The Unit Economics of Deal Origination: How Spread Compression Is Reshaping Middle Market Lending Platforms

The structural transformation of middle market direct lending over the past three years has been defined by a single, unrelenting trend: spread compression. According to McKinsey’s Global Private Markets Report 2026, drawing on Kroll StepStone Private Credit Benchmarks, global new-issue direct loan median spreads peaked at 716 basis points in March 2023, then fell to 666 basis points at year-end 2023, 596 basis points at year-end 2024, and 544 basis points at year-end 2025.¹ At the upper end of the market, where private lenders compete most directly with the broadly syndicated loan market, the pressure has been even more acute: participants at the Debtwire Private Credit Forum in New York reported in late June 2025 that best-in-class unitranche transactions were pricing around 475 basis points, while the premium that middle market borrowers had historically enjoyed — once a 200-basis-point advantage over upper middle market credits — had narrowed to roughly 100 basis points.²

The arithmetic of this compression is unforgiving. The same McKinsey analysis found that three-month SOFR averaged 4.35 percent in 2025, down from 5.27 percent in 2024, and that together with declining spread premiums, all-in new-issue yields fell to approximately 9.3 percent in 2025 from 10.5 percent in 2024.¹ The Cliffwater Direct Lending Index, which tracks approximately 21,000 directly originated U.S. middle market loan holdings across $549 billion in assets, recorded full-year 2025 interest income of 10.4 percent and a total return of 9.3 percent — still attractive on an absolute basis, but meaningfully below what was achievable only two years ago.³ For platforms that built their cost structures around a 700-basis-point spread world, the migration toward 500 basis points has exposed a painful internal question: how many basis points of that spread disappear into the cost of originating the deal in the first place?

That question now sits at the center of platform strategy. Whether a platform earns 544 basis points or 716 basis points on a $50 million transaction, the team required to source, structure, evaluate, and close that deal is largely the same. A 170-basis-point compression on a $50 million deal represents $850,000 in annual income that no longer exists. For a platform closing 10 to 15 transactions per year, that compression aggregates into a structural P&L problem unless origination efficiency improves commensurately. Understanding the unit economics of each origination channel has accordingly become a matter of platform survival rather than competitive optimization.

The Capital Base Driving the Squeeze

The proximate cause of spread compression is not difficult to identify. As McKinsey reports, closed-end direct lending dry powder stood at approximately $500 billion in the first half of 2025 — near all-time highs — and that figure understates the competitive pressure because it excludes capital raised through semiliquid, evergreen, and BDC vehicles, which must deploy continuously to generate yield.¹ The Alternative Credit Council and AIMA reported in December 2025 that the global private credit market had reached $3.5 trillion in assets under management, with capital deployment growing to $592.8 billion in 2024, a 78 percent increase over 2023 deployment volumes.⁴ A growing pool of capital competing for a finite — and, in 2025, modestly contracting — set of deals creates the conditions for exactly the pricing dynamic now evident in the market.

Direct lending volumes in the United States declined by approximately 10 percent in 2025, and deal count fell by approximately 16 percent, even as LBO deal size grew: average LBO deal size for direct lending rose 29 percent to approximately $380 million, compared with roughly $295 million in 2024 and $200 million in 2020.¹ Competition intensified not just among private lenders but between private credit and the broadly syndicated loan market, with refinancing flows between the two markets approaching near-parity in 2025. Documentation shifted in favor of borrowers as well; covenant-lite transactions rose to 21 percent of direct lending deals in 2025, up from 4 percent in 2023.¹ This is the environment within which origination teams are operating.

Mapping the Cost Structure of Origination Channels

Middle market lending platforms source deal flow through several primary channels, each with materially different cost structures. Direct sponsor coverage deploys dedicated professionals — typically at the managing director or senior credit officer level — against a defined set of private equity firms. These professionals generate deal flow through sustained relationship investment: in-person meetings, market intelligence sharing, and the credibility that comes from closed transactions. The fixed cost of this model is substantial. Senior origination professionals at established platforms command total compensation packages that are non-trivial relative to the spread income generated by a single middle market transaction, which means that deal velocity and win rates are critical efficiency variables. If a coverage professional covers a portfolio of sponsors generating a dozen deal leads per year and the platform wins three or four, the per-deal cost of coverage must be measured against three or four closings — not twelve opportunities.

Intermediated deal flow, sourced through placement agents, capital markets advisors, and investment bank syndication desks, operates under a different economic model. These intermediaries receive fees — typically expressed as a percentage of committed capital — only when a transaction closes, meaning there is no fixed cost to accessing this channel. The trade-off is competitive transparency: broadly marketed processes expose deal economics to multiple bidders simultaneously, compressing margins and lowering win rates relative to direct sponsor relationships where incumbent lenders benefit from relationship stickiness. For platforms that rely heavily on intermediated flow, the variable nature of the cost is appealing, but the economics of each closed deal are less favorable than deals sourced through proprietary channels.

Bank referral partnerships represent an increasingly important third channel. As regional and community banks have retrenched from middle market lending in response to capital requirements and balance sheet discipline, their relationship teams have sought structures that allow them to continue serving borrowers while placing the credit risk with non-bank lenders. These partnerships generate deal flow that often reaches private credit platforms before being broadly marketed, reducing competitive pressure and potentially improving deal terms. The cost structure is variable and typically more favorable than broad-market intermediary fees, making bank partnerships an attractive origination channel for platforms willing to invest in relationship development with commercial banking teams. The Preqin Private Debt 2025 outlook noted that banks are increasingly functioning as capital-referral utilities, channeling middle market risk toward asset managers — a trend Arrow Global CEO Zach Lewy described as one that “benefits us greatly, as capital for high-risk investments is increasingly channeled toward private credit and third-party asset management.”⁵

The Emerging Case for Content-Driven Origination

An origination channel that has received growing attention among platform operators is the use of thought leadership, research publication, and conference visibility to generate inbound deal flow. This model inverts the logic of traditional relationship-driven origination. Rather than deploying professionals to build relationships with potential referral sources, it invests in institutional visibility — market research, sector commentary, and a consistent presence at industry forums — to attract sponsors and borrowers who approach the platform based on demonstrated expertise.

The economic logic is compelling in a compressed-spread environment. A transaction sourced inbound from a borrower or sponsor who sought out the platform based on its market reputation carries origination costs that are structurally lower than either intermediated or direct-coverage flow. The upfront investment — research staff, conference participation, content development — is largely fixed and does not scale linearly with deal volume, unlike coverage professionals whose capacity constrains the number of relationships they can actively manage. Several platforms have made this investment deliberately. Northleaf Capital, for example, publishes quarterly private credit market updates drawing on Cliffwater benchmark data to provide institutional-quality market analysis, while citing the 9.5 percent gross new-issue yield environment evident through Q3-2025 as a data-anchored signal of ongoing return opportunity.⁵

The limitation of this channel is its long time horizon. Content and thought leadership do not generate immediate deal flow; they build the institutional brand that makes inbound inquiries possible over months and years. For early-stage or capital-constrained platforms, the lead time before returns are visible creates a genuine prioritization challenge. The resolution, adopted by a growing number of platforms, is to treat content investment as a complement to direct sponsor coverage rather than a replacement — a channel that generates incremental flow at low marginal cost, diversifying the origination mix without displacing the relationships that provide deal flow stability.

Technology Infrastructure as an Origination Lever

The unit economics of origination are also shaped by the infrastructure through which platforms track, manage, and attribute deal flow. Early-stage platforms often rely on informal relationship tracking — email threads, spreadsheets, individual memory. As AUM grows and deal flow increases, this approach becomes a source of value leakage: relationships that could be leveraged are not systematically tracked, deal sourcing attribution is unclear, and management cannot measure the profitability contribution of different origination channels with any precision.

Modern platforms invest in CRM systems and deal tracking databases that serve as institutional memory. These systems record all sponsor and intermediary relationships, track deal pipeline at each stage from initial conversation through closing, enable relationship managers to coordinate across teams, and — critically — provide attribution data on origination source and deal profitability by channel. In a market where spreads have compressed by more than 170 basis points over two years, the ability to know with precision that a given channel produces transactions at a lower cost per closed deal than another is not a luxury. It is a prerequisite for making rational capital allocation decisions about how to staff origination and where to invest relationship development resources.

Capstone Partners’ Q1 2026 leveraged finance analysis noted a growing concern among lenders that sourcing good deals has become structurally harder as deal volumes moderated — and that without a meaningful pickup in deal activity, many firms will fall short of deployment budgets.⁶ That concern is a direct reflection of origination infrastructure gaps: platforms without systematic sourcing visibility are the first to feel deal flow droughts, because they lack the relationship density and pipeline analytics to identify and pursue opportunities across multiple channels simultaneously.

The Diversified Portfolio Approach

The platforms best positioned for a sustained compressed-spread environment have deliberately diversified their origination mix rather than concentrating in a single channel. Direct sponsor coverage provides stability — incumbency advantages and long-term relationship equity — but carries high fixed costs and attrition risk when senior professionals depart with their networks. Intermediated deal flow provides breadth and deal access without fixed cost commitments, but at the expense of deal economics. Bank partnerships offer attractive cost structures and lower competitive exposure but require patient relationship investment. Content-driven inbound origination provides the lowest marginal cost per deal once the brand is established, but the payback period is long.

The unit economics argument for diversification is straightforward: a platform not over-indexed to any single channel reduces the sensitivity of its origination cost structure to disruptions. In a market where all-in yields have declined from 10.5 percent to 9.3 percent in a single year,¹ and where the Cliffwater Direct Lending Index’s 20-year average return of 9.5 percent is being tested by sustained compression,³ operational resilience in origination is as important as credit discipline in underwriting. McKinsey’s data makes the concentration risk concrete: the top 25 managers accounted for approximately 72 percent of total fundraising in 2025, and the seven largest platforms grew AUM at roughly 20 percent annually from 2022 to 2025 — scale advantages that amplify the origination infrastructure gap between large and mid-sized platforms.¹

Conclusion

The middle market direct lending landscape has entered a structurally different phase. Spreads that peaked at 716 basis points in March 2023 had compressed to 544 basis points at year-end 2025 on a global basis,¹ and the dynamics driving that compression — record dry powder, growing competition from the syndicated market, and the entry of retail-oriented capital facing ongoing deployment pressure — have not resolved. Within this environment, the origination cost structure of a lending platform has become a primary determinant of profitability rather than an operational footnote.

Platforms that built their economics around opportunistic deal flow and broad-based relationship networks face a genuine reckoning. The fixed costs of those models — coverage teams, relationship managers, deal sourcing infrastructure — were sustainable when spreads provided ample margin. With all-in yields at approximately 9.3 percent and declining,¹ and with interest income at the CDLI level running at 10.4 percent against a backdrop of increasing competitive pressure,³ the math demands precision. The platforms that have moved earliest to systematize origination, diversify their sourcing channels, develop bank partnerships, and invest in content-driven brand equity are accumulating structural advantages that will compound as competitive pressure persists. Understanding the per-deal cost of each origination channel is no longer an analytical exercise reserved for operational reviews. It is a strategic instrument — and platforms that have sharpened it will be better positioned to protect their economics as the market continues to evolve.
