Global Real Estate Fund Index (GREFI) Quarterly  

Published on 24 Mar 2026

The Global Real Estate Fund Index (GREFI) is jointly produced by INREV, ANREV and NCREIF and measures the performance of non-listed real estate vehicles on a global scale.

Please send feedback to bert.teuben@inrev.org, daisy.huang@anrev.org, or ddierking@ncreif.org

The GREFI is an index showing the performance of non-listed real estate funds on a global scale. The GREFI is updated on a quarterly basis and is published 12 weeks following the quarter end.

The aims of the GREFI are to improve transparency of real estate as an asset class and to help our members make better informed investment decisions. As an industry, it is vital that we work towards being able to make robust global and intra-regional comparisons.

This initiative represents the integration of three member-driven non-profit organisations to meet the data collection and information needs of their expanding global activities, and to serve as the basis for further collaboration in the future.
