The Consumer Federation of America and the National Consumer Law Center submitted a letter to Congress and the Federal Housing Finance Agency, making clear that mortgage underwriting based on crypto assets has no place in government-backed markets. These products are volatile and risky, and any inclusion of these products should be relegated to the private market. This proposal will expose taxpayers to increased risk of losses, open the door to new forms of predatory and unsafe lending targeted at vulnerable borrowers, and ultimately threaten the safety and soundness of the Enterprises and the broader financial system.
