What Is an Initial Margin?

An initial margin is the minimum amount that an investor must deposit with a broker or exchange to open a new position in a financial instrument like stocks, bonds, or futures contracts. This is essentially a down payment and it acts as a form of collateral to cover any potential losses from the trade. The exact amount of initial margin required can vary based on the specific financial instrument, market conditions, and the broker’s requirements.

In practical terms, the initial margin deposit makes it possible for investors to use borrowed funds to engage in trading, a practice commonly known as buying on margin. However, if the market moves against the investor, they may have to deposit additional funds to maintain the position, which is known as the maintenance margin.
