      "content": "- Flows in and out of the Treasury General Account triggered by the debt ceiling mechanism can:\n  - Create large swings in the repo spread.\n  - Distort the supply of repo funding for the Treasury market.\n- Applying the paper’s estimates to the expected debt ceiling lift-off in summer 2025 implies that:\n  - The repo spread could fluctuate by 20-30 basis points around the lift-off date.\n- A higher level of aggregate bank reserves and overnight reverse repo balance at the Fed can dampen the impact on funding spreads appreciably."
