Rupee-Rouble Exchange Rate Slides as Trade Imbalances and Settlement Challenges Persist

The INRRUB currency pair has fallen 16.8% over the past three months, as the rupee weakened sharply against the ruble. The decline reflects persistent trade imbalances between India and Russia, the effective breakdown of the rupee-rouble settlement mechanism, and changes in payment practices for Russian oil imports.

Trade Imbalances and Payment Frictions Remain Central

The dominant driver of the rupee’s depreciation against the ruble has been the unresolved trade imbalance between the two economies. India’s imports from Russia—primarily crude oil—have increased substantially, with bilateral trade reaching $70 billion in 2024 and India’s trade deficit with Russia ballooning to $57 billion. Efforts to settle this trade in rupees have stalled, as Russia is reluctant to accumulate further rupee balances that have limited international utility and cannot be easily repatriated or invested.

Attempts to create a permanent rupee-rouble settlement mechanism were suspended in mid-2026, leaving India to settle Russian oil trades increasingly in yuan or dirham. These alternative payment practices have further reduced the demand for rupees in trade settlement, reinforcing downward pressure on the currency pair.

Narrowing Oil Discounts and Shifting Settlement Practices Weigh on Rupee

The commercial incentive for India to import Russian oil has diminished as discounts on Russian Urals crude narrowed from $21 per barrel below Brent in July 2026 to 7%, and spot deals have replaced most long-term supply agreements. As Indian refiners shift to pay in yuan or dirham, the rupee’s relevance in bilateral trade settlement has declined. At the same time, the increased use of yuan for oil payments strengthens China’s currency in global energy trade and further reduces structural demand for the rupee.

These developments have reinforced the trend of rupee weakness relative to the ruble, as illustrated by the 16.8% decline in the currency pair over the past quarter. Volatility remains elevated, with the INR/RUB pair trading in a wide range of 0.9178–0.9920 in September.

Relative Policy and Capital Flows: RBI Versus Bank of Russia

Monetary policy and capital flows have also played a role in the rupee’s depreciation. The Reserve Bank of India has maintained its repo rate at 5.25% in recent months and intervened in FX markets to limit rupee volatility, drawing down reserves from $728 billion to $688 billion by mid-2026. Despite these efforts, persistent foreign portfolio outflows and a widening current account deficit have weighed on the rupee.

On the Russian side, the Bank of Russia has maintained tight policy, cutting its key rate to 15% in March 2026 and reducing daily FX sales, which has helped to stabilize the ruble. High oil prices, capital controls, and ongoing foreign currency sales from the National Wealth Fund have further supported the ruble’s external value, despite sanctions and external constraints.

Broader Market Dynamics and Structural Factors

The rupee-rouble exchange rate has been shaped not only by immediate trade and policy developments but also by longer-term structural challenges. The failed rupee-settlement mechanism and India’s persistent trade deficit with Russia have left Russia with a large rupee surplus and little incentive to accumulate further rupee assets. At the same time, global sanctions have forced Russia to diversify its trade partners and payment rails, while India’s reliance on imported energy and periodic capital outflows continue to expose the rupee to downside risk.

Correlations with energy prices remain important. The rupee and ruble are both sensitive to oil market volatility, with supply disruptions in the Middle East and shifting global energy flows contributing to swings in the currency pair. The move away from rupee settlements in favor of convertible currencies for Russian oil trade—especially the yuan—has had a persistent structural effect on the currency relationship.

With the market pricing in ongoing payment frictions, unresolved trade imbalances, and persistent capital flow risks, the outlook for the INRRUB pair will remain highly sensitive to developments in energy markets, trade policy, and central bank actions on both sides. Any material shift in settlement practices or capital flows could test the durability of the recent rupee weakness against the ruble.
