币界网报道：The U.S. Federal Housing Finance Agency (FHFA) has issued new guidelines prohibiting Fannie Mae and Freddie Mac from accepting mortgages collateralized by cryptocurrency assets. The directive, announced on Wednesday, explicitly bars the government-sponsored enterprises from purchasing or guaranteeing any loans where digital assets serve as primary collateral. FHFA Director Sandra Thompson stated the move aims to "ensure the safety and soundness of the enterprises" amid crypto market volatility. The policy follows growing concerns about crypto-backed lending products that emerged during the 2021-2022 bull market, some of which collapsed during last year's market downturn. While not banning all crypto-related mortgages, the guidance significantly limits how borrowers can use digital assets in real estate financing through these major housing market channels. Industry analysts note this could impact alternative lending platforms that had been exploring crypto-mortgage products targeting traditional housing finance systems.
