U.S. DOJ Seizes Over $84 Million in Accounts Linked to Tether-Associated Payment Processor
nashnova research
U.S. federal prosecutors froze roughly $84 million in bank accounts belonging to Montana payment company Capstone, alleging it secretly moved funds for stablecoin giant Tether — exposing, once again, Tether's struggle to access mainstream banking.
How did the $84 million get frozen?
The U.S. Attorney for the Eastern District of California filed a civil forfeiture complaint in July, freezing Capstone's accounts at Wells Fargo and JPMorgan Chase.
The core allegation: Capstone had no money-transmission license, yet moved over $700 million through its Wells Fargo account — with net outflows of roughly $337 million after excluding Treasury purchases.
This means → prosecutors are describing not a minor compliance slip but a large-scale crypto-funding pipeline hidden inside the traditional banking system.
How did Capstone fool major banks?
Capstone was registered in Montana — the only U.S. state that does not require a money-transmitter license.
When opening accounts, it described itself as an "IT services company," securing accounts at Citi, JPMorgan, and Wells Fargo and dodging their anti-money-laundering risk flags.
In May 2025, Citi shut the account after spotting AML red flags. Capstone promptly moved $65 million to Wells Fargo and kept going.
In plain terms = a shell company changed its industry label and walked past the compliance gates of three top-tier U.S. banks.
What exactly links Capstone to Tether?
The bridge is EQI Bank, a small bank in Dominica in the Caribbean. Capstone signed on with EQI in August 2024 to process dollar flows for Tether and its sister exchange Bitfinex.
A deeper tie: Tether's investment adviser Marlin Capital bought a $10 million convertible note in EQI Bank in 2024. One negotiation condition: EQI would help Tether open at least one account at Singapore's DBS Bank.
This reflects how desperately Tether needs legitimate banking access — willing to invest in a tiny offshore bank in exchange for an account opening.
Beyond Tether's money, what else did Capstone do?
Prosecutors allege Capstone also helped scammers posing as FBI agents convert cash stolen from elderly victims into stablecoins.
This means → Capstone was not merely a grey-area conduit; the charges place it inside an active criminal fraud chain.
What are the parties saying?
Tether and Bitfinex: confirmed they are EQI Bank clients but said they had "no knowledge" of Capstone's alleged fraud and hold "limited" assets at EQI.
EQI Bank: filed a motion in June claiming "innocent owner" status, saying Capstone misled it into believing the firm was "duly registered."
Capstone's attorney: "denies any wrongdoing," plans to file a motion to dismiss; the FBI has executed a search warrant at the home of its operator.
What does this mean for Tether?
Tether holds over $140 billion in U.S. Treasuries and has moved its registration to El Salvador, yet it still relies on small offshore banks to maintain its dollar pipeline.
In plain terms = the world's largest stablecoin issuer, with assets rivaling a mid-sized sovereign fund, still cannot secure a stable U.S. bank account.
This reflects the core contradiction of the stablecoin industry: the product is pegged to the dollar, but the issuer is locked out of the dollar banking system — whether that structural problem gets resolved as regulation takes shape remains the market's biggest open question.
