Margin Reference Benchmark Rates

Reference Benchmark Rates


IBKR's benchmark for each currency is the reference rate around which our credit, debit, stock loan and other interest rate linked calculations are determined. IBKR uses a combination of internationally recognized reference rates (such Fed Funds), bank deposit rates, and dynamic interbank rates determined from foreign exchange and money markets to calculate an IBKR Reference Benchmark rate.
