US Department of Justice Seizes $84.2 Million in Civil Forfeiture Targeting Montana Payments Firm Capstone Ltd. and Tether-Linked Accounts

The United States Department of Justice has launched an aggressive legal effort to seize $84.2 million in funds tied to an intricate, multi-jurisdictional payment processing network utilized by the stablecoin issuer Tether. According to a civil forfeiture complaint filed in the U.S. District Court for the Eastern District of California, the federal government is targeting capital routed through accounts operated by Capstone Ltd., a Montana-registered payments processor. The legal action, presided over by Judge Dale A. Drozd, highlights the intensifying regulatory scrutiny facing the operational and banking lifelines that support the multi-billion-dollar cryptocurrency ecosystem.

The core of the government’s case centers on allegations that Capstone functioned as an unlicensed money-transmitting business across at least six U.S. states. Federal regulators maintain that Capstone deliberately disguised its true commercial activities from major traditional financial institutions, presenting itself to corporate banks as a benign information technology services firm while secretly executing millions of dollars in financial transactions on behalf of third parties. The civil forfeiture complaint pulls back the curtain on a web of corporate entities, offshore banking partners, and digital asset wallets that prosecutors claim were designed to obscure the origins and destinations of vast sums of fiat currency.

The Mechanics of the Alleged Scheme

Under United States federal law, entities that accept and transmit currency, funds, or other value that substitutes for currency from one person or location to another are strictly classified as money services businesses (MSBs). Such entities are legally obligated to register with the Financial Crimes Enforcement Network (FinCEN), implement robust Anti-Money Laundering (AML) and Know Your Customer (KYC) compliance programs, and maintain transparent relationships with their partner banks.

According to the Department of Justice’s filing, Capstone bypassed these federal and state licensing mandates entirely. Prosecutors assert that the firm’s leadership—identified in court documents as Kotaro Shimogori and Mary Jeanne Thompson—orchestrated a systematic deception of traditional banking partners. By cloaking Capstone as an ordinary IT services provider, the firm allegedly secured access to institutional banking infrastructure without triggering the rigorous compliance oversight typically required for entities handling high-volume payment processing.

The financial footprint of this operation was substantial. The forfeiture complaint details how tens of millions of dollars flowed through corporate accounts held at premier American financial institutions. Of the $84.2 million targeted by federal prosecutors, the vast majority—specifically $79.11 million—was abruptly extracted from a Wells Fargo Securities account held in Capstone’s name on September 14. Additional segments of the seized capital included $2.06 million held at JPMorgan Chase, $1.86 million residing in a separate Wells Fargo account, and roughly $1.1 million distributed across two digital wallets containing USDT, the flagship stablecoin issued by Tether.

Civil forfeiture is a distinct legal instrument in the American jurisprudence system that allows the government to seize property suspected of being involved in criminal activity without necessarily securing a criminal conviction against the property’s owner. In these proceedings, the legal action is brought directly against the asset itself—hence formal case titles such as United States v. $84.2m Belonging to Capstone Ltd.—placing the burden of proof on the claimants to establish the legitimate and lawful origin of the disputed funds.

EQIBank and the Offshore Nexus

The structural complexity of the Capstone network extends far beyond domestic U.S. banks. Behind the Montana-registered payment processor sits EQIBank, a digital bank licensed in the Caribbean island nation of Dominica. According to federal prosecutors, EQIBank actively directed and coordinated how Capstone moved money through the international financial system, acting as a vital conduit between traditional fiat accounts and the broader digital asset economy.

The fallout for EQIBank threatens to be catastrophic. Legal filings and institutional disclosures indicate that the loss of the $84.2 million represents approximately 80 percent of the bank’s total asset reserves. Representatives for EQIBank have warned the court that the permanent forfeiture of these funds would likely push the institution into irreversible liquidation, dealing a severe blow to its international clientele and specialized digital banking operations.

The involvement of EQIBank directly intersects with the operational architecture of Tether, the world’s largest stablecoin issuer by market capitalization. Court documents and corporate confirmations reveal that EQIBank was utilized to handle specific USDT purchase and redemption transfers—the fundamental mechanism by which institutional traders and arbitrageurs exchange fiat currency for digital tokens, and vice versa.

Tether’s Response and Risk Exposure

As news of the sweeping asset seizure reverberated through global financial markets, Tether moved quickly to distance its corporate operations from the unfolding legal drama. In an official statement provided to Reuters, Tether acknowledged that EQIBank had indeed acted as a banking partner facilitating USDT purchase and redemption transfers. However, the company categorically denied any direct involvement in or awareness of the illicit conduct alleged against Capstone by the Department of Justice.

Tether representatives moved to reassure investors and market participants by contextualizing the financial exposure relative to the firm’s massive balance sheet. According to public statements, the total potential exposure tied to the seized accounts accounts for less than 0.034 percent of the company’s total group assets. This minuscule proportion stands in stark contrast to Tether’s robust financial standing; at the close of the second quarter, the company reported a staggering $187.75 billion in total reserves and assets, reinforced by strong profitability driven by high-yield U.S. Treasury holdings and rising adoption of USDT across global digital asset markets.

Despite these assurances, the incident underscores the persistent structural vulnerabilities that crypto issuers face regarding their reliance on third-party payment processors and offshore banking intermediaries. While Tether maintains strict internal compliance and redemption protocols, the reliance on specialized conduits to bridge the gap between traditional banking networks and public blockchains frequently introduces systemic third-party risks that escape direct corporate oversight.

A History of Regulatory and Legal Scrutiny

The current civil forfeiture action is far from the first time Tether and its sister company, Bitfinex, have found themselves in the crosshairs of American or international regulators concerning their monetary movements and banking relationships. The crypto industry has long watched the stablecoin issuer closely, given its pivotal role as the primary liquidity provider and trading pair foundation for the global digital asset economy.

The most notable precedent occurred in 2021, when Tether and Bitfinex reached a comprehensive settlement with the New York Attorney General’s Office. That multi-year investigation culminated in findings that the companies had misrepresented the nature and backing of their stablecoin reserves during periods of intense market stress, specifically acknowledging that USDT was not always backed strictly on a one-to-one basis by cash equivalents at all times. To resolve the investigation, Tether and Bitfinex agreed to pay an $18.5 million civil penalty, submit to rigorous periodic reporting requirements regarding their reserve compositions, and formally cease all trading and business operations within the state of New York.

Subsequent years have seen Tether make significant strides toward regulatory transparency, routinely publishing independent attestation reports prepared by major accounting firms to verify the composition of its multi-billion-dollar reserve portfolio. Nevertheless, prosecutors and financial watchdogs continue to focus heavily on the secondary plumbing of the industry—the obscure web of over-the-counter (OTC) desks, payment processors, and boutique digital banks that facilitate the movement of fiat capital into and out of digital asset ecosystems.

Legal Defense and Next Steps

In the wake of the Department of Justice’s forfeiture filing, legal representatives for the targeted entities are mounting a vigorous defense. Attorneys for Capstone and its owners, Kotaro Shimogori and Mary Jeanne Thompson, have firmly asserted their clients’ innocence. Speaking to the Financial Times, legal counsel stated that the company "denies any wrongdoing" and expressed a commitment to resolving the matter swiftly through the appropriate legal channels.

Concurrently, Capstone and EQIBank have formally filed innocent-owner defenses under Supplemental Rule G, the procedural framework governing federal civil forfeiture actions in admiralty and maritime claims as well as asset forfeiture proceedings. Under this rule, once the government files a verified complaint and formal notice is served, claimants are granted a strict window of 21 days to file a formal claim asserting their ownership interest, followed by an additional 20 days to file a detailed answer contesting the government’s allegations.

If the claimants fail to substantiate a legitimate, lawful source of funds or successfully demonstrate that they were innocent participants without knowledge of any underlying illicit activities, the federal government will move to permanently forfeit the $84.2 million to the United States Treasury.

Broader Implications for the Digital Asset Ecosystem

The ongoing legal battle over Capstone’s accounts serves as a critical bellwether for the evolving relationship between traditional financial regulation and the cryptocurrency sector. As global regulators—particularly in the United States—increase their focus on enforcement actions targeting unlicensed money transmission, banking partners operating in offshore jurisdictions face unprecedented operational risks.

For stablecoin issuers like Tether, the case highlights the urgent necessity of conducting rigorous, continuous compliance audits of every node within their payment processing and redemption chains. While major issuers command enormous financial resources and balance sheet stability, the actions of peripheral intermediaries can instantly trigger systemic ripples, freezing critical capital reserves and attracting intense regulatory scrutiny.

As Judge Dale A. Drozd oversees the proceedings in the Eastern District of California, the legal community and digital asset markets alike will be watching closely. The outcome of United States v. $84.2m Belonging to Capstone Ltd. will not only determine the ultimate fate of millions of dollars in disputed funds and potentially decide the survival of EQIBank, but it will also establish vital legal precedents regarding the enforcement of U.S. money transmission laws over international payment networks bridging the traditional and digital financial worlds.
