Senator Elizabeth Warren, Ranking Member of the U.S. Senate Committee on Banking, Housing and Urban Affairs, sent a letter to Securities and Exchange Commission Chairman Paul S. Atkins requesting information on how the SEC will protect investors after President Trump’s executive order cleared the way for pension funds and retirement accounts to hold cryptocurrency assets. The letter, issued as the committee negotiates crypto market structure legislation, warns the draft bill could create a “tokenization loophole” that lets financial products offered on the blockchain sidestep SEC authority and, combined with the executive order, further expose 401(k) savings to volatile crypto assets. Warren asks how the SEC will ensure fair valuation of crypto assets, assess manipulation and deceptive practices in crypto markets, and raise retail investor awareness, particularly for individuals gaining exposure through retirement plans; the AFL and AFT labor unions have previously opposed the committee’s draft bill. Warren requested responses by 27 January 2026.
