Financial Intermediaries and Their Services

Updated for the 2026-2027 CFA® Level I curriculum.

Financial intermediaries connect the parties who need capital, liquidity, or risk transfer with the parties who can provide it. This reading tests whether you can name each intermediary type and match it to the specific service it performs. After reviewing this note, you should be able to read a short market scenario and identify which intermediary is at work and why.

Key Takeaways About Financial Intermediaries and Their Services

• Financial intermediaries each perform one specific function: execution, liquidity, risk transfer, capital raising, or safekeeping.

• Brokers act as agents for clients. Dealers trade for their own account and earn the bid-ask spread.

• Securitizers pool assets, such as loans or mortgages, and issue new securities backed by those pools.

• Depository institutions accept deposits and extend loans, connecting savers with borrowers.

• Insurance companies transfer risk from policyholders to the insurer in exchange for a premium.

• Clearinghouses reduce counterparty risk by standing between buyers and sellers after a trade is agreed.

• Custodians safeguard client assets and handle recordkeeping, separate from any trading function.

What You Need to Know for CFA Level I

• Identify each major financial intermediary type from a short description of its activity.

• Distinguish a broker's agency role from a dealer's principal role.

• Explain the service a securitizer provides and why an institution would use one.

• Separate the risk-transfer function of insurance companies from the risk-reduction function of clearinghouses.

• Match a market scenario to the correct intermediary based on the service performed, not the firm's name alone.

• Explain briefly why intermediaries improve market efficiency and liquidity.

Major Types of Financial Intermediaries

CFA Level I groups financial intermediaries by the function they perform in the market, not by industry label. The main types are:

Brokers

Brokers act as agents. They execute orders on behalf of clients and do not take ownership of the securities traded. They also earn a commission for the service.

Exchanges and alternative trading systems

These venues bring buyers and sellers together and support price discovery. An exchange itself is not taking a trading position. It is providing the infrastructure for trades to occur.

Dealers

Dealers trade for their own account. They quote bid and ask prices, hold inventory, and provide liquidity to the market. Their profit comes from the spread between the prices at which they buy and sell.

Securitizers

Securitizers pool assets, such as mortgages, auto loans, or credit card receivables, and issue new securities backed by the cash flows from that pool. This process converts illiquid loans into tradable securities.

Depository institutions and other financial corporations

Banks and similar institutions accept deposits and use those funds to make loans. They connect savers who want a safe place for cash with borrowers who need financing.

Insurance companies

Insurance companies accept premiums from policyholders and agree to pay claims if a specified event occurs. This transfers risk away from the policyholder and onto the insurer.

Arbitrageurs

Arbitrageurs identify price differences for the same or similar asset across markets and trade to profit from that difference. Their activity helps prices converge, improving market efficiency.

Clearinghouses

A clearinghouse acts as the counterparty to both sides of a trade after execution. This guarantees settlement and removes the risk that one party fails to deliver cash or securities.

Custodians and trustees

Custodians hold client assets in safekeeping and handle recordkeeping, valuation, and settlement support. They do not make trading decisions for the client.

The Services Intermediaries Provide

Each intermediary type maps to a specific service. Grouping the services this way makes the distinctions easier to recall.

How to Match an Intermediary with the Service in a Scenario

CFA questions describe an activity and ask you to name the intermediary. Use three questions to work through the scenario:

1. Does the firm take ownership risk? If yes, it is likely a dealer, insurer, or securitizer. If no, it is likely a broker, exchange, or custodian.

2. Is the firm acting for a client or for itself? Agency activity points to a broker. Principal activity points to a dealer.

3. What problem is being solved? Raising capital or pooling assets points to a securitizer or investment bank. Reducing settlement risk points to a clearinghouse. Safekeeping points to a custodian.

Working through these three questions in order avoids the common mistake of matching on a familiar label instead of the actual function described.

Why the Distinction Matters Within Market Organization

Market organization and structure examines how participants, venues, and intermediaries fit together to move a trade from decision to settlement. Confusing a broker with a dealer, or a securitizer with a depository institution, breaks that chain of reasoning. Later readings build on this structure when they cover order types, trading costs, and market regulation. Getting the intermediary types correct here supports accurate reasoning in those later topics.

Worked Example

A pension fund needs to complete four separate tasks this quarter:

1. Sell 50,000 shares of a large-cap stock through its regular trading relationship.

2. Purchase catastrophe insurance to protect a real estate holding from hurricane damage.

3. Buy newly issued bonds backed by a pool of 3,000 auto loans originated by a regional bank.

4. Confirm that its recent options trades will settle even if the opposing party defaults.

Step 1: Match each task to a function.

Task 1 is agency execution. Task 2 is risk transfer. Task 3 involves a pool of loans converted into tradable securities. Task 4 is counterparty risk reduction after a trade is agreed.

Step 2: Match each function to an intermediary.

Task 1: broker. Task 2: insurance company. Task 3: securitizer. Task 4: clearinghouse.

The pension fund is using four different intermediaries in one quarter, each solving a different problem. None of these roles overlap. A broker cannot guarantee settlement, an insurer cannot pool auto loans into bonds, and a clearinghouse cannot execute the original stock trade. Matching function to intermediary, not label to memory, is the skill being tested.

Common Exam Traps

Confusing brokers and dealers

A firm that executes trades is not automatically a broker. If the firm is trading for its own account and quoting a bid-ask spread, it is a dealer.

Memorizing a label without applying it to the facts

Recognizing the word "investment bank" in a question does not tell you whether the scenario describes underwriting, securitization, or advisory work. Read the described activity, not the firm name.

Using a broader label when the question wants the specific type

Calling a securitizer simply a "bank" misses the tested distinction. The question wants the specific function: pooling assets and issuing new securities.

Giving a directional answer without the underlying reason

Saying "dealer" without noting that the firm takes principal risk and earns the spread leaves out the reasoning the exam is testing.

Practice Question

A regional bank pools 2,000 residential mortgage loans it originated and issues new bonds backed by the cash flows from these loans, selling the bonds to institutional investors. This bank is functioning primarily as which type of financial intermediary?

1. Broker

2. Securitizer

3. Custodian
