# What happened U.S. prosecutors filed a civil forfeiture complaint that led to the freezing of about $84 million in accounts tied to Capstone, a payments company based in Montana. The Department of Justice says Capstone operated without a license and moved funds on behalf of many individuals and entities.
# Where Tether fits in Capstone to send and receive money. Tether told Cointelegraph it was a customer of EQIBank but that the balances held there amounted to 0.034% of the group's total assets. The company said it had "no knowledge" of the conduct alleged in the complaint.
Tether and Bitfinex were both named in reporting tied to the seizure. The complaint alleges Capstone handled hundreds of millions of dollars at the direction of EQIBank, and that some movements of funds involved accounts linked to those firms.
# Immediate implications The seizure targets Capstone accounts specifically. Tether framed its position as limited exposure through a banking relationship, not direct involvement in the alleged payments activity. Tether did not answer a question about whether the seizure could affect its customers.
At the time of the report USDT had a market capitalization near $184 billion, which positions the frozen amounts as small relative to the stablecoin's overall market size.
# Why this matters to industry participants Banking relationships matter for stablecoin issuers and exchanges because funds move between fiat rails and crypto platforms. A U.S. forfeiture action that ties a payment processor and an offshore bank to alleged unlicensed activity raises questions about counterparty due diligence, reserve custody, and the legal exposure of intermediary firms.
That said, Tether's reporting of exposure at 0.034% of group assets signals the company views the risk as limited in scale. The DOJ complaint focuses on alleged unlawful payments conducted by Capstone rather than on Tether's reserves or broader operations.
# Questions still open
# Takeaway The DOJ action froze a sizable sum at a payment firm tied to EQIBank. Tether says the bank relationship involved a negligible portion of its assets and denies awareness of the alleged activity. For market participants, the episode is a reminder that third-party banking and payment partners can create legal and operational risk even when direct exposure appears small.
