The Unseen Currents: Navigating Credit Microcycles in an Era of Technological Upheaval

This conversation with Jonathan Lewinsohn of Diameter Capital Partners reveals a critical, often overlooked, truth in credit investing: the most potent opportunities and risks lie not in broad economic cycles, but in the granular, industry-specific "microcycles" driven by rapid technological shifts and policy volatility. Lewinsohn argues that the conventional wisdom of focusing on macro trends or simply seeking "good businesses" is insufficient. Instead, investors must meticulously map the interplay between industry debt levels and disruptive change, understanding that immediate discomfort or complexity often precedes significant, durable advantage. This analysis is essential for sophisticated credit investors, portfolio managers, and allocators seeking to identify undervalued opportunities and avoid hidden pitfalls in today's rapidly evolving market, offering a distinct edge to those who can navigate these intricate dynamics.

The Hidden Costs of Technological Disruption: Beyond the "Non-Cyclical" Myth

The prevailing narrative in credit markets often categorizes industries as "cyclical" or "non-cyclical," with the latter, like software, being considered safe havens. Lewinsohn dismantles this comforting illusion, demonstrating how technological transformation can create "microcycles" that devastate even seemingly stable sectors. He points to the paradox of cybersecurity software, once a bastion against economic downturns, now facing disruption not from a recession, but from native cloud competitors offering AI-driven solutions. This isn't just about innovation; it's about how deeply entrenched debt within an industry amplifies the impact of technological change.

"What happened is native cloud companies came in. They offered a solution, said, don't unplug your existing, plug us in on a new pipe, see if we work, and then unplug. We have now a decline in some of the legacy software providers."

This highlights a key consequence: the assumption of stability in "non-cyclical" sectors can lead to mispricing of risk. Companies that relied on their mission-critical status and existing debt structures are now vulnerable to new entrants that can integrate with existing systems rather than forcing a disruptive replacement. The implication is that "non-cyclical" is a temporary state, constantly under threat from technological evolution, especially when combined with significant debt loads. This forces a re-evaluation of what constitutes a truly resilient business, moving beyond industry labels to a deeper analysis of competitive dynamics and technological integration.

The "Muffin Top" Problem: When Structured Products Create Unwanted Leftovers

The explosive growth of private credit and insurance-driven investment grade (IG)-like solutions presents a compelling opportunity for yield enhancement. Insurers, managing long-duration liabilities, seek higher returns than traditional IG offers. This has fueled demand for structured products, often creating senior, "muffin top" tranches that appeal to insurers. However, Lewinsohn's analogy of the Seinfeld episode "Top of the Muffin to You" brilliantly illustrates the inherent risk: what happens to the "stumps"--the residual, often illiquid, and harder-to-value parts of these structures?

"The one thing we're seeing is we really love the IG market. We love creating these assets for insurers, investing in them when they make sense for our funds. But some insurance solutions involve creating a muffin top and a stump. Because if you create a muffin top, you are creating structural seniority that makes for less risk, makes a lot of sense in the insurer's balance sheet, makes a lot of sense. What do you do with the stump?"

This points to a significant downstream consequence: the potential for these "stump" assets to accumulate in less transparent parts of the market, such as special situations or interval funds. While the senior tranches might appear safe, the residual risk, often unamortized and with uncertain future value, could pose a hidden threat. The conventional approach of chasing yield in structured products can lead to overlooking the problematic leftovers, creating a concentration of risk that may not be fully understood or priced by investors seeking only the "top of the muffin." This demands a rigorous underwriting process that scrutinizes the entire capital structure, not just the most appealing senior pieces.

The Unseen Advantage of "Making Sausage": Embracing the Messy Process

In an era where information is abundant but often superficial, Lewinsohn champions a deep, hands-on approach to macro analysis and investment decision-making. He eschews outsourcing macro views and instead emphasizes "making the sausage"--personally engaging with data, building models, and developing independent theories. This commitment to process, even when it's tedious and doesn't always yield immediate insights, creates a durable competitive advantage.

"Scott and I really believe in making the sausage. Scott does an enormous number of our trades. I do our macro. When CPI comes out, when the jobs report comes out, I go into it. I have my own models. I create my own charts. And most of the charts I create don't show me something."

The consequence of this approach is not just better analysis, but a more resilient understanding of the economy and markets. By personally wrestling with the data, Diameter Capital Partners can identify subtle shifts and avoid the pitfalls of relying on consensus views or incomplete information. This "discomfort now" of deep analytical work creates a "lasting advantage" because few competitors are willing to undertake such rigorous, time-consuming processes. It highlights that true insight often emerges not from finding immediate answers, but from the persistent, detailed work of understanding the underlying mechanisms.

Key Action Items:

• Embrace Microcycle Analysis: Actively identify industries with high debt levels facing technological disruption or policy volatility. Prioritize understanding the interplay between these forces over broad macro trends. (Immediate Action)
• Scrutinize "Non-Cyclical" Claims: Question the inherent stability of sectors like software. Analyze how new technologies and business models could disrupt established players, especially those with significant debt. (Immediate Action)
• Map the "Stump" Risk: When evaluating structured credit products or insurance solutions, meticulously analyze the residual or "stump" tranches. Understand where these assets are ultimately held and how their risks are managed. (Immediate Action)
• Develop Internal Macro Frameworks: Avoid relying solely on external economic forecasts. Dedicate resources to building and maintaining internal macro models and analytical frameworks to inform investment decisions. (Ongoing Investment)
• Prioritize Process Over Polish: Value the deep, often unglamorous, work of "making the sausage"--personally engaging with data, building models, and debating insights. This effort builds a unique informational advantage. (Ongoing Investment)
• Seek Durable Business Models: When underwriting credit, focus on businesses with a demonstrable ability to earn high returns on capital, even through economic downturns or technological shifts, rather than solely on industry labels or management teams. (Immediate Action)
• Foster Transparency and Flat Hierarchies: Cultivate an organizational culture that minimizes office politics and maximizes transparency to enable focused investment decision-making. (Ongoing Investment)
