Episode notes

- In Feb 2007 Sprenger helped launch a standardized subprime CDS index (ABX/HUBX) with major banks; senior tranches immediately traded far below par.
- That public pricing provided transparent evidence liquidity and marks were broken, validating the short thesis.

- Sprenger argues 2008 bailouts prevented necessary market correction and entrenched bigger future interventions.
