A recent BBC headline, “How the West is helping Russia to fund its war on Ukraine,” published on May 30, 2025, presents a familiar narrative: Russia, reportedly awash in foreign currency from its fossil fuel sales, is using these “Western billions” to bankroll its ongoing war. The article starkly points out that “Ukraine’s Western allies have paid Russia more for its hydrocarbons than they have given Ukraine in aid,” highlighting a staggering €883bn earned by Russia since February 2022, despite sanctions.

While the sheer scale of these export revenues is undeniably jarring, and the moral implications of such purchases are deeply unsettling, the BBC’s analysis of Russia’s war funding misses a crucial economic point. The narrative that Russia needs these euros and dollars to pay its soldiers, forge tanks, or churn out shells for military use oversimplifies the fundamental realities of sovereign currency.

The Rouble Reality: Russia’s Domestic Spending Power

An elementary truth often overlooked in much mainstream analysis, including this BBC piece, is that Russian oil and gas companies do not pay their taxes to the Russian government in US dollars or euros. They pay in Russian roubles.

When these energy giants receive foreign currency (FX) from their exports, that FX does not directly inflate the Russian government’s capacity to spend within its economy. Instead, these companies typically convert their FX earnings into roubles – often through tied corporate banks like Gazprombank, the Central Bank of Russia or the National Wealth Fund. These institutions then absorb the foreign currency, issuing the necessary roubles back to the companies, which are then used for domestic obligations, including their tax bills.

Crucially, as the sole issuer of the rouble, the Russian state does not need to earn foreign currency to spend in its own currency. The primary constraint on domestic war spending isn’t a shortage of FX reserves; it’s the availability of real resources: the labour, the production capacity, the raw materials, and the technology. If Russia can produce something domestically, it can, in rouble terms, afford it.

If Oil Sales Dry Up, Does the War Machine Stop? Not Necessarily.

The BBC article strongly implies that cutting off Western purchases of Russian oil and gas would significantly hamper Russia’s ability to fund its war. While a loss of FX revenue would certainly impact Russia’s capacity to import from certain nations, it does not inherently shackle its ability to fund domestic production.

Consider a scenario where no country purchases Russian oil. The Russian government could still instruct its energy companies to produce oil, even without external buyers. Instead of earning FX and selling the FX to the Central Bank in exchange for roubles, the oil firms could sell the oil directly. The oil might sit unused or even be discarded, but the capacity to pay domestic arms manufacturers or soldiers in roubles would remain intact.

What truly matters isn’t the export revenue itself but whether Russia can acquire the necessary imports to fuel its war machine. If it can substitute foreign components domestically or source them through alternative channels, then export revenues become a secondary concern.

Sanctions: The Complex Reality of Restricting Imports

This brings us to the actual strategic aim of sanctions: to limit Russia’s access to vital imported goods and technology. The theory is sound: without advanced components like microchips or precision tools, Russia’s military-industrial complex could, in time, degrade.

However, this strategy faces significant real-world hurdles. While FX is undoubtedly useful for imports from the West, its importance diminishes as Russia’s trade with China and other non-Western partners booms. Much of Russia’s external trade now bypasses the dollar or euro, often conducted in national currencies like the yuan. If China is willing to supply goods and extend credit in CNY, then a shortage of Western FX becomes far less of a bottleneck.

Furthermore, a genuinely global embargo is impractical. While over 50 countries have imposed some form of sanctions on Russia, the vast majority of the world – particularly in the Global South – have not. Major economic players, such as China and India, continue to trade with Moscow and, in some cases, have even strengthened these relationships. Given China’s pivotal role in global supply chains, the ability of Western powers to pressure Beijing into economic disengagement is, at best, limited.

The Geopolitical Dimension: A Multipolar World Limits Sanction Efficacy

The BBC article briefly touches on the “refining loophole,” but it largely overlooks the broader geopolitical currents at play. Western sanctions now operate in a multipolar world. When Western markets close their doors, Russia pivots to other major economies. As long as nations like China and India refuse to join the sanctions regime, Russia will maintain access to both markets for its exports and crucial sources for its imports. Sanctions undoubtedly increase friction and costs, and they do restrict access to specific high-tech items, but they are highly unlikely to deliver a knockout economic blow.

Repeating Flawed Narratives Doesn’t Help

For the Western public, a clear and unvarnished understanding of these economic and geopolitical forces is essential. While the moral objection to financing an aggressor through energy purchases is valid and deeply felt, the actual mechanisms of that financing and the true effects of sanctions demand far greater rigour. Framing Russia’s FX income as the sole or primary enabler of its war effort fundamentally distorts the reality.

Similarly, overestimating Western leverage over global trade networks and underestimating Russia’s economic adaptability leads directly to misguided expectations and ineffective policy. The real challenge is to comprehend and engage with a multipolar world where economic power is diffuse, alliances are fluid, and Western dominance is no longer assured. Crafting genuinely effective long-term strategies requires not just moral clarity but profound economic literacy.
