Brokerage Account

A brokerage account holds cash and securities and records trades. Compare cash and margin accounts, control, fees, cash sweeps, protection, and risks.

A brokerage account is an account at a broker-dealer through which a customer can hold cash and securities, submit investment orders, receive transaction records, and use services permitted by the account agreement. The account is a legal and operational relationship, not an investment by itself: its risk depends on the assets held, borrowing, trading authority, cash arrangement, fees, and firm structure.

In the United States, the first major account distinction is usually cash versus margin. Other labels, such as individual, joint, retirement, custodial, trust, entity, self-directed, discretionary, or advisory, answer different questions about ownership, tax status, decision authority, or service model.

Key Takeaways

  • A cash account requires full payment for purchases; a margin account permits borrowing from the brokerage firm under the agreement and applicable requirements.
  • Margin can amplify losses, create interest expense, trigger additional equity requirements, and permit the firm to liquidate securities under the agreement.
  • A brokerage account does not guarantee access to every product, market, order type, research tool, or trading session.
  • The introducing firm, carrying firm, clearing firm, custodian, and execution venue can be different entities.
  • The customer generally decides what to buy or sell in an ordinary brokerage account; discretionary authority or an advisory account changes that control structure.
  • Uninvested cash may remain as a brokerage credit balance or move through a bank-deposit or money-market sweep, with different yield, liquidity, and protection features.
  • SIPC protection concerns missing customer cash and securities when a member brokerage firm fails; it does not protect against market loss, poor recommendations, or a security losing value.
  • Fees, spreads, product expenses, financing costs, and currency costs should be evaluated together.
  • Form CRS, BrokerCheck, the account agreement, margin disclosure, cash-sweep terms, fee schedule, confirmations, and statements provide the main evidence.

One firm may perform several steps, or an introducing broker may use another broker-dealer to carry accounts and clear transactions. Read the agreement and statement disclosures to identify the responsible legal entities rather than relying only on the app or brand name.

Cash Account vs. Margin Account

FeatureCash accountMargin account
Payment for purchasesCustomer pays the full purchase priceCustomer may borrow part of the purchase price from the firm
Loan and interestNo broker loan used to pay for account purchasesMargin debit generally accrues interest under the firm’s terms
CollateralNo margin loan merely from buying fully paid securitiesAccount assets secure the broker’s loan
Short sellingNot available as an ordinary cash-account activityConducted through a margin account, subject to approval and requirements
Loss exposureInvestment can lose some or all of its valueLoss can exceed the customer’s deposited amount, plus interest and other charges
Firm liquidation rightCash-account restrictions can follow payment or settlement violationsFirm can sell assets to address a margin deficiency under the agreement, potentially without advance notice
Key documentsCustomer agreement, payment and settlement termsCustomer agreement, margin agreement, margin disclosure, rate schedule, and house requirements

A cash account can hold both cash and securities. Its name means the customer must fully pay for purchases; it does not mean the account can hold only cash. Likewise, a margin account does not mean every position was purchased with borrowed money. Check the actual debit balance and transactions.

Worked Example: How Borrowing Amplifies a Loss

Assume an investor buys $10,000 of stock.

Cash account: The investor pays the full $10,000. If the position falls to $7,000, the unrealized loss is $3,000, or 30% of the amount invested.

Margin account: The investor contributes $5,000 and borrows $5,000 from the firm. If the position falls to $7,000, account equity before interest is:

$7,000 market value - $5,000 loan = $2,000 equity

The investor’s equity has fallen by $3,000, or 60% of the original $5,000 contribution. Interest increases the loss. If equity falls below regulatory or stricter firm requirements, the firm may demand additional assets or liquidate positions under the margin agreement.

The example ignores commissions, spreads, taxes, dividends, and changing interest. It demonstrates leverage, not a likely return or a recommendation to use either account.

Ownership, Tax Status, and Decision Authority

Several account labels can apply at the same time:

DimensionCommon examplesQuestion answered
Payment structureCash or marginCan the customer borrow from the broker for transactions?
Legal ownershipIndividual, joint, trust, estate, or entityWho owns the account and has legal authority?
Beneficiary structureCustodial or other beneficiary arrangementWho acts for another person and under what governing arrangement?
Tax frameworkTaxable or tax-advantaged accountWhich tax rules and contribution, distribution, or holding restrictions may apply?
Decision authoritySelf-directed, nondiscretionary, or discretionaryWho can decide to trade without obtaining transaction-by-transaction consent?
Service relationshipBrokerage or advisoryIs the core service transaction execution or ongoing advice and management?

Do not infer one dimension from another. A retirement account can be cash or margin-limited, self-directed or managed, and held through a brokerage or advisory service, subject to the program and applicable rules. Tax treatment and permitted activity vary by account and jurisdiction and require separate analysis.

Brokerage vs. Advisory Account

QuestionBrokerage accountAdvisory account
Core serviceAccepting and carrying out securities transactions and related brokerage servicesOngoing investment advice or portfolio management
Typical decision authorityCustomer generally makes final trade decisions unless valid discretionary authority is grantedAdviser may provide ongoing advice or exercise agreed discretion
Common compensationCommission, markup or markdown, account charge, margin interest, or other brokerage revenueAsset-based, fixed, hourly, performance-based where permitted, or another advisory fee
Main documentsForm CRS, brokerage agreement, fee schedule, confirmations, and statementsForm CRS, Form ADV, advisory agreement, fee schedule, and statements
U.S. conduct frameworkRegulation Best Interest for covered retail recommendations, plus other broker-dealer dutiesInvestment-adviser fiduciary framework for the advisory relationship

A firm can offer both relationships, and the same professional can act in different capacities. Determine which capacity applies to the specific account, recommendation, trade, and fee. A discretionary brokerage account is not automatically an advisory account, and an online interface does not necessarily mean the service is execution-only.

What the Account May Hold or Access

Depending on the firm and approvals, a brokerage account may provide access to stocks, bonds, mutual funds, exchange-traded funds, options, new issues, certificates of deposit, government securities, or other investments. Product access can be limited by:

  • account type and ownership;
  • customer eligibility and firm approval;
  • jurisdiction and residency;
  • product risk and disclosure requirements;
  • market, venue, and trading-session access;
  • minimum purchase or position size;
  • margin eligibility and house requirements; and
  • the firm’s product menu and operational capabilities.

The ability to hold a security does not mean the security is suitable, liquid, protected from loss, or available for immediate sale. Trading halts, market closures, settlement, restricted positions, transfer limitations, and thin markets can delay access to proceeds.

Uninvested Cash and Sweep Programs

Cash can enter a brokerage account through deposits, sales, dividends, interest, or distributions. The firm may leave it as a brokerage credit balance or move it automatically into a sweep vehicle.

Cash arrangementBasic structureProtection and review questions
Brokerage credit balanceCash remains owed within the brokerage relationshipReview use of free credit balances, interest terms, availability, and SIPC treatment
Bank-deposit sweepCash moves to one or more participating banksReview interest rate, allocation among banks, FDIC eligibility and limits, exclusions, and access
Money-market mutual fund sweepCash purchases shares of a money-market fundReview prospectus, yield, expenses, liquidity, and investment risk; it is not a bank deposit

The highest displayed cash rate may not apply to every balance or account. A sweep can also create compensation or affiliate conflicts. Check the default option, alternatives, rate methodology, program banks, limits, and what happens when cash exceeds applicable coverage.

Custody, Carrying, and Street Name

The customer-facing firm does not necessarily perform every account function. An introducing firm can establish and service the relationship while a carrying firm maintains the account records, holds customer assets under the applicable arrangement, processes transactions, and produces statements or confirmations.

Securities are often registered in street name, meaning the broker or its nominee appears as the registered holder while the customer is recorded as the beneficial owner on the firm’s books. This arrangement supports trading and settlement but makes accurate firm records and customer review important.

The exact division of responsibilities comes from the carrying agreement, account documents, confirmation, statement, and regulatory framework. A marketing brand, app provider, investment adviser, introducing broker, and carrying broker may be related or independent entities.

SIPC Protection Is Not Market-Loss Insurance

SIPC is a U.S. nonprofit membership corporation that can become involved when a SIPC-member brokerage firm fails and customer cash or securities are missing. Subject to the statute and current limits, the process seeks to return customer property or address qualifying customer claims.

SIPC does not protect:

  • a decline in a security’s market value;
  • a poor or unsuitable investment merely because it lost money;
  • promised investment performance;
  • every asset or transaction held through a financial platform;
  • cash unrelated to purchasing or selling securities; or
  • an account at a firm that is not a SIPC member.

Bank-deposit sweep balances may instead be eligible for FDIC insurance under the sweep program’s structure and current rules. Money-market mutual funds are securities, not insured bank deposits. Verify the legal entity, product, ownership category, program bank, and current coverage rather than treating a logo as proof that every balance is protected.

How to Evaluate a Brokerage Account

  1. Confirm the firm’s legal name and registration in FINRA BrokerCheck and relevant regulator databases.
  2. Read Form CRS for services, fees, conflicts, conduct standards, and disciplinary-history prompts.
  3. Choose deliberately between cash and margin; do not assume the application’s default is appropriate.
  4. Confirm ownership, beneficiaries, authorized persons, trusted contact, and decision authority.
  5. Identify the introducing, carrying, clearing, custody, and cash-sweep entities.
  6. Compare the Brokerage Fee schedule, Commission terms, margin rate, currency costs, and product expenses.
  7. Review product, market, order-type, transfer, and withdrawal restrictions.
  8. Secure the account with available authentication and verified contact methods.
  9. Compare each confirmation and statement with instructions and report discrepancies promptly.

Risks and Common Mistakes

  • Market risk: Account protection does not prevent investments from losing value.
  • Margin risk: Borrowing can produce losses beyond deposited funds and forced liquidation without advance notice.
  • Cash-sweep risk: Default cash may earn less than alternatives or receive a different protection regime than expected.
  • Authority risk: Joint owners, agents, trustees, custodians, advisers, or discretionary managers may have different powers.
  • Firm-identity risk: The visible platform may not be the carrying broker, custodian, or SIPC member.
  • Liquidity risk: A sale can be delayed or costly because of market conditions, restrictions, halts, or settlement.
  • Cost risk: Zero commission can coexist with spreads, product expenses, account fees, margin interest, and currency costs.
  • Fraud risk: Impostors can misuse a real firm’s name, website design, or registration details.
  • Tax error: An account label does not answer the tax result of a contribution, trade, transfer, income item, or withdrawal.
  • Documentation error: Ignoring confirmations and statements can allow unauthorized activity or processing errors to persist.

Authoritative Sources

  • Brokerage Firm: Customer-facing or operational firm providing one or more brokerage functions.
  • Broker-Dealer: Regulated firm that can act as broker, dealer, or both.
  • Margin Account: Brokerage account in which the firm can extend credit secured by account assets.
  • Brokerage Fee: Transaction, account, platform, transfer, and service charges.
  • Clearing Broker: Firm performing defined clearing, settlement, or carrying functions.
  • Custodial Account: Account controlled by a custodian for a beneficiary under the governing arrangement.

FAQs

What is the difference between a cash and margin brokerage account?

In a cash account, the customer must pay the full purchase price. In a margin account, the broker can lend money secured by account assets, which adds interest, margin requirements, forced-liquidation risk, and the possibility of losing more than the amount deposited.

Who makes investment decisions in a brokerage account?

The customer generally makes the final decisions in an ordinary nondiscretionary brokerage account. Another person can act only under valid authority, and an advisory or discretionary arrangement should be documented separately.

Is cash in a brokerage account FDIC-insured?

Not automatically. Cash placed through an eligible bank-deposit sweep may receive pass-through FDIC insurance under the program’s rules and limits. A brokerage credit balance or money-market mutual fund follows a different protection framework.

Does SIPC protect brokerage accounts from investment losses?

No. SIPC addresses qualifying missing cash and securities when a member brokerage firm fails. It does not reimburse ordinary market losses or guarantee investment performance.

Can a brokerage firm sell securities without permission?

In a margin account, the agreement can permit the firm to liquidate securities to address a deficiency, potentially without advance notice. Other valid authority, legal process, or account restrictions can also matter. Review the specific agreement and facts.
