Step 1 · Trade Capture (Post-Trade Handoff)Policy-EnforcedBlockchain-Native
The trade ticket arriving at the back office — the front office (Securities rail) has already executed, now post-trade processing begins.
**Cross-rail reference: Stages 1-4 fired on the Securities Trading rail.** The trade has already been executed — identity verified, price discovered, terms negotiated. This path begins at the post-trade handoff. The trade is captured in DTCC's Trade Information Warehouse. L5 Application lit only — the handoff is a recordkeeping event. All earlier compliance gates were satisfied on the originating rail.
Step 2 · NSCC Novation & Netting (CNS)Code-EnforcedBlockchain-Native
The clearing house stepping between buyer and seller — NSCC becomes the buyer to every seller and the seller to every buyer. Netting reduces gross obligations by ~98%.
NSCC novates the trade: it becomes the central counterparty to both sides. CNS (Continuous Net Settlement) nets all trades per security per participant, reducing gross settlement obligations by approximately 98%. L2+L3 lit: consensus (multilateral netting) and execution (novation logic) operate below the enforcement line. D9 (prudential) is primary — NSCC's risk management framework (margin requirements, clearing fund contributions) is the systemic risk control.
Step 3 · Margin & Risk ManagementCode-EnforcedBlockchain-Native
A futures exchange margin call — participants must post collateral proportional to their risk exposure, or face position liquidation.
NSCC calculates margin requirements via its NSCC Rules and VaR-based risk model. Clearing members post margin (cash, Treasuries, eligible securities) to NSCC's Clearing Fund. If a member defaults, the Clearing Fund and NSCC's loss allocation waterfall absorb losses. L3 Execution lit: margin calculations and risk monitoring are code-enforced at the CCP level. This is the compliance center of gravity — NSCC's risk framework is what makes T+1 settlement systemically safe.
Step 4 · T+1 Settlement (DTC Book-Entry)Code-EnforcedBlockchain-Native
The Federal Reserve's Fedwire Securities Service — book-entry transfer of securities with simultaneous payment, but at DTCC it happens one business day after trade.
Settlement occurs T+1 via DTC's book-entry system. Securities move as book entries on DTC's ledger; cash moves through the Federal Reserve's National Settlement Service. DvP is enforced — securities and cash move simultaneously. L1+L2+L3 lit — the full stack below the enforcement line. If settlement fails (insufficient securities or cash), the fail enters NSCC's fail management process with penalty charges (SEC Rule 204).
Step 5 · Fail Management & ReportingPolicy-EnforcedBlockchain-Native
The back office's end-of-day reconciliation — fails identified, buy-in notices issued, regulatory reports filed.
Settlement is final — or a fail is recorded. Failed settlements trigger SEC Rule 204 close-out requirements (buy-in within specified timeframes). NSCC tracks fails and can force close-outs. L5 Application lit only. Regulatory reporting (FINRA TRACE, CAT) captures the full trade lifecycle. **Structural note:** the T+1 compression (from T+2, effective May 2024) reduced but did not eliminate settlement fails. The Post-Trade rail exists because finality is never guaranteed — it must be managed.
