Mission Index: Unique insights into socially aligned MBS
In response to increased investor interest in allocating capital to support affordable housing, Fannie Mae developed the Mission Index. Fannie Mae is uniquely positioned to provide information about the underlying characteristics of mortgages it acquires. The insights provided by this innovative disclosure solution allow investors to identify mortgage-backed securities (MBS) with high concentrations of loans that align with the mission objectives of Fannie Mae.
The Mission Index scores each MBS across three dimensions:
Income
Income criteria identify loans made to low-income borrowers or to finance affordable rentals.
Borrower
Borrower criteria include whether a borrower is a first-time homebuyer, in an underserved market, or part of a Special Purpose Credit Program.
Property
Property criteria determine whether the property is in a high-needs rural area, a minority tract, a low-income census tract or a designated disaster area, or whether the property is manufactured housing.



The Mission Index methodology measures how many loans in a pool meet at least one index criteria (the Mission Criteria Share) and how many index dimensions are met, on average, for all loans in the pool (the Mission Density Score).
Importantly, aggregating sensitive loan data into rolled-up metrics helps to preserve the privacy of individual borrowers. A well-understood historical correlation between the criteria attributes and loan prepayments also gives investors additional insights into likely relative security performance. Investing in high-scoring Mission Index pools will allow investors to support GSE mission lending activities while potentially benefiting from more stable prepayments.

Fannie Mae's Mission Index and Single-Family Social Bond Framework have significantly increased market transparency by providing pool-level insights into the underlying loans in collateral pools.

The Social Bond framework is credible and impactful.

The framework is aligned to the International Capital Markets Association's Social Bond Principles and the United Nations Sustainable Development Goals.
Validated
It is validated by a second-party opinion from Sustainalytics, a leading independent global provider of ESG and corporate governance research and ratings.
Transparent
Transparent annual impact reporting on the social impact of the loans underlying the bonds further bolsters investors' ability to establish how the bonds align with portfolio objectives.
Fannie Mae's Social Bonds are designed to attract more global capital to support affordable housing in the US. Growing investor demand for these mission-aligned MBS may also motivate lenders to deploy more capital to previously underserved markets.
