A BDC that lends at a given yield and borrows at a lower one earns the spread on borrowed money as well as on its own. That is the case for leverage, and it is a real one.
The case against is that the assets being levered are loans, and loans have asymmetric outcomes. A performing loan returns principal and interest — that is the ceiling. A defaulted loan can lose a substantial portion of principal. Applying leverage to an asset whose upside is capped and whose downside is not amplifies the wrong side more than the right one.
Congress addressed this by capping BDC borrowing in statute. That cap, and how close a BDC sits to it, is one of the more consequential things an investor can examine.
The asset coverage requirement
BDCs are subject to an asset coverage requirement under the Investment Company Act. Broadly, it measures total assets less liabilities other than borrowings, relative to the borrowings — how much asset value stands behind each dollar of debt.
The applicable ratio was changed by legislation, effectively permitting greater leverage than had previously been allowed, subject to approval requirements and disclosure. Because the requirement has moved and the approval mechanics are specific, the current figure should be read from the statute rather than assumed from any secondary source, including this one.
What matters conceptually is that BDC leverage is bounded by statute in a way that private fund leverage is not. A private credit partnership’s leverage is limited only by its documents and its lenders. That statutory bound is one of the genuine protections the BDC wrapper provides. See BDC vs. private credit.
What happens at the boundary
A BDC that falls below its required coverage faces consequences that compound unpleasantly.
It generally cannot incur additional debt. This removes flexibility precisely when flexibility is most valuable.
Distributions are restricted. This is the serious one. BDCs elect regulated investment company treatment, which requires distributing substantially all taxable income. A coverage breach that restricts distributions puts the BDC between a statutory constraint and a tax requirement — a position with no comfortable resolution.
Asset sales may be forced. Restoring coverage means either raising equity, which is difficult when the share price is depressed, or reducing debt, which means selling assets. Selling private loans into a weak market realises poor prices, which reduces NAV further, which worsens coverage. This is the mechanism by which a manageable credit problem becomes a spiral.
The important observation is that coverage is a ratio, and it deteriorates from either direction: borrowing more, or asset values falling. A BDC that never adds a dollar of debt can breach its coverage requirement purely through portfolio marks declining. Leverage taken on in good conditions is measured against values that may not persist.
Why the arithmetic matters
Consider what a decline in portfolio value does to equity in a levered vehicle.
Assets are financed partly by borrowing and partly by shareholder equity. A loss falls entirely on the equity until the equity is exhausted. The higher the leverage, the smaller the equity cushion relative to assets, and the larger the proportional hit to NAV from a given percentage decline in asset values.
This is elementary and it is worth stating explicitly, because BDC marketing tends to present leverage in terms of enhanced income rather than amplified loss. Both are consequences of the same arithmetic, and only one of them appears in the yield.
The point applies with particular force to credit because of the asymmetry mentioned above. Leverage on an equity portfolio amplifies a symmetric distribution. Leverage on a loan portfolio amplifies a distribution with limited upside and a long left tail.
What to examine
Current coverage relative to the requirement, and the cushion between them. A BDC operating close to its limit has little room for portfolio deterioration.
How much value decline the cushion absorbs. This is a straightforward calculation from the filings and is more informative than the ratio alone.
The maturity profile. Debt maturing soon must be refinanced, and refinancing terms depend on market conditions and on the BDC’s own condition at that moment. A concentrated maturity wall is a risk independent of the amount borrowed.
The covenants. Credit facilities carry their own tests, and these frequently bind before the statutory requirement does. A facility covenant breach can force repayment on the lender’s timetable rather than the BDC’s. The facility terms are disclosed and are often more restrictive than the statute.
Fixed versus floating borrowing costs, and how they match the asset side. A BDC with floating-rate assets and fixed-rate liabilities benefits from rising rates; the reverse configuration does not.
The interaction with non-accruals. Non-accrual loans stop producing income while the debt financing them still requires payment. Rising non-accruals in a levered vehicle compress net investment income faster than the headline non-accrual rate suggests.
Whether the incentive fee is calculated on levered returns. A manager earning incentive fees on returns generated partly by leverage has an incentive to use it, and the alignment question is whether losses are equally reflected through a total-return lookback. See BDC distributions and return of capital.
The fair conclusion
Leverage is a normal and appropriate tool for a lending vehicle. Borrowing at one rate to lend at a higher one is what banks do, and BDCs doing it in a statutorily bounded way is not a defect in the structure.
What deserves attention is that the statutory limit is a ceiling, not a recommendation, and that a BDC operating near it has converted a moderate credit strategy into a leveraged one. Two BDCs holding similar loans at different leverage levels are offering meaningfully different risk profiles, and the difference will not be visible in the yield — which is precisely where an investor comparing them is most likely to look.

Frequently Asked Questions
How much leverage can a BDC use?
BDCs are subject to a statutory asset coverage requirement under the Investment Company Act that caps borrowing relative to assets. The applicable ratio was changed by legislation, effectively permitting greater leverage than was previously allowed, subject to board or shareholder approval and disclosure requirements. The current figure should be confirmed from the statute rather than assumed.
What is the asset coverage ratio?
A measure of total assets less liabilities other than borrowings, relative to the borrowings themselves. It expresses how much asset value stands behind each dollar of debt. A BDC falling below the required level faces restrictions, most significantly on paying distributions and incurring further debt.
What happens if a BDC breaches its asset coverage requirement?
It generally cannot incur additional debt and faces restrictions on distributions until coverage is restored. Because BDCs must distribute most taxable income to maintain their tax status, a coverage breach creates a difficult position, and it can force asset sales at unfavourable prices.
Why does leverage matter more in a BDC than in some other funds?
Because the underlying assets are loans with capped upside. A loan can return its principal and interest at best, but can lose substantially more than that in a default. Leverage applied to an asset with asymmetric downside amplifies losses more than it amplifies gains.
How should investors assess BDC leverage?
Look at where actual leverage sits relative to the statutory limit, how much cushion exists before a breach, the maturity profile and terms of the borrowings including any covenants, whether the debt is fixed or floating, and how the leverage interacts with non-accruals and portfolio marks.
