Portfolio concentration risk is the central governance question for MCA funders: how to deploy capital across many merchants without creating outsized exposure to any single risk factor. Updated 2026-06-28.
Why concentration matters.
MCA portfolios are inherently lumpy. A funder with $200M outstanding might have:
- 4,000 merchants averaging $50K balance.
- 8 industries concentrated by historical preference.
- 3–5 states accounting for 60% of volume.
- 20 brokers delivering 70% of submissions.
Any concentrated dimension can suddenly become a tail risk: industry recession, state regulatory action, broker fraud, key merchant default.
Four primary concentration dimensions.
1. Industry concentration.
- Typical funder limit: 20–25% per industry.
- Strict funders: 15% per industry.
- Specialist funders: 40–60% concentrated by design (trucking-focused, restaurant-focused).
- Warehouse covenant: most facilities cap industry at 25%.
Concentration tail-risk examples:
- Trucking concentration 2023–2026: funders heavy on trucking saw 8–15% portfolio losses during freight recession.
- Restaurant concentration 2020–2021: restaurant-heavy funders saw 15–25% portfolio losses during COVID closures.
- Cannabis concentration ongoing: federal enforcement risk creates binary outcome scenarios.
2. Geographic concentration.
- Typical funder limit: 15–20% per state.
- Some funders cap MSA (metropolitan statistical area) at 5–8%.
- Top-3 state concentration often limited to 40–50%.
Geographic tail-risk examples:
- Florida hurricane exposure: funders with FL concentration face seasonal portfolio stress.
- California regulatory exposure: disclosure law changes can trigger portfolio restructuring.
- Energy state exposure (TX, OK, ND): oil price volatility affects deposit patterns.
3. Broker concentration.
- Typical funder limit: 5–10% per broker.
- Some funders cap top-5 brokers at 25% combined.
- Custom-program brokers may exceed standard limits with compensating controls.
Broker tail-risk examples:
- Broker fraud: isolated cases of broker-orchestrated fraud have caused funders to write off 8–15% of portfolio.
- Broker defection: loss of top broker can affect 5–15% of origination volume.
- Broker performance degradation: broker portfolio quality decline can drive defaults concentrated in single source.
4. Merchant size concentration.
- Typical funder limit: 1–2% per merchant (single merchant cannot exceed 1–2% of total portfolio).
- Some funders cap absolute dollar exposure ($500K–$1M maximum per merchant).
- Repeat customer accumulation requires careful aggregation.
Size tail-risk examples:
- Large single merchant default can erase 2–5% of portfolio in one event.
- Funders that grow merchants over multiple renewals risk creating outsized positions.
Secondary concentration dimensions.
Channel concentration.
- Direct vs. broker-originated mix typically 30/70 or 20/80.
- Heavy direct concentration creates customer acquisition cost risk.
- Heavy broker concentration creates broker dependency risk.
Vintage concentration.
- Quarterly origination clusters reveal economic environment exposure.
- A funder with 40% of book originated in Q4 2023 faces concentrated exposure to that vintage's performance.
Capital source concentration.
- Reliance on single warehouse line creates funding risk if bank pulls.
- Most funders diversify across 2–4 warehouse providers + syndication base.
FICO concentration.
- Sub-580 FICO concentration above 30% creates pricing power risk.
- Above-680 FICO concentration above 50% creates margin compression risk (compete with cheaper bank loans).
Concentration measurement methods.
HHI (Herfindahl-Hirschman Index).
Sum of squared market shares; standard concentration metric.
- HHI under 1,500: well-diversified.
- HHI 1,500–2,500: moderately concentrated.
- HHI over 2,500: highly concentrated.
Top-N share.
Percentage of portfolio in top N entities (industries, brokers, merchants):
- Top-3 industry share over 60% = concentrated.
- Top-5 broker share over 50% = concentrated.
- Top-10 merchant share over 15% = concentrated.
Gini coefficient.
Inequality measure adapted to portfolio distribution.
Warehouse covenant compliance.
Most warehouse facilities impose concentration covenants:
- Industry concentration cap.
- State concentration cap.
- Broker concentration cap.
- Single-merchant exposure cap.
- FICO mix requirement.
- Vintage mix requirement.
Covenant breach triggers:
- Mandatory portfolio rebalancing.
- Reduced advance rate on new originations.
- Required equity injection.
- Worst case: facility termination and book wind-down.
Concentration risk in 2026.
- Trucking-concentrated funders face elevated stress due to freight recession.
- Cannabis-concentrated funders face binary regulatory outcomes.
- New York-concentrated funders face disclosure law compliance costs.
- Broker-concentrated funders face renegotiation pressure as PE acquires brokers.
Concentration management strategies.
- Industry diversification. Target maximum 18–22% per industry.
- Geographic expansion. Active state-by-state diversification programs.
- Broker recruitment. Continuous addition of new brokers to dilute top-broker concentration.
- Merchant size discipline. Hard caps on single-merchant exposure.
- Renewal management. Re-tiering merchants who would exceed size limits.
Common mistakes.
- Implicit concentration through correlation. Restaurant + retail in tourist-heavy state correlate; "diversified" portfolio may concentrate on tourism risk.
- Hidden geographic concentration. Broker headquartered in one state may submit primarily that state's deals.
- Vintage clustering. Origination volume spikes create vintage concentration even when individual deals are diversified.
Funder transparency.
Most funders do NOT publicly disclose concentration metrics. PE-owned funders share with sponsors; bank warehouse partners receive monthly disclosure. Merchants and brokers typically cannot see funder concentration.
Signals of concentration risk.
- Industry-specific declines or rate increases.
- State-specific declines.
- Sudden broker tier changes affecting one segment.
- Capital allocation slowdowns in specific verticals.
Concentration limits in fund documents.
Syndication and securitization vehicles often impose stricter concentration limits than warehouse facilities. A funder operating through asset-backed securitization typically has 5–10% industry caps and 1% single-merchant caps.
Common confusions.
First, "diversification eliminates concentration risk." Wrong — correlated diversification still concentrates.
Second, "small funders are inherently concentrated." Partially true — capital base limits diversification.
Third, "concentration measured only by industry." False — multi-dimensional.
Fourth, "warehouse covenants are negotiable." Partially true — initial covenants set; modifications rare during facility life.
Fifth, "PE acquisition resolves concentration." Sometimes — PE often pushes for more aggressive diversification post-close.
