A Senate Report Says 84% of Iran-Linked Crypto Wallets Used Tether. Is USDT Safe to Hold?
A Senate report just painted Tether as a financial lifeline for a sanctioned nation, but the story behind that striking statistic raises bigger questions about what it actually means for the millions of everyday holders sitting on USDT right now.

A recent Senate report by Senator Richard Blumenthal revealed that 84% of 846 crypto wallets connected to Iran used Tether (CRYPTO: USDT) almost exclusively. Senate Democrats have labeled this stablecoin a “lifeline” for the Iranian government. As a result, Blumenthal has urged Treasury and Justice Department officials to investigate potential sanctions and banking law violations. This report garnered significant attention on September 28, 2026.
Tether has pushed back against this portrayal, claiming it has helped freeze nearly $550 million linked to Iran. This raises an important question for anyone holding USDT—the largest dollar stablecoin, with a market value of around $184 billion—about whether the Senate’s findings on sanctioned wallets suggest risks for average users and whether holding USDT is safe.
The 84% Covers 846 Sanctioned Wallets, Not USDT’s $184 Billion Supply
A stablecoin like USDT is designed to maintain a consistent value of $1, typically backed by cash and short-term government securities. USDT is the most widely traded stablecoin, with about $69.5 billion changing hands in 24 hours—almost double Bitcoin (CRYPTO: BTC), which sees around $37.5 billion.
The high percentage of Iran-linked wallets using Tether likely reflects the need for a stable, quickly transferable, dollar-like asset in a sanctioned economy. These wallets were already under sanctions or investigation, so their choice of Tether highlights what specific actors prefer, but it doesn’t show how much of USDT’s daily trading volume comes from Iran.
A sanctioned entity’s choice of currency does not directly reflect the currency’s safety or legitimacy. Criminals, for instance, also use cash, and it wouldn’t be accurate to hold the issuing authority responsible.
USDT Held Its $1 Peg After the Report, and Tether Can Freeze Wallets
Despite the concerns raised in the report, USDT has maintained its $1 peg, trading at approximately $0.9997—suggesting holders do not view the report as a threat. Tether maintains this peg by redeeming tokens and by traders buying low and selling high.
Tether’s ability to freeze specific addresses adds a layer of security in controlling USDT transactions. While this means Tether can prevent the use of wallets linked to flagged addresses, it also poses a risk: if your wallet could be tied to a flagged address, it may be subject to freezing, regardless of your intentions.
Tron Balances and 2028 U.S. Platform Rules Carry the Largest Exposure
Most USDT transactions occur on the Tron network, meaning any new regulatory measures will likely impact Tron first. Currently, TRON (CRYPTO: TRX) trades around $0.33, with a market value of about $31.8 billion. Its price movement of just 1.8% over the last month indicates that current holders are not fleeing the platform in droves.
A bigger concern is U.S. regulatory developments. The GENIUS Act, which governs stablecoin regulations, is set to take effect by January 18, 2027. Starting July 18, 2028, U.S. platforms will be permitted to offer only stablecoins from approved issuers, affecting Tether, which operates outside the U.S.
For those seeking a regulated option, alternatives like USD Coin (CRYPTO: USDC), valued at around $74.7 billion, or Ripple’s RLUSD (CRYPTO: RLUSD), valued at about $2.49 billion, are available. However, these options trade with less volume and remain vulnerable to exchange risks.
Is USDT Safe to Hold After the Senate Report?
In our view, USDT can be a reliable choice for short-term trading due to its strong liquidity and stability in maintaining its $1 peg. However, it may not be the best option for holding large amounts long-term. This caution stems from the potential legal actions resulting from the Treasury and Justice Department’s responses to the Senate’s inquiry, with no clear timeline for those developments.
Monitoring USDT’s market value and supply will be crucial. If USDT’s market value declines while USDC’s rises, it may indicate that holders are shifting to competitors for added security. Conversely, a stable or growing USDT supply may suggest holders are disregarding the report. Keep in mind that any balance held on the Tron network is more likely to be affected by new regulatory scrutiny.
