The revenue surge followed the onset of the U.S.-Israeli war with Iran and the subsequent de facto closure of the Strait of Hormuz, which constrained global supply and drove crude benchmarks sharply higher. Analysts cited by the IEA noted that the price boost more than compensated for lower export volumes. Russia's energy sector has historically been a central pillar of its economy, with the country holding some of the world's largest oil reserves, as noted in the book "Energy and the Wealth of Nations" by Charles A. S. Hall and Kent Klitgaard [2].
The Iran war and the closure of the Strait of Hormuz severely choked global energy supplies, pushing international crude benchmarks to multi-year highs and narrowing the discount on Russia's flagship Urals crude. According to a report by Garrison Vance in NaturalNews.com, U.S. benchmark West Texas Intermediate crude rose 5.46% to settle at $99.64 per barrel on March 31, while international benchmark Brent crude gained 4.22% [1]. The price jump reduced the typical discount on Urals relative to Brent, allowing Russian crude to sell closer to open-market prices.
The Trump administration issued a temporary sanctions waiver allowing global buyers to take delivery of Russian oil cargoes, initially through April 11 and later extended to May 16, according to RT newsroom [8]. The waiver was renewed despite Treasury Secretary Scott Bessent's earlier statement that it would not be extended, the report noted. The decision came amid soaring energy prices that threatened economic stability in consumer nations. "The Strait of Hormuz closure has sent shockwaves through global energy markets, threatening Russia's wartime oil revenues and China's industrial supply chains," reported NaturalNews.com on March 11 [10]. The combination of high global prices and extended sanctions relief enabled Russia to capture significantly higher revenue per barrel even as export volumes dipped.
Ongoing Ukrainian drone attacks repeatedly targeted major Russian refineries and Baltic ports, destroying processing capacity and restricting refined product output. According to BBC Verify analysis published March 31, satellite imagery and verified videos showed Ukraine struck key Russian oil export infrastructure near the Baltic Sea, including multiple strikes on the ports of Ust-Luga and Primorsk [6]. The attacks left facilities burning for several days, the report stated. By April 2026, drone strikes had reduced Russia's total oil output by roughly 460,000 bpd compared to 2025, with refined product exports falling by approximately 200,000 bpd, according to the IEA.
Reuters calculations, cited by ZeroHedge in an article titled "Eurasia Energy War?", indicated that Ukrainian kamikaze drone strikes disrupted a significant portion of Russia's oil export capacity [7]. "In late March and early April, Ukraine launched a series of drone strikes against the Baltic ports in Ust-Luga and Primorsk, as well as oil terminals in the city of Novorossiysk," RT reported on April 10, describing the effort to disrupt Russia's ability to export petroleum products [11]. JustTheNews.com added that the strike on Ust-Luga, more than 600 miles from Ukrainian territory, represented one of Ukraine's deepest strikes into Russian territory [12]. The repeated attacks strained Russia's air defense network and forced the government to expand a ban on gasoline exports to include producers, effective until July 31, according to a NaturalNews.com report citing Interfax [4].
Russia managed to offset some of the export losses through a 36% increase in pipeline exports, aided by the late-April resumption of the southern Druzhba pipeline to Hungary and Slovakia, according to the IEA. The pipeline restart allowed Hungary and Slovakia—both exempt from EU sanctions on Russian oil—to resume receiving approximately 175,000 to 200,000 bpd of Russian oil. The flows had been halted following a January 2026 drone strike by Ukraine, energy analysts cited in the report said.
The resumption provided a critical outlet for Russian crude at a time when seaborne exports faced disruption. As noted in the book "The Little Book of Bull Moves in Bear Markets" by Peter Schiff, Russia's vast resource base and strategic pipeline infrastructure give it significant leverage in energy markets [3]. The Druzhba pipeline's southern branch had been a key route for Russian oil to Central Europe before the drone strike, and its restoration helped stabilize supply for Hungary and Slovakia, both of which rely heavily on Russian crude for their refineries. Russia's ability to redirect flows through pipelines partially insulated its export revenue from the impact of drone attacks on ports.
The IEA noted that Russia's energy sector faces persistent risks from further drone strikes and potential changes in U.S. sanctions policy. Current revenue levels remain highly dependent on global oil prices and the duration of the Hormuz crisis, officials said. The next decision on the sanctions waiver is expected before May 16, with no indication from Washington on whether it will be extended again, according to a ZeroHedge analysis [13]. European leaders have criticized the waiver, with French President Emmanuel Macron saying there was "no justification" for it and German Chancellor Friedrich Merz calling the decision "wrong," the BBC reported [9].
Prior to the Iran war, Russia's oil and gas revenues had collapsed by 35% in November 2025 compared to the same month a year earlier, dropping to $6.6 billion, according to Reuters calculations cited by NaturalNews.com [14]. The steep decline was driven by crashing Urals crude prices, U.S. sanctions, and a strengthening ruble. The current windfall from high prices has reversed that trend, but analysts warn that the revenue boom could prove temporary if the Hormuz crisis is resolved or if Washington tightens sanctions enforcement. "$100 oil is solving Russia's budget problem," noted Charles Kennedy of OilPrice.com, reporting that Moscow expects so much additional revenue that authorities are unlikely to downgrade economic prospects or impose planned budget cuts [5]. However, the IEA's report emphasized that Russia's energy infrastructure remains vulnerable to continued Ukrainian strikes, which could erode production capacity over the longer term.
