Insurance Companies and the Growth of Corporate Loan Securitization

Collateralized loan obligation (CLO) issuances in the United States increased by a factor of thirteen between 2009 and 2019, with the volume of outstanding CLOs more than doubling to approach $647 billion by the end of that period. While researchers and policy makers have been investigating the impact of this growth on the cost and riskiness of corporate loans and the potential implications for financial stability, less attention has been paid to the drivers of this phenomenon. In this post, which is based on our recent paper, we shed light on the role that insurance companies have played in the growth of corporate loans’ securitization and identify the key factors behind that role.

Leverage Ratio Arbitrage All Over Again

Leverage limits as a form of capital regulation have a well-known, potential bug: If banks can’t lever returns as desired, they can boost returns on equity by shifting toward riskier, higher yielding assets. That reach for yield is the leverage rule “arbitrage.” But would banks do that? In a previous post, we discussed evidence from our working paper that banks did do just that in response to the new leverage rule that took effect in 2018. This post discusses new findings in our revised paper on when and how banks arbitraged.

Leverage Rule Arbitrage

Classic arbitrage involves the same asset selling at different prices; the leverage rule arbitrage we study here involves assets of different risk levels requiring the same amount of capital. The supplementary leverage ratio (SLR) rule, finalized by U.S. regulators in September 2014, requires a minimum ratio of capital to assets at the largest U.S. banks. The floor is higher for more systemically important banks, but not for banks with riskier assets. That non-risk-based aspect of SLR was intentional, since the leverage limit was meant to backstop (“supplement”) risk-based capital rules in case banks underestimate their asset risk and overstate their capital strength. As policymakers have noted and bankers have warned, if the leverage rule is the binding capital requirement, banks can “arbitrage” the rule by selling safer assets and replacing them with riskier, higher-yielding ones. The findings of our recent staff report are consistent with those concerns.
