The U.S. transition to T+1 settlement on May 28, 2024, shortened the standard settlement cycle for most securities transactions from two business days to one, delivering measurable efficiency gains across financial markets. Clearing fund requirements declined by an estimated $3.7 billion compared with the previous quarter's average, while trade affirmation improved significantly, with approximately 94.55% of transactions affirmed by 9 p.m. ET on trade date by May 29, 2024, up from 73% at the end of January 2024.
Faster settlement reduces the period during which clearing agencies and market participants remain exposed to unsettled transactions, lowering counterparty exposure and reducing the amount of capital firms need to maintain against outstanding obligations.
Europe Faces Growing Failed Trade Problem
Europe's post-trade infrastructure faces mounting challenges as firms prepare for the October 2027 transition. Settlement activity increased 15% in 2025, but failed trades grew 21% over the same period, indicating that operational exceptions are increasing faster than transaction volumes.
An industry assessment found that only 33% of European middle offices had automated the storage and exchange of Standing Settlement Instructions (SSIs), while 68% continued to rely on some manual trade-matching processes. These manual processes become increasingly difficult to manage under T+1, as firms will have less time to identify mismatched instructions and resolve allocation discrepancies.
Securities Lending and FX Funding Under Pressure
Securities lending and foreign exchange funding remain significant operational pressure points. A 2024 industry survey covering nearly 500 institutions found that half of respondents reported T+1 had affected their securities-lending operations, up from 33% in the previous year's survey. Among sell-side firms, 56% reported significant disruption to lending and recall activity.
Foreign exchange funding creates a related timing challenge for cross-border transactions. Firms settling international deals must arrange currency conversion and cash availability within a compressed window, requiring earlier funding decisions and better counterparty coordination.
Partial Settlement and Infrastructure Solutions
The Depository Trust Company (DTC) is developing an Automated Partial Settlement solution designed to reduce failed transactions by allowing available securities to settle while outstanding quantities remain pending. Client testing was scheduled for Q3 2026, with production targeted for Q3 2027 subject to regulatory review and approval. A second phase covering bilateral securities-finance transactions is targeted for Q4 2028.
Europe's regulatory framework was confirmed as complete on October 16, 2026. The first major compliance milestone arrives on December 7, 2026, when applicable allocation and confirmation processes must use standardized electronic communication channels and machine-readable methods. The European Central Bank has outlined changes to the night-time settlement process on TARGET2-Securities (T2S), planned for June 2027.
Key Areas Requiring Improvement
Four areas require particular attention before the next settlement shift:
- Automated trade matching to reduce manual processing in allocations, confirmations and settlement-instruction management
- Securities availability improvements across securities lending, recalls and inventory management
- Liquidity and FX funding alignment with shorter settlement windows for cross-border transactions
- Expansion of automated partial-delivery capabilities and improved system interoperability
The success of T+1 will depend not just on how quickly trades settle, but on how efficiently the financial system moves securities and capital from execution to final delivery.
