Margin

Margin is a loan your broker extends to you, secured against the assets in your account. When you open a margin position, the broker requires you to deposit a minimum amount of your own capital upfront - this is called the initial margin. In the United States, Regulation T sets the baseline initial margin requirement at 50% of a security's purchase price, meaning you must fund at least half the position yourself. The broker funds the rest, and charges you a margin rate - an annual interest rate on the borrowed amount. According to current data, margin rates typically range from 5% to 12% per year depending on the broker, and interest compounds daily whether your positions are profitable or not.\n\nThere are two types of margin to understand. Initial margin is the deposit required to open and hold a position overnight. Intraday or day-trading margin - which is set by the broker rather than the exchange - is often lower, and applies only to positions opened and closed within the same trading session. For futures specifically, exchanges such as CME Group set baseline initial and maintenance margin levels using risk-based models, and individual brokers (known as futures commission merchants, or FCMs) may apply additional requirements on top of those minimums.\n\nIf your account value falls below a threshold known as the maintenance margin level, your broker will issue a margin call - a demand to deposit additional funds or close positions to restore the required balance. Failure to meet a margin call can result in the broker forcibly liquidating your positions, potentially at an unfavourable price. FINRA oversees margin account rules for US-regulated brokers; investors using brokers regulated by the DFSA in the Dubai International Financial Centre or the FCA in the UK should check the specific margin rules published by those regulators.

For expats in the GCC, margin trading is available through both onshore and offshore brokers - including DFSA-regulated platforms in the DIFC and FCA-regulated brokers accessed remotely. The key cost to monitor is the margin rate, which at 5% to 12% annually represents a significant drag on returns that compounds daily. On a leveraged position held for a full year, that interest cost accrues regardless of market direction. High-fee margin products sit in the same category as other leveraged structures: the cost of borrowing must be weighed carefully against any expected return before committing capital.\n\nExpats should also be aware that margin calls can force liquidations at short notice, including during periods of high regional or global volatility. There is no GCC-wide regulatory floor for margin rates - each broker sets its own rate within the framework of its home regulator. Before using margin, check the broker's published rate schedule, understand whether the regulator (DFSA, FCA, SEC, or other) provides any investor protection on margined accounts, and consider whether a straightforward unleveraged UCITS position achieves a similar exposure without the borrowing cost.
