U.S. Department of Justice Moves to Seize $84.2 Million Tied to Tether Payment Processor Capstone Ltd.

WASHINGTON/SACRAMENTO — In a major escalation of federal scrutiny targeting the financial pipelines connecting traditional banking systems to the digital asset economy, the United States Department of Justice (DOJ) is seeking to permanently seize $84.2 million in funds tied to Capstone Ltd., a Montana-registered payment processing firm.

According to a civil forfeiture complaint filed in the U.S. District Court for the Eastern District of California before Judge Dale A. Drozd, the targeted capital flowed through accounts used to facilitate transactions for Tether, the issuer of the world’s largest stablecoin, USDT. Federal prosecutors allege that Capstone operated as an unlicensed money-transmitting business across at least six U.S. states while actively masking its operations from traditional financial institutions by posing as a standard information technology (IT) services provider.

The unfolding legal battle exposes the complex, often opaque web of intermediary shadow-banking networks, offshore financial institutions, and digital asset liquidity providers that operate at the fringes of mainstream global finance. With a Dominica-licensed digital bank warning of imminent liquidation and major traditional financial institutions caught in the crossfire, the case highlights the intensifying regulatory crackdown on compliance gaps within the cryptocurrency sector.


Main Facts of the Case

At the core of the DOJ’s civil forfeiture complaint is the allegation that Capstone Ltd. functioned as an illegal money transmitter. Under federal law, businesses that accept and transmit currency or funds from one person or location to another are subject to rigorous regulatory registration, anti-money laundering (AML) controls, and Know Your Customer (KYC) mandates.

Prosecutors claim that Capstone systematically bypassed these requirements. Rather than registering as a money services business (MSB) with the Financial Crimes Enforcement Network (FinCEN) and complying with state-level licensing laws, the firm allegedly represented itself to major U.S. commercial banks as an ordinary IT services company. This misrepresentation allegedly allowed Capstone to open and maintain corporate banking accounts that moved massive sums of capital on behalf of third parties without triggering the standard compliance reviews mandated for high-volume payment processors.

The civil forfeiture mechanism deployed by the DOJ does not require a prior criminal conviction of the funds’ owners. Instead, civil forfeiture allows the government to target property that it asserts was derived from, or used to facilitate, unlawful activity.

The $84.2 million targeted by federal prosecutors is scattered across multiple major traditional banking institutions and digital asset platforms:

  • $79.11 million was seized from a single Wells Fargo Securities account held in Capstone’s name on September 14.
  • $2.06 million was held in accounts at JPMorgan Chase.
  • $1.86 million was located in a separate Wells Fargo account.
  • Just over $1.1 million was split across two digital asset wallets holding USDT, the dollar-pegged stablecoin issued by Tether.

Federal law enforcement agencies have already initiated physical and digital enforcement actions. The Federal Bureau of Investigation (FBI) executed a search warrant at a residential property in Sacramento, California, linked to Capstone’s owners, Kotaro Shimogori and Mary Jeanne Thompson. Both individuals are explicitly named in the government’s complaint as central figures in the operation of the firm.


Chronology of Events and Legal Escalation

While the civil forfeiture complaint was formally filed on July 15, the operational framework and financial movements underpinning the case stretch back over several years, culminating in recent dramatic seizures by federal authorities.

  • Pre-2024 (Operations & Fronting): According to federal investigators, Capstone Ltd. establishes itself in Montana as an IT services provider. Over the subsequent years, the firm opens accounts with major U.S. financial institutions—including Wells Fargo and JPMorgan Chase—while secretly operating as an unlicensed money transmitter moving tens of millions of dollars.
  • The Intermediary Link: EQIBank, a digital bank licensed in the Commonwealth of Dominica, allegedly assumes a directorial role over Capstone, instructing the Montana-based processor on how to route payments and manage liquidity for high-volume cryptocurrency transactions, specifically concerning USDT processing.
  • July 15: The U.S. Department of Justice files a civil forfeiture complaint in the U.S. District Court for the Eastern District of California (Case: U.S. v. $84.2M Belonging to Capstone Ltd.) before Judge Dale A. Drozd.
  • September 14: Federal authorities execute the seizure of $79.11 million from a Wells Fargo Securities account bearing Capstone’s name. Additional accounts at JPMorgan Chase and secondary Wells Fargo holdings are similarly targeted, bringing total seized fiat and digital assets to $84.2 million.
  • FBI Raids: The FBI executes a search warrant at a Sacramento residence associated with Capstone principals Kotaro Shimogori and Mary Jeanne Thompson.
  • Late September: Public disclosures reveal the profound collateral impact of the seizures. EQIBank issues court-filed warnings indicating that the loss of the funds—representing approximately 80% of the bank’s total holdings—could force the institution into liquidation. Tether issues public statements distancing itself from Capstone’s alleged conduct while confirming the bank’s historical role in processing USDT transfers.

Supporting Data and Financial Exposure

The financial dimensions of the Capstone forfeiture extend far beyond the immediate $84.2 million seizure, rippling through regional offshore banking and casting a spotlight on the capital reserves of the wider stablecoin industry.

EQIBank’s Liquidation Risk

Perhaps the most vulnerable institution in the wake of the DOJ’s action is EQIBank. Licensed in Dominica, the digital bank served as a foundational partner in directing Capstone’s payment movements. Court filings indicate that the seized assets account for roughly 80% of EQIBank’s entire balance sheet. Legal representatives for the bank have warned the court that the permanent forfeiture of these funds would effectively drain its liquidity reserves, making insolvency and subsequent liquidation nearly inevitable.

Tether’s Exposure Assessment

Tether Holdings Limited, the issuer of USDT, has moved quickly to contain the public relations and systemic fallout of the enforcement action. In statements provided to major financial news outlets including Reuters and The Information, Tether confirmed that EQIBank had previously been utilized to handle certain USDT purchase and redemption transfers.

However, Tether emphatically distanced itself from the alleged misconduct of the payment processor:

"Tether has no knowledge of the conduct by Capstone alleged by the Department of Justice," a company spokesperson stated.

To contextualize the financial impact, Tether disclosed that the total exposure tied to the incident amounts to less than 0.034% of the company’s total group assets. When weighed against Tether’s second-quarter financial disclosures—which reported a massive $187.75 billion in total reserves and assets, alongside a $1.5 billion profit in Q2—the direct financial blow to the stablecoin issuer is negligible. Nevertheless, the indirect reputational and banking-access implications remain a point of concern for market watchers.


Official Responses and Legal Defense

Legal counsel representing Cap性和 EQIBank have mobilized to contest the government’s seizure under established U.S. civil forfeiture rules.

The Defense Position

Attorneys for Capstone Ltd. have maintained a posture of absolute denial regarding the federal allegations. Speaking to the Financial Times, a legal representative for the firm stated that Capstone "denies any wrongdoing" and expressed intentions to "resolve this matter quickly."

Furthermore, both Capstone and EQIBank have formally filed an "innocent-owner defense" in the Eastern District of California. Under Supplemental Rule G of the Supplemental Rules for Admiralty or Maritime Claims and Asset Forfeiture Actions—which governs federal civil forfeiture proceedings—claimants possess a strict 21-day window to formally answer the government’s complaint after submitting a verified claim. The defense teams are expected to argue that the funds were gathered and processed through legitimate business channels and that the institutions lacked knowledge of any alleged regulatory evasion or unlicensed money transmission.

Historical Context: Tether and Regulatory Scrutiny

The Capstone forfeiture arrives against a backdrop of historic regulatory tension between U.S. authorities and the leadership of Tether and its sister company, crypto exchange Bitfinex.

The most prominent precedent occurred in February 2021, when Tether and Bitfinex reached a landmark settlement with the New York Attorney General (NYAG) following a sweeping investigation into their reserve backing and banking relationships. As part of that settlement:

  • The companies admitted that USDT was not always backed dollar-for-dollar by traditional fiat currency reserves during specific periods, as they had previously claimed.
  • They agreed to pay an $18.5 million fine.
  • Both entities agreed to completely cease trading and operational activities involving New York residents and state-registered entities.
  • They committed to providing regular, detailed transparency reports regarding the composition of their commercial paper, Treasury bills, and cash equivalent reserves.

While the 2021 settlement focused primarily on reserve transparency and jurisdictional compliance, the current DOJ action against Capstone signals a tactical shift toward dismantling the clandestine payment rails and shadow-processing networks that allow offshore crypto entities to interface with domestic U.S. commercial banks.


Broader Implications for the Crypto and Banking Sectors

The DOJ’s aggressive targeting of Capstone Ltd. carries profound implications for the broader cryptocurrency ecosystem, traditional banking partners, and compliance frameworks globally.

1. The Crackdown on "Shadow" Payment Processors

The case serves as a stark warning to third-party payment processors operating within the digital asset economy. For years, crypto firms—facing systematic "de-banking" by risk-averse traditional financial institutions—have relied on intermediary fintech firms, boutique payment gateways, and offshore entities to bridge the gap between fiat banking rails (ACH, wire transfers) and crypto liquidity.

By prosecuting firms that present themselves as IT providers while secretly executing high-volume money transmissions, the DOJ is signaling that the corporate veil of intermediary processors will be aggressively pierced. Payment processors can no longer rely on obfuscation or misleading business classifications to bypass MSB registration and licensing laws.

2. The Vulnerability of Offshore Banking Partners

The plight of EQIBank underscores the systemic risk faced by smaller, offshore digital banks that cater to high-risk cryptocurrency clients. When U.S. federal authorities freeze or seize multi-million-dollar accounts held at domestic correspondent banks (such as Wells Fargo and JPMorgan Chase), the shockwaves instantly destabilize the offshore institutions that rely on those U.S. accounts for cross-border settlement. For smaller banks, a single federal forfeiture action can spell total collapse, creating a chilling effect across international banking jurisdictions like Dominica, the Bahamas, and the Cayman Islands.

3. Stablecoin Issuers and Counterparty Risk

While Tether’s vast reserve pool ($187.75+ billion) insulates it from direct insolvency risks stemming from the Capstone seizure, the case highlights the persistent vulnerability of stablecoin issuers to third-party counterparty risk. Even if Tether maintains immaculate internal reserves, its business model fundamentally relies on an external network of banking partners, authorized participants, liquidity providers, and payment processors to distribute and redeem USDT. If U.S. law enforcement continues to systematically dismantle these peripheral payment pipelines, maintaining frictionless global liquidity for stablecoins will become increasingly difficult.

4. Heightened Compliance and Due Diligence

In the wake of this enforcement action, major commercial banks are expected to drastically ramp up their surveillance of corporate accounts suspected of engaging in digital asset activities. Compliance officers will face heightened pressure to audit firms claiming to be generic "IT services providers" or software consultants to ensure they are not acting as unlicensed conduits for cryptocurrency transactions. For the digital asset industry, the message from Washington is unequivocal: the era of gray-market payment processing is rapidly closing, and full regulatory compliance is no longer optional.


As the legal proceedings in the U.S. District Court for the Eastern District of California continue under Judge Dale A. Drozd, all parties have until the conclusion of their respective procedural deadlines to present further evidence supporting or contesting the forfeiture of the $84.2 million.
