The ORF is an exchange fee which OCC collects from its clearing members, including IBKR. Its stated purpose is to assist in offsetting exchange costs relating to the supervision and regulation of the options market (e.g., routine surveillance, investigations, and policy, rule-making, interpretive and enforcement activities). The fee was initiated by the CBOE in mid-2009, by each of the BOX, ISE and PHLX in January 2010, by AMEX and ARCA in May 2011, by Nasdaq in January 2012, by C2 in August 2012, by Miami in January 2013, by ISE GEMINI in August 2013, by BATS in February 2015, by Nasdaq BX in February 2016, by BATS EDGX in February 2017, by PEARL in February 2017, by MERCURY and EMERALD in February 2019, and MEMX in September 2023. As of January 1, 2024, it is assessed to customer orders at a rate of $0.02685 per U.S. exchange listed option contract with the rate per exchange as follows: 

Note that the ORF is assessed on all trades, both buys and sells, in addition to the IBKR commission charge as well as any existing exchange fees (e.g., liquidity removal) and will be reflected on the Activity Statement as a Regulatory Fee.

An account will be subject to interest charges despite maintaining an overall net long or credit cash balance under the following circumstances: 

1. The account maintains a short or debit balance in a given currency.

For example, an account maintaining a net cash credit balance equivalent to USD 5,000 comprised of a long USD balance of 8,000 and a short EUR balance equivalent to USD 3,000 would be subject to an interest debit based upon the short EUR balance.  There would be no offsetting credit on the long USD balance as it is less than the USD 10,000 Tier I level above which interest is earned.  

Account holders should note that in the event they purchase a security which is denominated in a currency that they do not hold in their account, IBKR will create a loan in that currency in order to settle the trade with the clearinghouse. If one wishes to avoid such loans and their associated interest charges, they would need to either deposit funds denominated in that particular currency or convert existing cash balances via the Ideal Pro (for balances of USD 25,000 or above) or odd lot (for balances less than USD 25,000) venue prior to entering into your trade. 

2. The credit balance is comprised  principally of proceeds from the short sale of securities. 

For example, an account maintaining a net cash credit balance of USD 12,000 which is comprised of a USD debit of 6,000 in the security sub-account (less the market value of any short stock positions) and a short stock market value credit of USD 18,000 would be charged interest on the Tier 1 debit of USD 6,000 and would earn no interest on the short stock credit as it falls below the USD 100,000 Tier I level.

3. The credit balance includes unsettled funds.

IBKR determines interest debits and credits solely based upon settled funds. Just as an account holder is not assessed interest charges on funds borrowed to purchase a security until such time that purchase transaction settles, the account holder will not receive an interest credit, or offset against a debit balance, on funds originating from the sale of a security until such time the transaction has settled (and IBKR has been credited funds by the clearinghouse).

While there is no provision for dormant or inactive account status, there is no monthly minimum activity requirement or inactivity fee in your IBKR account.

While we have no minimum account balance, should the account balance fall below USD 2,000 IBKR is precluded, by regulation, from affording margin treatment to securities positions. In addition, account holders will also be billed for any market data subscriptions maintained and, as a matter of policy, will have subscriptions terminated automatically when the account balance falls below USD 500.
