What is a wholesale insurance broker?
A plain-English definition for wholesale insurance producers, and for the retail producers they work with.
A wholesale insurance broker is an intermediary that places insurance for retail agents and brokers rather than for the insured directly. Wholesalers give retail agencies access to specialty and surplus lines markets, and the underwriting expertise to place hard-to-place risks. A wholesaler that can bind coverage for an insurer is usually called a managing general agent (MGA); one that cannot is often called a surplus lines broker.
How it works.
A business owner asks their retail agent for coverage. If the standard markets the retail agent works with decline the risk or the line is specialized, the retail agent sends a submission to a wholesaler. The wholesaler shops it to the insurers it has access to, negotiates terms, and returns quotes to the retail agent, who presents them to the client.
The wholesaler usually has the direct relationship with the insurer, and the retail agent keeps the relationship with the client. In a surplus lines placement, the licensed surplus lines broker (often the wholesaler) also handles state compliance, such as filings and premium tax. According to WSIA, wholesale brokers without binding authority remain the largest distributors of surplus lines products.
Why it matters to wholesale producers.
A wholesaler's business comes from retail producers. The number of submissions a wholesale producer sees depends on how many retail producers who write their lines know them, trust their appetite and think of them first. That makes retail producer relationships the core of wholesale growth.
For retail producers: a good wholesaler extends your market access to classes your standard carriers will not write, without you needing a direct appointment with each specialty insurer.

Questions.
What is the difference between a wholesale broker and a retail broker?
A retail broker works directly with the insured. A wholesale broker works with retail brokers and agents, placing their clients' risks with specialty and surplus lines insurers, and rarely deals with the insured directly.
Is a wholesale broker the same as an MGA?
Not always. Both are wholesale intermediaries, but an MGA holds binding authority from an insurer, while a wholesale broker without that authority submits risks to underwriters who make the binding decision.
Can a firm be both retail and wholesale?
Yes. The same firm can act as a retailer on one placement and a wholesaler on another.
