Private Credit, SRTs and the Banking System: Mind the Protection Gap

Author

  • Riccardo Russo

Abstract

Private credit funds have emerged as major players in corporate lending and protection sales to banks within the SRT market. This paper models a contagion loop between the banking system and private credit funds working through SRTs. The loop is activated by two elements whose interaction is scarcely formalised in the literature: the circular leverage embedded in SRT financing and the liquidity mismatch introduced by semiliquid private credit funds. Together, they can result in shrinking protection for banks, i.e. a protection gap. Implemented through a simulation, the model provides evidence on the impact of this mechanism on banks’ capital relief and lending capacity, and represents a useful risk-assessment tool to both private and public agents.
