What is Collusion?
Collusion is a secret agreement between two or more parties to deceive, defraud, or gain an unfair advantage. Collusion typically harms competitors, clients, regulators, or the public. It involves deliberate coordination that one or more parties are obligated to prevent or disclose. In most regulatory and legal contexts, collusion is unlawful.
The act of colluding refers to the active participation in such an arrangement and knowingly coordinating with another party to achieve an outcome that would be prohibited if pursued openly.
Collusion in Financial Markets
In financial services, collusion most commonly involves traders, brokers, or counterparties coordinating to manipulate prices, fix rates, or share inside information for mutual benefit. Examples include:
- Rate-fixing — Traders at competing institutions agree to submit artificially aligned benchmark rate submissions. The LIBOR scandal is one of the most documented examples. Traders at major banks coordinated submissions to benchmark interest rate panels to benefit their own trading positions, affecting financial instruments worth trillions of dollars globally
- Front-running — A broker colluding with a counterparty to trade ahead of a large client order, profiting from the anticipated price movement. However, front-running can still be done on an individual basis and does not require “collusion.”
- Bid-rigging — Competing firms coordinating on auction or tender submissions to predetermine the winner and inflate prices
- Information sharing — Traders at separate institutions exchanging material non-public information to coordinate trading strategies in violation of market abuse rules
These behaviors are prohibited under antitrust laws and market abuse regulations, enforced by authorities such as the DOJ, FTC, SEC, FINRA, and FCA, as well as frameworks including MAR and elements of Dodd-Frank.
How Collusion Appears in Communications
Collusion rarely happens in person. It leaves a trail in chat messages, emails, voice calls, and encrypted messaging apps. Phrases signaling coordination, unusual communication patterns between counterparties, and conversations that reference deals, prices, or positions outside normal channels are all indicators that surveillance programs are designed to detect.
This is why communications surveillance is central to collusion detection. AI-powered platforms analyze individual messages and relationship patterns, timing, and context. This holistic analysis surfaces coordination that keyword searches alone would miss.
Collusion in Other Contexts
Economics
In competition law and economics, collusion refers to agreements between firms to restrict competition. Whether explicit or tactical, price-fixing cartels are the most common form. The FTC and Department of Justice actively prosecute collusive arrangements under US antitrust law.
Academic Integrity
In educational settings, collusion refers to unauthorized collaboration between students on assessed work, presenting jointly produced work as individual effort. It is treated as a form of academic misconduct distinct from plagiarism.
