Securitization Without Risk Transfer

Working Paper: CEPR ID: DP8769

Authors: Viral V. Acharya; Philipp Schnabl; Gustavo Suarez

Abstract: We analyze asset-backed commercial paper conduits, which experienced a shadow-banking "run" and played a central role in the early phase of the financial crisis of 2007-09. We document that commercial banks set up conduits to securitize assets worth $1.3 trillion while insuring the newly securitized assets using explicit guarantees. We show that regulatory arbitrage was the main motive behind setting up conduits: the guarantees were structured so as to reduce regulatory capital requirements, more so by banks with less capital, and while still providing recourse to bank balance sheets for outside investors. Consistent with such recourse, we find that conduits provided little risk transfer during the "run": losses from conduits remained with banks rather than outside investors and banks with more exposure to conduits had lower stock returns.
