Why Lower and Core Middle Market Direct Lending Still Earnies Its Place in Portfolios

The crowding is real, but it is not evenly spread

The right place to be in direct lending is not where the crowd is. It is in the lower and core middle market, where borrowing needs are meaningful but the capital markets are still fragmented enough to resist lazy pricing. That is the why-now tension. The broader private credit complex has grown into a $1.5-2 trillion market and is forecast to reach $3 trillion by 2028. In the larger market, that scale is starting to show. Heavy inflows have brought intensified lender competition, while nearly 90% of newly issued institutional loans are now covenant-lite. In the largest segments, that supports the critique of a crowded yield chase.

The bull case and bear case diverge by segment

Bulls argue that direct lending still belongs in portfolios because new deal demand and a large refinancing wave should keep borrowing activity healthy, while constraints on regional bank lending continue to push companies toward private lenders. Bears counter that too much capital is chasing the same borrowers, with pressure to deploy at wider spreads and potentially overly optimistic valuations.

The cleaner response is to stay where inefficiency still helps protect discipline. In the lower middle market, limited inflows have helped preserve stronger covenants, more conservative leverage, and closer alignment between investors and business owners. That is the sweet spot now: enough demand for deals to exist, but not so much capital that investors are renting balance sheets instead of buying a defensive piece of the business.

Why the lower and core middle market still has better economics

The appeal here is not just ideological. It is economic.

Inefficiency can support underwriting discipline

Think of the larger leveraged loan market as the express lane: fast, crowded, and easier for large lenders to enter. The lower and core middle market is slower, messier, and harder for big machines to scale without doing the real work. At this size, direct lending is still a relationship business more than a trading business. Fewer capital providers, more labor intensity, and less standardization mean lenders can underwrite the borrower, not just the model, in a space that remains less trafficked, less efficient, and more labor intensive.

That changes the income profile in a practical way. In bigger segments, investors are increasingly being asked to accept higher leverage and looser legal protection for a bit more yield. With covenant-lite deals becoming common, structural protection can weaken just when trouble arrives. In the lower and core middle market, stronger covenants and more conservative leverage can improve early-warning signals and borrower discipline. The goal is not just to collect a coupon; it is to own a position that is structurally sturdier.

Growth can support debt service, not just the equity story

This is also where the asset class starts to look more than a defensive bond substitute. Empirical work on BDC lending shows that BDC capital acts as a substitute for traditional financing and is associated with employment growth and patenting activity. That does not guarantee growth in every deal, but it does suggest that the borrower base can still expand in ways that help service debt.

For family offices, endowments, and advisors, that is the practical split: core middle-market direct lending can serve two roles at once. It can provide a steady income layer with better structural protection, while also offering exposure to a part of the economy where growth is still possible rather than fully arbitraged away.

Why the next 12 to 24 months may favor selectivity over scale

Over the next year to two, the edge is more likely to come from deal and manager selection than from simply attaching your name to the biggest balance sheet. Direct lending is now a $1.5–$2 trillion market, while sponsors still have over $2 trillion in dry powder waiting to be deployed. When the easiest large deals remain crowded, larger lenders eventually have to reach farther. For smaller, more focused lenders, that spill-over can make the lower and core middle market a better opportunity set, not just a fallback bin.

The smaller end can still be selective in 2026

The near-term backdrop is improving, but it is not an unqualified all-clear. Policy and tariff uncertainty slowed middle-market activity earlier, followed by a resumption of U.S. deal flow after Labor Day. The setting is now described as ripe with attractive investment opportunities in 2026. That matters because better deal flow only helps if investors can be picky.

The segmentation is what matters here. The lower and core middle market can benefit from healthier activity without absorbing the same pricing pressure because that space remains less trafficked, less efficient, and more labor intensive. At the same time, direct lending still has support from a regulatory and tax regime that favors business expansion, along with constraints on regional bank lending that keep borrowing demand alive. That combination gives disciplined lenders room to choose deals rather than chase them.

The risk is that headlines get noisy before fundamentals do. Larger firms could face negative headlines related to performance deterioration, overly optimistic valuations, or greater use of PIK facilities. If that happens, capital may look for quieter places to park. In that scenario, the lower and core middle market is where that overflow demand is most likely to improve selectivity rather than worsen pricing.

What would weaken the case?

A good rule of thumb: if you are buying into a crowded bucket simply because yields look attractive, you are probably in the wrong part of the market. In lower and core middle-market direct lending, the right signal is not just more money chasing deals. It is better deals, better structures, and enough demand to keep income resilient.
