US Prosecutors Seek $84.2M From Bank Tied to Tether and Bitfinex
US federal prosecutors have filed a civil forfeiture action targeting $84.2 million held at a bank with established ties to Tether and Bitfinex. The action is one of the largest stablecoin-adjacent enforcement moves yet taken by US authorities and sends an unambiguous message to every accounting firm, auditor, and CFO that holds, processes, or reports on USDT balances: counterparty risk in the stablecoin ecosystem is no longer theoretical. It is now a line item in a federal complaint.
What the Forfeiture Action Actually Says
Civil forfeiture allows the US government to seize assets alleged to be proceeds of, or instrumentalities used in, specified unlawful activity, without first securing a criminal conviction. The $84.2 million figure represents funds that prosecutors allege moved through the targeted bank in a manner inconsistent with legitimate banking activity and consistent with patterns associated with money laundering or sanctions evasion.
Why a bank, not Tether or Bitfinex directly
The action is directed at the bank rather than at Tether or Bitfinex as entities. That structure matters for how firms should read this. When prosecutors go after a banking institution that served as a financial gateway for a major stablecoin issuer and its affiliated exchange, they are signaling that correspondent and custodial banking relationships themselves carry compliance exposure. The bank's role, accepting and transmitting funds on behalf of clients connected to a large stablecoin operation, is precisely what brought it into prosecutors' crosshairs.
This approach mirrors enforcement strategies used in earlier crypto-adjacent banking cases, where the institution facilitating the flows faced liability even when it was not the originating actor in any alleged scheme. For accounting professionals, the lesson is that the risk does not sit only with the issuer or the exchange. It travels along the banking rail.
The $84.2 million figure in context
The sum sought is not a fine or a penalty calculated by regulators. It is the government's estimate of the specific funds it claims are subject to forfeiture. That means prosecutors believe they can trace this particular pool of money to conduct that violated US law. Tracing is a forensic accounting exercise, and the fact that the government has put a precise number on the table suggests it has already done substantial blockchain and traditional financial record analysis to support that figure.
Tether and Bitfinex: The Institutional Context
Tether is the issuer of USDT, the world's largest stablecoin by market capitalisation and daily transaction volume. Bitfinex is a cryptocurrency exchange that shares common ownership with Tether. Both have previously settled with US authorities, including a 2021 agreement with the Commodity Futures Trading Commission in which Tether paid $41 million over claims that it had misrepresented its reserve backing. That history is relevant because it means any new enforcement action touching entities in their orbit lands on ground that is already well-ploughed by regulators.
What this means for USDT reserve transparency
One of the persistent accounting questions around Tether has been the composition and verifiability of its reserves. When a bank connected to the issuer becomes the subject of a federal forfeiture action, it raises fresh questions about the integrity of the flows that supported those reserves at a particular point in time. Auditors reviewing clients' USDT holdings will want to consider whether any portion of those holdings was settled through an institution that is now under US government scrutiny, because that fact could affect the supportability of valuations recorded in the financial statements.
AML and Compliance Implications for Accounting Firms
For any firm that acts as a virtual asset service provider, maintains client accounts denominated in USDT, or provides audit or attestation services over financial statements that include stablecoin balances, this action has direct operational consequences.
Counterparty due diligence
The Bank Secrecy Act and FinCEN guidance require financial institutions and, increasingly, crypto-adjacent service providers to conduct ongoing due diligence on the entities through which their clients' funds flow. When a correspondent bank is named in a federal forfeiture action, its designation as a high-risk counterparty becomes difficult to avoid. Firms should review their client onboarding and transaction monitoring frameworks to assess whether any client activity routed funds through this institution.
Transaction monitoring and suspicious activity reporting
If a firm's monitoring systems identify historical transactions involving the named bank, the firm's compliance officer should assess whether those transactions met the threshold for a Suspicious Activity Report at the time. Even if prior filings were made, a material enforcement development like this one may warrant a follow-up review of the underlying facts and, if appropriate, supplemental reporting.
Stablecoin balance sheet positions
Under ASC 350-60, the FASB's fair value framework for crypto assets, stablecoins held by entities subject to US GAAP are marked to fair value at each reporting date. USDT is typically recorded near parity with the US dollar, but enforcement actions affecting the issuer's banking infrastructure can create short-term peg stress that requires firms to reassess the fair value hierarchy classification and disclosure adequacy for any period in which the news was public and the price deviated materially from par. Firms acting as auditors should document their fair value assessment process for any USDT balances on clients' books.
Tax Reporting Dimensions
The enforcement action also has tax implications that CFOs and their advisers should consider, particularly where stablecoin flows were used in commercial transactions.
Forfeiture and ordinary income treatment
If a US taxpayer's assets are ultimately seized under a forfeiture order, the tax treatment depends on whether those assets were held as capital assets or as part of a trade or business. Forfeited amounts generally do not generate a deductible loss to the party whose funds are seized if the forfeiture relates to illegal activity, under longstanding IRS authority. For counterparties who held funds at the named bank legitimately and who face access delays or losses as a collateral consequence of the action, a different analysis may apply, potentially generating a theft loss or bad debt deduction depending on the facts. Each situation will be specific, and firms advising affected clients should document the factual record carefully.
Information reporting for stablecoin transactions
The IRS treats stablecoins as property for federal tax purposes. Any stablecoin-denominated transaction, whether a payment, an exchange, or a receipt of proceeds, is potentially a taxable event. As enforcement scrutiny of stablecoin infrastructure increases, the likelihood that the IRS will use forfeiture-related disclosures to identify unreported taxable events also rises. Firms providing digital asset accounting software or manual bookkeeping services to clients with material USDT activity should ensure that the transaction record is complete, traceable, and consistent with any Form 1099-DA or other information return that may be required under the digital asset broker rules currently being phased in.
What Firms Should Do Right Now
This action does not require every firm to take dramatic steps, but it does require deliberate ones. The checklist below is drawn from the enforcement facts as reported and from existing FinCEN, IRS, and FASB guidance.
Immediate priorities
First, identify all client accounts and internal treasury positions that hold or recently held USDT. Second, check whether any fiat settlement or custody flows for those positions involved the named institution. Third, review your counterparty risk policy to confirm whether a civil forfeiture filing against a banking counterparty triggers an automatic escalation or re-review requirement. If it does not, that gap is worth addressing before the next enforcement cycle.
Fourth, brief your audit committees and risk committees. A federal forfeiture action of this scale against a bank linked to the dominant stablecoin issuer is a material market development. Boards and audit committees expect to be informed about enforcement events that could affect asset valuations, liquidity, or regulatory standing.
Fifth, review your crypto bookkeeping software or digital asset accounting software stack to confirm it can produce a full transaction history for USDT positions, segmented by counterparty and custodian. If a regulator or court asks for that data, you need it readily available in an auditable format. Our coverage of how US crypto enforcement is reshaping firm workflows sets out the broader operational context.

Frequently Asked Questions
Does this action mean USDT is illegal to hold?
No. The forfeiture action targets a specific bank and specific funds. Holding USDT remains legal for US persons and entities. However, firms should maintain clear records of the custodial and settlement rails their USDT flows through, because enforcement activity affecting those rails can create compliance documentation requirements even when the underlying holdings are legitimate.
What is civil forfeiture and how is it different from a criminal charge?
Civil forfeiture is a legal proceeding against the property itself rather than against a person. The government does not need to obtain a criminal conviction to pursue it. The standard of proof is lower than in a criminal case, which is why prosecutors sometimes use this route when the conduct involves complex financial structures across multiple jurisdictions.
How should auditors treat USDT balances on a client's balance sheet given this news?
Auditors should assess whether any USDT balances held during the relevant period were custodied or settled through the named bank or its correspondent network. If so, they should evaluate whether the fair value recorded was supportable and whether any disclosure of uncertainty or subsequent events is required. The ASC 350-60 framework requires fair value measurement at each reporting date, and any peg deviation during the period in question should be documented.
Could this affect Tether's ability to process redemptions?
The action is directed at a bank rather than at Tether's own reserves directly. However, if the bank held funds that formed part of the reserve infrastructure, there could be liquidity implications depending on how the forfeiture proceedings develop. Firms with large USDT positions should monitor the situation and ensure their liquidity planning accounts for potential redemption delays in stress scenarios.
What records should a firm retain in case regulators ask about USDT activity?
Retain blockchain transaction records showing wallet addresses, timestamps, and amounts. Retain the corresponding fiat settlement records showing the banking counterparties used. Retain any KYC and AML screening records for counterparties involved in the transactions. The IRS digital asset broker rules and FinCEN's existing recordkeeping requirements both point toward a minimum five-year retention period for most categories of this data.
