Glossary

Every term between trade and settlement.

Securities Lending Operations

The operational workflow that sources, manages, and recalls loaned securities — underpinning short selling and collateral financing through regulated locate and borrow processes governed by Regulation SHO Rule 203.

Securities Lending Settlement

The two-leg settlement lifecycle of a securities loan — FoP delivery of loaned securities, daily mark-to-market margining, and sese.034 recall return — managed as a continuous operational process across the relevant settlement infrastructure.

Securities Master Data

The operational discipline of maintaining a firm's golden copy — the single authoritative securities reference record kept current through daily vendor scrubbing, conflict resolution, and event-driven lifecycle enrichment.

Securities Operations Platform

Shared post-trade infrastructure that runs trade capture, enrichment, settlement, reconciliation, and compliance on a common primitive core — decoupling ops headcount from trade volume through platform-scale automation.

Securities Settlement Cycle

The end-to-end sequence from trade execution through clearing, affirmation, and DvP settlement — seven operational stages that must complete within the T+1 regulatory window.

Segregation of Duties (SoD)

Segregation of duties (SoD) is the internal control principle that no single operator can book, approve, and settle a transaction — enforced through conflict matrices, maker-checker workflows, and access certification reviews to satisfy SOX Section 404.

Settlement Finality Directive (SFD)

EU law making transfer orders in designated settlement systems legally final and irrevocable, protecting the financial system from participant insolvency contagion.

Settlement Finality DLT Blockchain

The point at which an on-chain transaction becomes irrevocable — a property of the consensus mechanism rather than a declaration by any central infrastructure operator.

Settlement Finality Legal Certainty

The statutory guarantee that a completed securities settlement is irrevocable and immune to insolvency court reversal — a protection that depends on designated system status, a precisely logged entry timestamp, and multi-jurisdictional legal alignment.
