USDC is becoming a go-to collateral option for derivatives trading, with both crypto-native venues and traditional brokerages building around it. Coinbase International Exchange now settles perpetual futures in USDC, standardizing USD profit and loss without coin-margined products. Meanwhile, Marex, a multi-asset broker, is integrating digital assets and can translate stablecoin collateral into existing risk and legal workflows. The shift reflects growing institutional comfort with regulated stablecoins, though the trade-offs are real.
Coinbase's USDC-first design
Coinbase International Exchange made USDC the default for its international perpetual venue. That choice influences how conservative trading desks think about operational risk. By settling in USDC, the exchange avoids the complexity of coin-margined setups — where PnL fluctuates with the collateral asset's price. Instead, buying power is in USD terms and PnL is realized in USDC. It's a cleaner system, but it ties the venue's stability to USDC's peg.
Marex bridges traditional and crypto
Marex, a traditional broker, is building digital asset workflows that translate crypto plumbing into policies risk officers understand. That means onboarding procedures, collateral schedules, whitelisting, and tri-party custody. The firm can take USDC as margin and fold it into its existing risk framework. For institutions used to fiat and T-bills at FCMs — with bank hours and cutoffs — this is a step toward 24/7 mobility. But it also introduces new risks: depegs, blacklisting, chain or bridge exposure, and accounting treatment.
The risk trade-off
USDC offers operational speed and cleaner USD PnL compared to coin-margined setups, with more regulatory structure than many alternatives. But the trade-off versus fiat or T-bills is real. Fiat has no depeg risk and sits inside an established prudential regime. USDC moves 24/7, but that mobility comes with chain risk. Circle's Cross-Chain Transfer Protocol (CCTP) reduces bridge risk by enabling burn-and-mint of native USDC across supported networks — a key improvement. Still, the asset's freeze controls and monthly reserve attestations don't eliminate the possibility of a sudden depeg.
Regulatory clarity from MiCA
The EU's MiCA policy has been a tailwind for USDC. It's authorized as an Electronic Money Token under MiCA, giving institutions a clear regulatory box to check. That's a contrast with USDT, which is common on offshore venues but has an evolving regulatory posture under MiCA and relies on bridges or wrappers for cross-chain mobility. Deribit and several large offshore venues already allow USDC as collateral, often with portfolio margin. The question now is whether USDT can keep its dominant position as MiCA enforcement tightens.
For now, the market is watching how USDC's regulatory clarity and operational speed stack up against the risks. The next concrete test will come when a major depeg event hits — and whether the infrastructure built around USDC holds.
