Formal index complaints​

While we strive to provide quality products and services, if you have a formal index complaint regarding our index products, please follow the procedure as outlined below. Please do not submit general questions via the complaints procedure below since they will not be sent to the right MSCI team which will result in unnecessary delay. For general questions about our equity indexes, please contact MSCI Client Service. For general questions about MSCI Private Real Assets Indexes, please contact the MSCI Real Estate Client Services team via realestate@msci.com.

A formal index complaint is an expression of dissatisfaction concerning any aspect of the benchmark determination process. MSCI treats all formal complaints seriously and has a number of procedures in place to ensure that formal index complaints are conducted in a timely and fair manner, in accordance with our Formal Index Complaint Handling Policy and Procedure:
