Iran’s Central Bank Bought $507M in USDT to Support the Rial and Settle Trade
Blockchain analytics firm Elliptic says Iran’s Central Bank (CBI) accumulated roughly $507 million in Tether (USDT) during 2025 to defend a collapsing rial and help settle international trade. Purchases concentrated during extreme currency volatility when the rial lost about half its value in eight months. The CBI reportedly used local exchange Nobitex to convert USDT into rials in operations resembling open-market intervention. After a June 2025 security incident at Nobitex — when about $37 million in USDT linked to CBI-related wallets was frozen by Tether — the bank shifted tactics, moving assets off TRON onto Ethereum and using cross‑chain bridges, DEXs and other exchanges to move and convert funds. Elliptic highlights that issuer-controlled stablecoins remain subject to freezes and blacklisting, reducing their equivalence to hard dollar reserves. Separately, Chainalysis reported Iran’s crypto ecosystem surged past $7.8 billion in 2025 as local users increasingly use bitcoin and other digital assets as inflation hedges amid protests and economic instability. Traders should note three practical takeaways: (1) state-driven USDT demand can boost local stablecoin liquidity and change regional flows; (2) issuer freezes or regulatory actions can abruptly remove liquidity from on-chain markets; (3) large state-led moves leave clear on-chain traces, which can influence exchange flows and market sentiment.
Neutral
Impact on USDT price is likely neutral overall. Positive factors include meaningful demand for USDT from a sovereign actor, which can tighten regional stablecoin liquidity and support USDT flows in local markets. That demand can be viewed as bullish for USDT usage and short-term volume. Negative/countervailing factors include demonstrated issuer control: Tether froze roughly $37M linked to CBI wallets, showing that USDT can be blacklisted and that large on-chain reserves are vulnerable to freezes and regulatory pressure. That reduces the perception of USDT as equivalent to uncontrollable dollar reserves and caps long-term upside. Additionally, the visible on-chain trail of state operations increases market scrutiny and may prompt exchange-level controls, which can intermittently remove liquidity. Net effect: temporary spikes in regional demand and volume, but limited price upside and increased tail-risk from freezes — a neutral classification for USDT price. For related assets (e.g., BTC) there may be localised buying as an inflation hedge, but this story does not materially alter global BTC supply-demand fundamentals.
