Many of the applications on which the indices are based become closed mortgages securitized by U.S. federal government agencies, which makes the indices a valuable forward-looking indicator of new production for mortgage-backed securities.

In this way, mortgage traders, lenders, investors and portfolio managers can access a timely, data-driven indicator of U.S. mortgage purchase and refinance rates to help enhance economic forecasting and prepayment models, and for more precise risk management. The indices use rich transaction data from the ICE Mortgage Technology platform, which currently processes nearly half of all mortgages in the U.S.

Note: Data presented on this page reflects production as of close of prior business day.
