What Happened
- Indian Oil Corporation (IOC) and Reliance Industries — both of whom purchased Iranian crude under a temporary US general licence — are settling trade payments in Chinese yuan (RMB) routed via ICICI Bank's Shanghai branch to seller accounts denominated in yuan.
- The arrangement represents India's first purchase of Iranian crude in approximately seven years (since 2019, when US secondary sanctions pressure led India to stop Iranian imports under the Obama-era JCPOA sanctions reimposed by the Trump administration).
- The temporary US waiver covered shipments loaded before mid-March 2026, and expires around April 19, 2026 — meaning no new Iranian crude purchases are expected once the waiver lapses.
- Indian Oil Corp reportedly bought approximately 2 million barrels of Iranian oil in April 2026, worth around $200 million.
- The yuan-routing mechanism was chosen to avoid US dollar clearing systems (which are under OFAC jurisdiction), insulating the transaction from direct US regulatory reach.

US OFAC Sanctions Framework and Secondary Sanctions
The Office of Foreign Assets Control (OFAC), a bureau of the US Department of the Treasury, administers and enforces economic and trade sanctions. OFAC can impose two types of sanctions: primary sanctions (which prohibit US persons and US dollar transactions from engaging with sanctioned entities) and secondary sanctions (which penalise non-US entities — including foreign banks and companies — for engaging with sanctioned countries or persons, even when no US person or dollar is directly involved). Secondary sanctions against Iran were progressively tightened from 2012 and reimposed in full from 2019, making it risky for any global financial institution to process Iran-related transactions regardless of the institution's nationality.
- OFAC: Bureau of US Treasury Department; administers sanctions since 1950 (formalised under Trading with the Enemy Act)
- Primary sanctions: Apply to US persons and dollar-denominated transactions
- Secondary sanctions: Apply to non-US entities engaging with sanctioned counterparties
- Iran oil sanctions (reimposed 2019): "Maximum Pressure" policy; target Iran's petroleum revenues
- General licence: Temporary authorisation granted by OFAC permitting otherwise-prohibited transactions for a defined period
- The April 2026 waiver covered tankers loaded before approximately March 15, 2026
Connection to this news: India's choice to pay in yuan via ICICI Bank's Shanghai branch — rather than in US dollars — is a deliberate strategy to keep the transaction outside OFAC's jurisdictional reach over dollar clearing, exploiting the distinction between primary and secondary sanctions enforcement.
Yuan-Denominated Trade Settlement and De-Dollarisation
The Chinese renminbi (yuan/RMB) has been progressively internationalised since 2016, when it was included in the IMF's Special Drawing Rights (SDR) basket. China has established the Cross-Border Interbank Payment System (CIPS) as an alternative to SWIFT for yuan-denominated international transactions, reducing dependency on the US-controlled SWIFT network. For commodity trade involving sanctioned counterparties, yuan settlement is attractive because: (i) CIPS operates outside SWIFT's compliance infrastructure; (ii) payments clear through Chinese banks in Shanghai or Hong Kong rather than US correspondent banks; (iii) this reduces the transaction's exposure to OFAC jurisdiction over dollar clearing. India has explored similar yuan/rupee settlement frameworks for Russian crude imports since 2022.
- Yuan's SDR inclusion: October 2016 (IMF SDR basket — USD, EUR, CNY, JPY, GBP)
- CIPS (Cross-Border Interbank Payment System): China's alternative to SWIFT for yuan transactions; launched 2015
- SWIFT: Society for Worldwide Interbank Financial Telecommunication; based in Belgium; subject to US/EU regulatory pressure
- ICICI Bank's Shanghai branch: Acts as the clearing bank in China for the yuan payments to Iranian sellers
- India-Russia rupee-ruble framework: Parallel example from 2022-23 for sanctions evasion-proofing
Connection to this news: Using ICICI Bank's Shanghai branch to route yuan payments is operationally equivalent to using a Chinese bank — it keeps US dollar exposure near zero and thereby reduces secondary sanctions risk for both Indian refiners and their banking partner.
India's Strategic Autonomy in Energy Sourcing
India's energy import policy has consistently prioritised supply security and cost over geopolitical alignment, a posture it describes as "strategic autonomy." This was demonstrated starkly in 2022-23 when India dramatically increased Russian crude imports after Western sanctions (following Russia's invasion of Ukraine) sharply discounted Urals crude. The Iranian crude purchase follows a similar logic: the temporary US waiver created a narrow window for cost-advantaged crude acquisition, and India moved quickly to utilise it. India balances these purchases against its broader relationship with the US, typically reducing such purchases when diplomatic costs rise above the economic benefit.
- India's crude oil import dependency: ~85% of consumption imported
- Russian crude share (FY 2024-25): approximately 35-40% of India's crude imports (a dramatic rise from <1% pre-2022)
- Iranian crude: India was among Iran's top customers before 2019; imported ~25 million tonnes/year at peak
- Payment innovation for Russian crude: Rupee-ruble mechanism, dirham settlement, yuan settlement
- India's stated position: Purchases governed by national energy security needs; no illegality under Indian law
Connection to this news: The yuan-via-ICICI mechanism is a financial innovation born of the Russian crude experience, now applied to the Iranian context — demonstrating how India adapts its trade finance architecture to geopolitical constraints.
