Senator Blumenthal probes ties between Tether and Cantor Fitzgerald
Key Summary
US Senator Richard Blumenthal has released a staff report alleging that Tether's USDT has become a primary payment rail for Iran-linked networks and sanctioned entities tied to terrorist proxies. The report also highlights Tether's relationship with Cantor Fitzgerald, which holds a 5% equity stake in the company and manages a substantial portion of its US reserves. Blumenthal is pressing for investigations into Tether's operations and potential self-dealing, raising concerns about the stability of the USDT market.

Background
The world's dominant stablecoin is back in the congressional spotlight, and this time Wall Street is in the frame too.The Report
Senator Blumenthal's staff reviewed 846 wallets designated by two bodies: the US Treasury's Office of Foreign Assets Control (OFAC) and Israel's National Bureau for Counter Terror Financing. The review window ran from June 2021 to August 2026. The headline figure: 84% of those wallets relied heavily on USDT. That made Tether's token the predominant asset moving through the flagged addresses.The Cantor Angle
Cantor Fitzgerald holds a 5% equity stake in Tether. The firm also manages a substantial portion of Tether's US reserves, which are estimated above $100 billion. Blumenthal is pointing to concerns over potential self-dealing tied to those connections. The worry, as framed in the report, is that a firm with both an ownership interest and a custodial role may not be the most neutral party when it comes to scrutinizing how the product is used.Next Steps
Blumenthal is formally asking Treasury Secretary Scott Bessent and Attorney General Todd Blanche to open inquiries into Tether's operations. His focus is on two areas: sanctions compliance and anti-money laundering practices. Tether says it cooperates with law enforcement. The company claims it helped freeze around $550 million in Iran-affiliated USDT during 2026.Market Implications
For traders and investors, the immediate question is whether these requests turn into formal action. A letter from a senator is not an indictment, and Treasury and the Justice Department have not announced any investigation in response. The research flags that investors may respond with increased caution, particularly those with heavy USDT exposure. The research notes that heightened scrutiny may affect USDT's liquidity and adoption among institutional investors.#Tether#USDT#Iran#CantorFitzgerald#SEC
