Credit Risk Transfer
Credit risk transfer (CRT) is a key part of our Single-Family and Multifamily business models. Through our credit risk transfer transactions, we facilitate the flow of private capital between Fannie Mae's lender customers and a diverse group of investors.
As the largest credit risk manager in the mortgage industry, we employ prudent standards and advanced technologies to acquire quality loans, prevent defaults, and reduce losses. We continuously evolve our CRT programs to broaden the types of loans covered and promote growth in the credit risk transfer market. Through our suite of credit risk transfer vehicles, we offer opportunities for investors to share in the credit performance of our book of business.
$2.23T of total unpaid principal balance of mortgage loans that have been partially covered by Single-Family CRT vehicles at issuance as of Q1 2021.
In addition to DUS risk sharing, $109.91B of total unpaid principal balance of Multifamily mortgage loans has been covered through MCAS and MCIRT as of Q1 2021.
