Monoline Policy
A standalone insurance policy that provides a single line of coverage, as opposed to a package policy bundling multiple lines.
What It Is
A Monoline Policy is a standalone insurance policy that provides a single line of coverage — for example, a standalone general liability policy, a standalone workers compensation policy, or a standalone commercial auto policy. Unlike a Commercial Package Policy (CPP) that bundles multiple coverage lines, a monoline policy covers only one type of risk.
Monoline policies are used when the insured needs only one line of coverage, when the specific coverage line requires a specialized carrier that does not offer package options, or when competitive market conditions favor separating lines across different carriers.
Common monoline placements include workers compensation, commercial auto (especially for trucking), professional liability, cyber liability, and excess/umbrella coverage.
Why It Matters for Brokers
Brokers must understand when monoline placements make sense versus when a packaged approach is superior. Splitting lines across multiple carriers can sometimes achieve better pricing or broader coverage for a specific line, but it creates administrative complexity and potential coordination issues. Monoline placements also mean separate renewal dates, separate billing, and no multi-line discounts — factors that affect both the client's total cost and the broker's servicing workload.
Real-World Example
A trucking company's commercial auto is placed with a specialty trucking carrier on a monoline basis because the rates are 25% better than any package option. Their general liability goes to a different carrier that specializes in transportation GL, and workers compensation is placed with the state fund. The broker manages three separate policies with three carriers but achieves the best overall coverage and pricing by splitting the lines.
Common Mistakes
- 1Splitting lines across carriers without considering the coordination of defense and coverage between monoline policies.
- 2Not managing separate renewal dates effectively, allowing monoline policies to renew without competitive marketing.
- 3Forgetting to update umbrella carriers when underlying monoline policies change carriers or limits.
