Goldman Sachs has begun using EquiLend 1Source, a distributed ledger technology (DLT) platform designed to streamline securities lending and financing transactions. The investment bank joins BNY and National Bank of Canada on the platform, which aims to reduce transaction discrepancies, limit manual reconciliations and improve the accuracy of securities finance records. The adoption highlights how financial institutions are applying shared digital ledgers to the operational processes behind large-scale capital markets.

A Shared Ledger for Securities Lending

Securities finance involves the lending and borrowing of stocks, bonds and other financial instruments, often to support short selling, market-making and portfolio management. These transactions generate a stream of updates, including changes to rates, returns, recalls and other contract details.

When lenders and borrowers maintain separate records, differences can emerge as transaction terms change. Firms must then investigate and resolve these reconciliation breaks, consuming operations staff time and potentially contributing to settlement failures or incorrect accruals.

EquiLend’s 1Source is designed to address that problem at the source. Rather than relying solely on separate records that must be compared afterward, the platform maintains a shared digital ledger for transaction lifecycle information. It runs on the Canton Network, a distributed ledger designed for institutional financial applications. Equilend+2

The goal is to give both sides of a transaction access to consistent information as agreed terms and lifecycle events change. EquiLend says this can reduce manual reconciliation, duplicate technology costs and errors that affect settlement and profitability. Those benefits depend on counterparties connecting their systems and using the shared record across relevant workflows.

Why Goldman Sachs’ Participation Matters

Goldman Sachs joins BNY and National Bank of Canada, which began transmitting live transactions onto the 1Source ledger in October 2025. Its participation adds a major securities borrower to a platform whose usefulness depends partly on how many counterparties use it. PR Newswire+1

That network effect is important in securities finance. A shared ledger can reduce discrepancies between connected parties, but it cannot eliminate reconciliation work across the broader market if counterparties continue to operate outside the platform. Wider adoption could therefore determine how much of the potential operational benefit firms realize.

EquiLend says additional counterparties are in the process of adopting 1Source, but the announcement does not specify how many transactions Goldman Sachs will process through the platform or which business units will use it.

The company also cites third-party estimates suggesting that industry-wide adoption could save hundreds of millions of dollars. Its product materials break down potential savings across reconciliation labor, duplicate infrastructure and losses associated with settlement failures and rate discrepancies. These figures are estimates of potential industry benefits, not disclosed savings already achieved by Goldman Sachs or the current participant group. Equilend+1

Post-Trade Modernization Beyond Blockchain

The announcement reflects a broader effort to modernize post-trade financial infrastructure as firms manage complex transaction lifecycles and tighter settlement timelines. In the United States, the move to a T+1 settlement cycle has increased the importance of accurate, timely transaction processing, leaving less time to resolve discrepancies after a trade.

Distributed ledger technology is one approach to that challenge, but its effectiveness depends on practical integration with firms’ existing books and records, operational controls and technology providers. EquiLend positions 1Source as an industry-wide utility that can work alongside existing systems rather than requiring institutions to replace their entire infrastructure. EquiLend+1

Goldman Sachs’ addition is a meaningful step in expanding the participant base, but it is not by itself proof of market-wide transformation. The next indicators to watch are additional live counterparties, transaction volumes, the range of lifecycle events recorded on the ledger and independently demonstrated reductions in reconciliation costs or settlement errors.

For securities finance, the core proposition is straightforward: if borrowers and lenders can consistently act on the same transaction record, they may spend less time resolving discrepancies and more time managing financing activity. Whether 1Source delivers that benefit at scale will depend on how broadly the market adopts it.

Market Landscape

Securities finance is an operationally complex part of capital markets, with lenders, borrowers, custodians and technology providers coordinating transaction details throughout the trade lifecycle. EquiLend’s expansion of 1Source reflects growing interest in using shared digital infrastructure to reduce duplicated records and post-trade processing friction.

• Distributed ledger technology: A shared record can help counterparties maintain consistent transaction information as rates, returns and recalls change.
• Post-trade automation: Reducing manual reconciliation may free operations teams from investigating discrepancies across separate systems.
• Settlement efficiency: Accurate, synchronized records can help reduce errors that contribute to settlement failures and incorrect accruals.
• Network adoption: The platform’s value depends on participation across counterparties, not simply the number of firms announced as users.
• Integration with existing systems: Institutions must connect the ledger to established books and records, controls and workflows to realize potential benefits.

The commercial test is whether additional firms use 1Source for meaningful volumes of live transactions and whether measurable operational improvements follow.
