Loans to and from Customers

The rules on borrowing and lending between securities professionals and their customers are one of the most frequently tested topics on the Series 63. The critical distinction is between agents (absolute prohibition) and investment advisers (limited exceptions).


Agents - Absolute Prohibition

An agent:

  • May never borrow money or securities from a customer
  • May never lend money or securities to a customer
  • May never act as custodian for a customer's money, securities, or executed stock powers
  • There are NO exceptions - not for family members, not for financial institutions, not for affiliates

This is a bright-line rule with zero flexibility.


Investment Advisers - Limited Exceptions

Investment advisers (IAs) have a more nuanced set of rules. Borrowing and lending are generally prohibited, but there are specific exceptions.

When an IA May Borrow from a Client

The client must be one of the following:

  • A broker-dealer (BD)
  • An affiliate of the investment adviser
  • A financial institution engaged in the business of loaning funds

When an IA May Lend to a Client

One of the following must be true:

  • The IA is a financial institution engaged in the business of loaning funds, OR
  • The client is an affiliate of the investment adviser

All other borrowing or lending by IAs from or to clients is prohibited.

Exam Tip: Gotchas

  • Common trap: "An agent's client is a bank. May the agent borrow from the client?" The answer is no. The financial institution exception applies only to IAs, not to agents. Agents face an absolute prohibition regardless of who the client is.
