Broker: intermediary who arranges transactions between parties

Core functions and characteristics

Typical broker tasks include identifying counter‑parties, presenting offers, advising on market conditions, and executing or arranging the exchange of goods, services or financial instruments. Brokers are commonly paid a fee or percentage of the transaction value; some receive a commission only when a deal completes, while others work on retainer or charge flat fees. A broker who also buys or sells for their own account becomes a principal rather than a purely neutral intermediary.

Common types of brokers

• Real estate broker — assists in buying, selling or leasing property and often manages listings and negotiations.
• Stockbroker / securities broker — places orders in financial markets and may provide research or advisory services.
• Insurance broker — compares policies from multiple insurers to find suitable coverage for clients.
• Mortgage broker — connects borrowers with lenders and helps arrange loan terms.
• Freight and customs brokers — coordinate shipping logistics and regulatory clearances.

Regulation, duties and conflicts

Brokers are often subject to licensing, registration and conduct rules that aim to protect consumers and ensure market integrity. In many jurisdictions a broker has a duty to disclose material information and to avoid conflicts of interest, though the precise fiduciary or agency obligations vary. The distinction between a broker and an agent is important: an agent acts on behalf of a principal, while a broker primarily facilitates transactions between parties. When a broker chooses to act simultaneously for opposing parties it may be called dual agency and is typically restricted or regulated.

History and modern development

Intermediaries have existed wherever trade occurs; over time the broker role specialized alongside the growth of financial markets and regulated commerce. Technological change, especially electronic trading platforms and online brokerages, has lowered some entry barriers and shifted pricing models from commission‑based to fee or subscription structures, while creating new regulatory and consumer‑protection questions.

Importance and practical considerations

Brokers provide access, market knowledge and administrative convenience that can be especially valuable for individuals and small firms. Choosing a broker requires attention to costs, disclosure of conflicts, service level, and whether the broker will act as an impartial intermediary or also take positions in the market. For introductory information about the broker’s role in transactions see buyer and seller relationships, and for typical compensation arrangements consult materials on commissions and fees.

Understanding the specific rules and customary practices in a given industry is essential: the label "broker" covers a range of functions from hands‑off matchmaker to active market participant, and that range determines legal status, responsibilities and appropriate consumer safeguards.
