Glossary

Every term between trade and settlement.

Settlement Finality Securities

The irrevocable transfer of legal ownership in a securities transaction — achieved through deterministic, conditional, or probabilistic finality depending on the settlement rail.

Settlement Instruction Automation

Automatically generating and transmitting settlement instructions to custodians and CSDs using pre-loaded SSI data — replacing manual entry, enabling STP, and making T+1 compliance operationally viable.

Stablecoin Capital Markets Infrastructure

The deployment of regulated, reserve-backed stablecoins as the continuous wholesale cash settlement layer for institutional capital markets — enabling 24/7 Delivery-versus-Payment and Payment-versus-Payment workflows.

Stablecoin Compliance: Broker-Dealer

The three-control-point AML framework for broker-dealer stablecoin operations — pre-broadcast screening, attributed value transfer via IVMS101, and post-settlement change-of-risk monitoring — built on the principle of attributed transparency.

Stablecoin Interoperability Standards (NIST IR 8408)

The NIST Interagency Report defining the federal technical taxonomy of stablecoin architectures — classifying reserve mechanisms, smart contract properties, and security vulnerabilities.

Stablecoin Run Risk vs Money Market Fund

The mechanics by which stablecoin peg pressure and money market fund redemption shocks propagate into systemic stress — compared across reserve structure, run trigger, and regulatory response.

Stablecoin Settlement

The use of regulated payment stablecoins as the cash leg in DvP securities settlement, enabling near-real-time finality on a 24/7/365 basis beyond Fedwire and CHIPS operating hours.

Standing Settlement Instructions

Pre-agreed instructions specifying how a counterparty's securities and cash should be delivered or received, applied automatically to every qualifying trade.

Straight-Through Processing (STP)

End-to-end automation of the post-trade lifecycle from execution to DvP settlement, with STP rate as the primary compliance KPI under T+1.
