ABN AMRO Clearing USA (AAC USA), formerly ABN AMRO Chicago LLC (AACC) is a futures commission merchant and broker-dealer with memberships on all major exchanges. It clears exchange-listed futures, equities and options.[1] In January 2023, the name of the firm was changed to ABN AMRO Clearing USA from ABN AMRO Clearing Chicago LLC to better reflect the growing reach of its business.[2]

Beginning in the 1980’s when the first options exchange in Europe was started in Amsterdam, the company has grown into a leading global securities services provider. Operating for many years under the “Mees Pierson” and “Fortis” brands, they were rebranded as ABN AMRO Clearing following the July 1, 2010 merger between ABN AMRO Bank and Fortis Bank Nederland.[3]
