Is the MBS market continuing to expand?

Ginnie Mae announced its mortgage-backed securities (MBS) portfolio grew to $2.74 trillion in April 2025. In addition, it has issued $42.2 billion in new MBS issuance, driving a net portfolio growth of $10.6 billion.
The government corporation, established by Congress in 1968, has a mission to expand affordable homeownership opportunities, particularly for first-time buyers. Ginnie Mae MBS programs support housing finance programs administered by the Federal Housing Administration, the US Department of Veterans Affairs, the US Department of Housing and Urban Development’s Office of Public and Indian Housing, and the US Department of Agriculture’s Rural Housing Service.
So far this year, Ginnie Mae has facilitated the pooling and securitization of loans for 205,000 first-time homebuyers, a news release highlighted.
April’s issuance included $40.7 billion in Ginnie Mae II MBS and $1.4 billion in Ginnie Mae I MBS, with $1.3 billion specifically designated for multifamily housing loans. These securities supported more than 125,000 households last month, including 58,000 first-time homebuyers.
According to recent portfolio data, as of March, Ginnie Mae guaranteed loans for over 11.7 million borrowers, including 7.27 million through the Federal Housing Administration, 3.71 million through Veterans Affairs programs, and 765,888 through the Rural Housing Service.
“Ginnie Mae securitization provides a unique and sustainable service in making homeownership more affordable, accessible, and equitable for our nation,” according to company documents. The organization’s focus remains on supporting low and moderate-income borrowers, rural communities, and underserved populations.
Ginnie Mae’s impact extends beyond single-family homes. The corporation supports approximately 1.33 million apartment homes and nearly 500,000 healthcare living units nationwide, aiming to address critical shortages in affordable rental housing.
Additionally, the corporation has played a vital role in preventing foreclosures, facilitating over 780,000 loan modifications and 860,000 partial claims for borrowers facing financial difficulties.
