Circle has publicly declined to unilaterally freeze stolen crypto assets, while Tether has demonstrated willingness to do so at law enforcement request. The divergence reflects fundamentally different issuer philosophies on censorship resistance versus compliance, and the question of which approach regulators will formally endorse remains open as Congress and the OCC continue stablecoin rulemaking.
For Armada's crypto-repo desk, this matters directly: USDC and USDT are candidate stablecoin collateral types, and issuer freeze authority is a material risk factor. A freeze on counterparty-held USDC could impair collateral access mid-trade, while USDT's freeze precedent introduces censorship risk. Legal counsel should assess how each scenario maps to margin call and liquidation procedures under Armada's MRA framework.
