Iran sanctions fight moves into crypto as USDT becomes part of the financial plumbing

<p class="text-align-justify" style="text-align: justify;">The sanctions fight against Iran isn't just playing out through traditional means anymore. While oil exports and banks remain the bigger pressure points, we are starting to see stablecoins become part of the machinery used to move money around those restrictions.</p><p class="text-align-justify" style="text-align: justify;">For me, that's the biggest takeaway from a new report by Democratic investigators on the US Senate Permanent Subcommittee on Investigations. The report looked at 846 crypto wallets sanctioned or targeted for seizure over links to Iran and its regional proxies, finding that <a href="https://www.blumenthal.senate.gov/newsroom/press/release/blumenthal-releases-psi-report-detailing-how-lutnick-linked-crypto-firm-tether-props-up-irans-shadow-banking-system" rel="follow">84% had transacted exclusively or nearly exclusively in USDT</a>.</p><p class="text-align-justify" style="text-align: justify;">So, why does that matter exactly?</p><p class="text-align-justify" style="text-align: justify;">Let's try to frame things in a simpler manner. Now, USDT is essentially a digital token designed to track the US dollar. Instead of asking a bank to send dollars across borders and through the traditional banking system, USDT can be transferred directly between crypto wallets.</p><p class="text-align-justify" style="text-align: justify;">With that in mind, you can see why it might appeal to a country facing heavy restrictions on access to international banks and dollar payment systems.</p><p class="text-align-justify" style="text-align: justify;"></p><p class="text-align-justify" style="text-align: justify;">Having said that, US authorities are hardly blind to this either. The Treasury's Operation Economic Outcast has sought to target Iran's digital-asset infrastructure alongside the more familiar channels of oil exports and traditional finance.</p><p class="text-align-justify" style="text-align: justify;">However, this is where things get a bit more complicated.</p><p class="text-align-justify" style="text-align: justify;">USDT might move outside the rails of traditional banking, but it doesn't mean that it is beyond anyone's control. Tether is a centralised issuer and can freeze tokens held in identified wallets.</p><p class="text-align-justify" style="text-align: justify;">In fact, <a href="https://tether.io/news/tether-has-supported-nearly-550-million-in-iran-linked-usdt-freezes-as-u-s-expands-sanctions-campaign/" rel="follow">Tether announced that it has supported the freezing of roughly $550 million in Iran-linked USDT during 2026 already</a>. And that includes more than $344 million across two wallets in April and over $130 million across another four in July. The company also argued that public blockchains can actually help authorities trace illicit flows and intervene once relevant addresses are identified.</p><p class="text-align-justify" style="text-align: justify;">I would say that the tension we're seeing is what is keeping things rather interesting in this space.</p><p class="text-align-justify" style="text-align: justify;">At its core, stablecoins can provide dollar-like liquidity without every payment passing through a bank. But as stablecoins move deeper into global payments, it isn't all too surprising to see sanctions follow them. And even more so when issuers such as Tether can also act as another enforcement point.</p><p class="text-align-justify" style="text-align: justify;">As such, the question moving forward isn't so much whether crypto sits inside the financial system. It is more about how governments and stablecoin issuers police that new layer of it.</p><p class="text-align-justify" style="text-align: justify;"></p> This article was written by Justin Low at investinglive.com.
