The relationship between the world’s largest stablecoin issuer and one of the most powerful figures in US commerce is under fresh legal and political scrutiny. A court filing alleges that Howard Lutnick, in his capacity as Tether’s banker through Cantor Fitzgerald, helped block legislation unfavorable to the company, while a White House aide reportedly pushed Tether’s preferred legislative measure before joining the firm.

Senators Elizabeth Warren and Ron Wyden have raised concerns about potential conflicts of interest tying Lutnick to Tether, centering on a loan the stablecoin giant made to Dynasty Trust A, a trust benefiting Lutnick’s children. The timing of that loan, which came shortly after Lutnick divested from Cantor Fitzgerald, is what has lawmakers asking pointed questions.

The Cantor-Tether connection

Cantor Fitzgerald holds a 5% stake in Tether and serves as custodian for Tether’s reserves. Lutnick disclosed this during his confirmation hearings in January 2025, when he was being vetted for his role in the administration.

Following Lutnick’s sale of his Cantor stakes for trust holdings in 2025, the Tether loan to Dynasty Trust A was filed in New York shortly after. Warren and Wyden’s letter, dated April 29-30, 2026, zeroed in on this sequence of events, essentially asking whether the financial entanglement between Tether and Lutnick’s family created a feedback loop where policy decisions and personal enrichment became uncomfortably intertwined.
