US Tightens Iran Crypto Net: New Sanctions on Shelbit and Aban Tether

The U.S. Treasury has imposed fresh sanctions on Shelbit and Aban Tether to curtail Iran's access to the crypto ecosystem.

Scope of the New Sanctions

OFAC designated Shelbit as an Iran‑based crypto exchange and Aban Tether as a Tether (USDT) liquidity provider, prohibiting any direct or indirect ties to the U.S. financial system.

Liquidity Shock and TVL Impact

■$250 million TVL held on Shelbit, down 18% over the past 30 days.

■Aban Tether processed $1.2 billion in volume, but anticipates a 22% decline post‑sanctions.

■Iran‑originated crypto outflows could drop by 35%, tightening regional liquidity flows.

■The U.S. measures affect roughly 4% of global DeFi protocols, introducing modest strain on liquidity pools.

Ripple Effects on Layer‑2 and Cross‑Chain Solutions

The sanctions may restrict Iranian users from accessing Polygon, Arbitrum, and Optimism, potentially reducing daily active users (DAU) on these networks by 5‑7%.

Markets view OFAC's move as a strategic effort to sever Iran‑centric crypto pipelines while safeguarding U.S‑aligned liquidity providers. In the short term, we expect a modest liquidity squeeze and heightened volatility in certain DeFi tokens; over the longer horizon, the regulatory push could usher in greater transparency and attract more institutional capital to the sector.
