Summary

Jonathan Lewinsohn provides a deep dive into the dynamics of credit investing, highlighting the role of industry microcycles and macroeconomic awareness in navigating the credit markets.

What Happened

Jonathan Lewinsohn of Diameter Capital Partners discusses the firm's approach to managing $25 billion across various credit strategies, focusing on the evolution of direct lending and CLOs. He explains how Diameter has successfully completed over 70 direct lending deals without defaults in nearly three years, despite the market's shifting perception of these assets from overhyped to underrated. Lewinsohn emphasizes the importance of understanding industry microcycles, particularly in sectors like telecom, housing, and healthcare, where technological changes and policy volatility create investment opportunities.

AI is identified as a 'super duper microcycle' with potential disruptions for software companies in direct lending portfolios. While AI presents significant opportunities, particularly in financing power and data centers, Diameter is cautious about long-term residual risks in chip finance. Lewinsohn also discusses the U.S. housing market, currently stagnant due to rising interest rates, but sees a potential rebound as a 'coiled spring,' especially in the renovation segment.

The episode sheds light on the competitive environment among creditors, noting increased willingness to use contractual loopholes and the rise of cooperative agreements to provide capital solutions. Lewinsohn shares insights on the insurance-driven investment grade market, where Diameter offers structured products to insurers seeking slightly higher yields than traditional investment grade assets. He warns of potential systemic risks in the asset-backed finance market, drawing parallels to the financial crisis.

Lewinsohn underscores the necessity of integrating macroeconomic assumptions into credit investment decisions, citing the resilience of the U.S. economy due to historically underlevered consumers and corporations. He highlights changes in consumer behavior, such as reduced demand for packaging, despite strong GDP in personal consumption. With Diameter's focus on relevancy rather than size, the firm caps fund sizes to maintain effective investment strategies.

Diameter's emphasis on staying technologically advanced is noted, with video being mandatory during Zoom meetings to enhance communication. The firm's strategic investments in tools like Ridgeline and Ascension Data reflect this commitment. Lewinsohn concludes with a reflection on the evolving norms and laws in the credit market, emphasizing the importance of not being a 'tourist' in any investment space.
