Collateral and security management is the operational register of assets pledged as security for credit exposures. It serves as the system of record for what assets back which loans, at what valuations, under what terms — providing the data that feeds the risk engine (MOD-030), the capital model (MOD-033), and the exposure calculations (MOD-084).

The module supports the full lifecycle of collateral: registration at origination (linking a property, vehicle, receivables pool, or personal guarantee to a facility), periodic revaluation (accepting updated appraisals and market values), monitoring (alerting when coverage falls below the loan-to-value covenant), and release (managing the discharge of security on repayment or substitution).

Customers with secured facilities can view their pledged assets, upload valuation reports, and track the release of security through the app. Credit staff use the back-office view to run the collateral register, process revaluations, and action coverage alerts. Required for SME lending, invoice finance, reverse mortgage, and any facility backed by real collateral.


Module dependencies

Depends on

Module Title Required? Contract Reason
MOD-028 Credit score & risk rating Required Collateral records are linked to credit exposures tracked by the credit risk rating engine.
MOD-033 RWA & capital ratio engine Optional Collateral valuations and haircuts feed the RWA and capital ratio engine as secured exposure inputs.
MOD-104 AWS shared infrastructure bootstrap Required AWS shared infrastructure provisioned by MOD-104 (EventBridge buses, S3, KMS, Kinesis, Cognito) is required before this module can be deployed.
MOD-103 Neon database platform bootstrap Required Neon database and schema provisioned by MOD-103 must exist before this module can read or write Postgres.

Policies satisfied

Policy Title Mode How
CRE-005 Concentration Risk Policy LOG Maintains the register of collateral supporting each exposure — used to calculate net exposure for concentration limit monitoring.
CRE-001 Credit Risk Management Policy CALC Feeds current collateral coverage ratios into credit risk monitoring so secured and unsecured exposure is correctly tracked.

Capabilities satisfied

Capability Title Mode How
CAP-100 Collateral registration AUTO Records pledged assets — property, receivables, guarantees — against the linked credit exposure with all identifying details.
CAP-101 Collateral valuation tracking CALC Accepts valuation updates, applies configured haircuts, and recalculates coverage ratios, feeding results to the exposure and capital engines.
CAP-102 Security release & enforcement GATE Enforces release of security only after full repayment or authorised partial release — blocks release without the required approval.
