties, then run scenario shocks (rates, FX, credit spreads, commodity moves) and simple wrong-way risk proxies. The app produces a board-ready pack: top counterparties by stressed exposure, liquidity/collateral impacts, limit breaches, and “what changed since last run.” It’s an AI + traditional app: AI assists with data mapping, entity matching, and narrative summaries, but calculations remain deterministic and auditable. This is not a replacement for enterprise risk engines; it’s a pragmatic layer that standardizes reporting and reduces manual spreadsheet chaos for mid-market firms and smaller banks.
