The SOFR discount

Journal of Financial Economics 2025 164, 103989 open access
The transition from London Interbank Offered Rate (LIBOR) to Secured Overnight Financing Rate (SOFR) affects the reference rate of floating-rate debt worth trillions of dollars. We provide the first evidence highlighting a benefit of the benchmark transition for debt markets. Focusing on the market for dollar-denominated floating rate notes (FRNs), we compare the yield spreads of FRNs linked to LIBOR and SOFR, issued by the same entity during the same month. After adjusting for the maturity-matched spreads from derivatives markets, we find significantly lower spreads for SOFR-linked FRNs. We link this SOFR discount to the enhanced price stability of SOFR-linked FRNs.

Safe Haven CDS Premiums

Review of Financial Studies 2018 31(5), 1856-1895 open access
Credit default swaps can be used to lower the capital requirements of dealer banks entering into uncollateralized derivatives positions with sovereigns. We show in a model that the regulatory incentive to obtain capital relief makes CDS contracts valuable to dealer banks and empirically that, consistent with the use of CDS for regulatory purposes, there is a disconnect between changes in bond yield spreads and in CDS premiums, especially for safe sovereigns. Additional empirical tests related to the volume of contracts outstanding, effects of regulatory proxies, and the corporate bond and CDS markets support that CDS contracts are used for capital relief.

An Explanation of Negative Swap Spreads: Demand for Duration from Underfunded Pension Plans

Journal of Finance 2019 74(2), 675-710 open access
The 30‐year U.S. swap spreads have been negative since September 2008. We offer a novel explanation for this persistent anomaly. Through an illustrative model, we show that underfunded pension plans optimally use swaps for duration hedging. Combined with dealer banks' balance sheet constraints, this demand can drive swap spreads to become negative. Empirically, we construct a measure of the aggregate funding status of defined benefit pension plans and show that this measure helps explain 30‐year swap spreads. We find a similar link between pension funds' underfunding and swap spreads for two other regions.

Active loan trading

Journal of Financial Intermediation 2021 46, 100868 open access
Using a novel dataset of leveraged loan trades executed by managers of collateralized loan obligations (CLOs), we document the importance of “active loan trades” – trades executed at a manager’s discretion. More active trading increases the returns to CLO equity investors, lowers collateral portfolio default rates, and increases the manager’s chances of closing a new deal. Examining the observed loan trades, we find that more active CLOs trade at better prices than less active CLOs, selling leveraged loans earlier and before they get downgraded. Our findings suggest that more active CLOs are better at anticipating deteriorations in loan credit quality.
