How is retail investor participation reshaping securities lending operations?
By Matt Barnett, Head of Operations
In April 2025, market volatility drove record-breaking volumes through U.S. market plumbing. The DTCC processed 545 million transactions in a single day—a 33% jump over the peak of the meme-stock frenzy. Just two days later, the NSCC cleared $5.55 trillion in trades.
That kind of volume isn’t just a statistic. It’s a stress test.
Because as retail trading scales, the systems behind it are under pressure like never before.
And it’s not just the volume. It’s the nature of it.
Retail doesn’t move like the institutional world. It’s millions of smaller trades, arriving at unpredictable times, in unpredictable sizes. It’s a tempo built for fragmentation, not aggregation.
And trading is only the beginning.
Retail investors are reshaping securities lending, too – bringing that same fragmented, high-velocity behavior with them.
Once a loan is made, it triggers a cascade of interdependent processes across systems. Every borrower request, recall, client sale, or corporate event initiates a chain of downstream actions. Partial recalls and returns require lender substitution and loan reallocation. That reallocation then drives the need for corresponding collateral adjustments, all of which must happen in near real-time.
Behind the scenes, each resulting position must be matched, allocated according to the chosen model (whether pro-rata, EFIFO, or another), and then confirmed.
Corporate actions—dividends, mergers, splits—can only be processed accurately if the underlying positions are properly reconciled.
At the same time, firms must meet strict regulatory reporting obligations. If any element is out of sync, reporting becomes inaccurate, and subsequent processes can fail.
One event is manageable. Millions, all moving at once, require orchestration.
The sheer force of retail investors is unrelenting. And when systems weren’t designed for this scale or speed, small cracks quickly become compounding risks.
Why scale needs a conductor
Institutional lending operated in a world of fewer clients, bigger trades, and predictable flows. That model breaks under the strain of retail.
Add velocity, volume, and variability—and suddenly, you’re not just managing loans, you’re conducting them. Keeping millions of moving parts in sync. Adapting in real time. Holding tempo even as pressure mounts.
Built for complexity in motion
Solving for scale meant going back to first principles, and redesigning post-trade from the ground up. Not with more people. Not with patches. But with infrastructure purpose-built for the complexity of modern securities lending.
So we built a post-trade brain: a smart coordination layer that connects every step of the lending lifecycle. It aligns systems, anticipates friction, and directs exceptions in near real-time.
It doesn’t just react faster, it prevents issues before they arise. By embedding intelligence into the process, it flags risks early, routes them automatically, and gives ops teams the visibility to stay ahead of the flow.
That’s how you manage millions of trades in motion. Efficiently, accurately, and without missing a beat.
Because resilience isn’t reactive. It’s built in from the start.
With securities lending, as with other investment activities, your capital may be at risk.
