Basis Trade Hedge Fund Repo Haircut Stress Modeling

The Mechanics of Treasury Cash-Futures Basis Trade Arbitrage

The Treasury cash-futures basis trade exploits tiny pricing discrepancies between cash Treasury notes and corresponding futures contracts. Utilizing the analytical engine of the treasury yield shock simulator reveals the extreme systemic vulnerabilities that emerge when massive fund leverage interacts with repo haircut adjustments.
