What is the availability of margin loans?

Margin loan availability refers to the balance in a margin account that is presently accessible to purchase securities on margin or for withdrawal. A margin account provides the client of a brokerage firm with access to loans secured by the client’s securities in the margin account.

The Operation of Margin Loan Availability

The availability of margin loans indicates to a brokerage firm client the amount of funds available for purchasing securities on margin and withdrawing funds from their margin account. Since the securities must be sufficient to cover the amount made available for the loan, the amount of money that becomes available for the loan fluctuates in tandem with the value of the securities in the account. If the value of the customer’s securities declines, the availability of margin loans also decreases.

Margin loan availability is applicable in the following two situations:

  • It indicates the monetary value in a margin account presently accessible for acquiring securities. This represents the proportion of the current account balance accessible for future margin purchases on new accounts.
  • It indicates the monetary value that can be withdrawn from an account while existing marginal positions are being held as collateral.

The availability of margin loans is subject to daily fluctuations due to the value of margin debt, which comprises acquired securities. However, pending transactions between the trade and settlement dates might need to be reflected.

A maintenance requirement on margin accounts, expressed as a percentage of the aggregate market value of the securities acquired on margin, is a mandatory obligation for brokerage firms. If the equity in an investor’s account, representing the margin loan availability amount, decreases below the maintenance margin, the investor may be subject to a margin call. A margin call is a formal request to liquidate a portion of the marginal securities or make an additional cash deposit into the account. Typically, this occurs within three days. The Securities Exchanges regulate margin trading, the Federal Reserve Board, and self-regulatory organizations (SROs) such as the Financial Industry Regulatory Authority (FINRA). However, brokerage firms may also establish more stringent requirements independently.

Illustration of Margin Loan Accessibility

Consider Bert M. to be a client of Ernie’s brokerage firm. Bert possesses a margin account that is stocked with securities. Bert advances funds from Ernie’s brokerage firm against these securities as collateral to purchase or withdraw funds from the account.

A margin loan is the money borrowed from Ernie’s firm to purchase these additional securities or for a withdrawal. The present value of the securities Bert has pledged as collateral determines Bert’s available margin loan amount at any given time, or “availability.”
