Risk Retention and Skin-in-the-Game Rules

Before the 2008 crisis, an originate-to-distribute model let banks make loans, package them into securitizations, and sell the resulting bonds to investors, collecting fees at each step with little at stake if the underlying loans later defaulted. Because the originator bore none of the downside, lending standards weakened — a bank profited the same whether the loans performed or not. Risk retention rules, introduced in the Dodd-Frank Act, require sponsors of most securitizations to retain at least 5% of the credit risk of the deal, typically by holding a vertical slice across all tranches or a first-loss horizontal slice at the bottom of the capital structure.

The idea is straightforward incentive alignment: if the sponsor loses money when the underlying loans perform badly, it has a direct reason to underwrite carefully rather than simply maximizing volume. The rule allows some exemptions — for instance, pools of loans meeting strict "qualified" underwriting standards can be exempt from retention — which shifts some of the practical debate toward how tightly those exemptions are defined.

A sponsor retaining a 5% vertical slice of a $500 million securitization keeps $25 million of exposure across every tranche, so if the underlying loans underperform, the sponsor absorbs losses right alongside outside investors rather than walking away unscathed.
