ICE U.S. Residential Mortgage Rate Lock Indices track mortgage rates and other statistics on U.S. residential mortgage loan applications where borrowers and lenders have committed to lock-in the interest rate prior to close. 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 hedging. The indices use rich transaction data from the ICE Mortgage Technology platform, which currently processes nearly half of all mortgages in the U.S.
Our methodology
Using a data-driven methodology based on loan applications from ICE Mortgage Technology, the ICE U.S. Residential Mortgage Rate Lock Indices track the average rate at which new residential home loans are locked each day.
The indices are calculated daily for all U.S. bank business days, with index data available the morning of the next business day. ICE U.S. Residential Mortgage Rate Lock Index data is available on the ICE Index Platform and via direct data feeds.
