Most market watchers rely on the monthly margin debt figures published by Wall Street’s self-regulator, FINRA, as the reliable gauge in determining how much of securities trading on Wall Street is being done with borrowed money, known as margin debt.

According to the FINRA data, as of March 31, 2024, margin debt stood at $784.136 billion.
