Capital Source
Last updated October 1, 2026
A capital source is the money behind a loan: the fund, investor, lender or grant that supplied the dollars. Nonprofit loan funds and many Community Development Financial Institutions (CDFIs) instead build a "capital stack" from several outside sources, each with its own terms.
Common sources for a mission lender include:
- CDFI Fund awards. Grants, loans or equity from the US Treasury program under an assistance agreement with performance goals and reports.
- Bank capital. Loans, deposits, grants and equity equivalent investments (EQ2s). An EQ2 is a long-term, fully subordinated loan with a rolling term, so it acts like equity to a CDFI's senior lenders. US banks can get credit under the Community Reinvestment Act (CRA) for these investments.
- Foundation money. Grants and program-related investments (PRIs), made mainly to advance a charitable purpose rather than to earn income.
- Government programs. Money that seeds a revolving loan fund, where repayments are lent again under the program's rules.
Some money is restricted. A grant might only fund loans in one region. Under nonprofit accounting rules, those dollars sit in net assets with donor restrictions until the lender meets the restriction.
Worked example. A loan fund makes a $100,000 loan, paid 70% from a bank loan and 30% from a grant restricted to rural borrowers. The loan carries both tags: $70,000 and $30,000. When the borrower repays $10,000 of principal, $7,000 goes back to the bank pool and $3,000 to the restricted pool.
Why it matters for lenders
Each source wants to know how its money was used. Bank lenders often set loan covenants, such as a minimum net asset ratio or a ceiling on delinquency. Foundations may require a yearly accounting of how funds were spent, and a federal award may require loan-level data on every deal.
If a loan is not tied to its source, the lender cannot prove a restriction was met or show how much of each pool is lent out. It may even report the same dollar to two funders.
How it works in practice
At a CDFI, the loan officer checks which sources fit a deal before approval. A rural loan may fit a rural relending program; a large one may exceed a microloan cap. At booking, the closer records each source and its share, and repayments split the same way from then on.
Finance reviews committed, drawn, repaid and available balances by source every month. Moving a loan to a different source after booking should require approval and leave a history, because it changes what was already sent in funder reporting. Tags kept in a separate finance workbook drift out of date, and every report becomes a rebuild.

Funder Reporting
Funder reporting is the set of reports a lender sends to the investors, banks, foundations and government programs that supply its lending capital. The reports show how the money was used, how the loans are performing, whether covenants are met and what impact was achieved. Each funder sets its own content, definitions and due dates.
CDFI Fund
The CDFI Fund is the office of the US Department of the Treasury that certifies Community Development Financial Institutions and runs federal programs that support them. It makes grants and other awards, allocates New Markets Tax Credits, guarantees bonds and collects the annual reports that certified CDFIs must file to keep their status.
Revolving Loan Fund (RLF)
A revolving loan fund (RLF) is a pool of lending capital that is lent out, repaid and then lent again to new borrowers. Repayments flow back into the fund instead of returning to the original funder. RLFs are often started with grants or loans from federal programs such as the EDA, SBA or USDA, or from states, cities and foundations.
Community Reinvestment Act (CRA)
The Community Reinvestment Act (CRA) is a 1977 US law that encourages insured banks to meet the credit needs of their whole communities, including low- and moderate-income neighborhoods. Regulators rate each bank's performance. Banks often earn CRA consideration by lending to, investing in or partnering with CDFIs.
Loan Covenant
A promise in a loan agreement that the borrower will do, or not do, certain things while the loan is open. Covenants include sending financial statements, keeping insurance, staying above a minimum debt service coverage ratio and not taking on more debt without approval. Breaking a covenant can be an event of default, even if every payment is on time.
