Concentration Limits
Definition
Concentration limits are portfolio rules that cap exposure to a single obligor, borrower, merchant, asset type, industry, geography, seller, or risk characteristic. Amounts above the cap may be excluded from the borrowing base or trigger a covenant breach.
Why it matters
Diversification only protects investors if it is enforceable. Concentration limits reduce the chance that one customer, collateral type, or borrower relationship drives losses across the whole deal. In receivables, MCA, invoice finance, and asset-backed private credit, concentration limits are often as important as headline default rates.
Common misconceptions
- •A pool with many contracts can still be concentrated if one obligor or sector drives most cash flow.
- •Concentration limits do not eliminate risk; they limit how much of a specific risk can support borrowing.
- •Breaching a concentration limit may reduce availability even before any actual default occurs.
Technical details
Common limit types
Single-obligor caps limit exposure to one payer or customer. Industry caps limit correlated sector risk. Geographic caps limit local legal, economic, or disaster exposure. Seller caps limit dependency on one originator.
Credit pools may also cap delinquent assets, modified assets, low-grade assets, high-LTV loans, non-prime borrowers, or non-standard documentation.
Borrowing base effect
If an obligor cap is 15% and one obligor accounts for 22% of otherwise eligible receivables, the excess 7% may be ineligible. The borrower can still own the receivable, but it does not support debt capacity.
This makes concentration limits a live liquidity control, not just a reporting statistic.
Stress behavior
Concentrations become dangerous when the same factor affects many assets at once, such as one merchant processor, one sector, one state foreclosure regime, one hospital system, or one platform originator.
Investors should review concentration reporting alongside delinquency and recovery reporting because concentration losses can appear suddenly.
