Private credit grew by taking on riskier loans that banks shed after Dodd-Frank, making the core banking system safer. However, banks now provide wholesale leverage to these private credit funds with minimal due diligence, creating a new, less transparent concentration of risk.

Don't wait for public credit spreads to blow out as a warning sign. In a system where sovereign debt is the primary vulnerability and corporates are easily bailed out, credit spreads have become a coincident, not leading, indicator. The real leverage risk is hidden in private credit.

Unlike the concentrated banking risk of 2008, today's risk is more diffuse. The danger isn't a sudden collapse, but rather a slow degradation of returns as immense pools of private capital compete for a limited number of productive lending opportunities.

Despite headlines blaming private credit for failures like First Brands, the vast majority (over 95%) of the exposure lies with banks and in the liquid credit markets. This narrative overlooks the structural advantages and deeper diligence inherent in private deals.

The greatest systemic threat from the booming private credit market isn't excessive leverage but its heavy concentration in technology companies. A significant drop in tech enterprise value multiples could trigger a widespread event, as tech constitutes roughly half of private credit portfolios.

Problem loans from the 2021-22 era will take years to resolve due to private credit's tendency to "kick the can." This will lead to a prolonged period of underwhelming mid-single-digit returns, even in a strong economy, rather than a dramatic bust.

While the private credit sector faces stress, its potential to trigger a systemic banking crisis is low. Banks' aggregate loan exposure to these institutions is a small percentage of total assets, and they are not on the front line for losses, which are first absorbed by fund investors.

While most US economic cycles appear healthy, the opaque private credit market represents the most significant systemic risk. Recent signs of stress, such as fund redemption limits and high exposure to volatile sectors like software, are reminiscent of the "contained" problems that preceded the 2008 financial crisis.

The primary concern for private markets isn't an imminent wave of defaults. Instead, it's the potential for a liquidity mismatch where capital calls force institutional investors to sell their more liquid public assets, creating a negative feedback loop and weakness in public credit markets.
