An $84.2 Million Forfeiture Filing

Federal prosecutors in California are moving to confiscate $84.2 million tied to Capstone Ltd., a Montana-registered payments firm whose accounts were allegedly used to move money on behalf of Tether, the issuer of the dollar-pegged stablecoin USDT. The US Department of Justice filed a civil forfeiture complaint on July 15 in the Eastern District of California, where the case sits before Judge Dale A. Drozd. Prosecutors argue Capstone functioned as an unlicensed money transmitter in at least six states while presenting itself to banks as an information-technology services vendor. The Tether connection runs through EQIBank, a Dominica-based offshore institution: Capstone registered in Montana just three weeks after agreeing in August 2024 to process EQIBank work. The filing also accuses the firm of helping fraud rings that impersonated FBI agents convert elderly victims' cash into crypto. Notably, the Justice Department does not allege misconduct by Tether itself. When federal agents executed a search warrant at a Sacramento residence, Capstone's owners, Kotaro Shimogori and Mary Jane Thompson, were present; the company denies any violation and says it hopes for a quick resolution.

Where the $84.2 Million Actually Sat

Most of the money at issue never touched a blockchain. Court documents show $79.11 million was pulled from a Capstone account at Wells Fargo Securities on September 14, with a further $2.06 million drawn from a JPMorgan Chase account and $1.86 million from a second Wells Fargo Securities account. Only about $1.1 million was spread across two crypto wallets holding USDT. That distribution carries the widest implications: it shows that the plumbing behind the world's largest stablecoin still runs through conventional correspondent banking, not on-chain rails. Civil forfeiture law lets prosecutors seize crime-linked funds regardless of whether the owner is ever charged or convicted, and the target here is the property itself. Prosecutors say Capstone processed a high volume of payments for two crypto-related businesses under instructions from EQIBank. Tether has acknowledged it was an EQIBank customer but says it had no knowledge of the Capstone flows now under scrutiny, which allegedly ran from August 2024 through December 2025. The issuer puts its exposure at the bank at under 0.034% of group assets — a figure that, applied to the $187.75 billion asset base in its second-quarter attestation, works out to roughly $64 million.

EQIBank Warns of Collapse as Tether Distances Itself

The fallout is landing hardest on the bank in the middle. EQIBank has told the court the seizure amounts to $89 million — roughly 80% of its own funds — and warned it could be pushed into liquidation. Capstone's attorneys deny wrongdoing and plan to move for dismissal of the forfeiture claim. Tether, which publishes quarterly reserve attestations, reported about $187.75 billion in assets at the end of June, USDT circulation near $184.6 billion, more than 60% of the stablecoin market and $1.5 billion in quarterly operating profit — against which the frozen EQIBank-linked sums barely register, as we set out in our earlier coverage of the issuer's sub-0.034% exposure at the seizure-hit bank. The episode lands amid a wider enforcement push: on September 14 the Justice Department filed a separate suit seeking roughly $61 million in USDT allegedly tied to Iranian crude sales, and in April Tether said it helped the US government freeze $344 million in USDT linked to sanctions evasion and criminal networks. In each case, enforcement targets the payment rails around the token — from correspondent banks toward Tether's own Stablechain network — rather than the issuer's reserves.

What the Docket Itself Establishes

For all the headlines naming Tether, the load-bearing document is the forfeiture complaint. The docket in the Eastern District of California states a narrow legal claim: that funds moving through Capstone's accounts are traceable to unlicensed transmission and wire fraud — not that the issuer's reserves are impaired. Our read is that reserve transparency and payment-rail transparency are two different things, and this case exposes the second. BIS and IMF research published this year has warned that withdrawal runs or court-blocked dollar channels could transmit stress to emerging markets. With the Fed's draft rules on redemption timelines under discussion and European policymakers still weighing the MiCA reserve rule that kept USDT out, the ruling on Capstone's expected motion to dismiss is the milestone to watch.
