Sky Advisor Proposes Halting New Core Vault Borrowing

The proposal is a risk-management signal more than a product change: freezing new minting while leaving repayment and collateral management open is the softer of the available brakes, suggesting BA Labs sees stress or concentration risk in the vault book rather than an immediate solvency problem. It lands hardest on existing borrowers who rely on Core Vaults for liquidity, since their positions become one-way — they can unwind but not scale. The open question is whether this is a precautionary pause tied to specific vault conditions or the first step toward a broader tightening of USDS credit.
