Democratic Senators Elizabeth Warren and Richard Blumenthal issued a letter to Meta CEO Mark Zuckerberg, raising concerns over reports that the tech giant is once again exploring the launch of its own stablecoin.

In the letter, the senators warn that Metas renewed interest in digital currency, reminiscent of its failed Libra and Diem initiatives, could pose serious risks to financial privacy, economic competition, and national monetary sovereignty.

Zuckerberg Pressed on Stablecoin Strategy

Citing recent reports that Meta has been in discussions with crypto firms and hired a fintech executive to lead its stablecoin push, the lawmakers argued that any such move, whether through direct issuance or strategic partnership, would allow the company to tighten its grip over payments across its massive 3.5-billion-user ecosystem.

The senators express concern that a Meta-backed stablecoin could allow deeper surveillance of user transactions, threaten competition, and expose consumers to systemic financial instability. Drawing parallels with the 2023 depegging of USDC and the subsequent federal backstop, they warn that taxpayers may again be forced to shoulder the consequences of a run on a Meta-linked stablecoin.

Beyond financial risk, the letter also outlined the companys history of privacy violations, antitrust investigations, and failure to safeguard users, especially children, from harm, and argued that such a record makes the company uniquely unfit to manage a private currency system.

The timing of the companys revived stablecoin ambition is also significant, coming as Congress debates the GENIUS Act, which could pave the way for Big Tech to issue digital dollars through lightly regulated affiliates. Warren and Blumenthal question whether Meta is lobbying lawmakers to influence the bills language and seek clarification on whether the company is trying to exploit regulatory loopholes to gain a controlling stake in a stablecoin issuer.

Meta Faces June 17 Deadline

The letter also demands detailed disclosures by June 17, including a list of consulted crypto firms, intended platforms for deployment, and lobbying activity related to the GENIUS and STABLE Acts. The senators have called on the tech company to explain how its current stablecoin plans differ from the Libra and Diem projects and what steps have been taken to address past concerns.

In a clear pushback against what they see as a dangerous overreach, the lawmakers ask whether it would support amendments to block Big Tech firms from issuing or controlling stablecoins explicitly.
