Senator Blumenthal Investigates Cantor Fitzgerald's Banking Ties to Tether as Democrats Eye Senate Majority

Connecticut Senator Richard Blumenthal has launched a probe into the financial relationship between Wall Street firm Cantor Fitzgerald and Tether, the issuer of the world's largest stablecoin USDT. The investigation comes as Democrats gain momentum toward retaking the Senate.

Senator Richard Blumenthal, a senior Democrat on multiple Senate oversight committees, is investigating the banking relationship between Cantor Fitzgerald and Tether, according to sources familiar with the matter. The probe focuses on how the $140 billion stablecoin issuer maintains its U.S. financial ties despite ongoing regulatory uncertainty around digital assets.

Cantor Fitzgerald, led by CEO Howard Lutnick, has served as a key U.S. banking partner for Tether, helping the company manage portions of its massive reserve holdings. The relationship has drawn attention because Tether has faced years of questions about the composition and location of its reserves, which theoretically back each USDT token in circulation at a one-to-one ratio with the U.S. dollar.

Blumenthal's investigation carries particular weight as polling suggests Democrats could retake Senate control in the upcoming election cycle. A shift in the Senate majority would give Democrats expanded subpoena power and the ability to hold formal hearings on crypto industry practices. The Connecticut lawmaker has previously taken aggressive stances on tech regulation and consumer protection issues.

The probe comes at a delicate moment for Tether. While the company published attestations showing over $140 billion in assets, critics have long questioned whether those reserves are truly liquid and accessible in a crisis. Tether has never undergone a full independent audit, instead releasing quarterly attestations from accounting firms that stop short of a comprehensive examination.

Cantor Fitzgerald's role is crucial because major U.S. banks have largely refused to work directly with crypto companies, especially stablecoin issuers. The firm's willingness to bank Tether has provided the stablecoin with a vital link to the traditional financial system. According to industry estimates, Tether processes over $50 billion in daily trading volume across crypto exchanges worldwide, making it the liquidity backbone of digital asset markets.

For individual crypto holders and traders, the investigation introduces regulatory risk into what many consider the safest corner of the digital asset ecosystem. USDT is widely used as a dollar substitute on exchanges, for cross-border payments, and as a stable store of value in volatile markets. Any disruption to Tether's banking relationships could trigger a depegging event or liquidity crisis.

The inquiry also signals that even as some crypto regulations have been rolled back under the current administration, Democratic lawmakers are preparing for a potential return to power with a more skeptical approach to industry-friendly policies. Blumenthal has not publicly commented on the scope or timeline of his investigation, but his office has reportedly requested documents related to Cantor Fitzgerald's due diligence and compliance procedures for its Tether relationship.
