MIAC Analytics | Mortgage Industry Medians(MIMs) is a semi-monthly dealer consensus of long-term prepayment projections. MIMs™ is predicated upon MIAC selected Generic Cohorts with specific attributes including product type, coupon, and issue year of the largest populations in the MBS market.  The MIMs™ survey produces a Median value for base case consensus projections as well as consensus projections assuming immediate and sustained parallel shifts in the yield curve of user set increments.

Features include:

  • Automatic integration into MIAC Analytics; many mortgage assets, including MSRs and CMOs, are priced with dealer consensus prepayments as the assumption for future prepayment behavior.
  • Explicit loan attributes for each Generic Cohort, such as: WAC, WALA, WAM, mtm-LTV, FICO and Average Loan Size.
  • MIMs users can also elect to subscribe to Dynamic MIMs™, which enables users to forecast a dealer consensus prepayment forecast for given changes in mortgage rates.
