Fannie Mae and Freddie Mac have begun placing sizable orders to purchase mortgage-backed securities (MBS), stepping into a market roiled by widening bond spreads amid a surge in volatility, according to a person with direct knowledge of the matter.

This activity signals a significant shift in the MBS market, where government-sponsored enterprises (GSEs) typically act as buyers of last resort. The widening spreads indicate increased investor caution, likely driven by concerns over economic growth and interest rate sensitivity. By aggressively acquiring MBS, Fannie and Freddie are attempting to stabilize prices and provide liquidity, which could ease borrowing costs for homeowners and mortgage lenders.

The move underscores the GSEs' ongoing role in supporting the housing finance system, particularly during periods of market stress. While the exact scale of their purchases remains undisclosed, the sheer size of their bids suggests a deliberate effort to influence the market. This intervention may help prevent further deterioration in MBS valuations, though it remains to be seen how investors will react to the GSEs' increased presence.
