Circle has launched borrowing that lets institutions pledge Bitcoin and draw USDC without selling their coins, plugging one of the oldest treasury wishes in crypto into regulated custody.
The Digital Asset-Backed Borrowing service went live in Circle Mint on September 21 for eligible institutional clients, the company said in a statement. It arrives days after Arc, Circle's own Layer 1 blockchain, debuted on September 16, and extends the firm's push to wrap decentralised markets in institutional plumbing.

How It Works
The workflow runs in four steps inside one Circle Mint flow:
- Deposit BTC with Circle's regulated custody
- Mint cirBTC, Circle's wrapped Bitcoin backed 1:1 by native BTC
- Post cirBTC as collateral in a supported third-party lending market, starting with Morpho on Arc and Ethereum
- Borrow USDC straight into the Circle Mint balance
Rates and liquidations follow the rules of whichever market the client picks. Circle said it does not originate, underwrite or fund the loans, since all lending comes from independent third parties.
Why Treasuries Want It
Bitcoin-heavy balance sheets constantly face the same choice: sell coins to raise dollars or sit on idle collateral. Borrowing against BTC solves both, giving treasury teams dollar liquidity while keeping exposure to any further upside.
With Bitcoin holding near $86,000 at eight-month highs and ETF inflows running for four straight days, demand for ways to put idle coins to work without triggering a sale is rising across trading firms and corporate treasuries.
Why This Matters for Stablecoin Plumbing
The launch shows where stablecoin competition is heading: away from simple issuance and toward the credit layer. Whoever controls collateral, custody and settlement in one workflow owns the most profitable stretch of institutional crypto finance.
For USDC, each borrowed dollar also deepens circulation backed by real collateral demand rather than trading speculation, a quality regulators and risk officers both prefer.
What to Watch Next
- More lending venues beyond Morpho, and how fast volumes build on Arc
- Collateral behaviour in the next selloff, the first stress test for cirBTC liquidations at scale
- The GENIUS Act rollout in the US, which sets the federal frame stablecoin credit will operate inside
