India’s major oil refiners have begun settling purchases of Iranian crude through Chinese yuan rather than US dollars, with ICICI Bank routing transactions via its Shanghai branch to seller accounts denominated in the Chinese currency, according to sources familiar with the arrangement. The shift represents a significant structural change in how Indian companies are managing sanctioned-market transactions, reducing exposure to dollar-based payment systems that carry heightened regulatory and compliance risks under American sanctions regimes.
The development underscores the deepening financial integration between India and China despite broader geopolitical tensions, and reflects the growing reality of a fragmented global payments ecosystem. With the United States maintaining comprehensive sanctions on Iran’s oil sector since 2018, Indian refiners—among the world’s largest buyers of Iranian crude—have long navigated a complex compliance maze. Using yuan instead of dollars eliminates the need to clear transactions through US banking infrastructure, a primary enforcement mechanism for American sanctions. ICICI Bank’s Shanghai branch serves as the intermediary, leveraging China’s willingness to maintain financial channels with Iran and positioning Chinese currency as a de-facto alternative settlement mechanism for trade between Asian nations seeking to circumvent dollar-dependent payment rails.
The economic stakes are substantial. Iran has sold crude to Indian refiners at significant discounts relative to global benchmarks, making Iranian oil critical for maintaining India’s refining margins and domestic fuel prices. In fiscal year 2024, India imported approximately 13 million barrels from Iran despite sanctions—a lifeline for both Iranian revenues and Indian refinery operations. By conducting settlements in yuan, Indian refiners reduce their vulnerability to US Treasury enforcement actions, regulatory fines, and potential secondary sanctions that have historically targeted banks processing Iran-related transactions. Simultaneously, the arrangement strengthens yuan liquidity and usage in South Asian commerce, advancing Beijing’s long-term currency internationalization objectives without requiring explicit government coordination.
The mechanics of the transaction flow reveal careful structuring. Rather than converting rupees to dollars and routing through New York clearing houses, ICICI Bank accepts rupee deposits from refiners, converts them to yuan at its Shanghai branch, and transfers yuan-denominated funds directly to Iranian seller accounts. This creates a closed-loop system minimizing touchpoints with dollar-based correspondent banking networks. Chinese banks, operating under Beijing’s more permissive interpretation of Iran sanctions compliance, facilitate these transactions with minimal friction. The arrangement also benefits from the yuan’s growing acceptance in crude oil markets; Saudi Arabia, the world’s largest crude exporter, began accepting yuan payments from Chinese buyers in 2022, establishing precedent for non-dollar settlement in energy markets.
For Indian refiners, the calculus is straightforward: operational risk reduction outweighs any currency conversion costs associated with yuan settlement. Companies including Indian Oil Corporation and Bharat Petroleum have historically absorbed significant compliance costs, legal fees, and insurance premiums to manage dollar-based Iran transactions. Yuan settlement transfers much of this burden to the banking intermediaries. However, the arrangement also creates new exposures: refiners now hold yuan liabilities and face exchange rate volatility between rupee and Chinese currency. Should US sanctions policy tighten further—potentially targeting yuan transactions or imposing secondary sanctions on ICICI Bank—the strategy could unravel rapidly, leaving refiners without alternative payment routes into Iran.
The broader implications extend beyond bilateral India-Iran trade. The shift signals how sanctions-targeted economies and their trading partners are systematically rewiring financial infrastructure to reduce dollar dependency. Russia, similarly sanctioned, has accelerated yuan and ruble settlement mechanisms with China and India. If this pattern accelerates across multiple sanctioned regimes and their partners, it could gradually erode the dollar’s role in commodity trade settlement—traditionally one of its most durable demand anchors. For the US dollar and American financial dominance, the trend represents a slow-motion challenge rather than an immediate threat, but it demonstrates how comprehensive sanctions regimes inadvertently incentivize alternatives to dollar infrastructure. Indian policymakers appear to view this pragmatically: enabling refiners to access cheaper Iranian crude supports domestic inflation control and fiscal management, while the yuan settlement mechanism avoids triggering fresh sanctions exposure.
Going forward, watch for three developments: whether additional Indian refiners adopt similar yuan-based settlement structures, potentially expanding the arrangement’s scale; whether the US Treasury responds with sanctions or regulatory warnings targeting yuan transactions with Iran; and whether other South Asian countries—particularly Bangladesh and Pakistan, which also import Iranian energy—adopt comparable mechanisms. The sustainability of this arrangement depends critically on ICICI Bank’s ability to maintain banking relationships in both India and Shanghai without triggering US regulatory action. Any shift in US policy toward secondary sanctions on yuan transactions could force a rapid unwind, making this a high-stakes gamble on the durability of current sanctions enforcement priorities.
