Fund finance refers to the credit facilities and structured loans used by private markets funds — private equity, infrastructure, real estate and private credit — to manage liquidity, time capital deployment, and optimize returns across a fund's life. The global fund finance market is estimated at approximately US$1 trillion, with annual demand exceeding US$600 billion.
Answer
Fund finance is the category of credit products and structured loans used by private markets funds — private equity, infrastructure, real estate, and private credit — to manage liquidity, bridge investments, and optimize capital deployment across a fund's life. The global fund finance market is estimated at approximately US$1 trillion outstanding, with annual demand exceeding US$600 billion according to industry surveys.
From the LP perspective, fund finance is increasingly relevant because it affects how returns are reported, how leverage is structured, and what rights LPs need to protect themselves in their partnership agreements.
The Fund Finance Toolkit
Fund finance encompasses several distinct product types, each serving different purposes at different stages of a fund's life.
1. Subscription Credit Facilities (Capital Call Lines)
The most common and longest-established fund finance product. A subscription facility — also called a sub-line or capital call facility — is a revolving credit line to a private fund vehicle, secured by the fund's legal right to call capital from its limited partners. The fund draws on the line to make investments, pay expenses or bridge distributions, then repays by issuing a capital call to LPs.
How they work: The lender (typically a bank) takes a security interest in the GP's right to call LP commitments and in the bank accounts into which capital call proceeds are deposited. Credit is sized based on the quality and total committed capital of the LP base — larger sub-lines are available to funds with predominantly institutional LP bases of high-quality investors.
Why GPs use them: Sub-lines reduce the operational burden of capital calls (fewer, larger calls rather than many small ones), allow investments to be funded immediately rather than waiting for LP wires, and — critically — improve IRR by starting the investment return clock after the sub-line repayment rather than from the original commitment date.
The IRR controversy: Because IRR is sensitive to timing, using a 12-month sub-line before calling LP capital can add 2–4 percentage points of IRR on the same underlying investment performance. This makes benchmarking between funds that use sub-lines heavily and those that use them sparingly unreliable. ILPA (the Institutional Limited Partners Association) has called for standardized disclosure of sub-line usage and time-adjusted performance metrics.
Market size: Sub-lines account for the large majority of fund finance transaction volume — 94% of survey respondents in the 2026 Global Fund Finance Symposium said they closed subscription financings in 2025, and 82% said sub-lines represent over two-thirds of their fund finance activity by volume.
2. NAV Loans (Net Asset Value Financing)
A NAV loan is secured by the equity value of a fund's portfolio companies rather than LP commitments. It is typically used in mid-to-late fund life, when LP commitments are largely drawn and the portfolio has accumulated significant value.
Key uses: Returning liquidity to LPs without forced asset sales, funding follow-on investments within the existing portfolio, bridging a delayed exit, or — in stress — supporting a portfolio company that needs capital.
Market: Approximately US$100 billion outstanding globally in 2024, projected to reach US$350 billion by 2030. The fastest-growing segment of fund finance. (See also: NAV Lending in Private Equity, Explained.)
3. Hybrid Facilities
A hybrid facility combines elements of both a sub-line (secured by unfunded LP commitments) and a NAV loan (secured by portfolio equity). Useful for mid-life funds where both elements have meaningful value. Hybrids allow for higher total borrowing capacity than either pure structure at the relevant life stage.
2026 outlook: 94% of 2026 fund finance survey respondents expect hybrid facility use to increase. They are particularly common in infrastructure and real assets funds, where portfolios generate cash flows that support partial NAV-based borrowing while commitments are still partially uncalled.
4. GP-Level Financing
Financing provided to the general partner entity itself — not the fund vehicle — to fund:
- Carried interest monetization: GPs can borrow against vested but unrealized carried interest (the GP's share of profits), providing liquidity before exits are complete.
- Fund seeding and management company lending: Banks and private credit funds provide loans to management companies to cover operating expenses, fund launches or team-level liquidity needs.
- Co-investment funding: GPs often co-invest alongside their funds; GP financing can fund the GP's co-investment commitment.
5. Preferred Equity and Fund-Level Structured Solutions
In some transactions — particularly in secondary markets and continuation vehicle structures — sellers or buyers use preferred equity or structured credit at the fund level to facilitate transactions. These instruments sit between debt (senior NAV loans) and pure equity (LP interests) in the capital structure.
How the Market Operates
Lenders
The fund finance market is served by a tiered group of lenders:
Tier 1 banks: JPMorgan, Citigroup, Barclays, Deutsche Bank, HSBC and Goldman Sachs Lending provide subscription facilities and vanilla NAV loans. They focus on high-quality borrowers, benefit from strong LP bases, and operate at scale.
Specialty fund finance banks: Silicon Valley Bank (before its 2023 failure), Pacific Western, Investec, and MUFG built significant fund finance franchises. SVB's collapse in 2023 removed one of the market's most active participants and prompted some re-pricing of the asset class.
Private credit providers: Ares, 17Capital, Oaktree, Pemberton and others have built NAV lending and hybrid capabilities, often willing to do more complex or higher-leverage structures than banks.
Insurance companies: For long-duration term facilities — particularly in infrastructure and real estate — insurance companies have become significant providers, attracted by the match to their liability durations.
Documentation and Standards
Fund finance documents are governed primarily by English or New York law, with the Loan Market Association (LMA) in Europe and the LSTA in the US providing standard precedent documentation. The Institutional Limited Partners Association (ILPA) has published guidance on best practices for subscription line disclosure, including the recommendation that GPs report both traditional IRR and a "time-zero" IRR that adjusts for sub-line timing effects.
What Asset Owners Should Require
Institutional investors committing to private markets funds should address fund finance proactively in their due diligence and limited partner agreement negotiations:
LPA borrowing limits: Request explicit caps on total fund-level borrowing as a percentage of NAV or committed capital. Best practice is to cap subscription lines at a percentage of uncalled commitments (e.g., no more than 20% of total commitments) and NAV loans at a percentage of portfolio NAV (e.g., no more than 25–30%).
LPAC approval rights: For NAV borrowing above threshold levels or for borrowing that materially changes the fund's leverage profile, LPAC consent provides a check on GP discretion.
Performance reporting transparency: Require that performance reports disclose whether subscription lines have been used and provide time-adjusted return metrics (e.g., IRR calculated from the date of each capital call, not the investment date, to allow meaningful benchmarking).
Disclosure of outstanding fund finance: Quarterly reporting should disclose outstanding subscription line and NAV loan balances, covenant headroom, and repayment timeline — information that is material to understanding true fund leverage.
Fund finance has become standard infrastructure for private markets. Understanding its mechanics, its effects on reported returns, and the protections available in well-negotiated LPAs is now a basic competency for institutional allocators building and managing private markets programs.
