Introducing broker (IB)

Last updated: February 03, 2026

Quick definition

An introducing broker is an individual or organization that solicits or accepts orders for the purchase or sale of futures contracts, commodity options, retail off-exchange foreign exchange contracts, or swaps, but does not accept money, securities, or property from customers to margin, guarantee, or secure such trades.

An introducing broker acts as a middleman in derivatives markets, connecting customers with the services they need to trade futures, options, foreign exchange, and contracts. The most important feature that sets introducing brokers apart is that they cannot hold customer money or assets. Instead, they focus on customer service—finding clients, providing market analysis, and offering trading advice—while partnering with larger firms called futures commission merchants (FCMs) to handle all the financial operations.

This division of labor creates opportunities for smaller, specialized firms to offer sophisticated trading services without needing the massive amounts of capital and complex operations that FCMs require. Introducing brokers can concentrate on serving customers well and developing expertise in specific markets, while FCMs handle the money management and paperwork.

defines an introducing broker as someone who solicits orders for derivatives but cannot accept customer funds to secure those trades. This restriction on holding customer assets is the core legal distinction between introducing brokers and FCMs.

To operate legally, introducing brokers must register with both the and the , which oversees day-to-day compliance. Registration involves completing required forms, paying fees, and demonstrating that key personnel have passed relevant examinations. The process includes background checks and ongoing compliance with industry rules.

The regulatory system recognizes two different business models:

Independent Introducing Brokers maintain their own capital requirements and can work with multiple FCMs. They must keep at least $45,000 in capital and file regular financial reports with the NFA. This model gives firms more flexibility to serve diverse customers across different trading platforms, but requires them to meet ongoing financial and reporting obligations.

Guaranteed Introducing Brokers operate under a formal agreement where an FCM takes full responsibility for their operations. The FCM guarantees the introducing broker's activities, which means the introducing broker doesn't need to maintain separate capital requirements or file financial reports. However, all customer business must go through the guaranteeing FCM, creating a more integrated but less flexible relationship.

The guarantee arrangement can be terminated by either party with 30 days' written notice to all relevant regulators. When this happens, the guaranteed introducing broker must either find a new guarantor or meet the requirements to become independent.

Every introducing broker must have a contractual relationship with at least one FCM to handle customer trades. The FCM serves as the '' and provides all the essential infrastructure: accepting customer funds, executing trades on exchanges, processing transactions, maintaining , and ensuring compliance with regulations that require customer money to be kept separate from firm assets.

This arrangement allows introducing brokers to focus their resources on customer service, market research, and trading strategies while the FCM handles the complex operational requirements. FCMs typically charge introducing brokers based on trading volume, with fees varying by transaction type, exchange, and account size.

Independent introducing brokers often work with several FCMs to give customers access to different trading platforms or specialized products. Guaranteed introducing brokers must direct all business to their guaranteeing FCM.

Introducing brokers must follow comprehensive rules covering customer account procedures, order handling, complaint resolution, and staff supervision. Key compliance areas include:

  • programs that meet federal standards
  • Customer communications that must be reviewed and approved before use
  • Staff supervision ensuring all personnel maintain proper registrations
  • Record keeping of customer accounts and transactions
  • Risk disclosure to customers before opening accounts

The NFA requires annual ethics training for all staff and regular inspections of any branch offices. Firms must also maintain and information security programs.

Introducing brokers serve an important market function by making derivatives expertise available to customers who need professional guidance in complex markets. They allow smaller firms and specialists to provide derivatives services without the massive infrastructure requirements of FCMs.

Customers typically work with introducing brokers to access specialized research and market analysis, receive guidance on trading strategies and market conditions, get help with trading platform procedures, and obtain advice on using derivatives for hedging business risks.

This personalized service and expertise level often exceeds what customers can get from large discount brokers or institutional firms that may not focus on smaller accounts or specialized needs.

When evaluating introducing broker relationships, customers should understand that introducing brokers never hold customer assets—all funds go directly to the FCM. This provides transparency in custody arrangements while allowing access to the introducing broker's expertise.

Important factors to consider include verifying current registration status through the NFA's database, reviewing any disciplinary history, understanding which FCMs the introducing broker works with, and evaluating their expertise in relevant markets and trading strategies.

The choice between independent and guaranteed introducing brokers mainly affects supervisory structure and flexibility. Guaranteed arrangements may provide additional oversight but limit the introducing broker's ability to use multiple clearing firms, while independent brokers offer more flexibility but must demonstrate their own financial adequacy.
