Regulation of Brokers and Investment Managers

Oversight of Financial Intermediaries
Brokers, dealers, investment managers, and other financial intermediaries are subject to strict regulation to protect investors and ensure the stability of the financial system. Regulatory requirements cover licensing, capital, conduct of business, and operational standards.

Licensing and Registration
Broker-dealer registration: In the US, broker-dealers must register with the SEC and become members of FINRA. Registration requires: minimum net capital, written supervisory procedures, compliance infrastructure, bonding.
Investment adviser registration: Advisers with assets under management above thresholds register with the SEC (Form ADV), smaller ones—at the state level. Registration as an adviser vs broker-dealer has significant implications for fiduciary duties and compensation structures.
Fit and proper: Individual professionals (associated persons) must pass exams (Series 7, Series 63, etc. in the US), background checks. Regulators may bar individuals for misconduct.
Mutual recognition: Cross-border business requires compliance with regulators of multiple jurisdictions. Some agreements allow mutual recognition, but full passporting is limited.

Capital Requirements
Net capital rule (Rule 15c3-1): Broker-dealers must maintain minimum net capital, calculated based on business type and risks. The rule is designed to ensure liquid assets for orderly liquidation.
Risk-based capital: Capital requirements increasing with the growth of proprietary positions, customer obligations. Haircuts are applied to various assets based on liquidity and volatility.
Investment adviser capital: Requirements are less stringent than for broker-dealers since advisers typically do not hold customer assets. Custody requirements separately regulate the safeguarding of client assets.

Conduct of Business Rules
Suitability: Broker-dealers must recommend only suitable investments based on the client's investment profile (objectives, risk tolerance, financial situation). FINRA Rule 2111 establishes the framework.
Regulation Best Interest (Reg BI): Introduced in 2020, this enhanced standard requires broker-dealers to act in the "best interest" of retail customers, going beyond suitability. It includes disclosure, care, conflict of interest, and compliance obligations.
Fiduciary duty: Investment advisers have a fiduciary duty—an obligation to act in the best interest of the client, duty of loyalty (putting the client first), duty of care (providing advice in accordance with professional standards).

Customer Protection
Segregation of assets: Broker-dealers must segregate customer securities and cash from firm assets. Customer Reserve Rule (15c3-3) requires maintaining a reserve account for customer obligations.
SIPC insurance: The Securities Investor Protection Corporation provides insurance for customer assets in case of broker-dealer failure. Coverage up to $500,000 (including $250,000 cash). SIPC does not protect against investment losses.
Customer complaints: Regulated firms must have procedures for handling complaints. Arbitration through FINRA is the usual mechanism for resolving disputes between customers and broker-dealers.

Compliance and Supervision
Compliance program: Regulated firms are required to have written supervisory procedures, designated compliance officers, ongoing training. The compliance function must have adequate resources and independence.
Surveillance: Firms must monitor trading activity for detection of manipulations, insider trading, suitability violations. Automated surveillance systems scan for patterns indicating misconduct.
Books and records: Detailed recordkeeping requirements—communications, orders, trades, customer information. Records must be retained for specified periods (5–7 years typically) and be available for regulatory examination.

Examinations and Enforcement
Routine examinations: FINRA, SEC, and state regulators conduct periodic examinations of regulated firms. Examiners review policies, procedures, records, and interview staff. Findings may lead to deficiency letters, enforcement referrals.
Enforcement actions: Violations can result in fines, censures, suspension or revocation of licenses, bars for individuals. Willful violations may have criminal consequences.
Cooperation: Cooperation with regulators during investigations can mitigate penalties. Whistleblower programs offer rewards for information on securities violations.

Technological Requirements
Cybersecurity: Regulators increasingly focus on cybersecurity programs. The SEC and FINRA have issued guidance on information security, incident response, notification requirements.
Business continuity: Firms must have business continuity plans for disasters, systems failures. Plans must ensure continuity of critical operations and customer access.
Algorithmic trading: Firms using algorithms for trading must have pre-trade risk controls, monitoring, kill switches. Market-wide circuit breakers and individual stock halts are exchange-level safeguards.
