Senator Richard Blumenthal has sent a letter to Cantor Fitzgerald's CEO demanding details on the firm's partnership with stablecoin issuer Tether. The request lands as Democrats eye a Senate majority and push harder on crypto‑related security issues.
Blumenthal's letter, addressed to Brandon Lutnick, the son of Commerce Secretary Howard Lutnick, asks for records on how Cantor monitors Tether's compliance with banking and sanctions rules. He also wants every communication involving Howard Lutnick about Tether, even after the elder Lutnick left Cantor to join the Trump administration in 2025. The senator frames the inquiry as a national‑security matter, writing that:
"Disturbingly, Cantor Fitzgerald's lucrative business arrangements with Tether come at the expense of America's national security." (Cointelegraph)
Financial stakes
- Cantor bought a 5 % stake in Tether in April 2024. At that time the stake was valued around $600 million.
- By the time Blumenthal wrote his letter, the same stake was estimated at $10 billion, a ten‑fold jump that coincides with the return of Trump to the White House. (Cointelegraph)
- Howard Lutnick is alleged to have received more than $250 million from the partnership, including a $192 million distribution from Cantor. (Cointelegraph)
Tether itself says it has been cooperating with law‑enforcement for years and has frozen nearly $550 million in Iran‑linked USDT this year. (Cointelegraph)
"Just as Tether has made untold millions in interest and investments from the stablecoins used in these illicit activities, so has Cantor Fitzgerald profited from its relationship with Tether." (Cointelegraph)
Beyond the money, the probe asks whether Cantor requires independent audits of Tether, whether it ever considered ending the partnership, and what steps it has taken to investigate alleged sanctions evasion. Blumenthal also wants details on any loans or financing Tether may have provided to the Lutnick family to facilitate the transfer of ownership to Brandon and his brother. The deadline for a response is Oct 23. (Cointelegraph)
Conflict‑of‑interest concerns
A firm that holds and manages tens of billions of Tether's U.S. Treasury‑bill reserves is now run by the son of a sitting Commerce Secretary. The arrangement blurs the line between private profit and public policy.
If the Senate gains a majority, we could see a more aggressive oversight stance that forces firms like Cantor to disclose more granular data or even unwind certain relationships.
Potential market impact
A crackdown on Cantor could tighten the supply chain for stablecoin reserves, potentially prompting Tether to look for alternative custodians. That shift might affect liquidity for traders who rely on USDT for arbitrage and hedging, and could encourage other stablecoin issuers to reassess their reserve‑management partners.
The letter is a formal step, not a subpoena, and Cantor has not yet responded. The Senate's Permanent Subcommittee on Investigations has a track record of digging deep, but political will can shift quickly. For now, the story adds another layer of uncertainty to an already volatile crypto regulatory environment.
