Private Credit's Quiet Takeover of Mid-Market Lending

The numbers from August 2025 confirmed what practitioners in the market have known for several years: private credit has become a structural feature of the global lending landscape, not a niche strategy. With assets under management exceeding $1.7 trillion globally, the private credit market has grown by roughly 60% in five years, absorbing lending mandates that regional and community banks have retreated from under the pressure of Basel III capital requirements, post-2008 regulatory tightening, and margin compression in traditional lending businesses.

The growth story is compelling. For institutional investors — pension funds, sovereign wealth funds, endowments — private credit has delivered attractive risk-adjusted returns at a time when public fixed income offered negative real yields. For corporate borrowers in the mid-market, private credit has been a reliable source of capital when traditional bank credit tightened. For the general partners running the funds, the fee economics are excellent. By most measures, the growth of private credit looks like a functional market filling an actual gap.

But markets are not just flows and returns. They are the environments in which businesses survive or fail, workers keep or lose their jobs, and communities either gain economic anchors or watch them disappear.

Regional Banks Left a Vacuum — and Communities Felt It

The retreat of regional banks from mid-market lending is not a mystery. Following the post-2008 regulatory environment, the capital requirements for holding leveraged loans on bank balance sheets increased materially. For smaller regional banks operating on thin margins, the risk-adjusted economics of mid-market corporate lending deteriorated relative to safer, lower-weight alternatives. Simultaneously, the larger money center banks moved up-market toward larger, rated corporate borrowers.

The mid-market borrower — companies with $10 million to $150 million in EBITDA — found themselves with fewer credible bank partners. Private credit funds stepped into that vacuum.

What tends to get lost in this analysis is that mid-market companies are often the economic anchors of smaller cities and towns. They are the manufacturers, distributors, and service providers that employ hundreds of people in communities that don't make the financial press. When their access to credit depends entirely on opaque private funds rather than local institutions with community ties, the relationship between capital and community changes in ways that are difficult to observe but easy to feel.

The Opacity Problem Nobody Wants to Discuss

The problem is what happens when the cycle turns, and nobody can see clearly into the engine room.

Private credit markets are, by definition, not publicly traded. There is no daily mark-to-market, no visible secondary market clearing price, and no regulatory requirement for the kind of disclosure that public debt markets demand. Portfolio companies are not required to report their financial performance publicly. The credit metrics that would allow outside observers to assess the health of a private credit portfolio are typically proprietary.

This opacity was an acceptable tradeoff when private credit was a small, sophisticated corner of the market. At $1.7 trillion AUM — and growing — it is no longer small. The concentrated exposure of certain institutional LPs to private credit strategies, combined with the illiquidity of underlying portfolios, creates a systemic risk that is difficult to quantify precisely because the data is not public.

Consider the historical parallel: before 2008, the complexity and opacity of structured credit products was consistently cited as a feature — sophisticated investors could identify value that unsophisticated markets would misprice. Until the moment it became the liability that made orderly deleveraging impossible. The opacity that attracted capital became the opacity that prevented price discovery.

Private credit is not structured credit. The comparison has limits. But the fundamental dynamic — a rapidly scaling asset class where the opacity that attracts capital also obscures risk accumulation — is not unique to CDOs. It is a feature of any market that grows faster than its disclosure and regulatory infrastructure.

When private credit portfolios come under stress, the consequences don't stay in the fund documents. Companies restructure, cut workforces, or close. The communities that depend on those employers absorb the shock — often with far less warning than a public market distress signal would have provided.

Market Notes Take

Private credit's growth is real, functional, and fills a genuine gap in the lending ecosystem. The LPs are not wrong to allocate there, and the borrowers are not wrong to use it. The market has worked as intended.

But the lack of transparency in private credit markets is a systemic risk that nobody in the industry wants to talk about seriously, because doing so would complicate the fundraising narrative. The opacity that made private credit attractive to yield-hungry LPs is the same opacity that will make orderly deleveraging difficult when the credit cycle turns.

And the credit cycle always turns. The question is whether the regulatory and disclosure infrastructure will have been built before it does, or whether we will be building it in the aftermath, as we have done every time before. The current trajectory suggests the latter. When it plays out, the portfolios will deleverage — and somewhere in that process, a company will restructure, a plant will close, and a community that relied on it will have to figure out what comes next. That is the part the fund documents never show.
