USDT▲$0.9991 issuer Tether has frozen four crypto wallets on the Tron network. US authorities confirmed the addresses are linked to Iran’s Central Bank.
The US Treasury’s Office of Foreign Assets Control (OFAC) had placed four crypto addresses on its sanctions list. Treasury Secretary Scott Bessent said the agency intends to “aggressively track financial flows and deny the Iranian regime access to revenues from its illicit schemes.“

How the USDT Freeze Happened and Who Controlled the Wallets
On-chain analyst Specter first reported the freeze, noting that the funds on the four addresses came from payment provider DTC Pay and exchange Bitso. According to OFAC, these crypto wallets are linked to the IRGC and Iran’s Central Bank.
The frozen amounts broke down as follows:
- TXGHxdYbGy574z5hBu4LNzq9NzjZQ9bhUf — $12.3M
- TJdgB1k6ot3f2nLuZug6D8eD3HavTmzmSK — $30.96M
- TAhwhFv3JpK39Nc2m8W5LPCcoTisutiRfp — $1.28M
- TFQbqaNbmq2xsVor2NbufLkYZvxFC9wC7k — $85.47M
The OFAC sanctions list was updated on July 14, 2026, adding six addresses–four of which contained frozen assets. Tether moved quickly to block the funds, consistent with its policy of cooperating with law enforcement.

Geopolitical Context: US-Iran Conflict Escalates
The freeze came amid a sharp escalation in the US-Iran conflict. The June ceasefire has collapsed.
The US has reimposed a blockade on Iranian ports, and CENTCOM announced a new wave of strikes near the Strait of Hormuz. The IRGC responded by striking US support facilities in Kuwait, a base in Jordan, and US Fifth Fleet assets in Bahrain.
Bessent emphasized that “the Treasury will not tolerate any support for the Iranian military” and will continue using all tools to cut off the regime’s financial channels.
