What Is Concentration Risk?
Concentration risk is the risk that arises from over-reliance on a single vendor, supplier, service provider, geographic region, or technology. When too much of a critical function depends on one party or one point, the failure or disruption of that party creates disproportionate impact on the organization.
Types of Concentration Risk
Concentration risk takes several forms: vendor concentration (too many services from one vendor), geographic concentration (too many vendors or operations in one region or country), technology concentration (over-reliance on one technology platform), service concentration (one vendor provides a critical single point of failure), and sector concentration (over-reliance on vendors in one industry). Each type requires different mitigation strategies.
Why Concentration Risk Matters
Concentration risk matters because it amplifies the impact of any single failure. If 80% of your infrastructure is on one cloud provider, an outage affects 80% of your operations. If all your critical vendors are in one country, a geopolitical event disrupts your entire supply chain. Concentration creates fragility — a single point of failure can cascade into a systemic crisis.
Identifying and Measuring Concentration
Concentration should be measured across multiple dimensions: spend concentration (what % of spend goes to top vendors), service concentration (how many critical services depend on one vendor), geographic concentration (what % of vendors/operations are in one region), and technology concentration (what % of infrastructure is on one platform). Thresholds should be set to flag when concentration exceeds acceptable levels.
How MPG Supports Concentration Risk Management
MPG's third-party vendor oversight module provides concentration analysis across vendor, service, geographic, and technology dimensions. Concentration thresholds trigger alerts when exceeded, and the module supports contingency planning and exit strategies for concentration points. Concentration risk is integrated into the enterprise risk register.
Key Takeaways
- Concentration risk arises from over-reliance on a single vendor, region, or technology
- Types include vendor, geographic, technology, service, and sector concentration
- Concentration amplifies the impact of any single failure — it creates fragility
- Concentration should be measured and monitored with defined thresholds
Frequently Asked Questions
How much concentration is too much?
There's no universal threshold, but common guidelines suggest no single vendor should handle more than 30-40% of critical services, and no single region should host more than 50-60% of critical operations. The right threshold depends on your risk appetite and the criticality of the service. MPG helps you set and monitor concentration thresholds.
How do we reduce concentration risk?
Strategies include: diversifying vendors (using multiple providers for critical services), geographic diversification (spreading operations across regions), exit planning (maintaining the ability to switch vendors), and contingency arrangements (backup vendors, in-house alternatives). The cost of diversification should be weighed against the risk of concentration.
