Securities lending rarely makes headlines. It usually surfaces only when something in the back office breaks. Kris Gower, an executive at Circle, is trying to change that, arguing that the company's Arc blockchain and its USDC stablecoin could reduce settlement failures and costs in a corner of finance that still runs on legacy rails and banking-hour cutoffs.

Gower laid out the argument on the BitGo podcast, which aired around November 4-5, 2026. His pitch was straightforward: if trades settle in under a second and around the clock, fewer of them will fail.

How Arc and USDC Fit In

In securities lending, one institution lends stocks or bonds to another, with the borrower posting collateral—often cash or other securities—to cover the loan. The collateral and securities must change hands in a coordinated fashion. When one leg arrives late or not at all, the trade fails, and capital tends to sit idle while systems catch up.

Gower's conversation centered on how Arc and USDC target those frictions. Circle positions Arc as a venue where institutions can post tokenized collateral against USDC. According to Circle, settlement on Arc takes place in under a second, and the network runs 24/7. In practice, that means both legs of an exchange—tokenized collateral and USDC—can move on one network and one clock, rather than through separate systems with their own cutoffs. Circle's promotional materials frame this as removing the traditional settlement cutoffs that dictate when institutions can move money and collateral.

Circle's materials also pitch Arc and USDC for tokenized repurchase agreements, or repo, and for broader collateral mobility. Repo is a close cousin of securities lending: one party sells securities and agrees to buy them back later, functioning much like a short-term secured loan.

Circle says it is promoting instant repo settlement for a range of financial institutions, framing the approach as a way to rely less on conventional settlement systems such as Fedwire, the Federal Reserve's payment network.

A Short Track Record

Arc is a young network. Its public mainnet launched on September 16, 2026, with USDC integrated from the start. Circle says the chain had more than 100 institutional partners on day one, including a collaboration with the Depository Trust & Clearing Corporation (DTCC) aimed at advancing the tokenization of securities.

The network also has a native token, ARC, minted by Circle, with a total supply of 10 billion. Circle intends to use ARC for future proof-of-stake security and governance on the Arc network.

USDC, meanwhile, continues to grow. Circulation reached approximately $74 billion as of late October 2026, and on-chain activity has picked up on the newly launched Arc platform.

Why the Settlement Angle Matters

Securities lending and repo are where large institutions move collateral to fund positions and manage liquidity. Settlement failures carry real costs: they tie up capital, create operational headaches, and force firms to hold buffers against things going wrong.

Cutoffs are the other piece of the problem. Traditional systems close, and when they do, collateral that could be put to work sits still until the next window opens. A network that runs 24/7 lets institutions move collateral when they need it, not when the clock allows.

What It Means for Circle

For Circle, Arc marks a strategic step beyond issuing a stablecoin. The company is trying to own the rails as well as the asset that moves across them.

Arc launched only in September 2026, however, so its track record under stress is short. Institutional partnerships at launch are a promising signal, but live settlement volume is the real test.

The ARC token is another open question. With 10 billion tokens and a planned role in network security and governance, how Circle distributes and decentralizes that supply will shape how independent Arc actually becomes from its creator.

Three things are worth tracking: whether the DTCC collaboration produces live tokenized securities on Arc; whether repo and securities lending activity on the chain moves beyond pilots; and how USDC circulation develops from its roughly $74 billion level as Arc matures.
