Interest and Financing

Interest Schedule


Interactive Brokers calculates an internal funding rate based on a combination of internationally recognized reference rates on overnight deposits (ex: Fed funds, LIBOR), bank deposit rates, and real-time market rates from the world's largest and most liquid market, the interbank short-term currency swap market.

While central banks and major money-center banks set and publish reference rates for interest dependent investments, these rates often do not reflect the exact investment costs/opportunities seen in interbank and commercial transactions. IBKR's interest model starts with the reference rates and incorporates the dynamic market pricing to produce a midpoint or "benchmark".

IBKR adds a spread around the benchmark to determine deposit and borrowing rates applicable to client balances in each currency. Spreads are tiered such that larger balances receive more favorable interest treatment due to smaller spreads around the benchmark.


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 as LIBOR, Fed Funds, etc), bank deposit rates, and dynamic interbank rates determined from foreign exchange and money markets to calculate an IBKR Reference Benchmark rate.

IBKR accrues interest on a daily basis and posts actual interest monthly on the third business day of the following month. For detailed examples on how we calculate interest, open the Interest Paid to You and Interest Rates Charged to You on Margin Loan Balances sections on this page.


Interest Paid on Idle Cash Balances

Client accounts are eligible to receive credit interest on long settled cash balances in their securities accounts.

Accounts with a Net Asset Value (NAV) of USD 100,000 (or equivalent) or more are paid interest at the full rate for which they are eligible. Accounts with NAV of less than USD 100,000 (or equivalent) will receive interest at rates proportional to the size of the account. For example, an account with a NAV of USD 50,000 will earn credit interest at a rate equal to one-half the rate paid by IBKR to accounts with a NAV of USD 100,000 or more.

Interest accrues and is payable on a daily basis. IBKR posts the interest payments on a monthly basis on the third business day of the following month.

IBKR uses a blended rate based on the tiers outlined in the table below. The tiers on which interest rates are based are subject to change without prior notification.

For balances held in CHF, DKK, EUR, JPY or SEK, IBKR currently applies an effective negative rate to long balances held. The negative rate applied to accounts holding these currencies is the same regardless of account size. For other currencies in which the benchmark rate plus the interest rate paid is less than zero, the interest paid is 0%.

Higher Interest Rates for Large Cash Balances

We pay interest to clients for credit balances, based upon rates available in the interbank deposit market. For those clients that hold large cash balances in multiple currencies, we offer the ability to take advantage of the Forex Swaps market to potentially earn higher rates. This program is not designed for and would not benefit any client who holds a single-currency long balance. The mechanics behind this program involve the buying of a currency for settlement one day out and the selling of the same currency two days out, the difference in value between the two settlement dates being the interest earned. We automatically keep rolling the swaps until you no longer meet the minimum balance criteria, or you instruct us to halt the program. You must have at least USD $10 million in cash, and US residents must be Eligible Contract Participants (ECP) to enroll in the program.

For more information please contact our swaps desk at FXSwaps@IBKR.com or refer to our Knowledge Base.

Interest Charged on Margin Loans View Examples

When calculating rates, keep in mind that IBKR uses a blended rate based on the tiers below. For example, for a balance over 1,000,000 USD, the first 100,000 is charged at the Tier I rate, the next 900,000 at the Tier II rate, etc. When determining the quoted spread, IBKR will use the set benchmark rate or a benchmark rate of 0 for all benchmark rates less than 0.

IBKR accrues interest on a daily basis and posts actual interest monthly on the third business day of the following month.

The tiers on which interest is based may change from time to time without prior notification to clients. Such adjustments are done periodically to adjust for changes in currency rates.

  1. A minimum floor of 0.75% will be charged on all USD margin loans. Rates subject to change.
  2. May be subject to a 1% surcharge applied to the spread if financing is not pre-arranged.
Disclosures
  1. Credit balances greater than USD 10,000 (or equivalent) in accounts with a NAV of less than USD 100,000 (or equivalent) will be paid interest at a proportional rate. For accounts holding credit balances in currencies carrying a negative interest rate, the negative rate will be applied to accounts with balances of at least USD 100,000 (or equivalent), but smaller credit balances will not be charged the negative rate.
