The United States Department of Justice has launched a high-stakes civil forfeiture action aiming to seize $84.2 million in funds tied to institutional payment processing for Tether, the world’s largest stablecoin issuer. Filed in the U.S. District Court for the Eastern District of California under Judge Dale A. Drozd, the legal action targets Capstone Ltd., a Montana-registered payment processing firm accused of operating as an unlicensed money services business. The case underscores intensifying regulatory scrutiny over the intricate web of traditional banking entities, shadow financial intermediaries, and digital asset issuers that facilitate multi-billion-dollar cryptocurrency flows globally.
According to court filings, the vast majority of the targeted capital—specifically $79.11 million—was pulled directly from a Wells Fargo Securities account held in Capstone’s name on September 14. An additional $2.06 million was housed at JPMorgan Chase, $1.86 million sat in a secondary Wells Fargo account, and roughly $1.1 million was distributed across two digital wallets containing USDT, the dollar-pegged stablecoin managed by Tether. The sweeping legal move has reverberated across the traditional and digital financial sectors, placing offshore banking partners on high alert and prompting swift defenses from the corporate entities involved.
The Allegations Against Capstone Ltd. and Its Principals
At the center of the Justice Department’s civil forfeiture complaint are Capstone Ltd. and its primary operators, Kotaro Shimogori and Mary Jeanne Thompson. Federal investigators allege that Capstone functioned as an unlicensed money transmitting business across at least six U.S. states. Under federal and state financial laws, entities that receive and transmit third-party funds are required to secure explicit licenses, register with the Financial Crimes Enforcement Network (FinCEN), and implement rigorous Anti-Money Laundering (AML) and Know Your Customer (KYC) compliance programs.
Prosecutors claim that Capstone systematically bypassed these statutory obligations by misrepresenting its core business model to traditional financial institutions. Rather than disclosing its true function as a high-volume payment processor moving millions of dollars on behalf of offshore crypto-related clients, Capstone allegedly presented itself to major U.S. banks as an ordinary information technology services company. This alleged deception allowed the firm to establish and maintain corporate banking accounts that funneled substantial sums of capital through the domestic financial system without attracting immediate compliance flags.
The FBI’s involvement crystallized when federal agents executed a search warrant at a residential property in Sacramento linked to the firm’s operations. Despite the gravity of the allegations, legal representation for Capstone has pushed back against the government’s characterization of its business activities. In statements provided to the financial press, an attorney representing the firm asserted that Capstone "denies any wrongdoing" and expressed an intent to vigorously contest the forfeiture to "resolve this matter quickly."
The Offshore Nexus: EQIBank and the Threat of Liquidation
The civil forfeiture complaint does not stop at Capstone; it also illuminates the critical role played by offshore financial institutions in routing digital asset liquidity. Prosecutors have identified EQIBank, a digital bank licensed in the Commonwealth of Dominica, as the institutional mastermind that directed how Capstone moved and organized the processed funds.
EQIBank’s exposure to the Department of Justice’s seizure action is existential. Legal filings and institutional disclosures indicate that the seized $84.2 million accounts for roughly 80% of all capital held by the bank. Representatives for EQIBank have warned the presiding court that the permanent loss of these funds would deal a catastrophic blow to the institution’s balance sheet, effectively rendering it insolvent and forcing the bank into formal liquidation.
In response to the legal maneuver, both Capstone and EQIBank have mobilized a coordinated defense, filing an "innocent-owner" claim under Supplemental Rule G of the Federal Rules of Civil Procedure. This procedural mechanism grants claimants a strict 21-day window following formal notice to challenge government seizures by demonstrating that they lacked knowledge of any illicit conduct or that the assets were not derived from unlawful activities.
Tether’s Official Response and Risk Exposure
As the legal battle unfolds, Tether Holdings Limited has moved quickly to distance its primary corporate operations from the legal woes of its intermediaries, while clarifying its institutional exposure. In statements issued to major news organizations, a Tether spokesperson confirmed that EQIBank had indeed been utilized to handle certain USDT purchase and redemption transfer operations. However, the company categorically denied any institutional awareness of the specific regulatory violations alleged against Capstone by U.S. prosecutors.

"Tether has no knowledge of the conduct by Capstone alleged by the Department of Justice," a company spokesperson stated, emphasizing that the digital asset issuer operates with strict compliance protocols and relies on third-party banking networks that are independently responsible for adhering to local and international financial regulations.
From a financial standpoint, Tether sought to reassure markets that the enforcement action represents a negligible fraction of its overarching financial reserves. According to the company, the frozen funds and associated exposure amount to less than 0.034% of the group’s total assets. This figure must be viewed through the lens of Tether’s broader financial standing; at the close of the second quarter, the company reported a massive $187.75 billion in total reserves backing its circulating USDT supply, alongside a robust $1.5 billion profit for the quarter.
A History of Regulatory Scrutiny
This civil forfeiture action is not an isolated incident in the regulatory history of Tether and its sister company, Bitfinex. Over the past several years, the issuers of the world’s most dominant stablecoin have repeatedly found themselves in the crosshairs of federal and state regulatory agencies concerning their banking arrangements and reserve transparency.
The most notable historical precedent occurred in 2021, when Tether and Bitfinex reached a comprehensive settlement with the New York Attorney General’s office. That investigation revealed that the companies had previously masked the loss of hundreds of millions of dollars in corporate funds by shuffling money between Tether reserves and Bitfinex operational accounts, contradicting prior public claims that USDT was perpetually backed on a one-to-one basis by traditional fiat currency. Without admitting or denying the findings, Tether and Bitfinex agreed to pay an $18.5 million civil penalty, submit to regular periodic reporting requirements regarding their reserve compositions, and halt direct trading operations for New York residents.
Subsequent years have seen ongoing inquiries by the Commodity Futures Trading Commission (CFTC) and the Department of Justice into various facets of stablecoin issuance, commercial paper holdings, and international banking conduits. While Tether has successfully adapted its reserve portfolio—substituting high-risk commercial paper with ultra-safe U.S. Treasury bills—the latest seizure action demonstrates that federal regulators are increasingly targeting the plumbing of the cryptocurrency ecosystem: the payment processors and boutique digital banks that bridge the gap between traditional fiat rails and decentralized networks.
Implications for the Cryptocurrency and Banking Sectors
The civil forfeiture action against Capstone’s accounts serves as a watershed moment for the intersection of traditional banking compliance and digital asset liquidity. By utilizing civil forfeiture—a legal tool that permits the government to seize assets suspected of involvement in criminal activity without requiring a prior criminal conviction against the asset’s owner—the Department of Justice can disrupt illicit capital flows with unprecedented speed.
The broader implications of this case are multifaceted:
-
Increased Scrutiny on Payment Intermediaries: Crypto-friendly payment processors operating in the United States and abroad face heightened pressure to ensure absolute transparency with their banking partners. The alleged practice of masquerading as IT service providers to secure bank accounts is likely to trigger industry-wide audits by major commercial banks seeking to purge high-risk fintech clients from their balance sheets.
-
The Vulnerability of Offshore Banking Bridges: The precarious position of EQIBank highlights the systemic risks inherent in relying on smaller, offshore digital banks to manage institutional-grade crypto liquidity. If offshore institutions can be crippled by domestic U.S. asset seizures, digital asset issuers may find it increasingly difficult to secure reliable fiat-to-crypto gateway partners.
-
Stablecoin Dominance Amid Regulatory Headwinds: Despite the recurring legal friction surrounding its banking partners, Tether’s market dominance has proven remarkably resilient. While institutional exposure to enforcement actions creates short-term volatility and compliance friction, the immense demand for USDT as a trading pair across global cryptocurrency exchanges ensures that the token remains a foundational pillar of the digital economy.
As the legal proceedings in the Eastern District of California progress under Judge Drozd, the defense mounted by Capstone and EQIBank will test the boundaries of the innocent-owner defense in cryptocurrency-related asset seizures. Meanwhile, federal regulators continue to send an unmistakable message: the traditional financial system will no longer tolerate opaque, unlicensed intermediaries acting as quiet conduits for the multi-billion-dollar stablecoin economy.
