Why did I receive this message?

You received a message from IBKR on February 23, 2022 because your account traded spread trades on CME in (1) one or more of the following products between January 1, 2015 and late September 2021: E-Mini Equity index Futures (including Housing Index Futures); Micro E-Mini Index Futures; Micro E-Mini Index Options; and Nikkei Equity Futures, and/or (2) certain FX futures products between February 1, 2018 and mid-December 2021.

Why did I receive a credit?

As set forth in the message, certain spread trades in those products (see response #1) are subject to discounted CME exchange fees (as compared to outright trades in those products).  Your account traded spread trades in one or more of those products between January 1, 2015 and late September 2021 (or FX futures between February 1, 2018 and mid-December 2021) and, as a result of an inadvertent error, overpaid associated CME exchange fees.  IBKR has credited your account for the overpaid CME exchange fees. 

What do I need to do?

You will need to log into your account and withdrawal the funds.

Am I owed money for other trades?

Not that we have identified.  

How long do I have to withdraw the funds?

Please withdraw the funds within 30 days of the date of the message you received (by March 25, 2022).

The message I received says something about owing an outstanding debt to IBKR. What does that mean?

This means that your account owed an outstanding debt to IBKR, and the amount you received in reimbursement was credited against the outstanding debt amount. If the reimbursement amount exceeded the outstanding debt about, you received a credit and may withdraw the difference.
