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. Formal index complaints include complaints regarding whether a specific index appropriately represents the market, segment or strategy it seeks to measure, complaints regarding a proposed change to the index determination process, complaints regarding an application of the methodology in relation to a specific index determination, and complaints regarding other decisions in relation to the index determination process.

Formal index complaints must be submitted through the web form found here.

MSCI’s formal index complaints policy can be found here (PDF). For the avoidance of doubt, this process covers formal index complaints only. 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.
