- NDFI stands for Non-Depository Financial Institution. These are financial intermediaries that perform financial services (like credit intermediation, asset management, lending, etc.), but do not accept deposits from the public in the way that banks do.
- Examples of entities that can be NDFIs include:
- Mortgage lenders/intermediaries
- Insurance companies
- Investment funds (mutual funds, hedge funds, private funds)
- Private credit / direct lending funds
- Broker-dealers
- Securitization vehicles, special purpose vehicles, and other credit conduits
Because these institutions don’t rely on deposit funding, they often depend on capital markets and credit lines (including from banks) to finance their operations.
What the “NDFI Lending Market” Refers To
When people refer to the NDFI lending market, they usually mean the market in which banks extend credit (loans, lines, etc.) to NDFIs. In this arrangement:
- Banks provide liquidity (loans, revolving credit, subscription lines, capital call lines, warehouse facilities) to NDFIs.
- The NDFIs in turn may use that funding to fund their lending, invest in assets, or operate their business.
- Thus, banks act as a funding source for nonbank financial institutions rather than lending directly to end-borrowers (individuals or nonfinancial businesses).
So “NDFI lending” is part of what links the traditional banking sector with the nonbank (shadow banking) sector.
Why Banks Lend to NDFIs (Drivers & Incentives)
- Diversification & new lending avenues: As traditional lending sectors saturate or face regulatory pressure, banks may look to new opportunities, such as providing wholesale credit to financial firms.
- Intermediation margins: Banks can earn interest, fees, and spread on these deals.
- Capital constraints: In some cases, banks with tighter balance sheet constraints may use these as off-balance or more efficient ways to manage risk or return. There is academic and regulatory observation that banks increase lending to nonbanks especially when their own capital is constrained. FDIC
- Growing scale of nonbank finance: As nonbank financial activity expands (e.g. private credit, funds, securitization), demand for credit lines or liquidity from banks grows.
Risks & Challenges in the NDFI Lending Market
There are several risks and challenges inherent in this kind of lending:
| Risk / Challenge | Description |
|---|---|
| Credit / Underwriting risk | Because NDFIs often engage in more sophisticated or leveraged strategies, their exposures may be riskier or volatile. |
| Transparency / Information asymmetry | It may be harder for a bank to assess the health, risk, or strategy of an NDFI compared to a nonfinancial borrower. |
| Regulatory / supervisory risk | Because NDFIs are not regulated like banks, regulatory oversight is weaker, making systemic risks more opaque. |
| Contagion / interconnectedness risk | Problems at an NDFI can propagate to the funding banks, especially if many banks are exposed to the same NDFI or strategy. |
| Liquidity risk | If an NDFI faces withdrawal pressure or market stress, the lines provided by banks may be drawn heavily, creating liquidity stress for the bank. |
| Concentration risk | If a bank or banks concentrate exposures in certain NDFI types (e.g. private credit, mortgage conduits), a shock in that sub-sector can hit multiple lenders. |
Regulators have recently become more attentive to these risks and are demanding more granular disclosures from banks about their NDFI exposures. Haynes Boone+2FDIC+2
For example:
- The FDIC’s 2025 Risk Review highlights that lending to non-depository financial institutions and private credit is a key credit risk for banks. FDIC
- The FDIC and other regulators are requiring banks with over $10 billion in assets to break out their NDFI lending into subcategories (such as mortgage intermediaries, private equity funds, business credit intermediaries, consumer credit intermediaries, etc.) for greater transparency.

- Some proposals aim to expand the granularity of reporting in banks’ call reports regarding NDFI exposure. Cadwalader+2Haynes Boone+2
Recent Trends & Market Size
- The NDFI lending market has grown rapidly in recent years. FDIC+3St. Louis Fed+3FDIC+3
- The annualized growth rate of bank loans to NDFIs has averaged ~ 26% per year since 2012. St. Louis Fed
- As of early 2025, bank lending to NDFIs is one of the fastest-growing segments of bank balance sheet expansion. St. Louis Fed+2FDIC+2
- Big banks dominate the space: As of Q4 2024, the “Big Four” US banks (JPMorgan, Bank of America, Wells Fargo, Citibank) together held ~47.8% of NDFI exposure. S&P Global
- The composition of NDFI exposures is relatively diversified: as of March 2025, U.S. bank loans to NDFIs by type were roughly:
- Mortgage intermediaries: ~23%
- Private credit / lending intermediaries: ~23%
- Business credit intermediaries: ~21%
- Consumer credit intermediaries: ~9%
- “Other” NDFIs (insurers, broker-dealers, pension funds, etc.): ~24% St. Louis Fed
So, a substantial portion of a bank’s “non-traditional lending growth” is going through NDFIs.
Why It Matters / Implications
- Systemic risk: The increasing interconnection between banks and NDFIs raises the possibility that stress in nonbank sectors could transmit to the banking system.
- Opacity: Because many NDFIs are less regulated, their risks may be harder to observe or monitor by public markets and regulators.
- Regulatory focus: The fact that regulators are pushing for more transparency shows that they see this channel as a potential vulnerability.
- Risk / reward balance: While it offers growth opportunities for banks, it demands more sophisticated risk management and due diligence.
