The head of the federal government agency that oversees Fannie Mae and Freddie Mac wants the mortgage giants to consider accepting a homebuyer’s cryptocurrency holdings in their criteria for buying mortgages from banks.

The regulator overseeing Fannie Mae and Freddie Mac on Wednesday ordered the housing giants to consider cryptocurrency as an asset for single-family mortgage loan risk assessments, a move that could potentially open the door to borrowers using crypto investments to qualify for home loans.

Fannie Mae and Freddie Mac were also directed to consider additional risk mitigants, including adjustments for market volatility.
