How to read this table
Brokers set margin rates as a base rate plus or minus a spread that shrinks as the loan grows. Rates move whenever the Federal Reserve changes its target rate, so the date column matters. Several brokers repriced in mid-September 2026.
Cash yields vary even more. Some brokers sweep uninvested cash into a bank account paying close to nothing. Others put it in a money market fund or pay a competitive rate only to subscribers. Check which applies to your account type.
Futures don't use margin loans
Futures margin is a performance deposit, not a loan, so you pay no interest on it. The day-trade margins on each broker's page show how much cash a single contract ties up during the session.
