The single most important cause of the crash was the US-Iran interim ceasefire deal announced in mid-June 2026. The agreement led to the reopening of the Strait of Hormuz on around June 17, ending months of blockade during the US-Iran conflict .
The reopening released millions of barrels of stranded crude from the Middle East Gulf, described by analysts as a "mini tsunami" of oil flooding global markets . Middle East oil transit and production resumed faster than most analysts had predicted . HSBC researchers called it a "mini-glut" of oil entering a market with already weakened demand .
Brent crude fell roughly 42% from its April peak of $126 to near $70 by late June 2026, pulling all crude benchmarks — including Urals — sharply lower . By early July, Brent stood at $70.82 per barrel, erasing more than 38% from its peak .
Even as the Hormuz reopening was already driving prices down, the seven core OPEC+ members (Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, and Oman) agreed to successive monthly quota hikes of 188,000 barrels per day — approved for July 2026 , and again for August 2026 . The cumulative increase reached nearly 800,000 b/d since April .
Analysts questioned whether OPEC+ could find buyers for the extra crude, noting that Asian refiners — particularly in India and China — were cutting purchases . Kpler tracking data showed that Indian imports of Russian crude in June were just 5.31 million bpd, as a "buying strike" continued into July .
While Brent fell to around $70-72/barrel in late June, the Urals discount widened to approximately $22/barrel relative to Dated Brent . This discount pushed Urals well below the $59 budget line and toward the $42 level reported in early July . By early July, Urals was averaging $41.66 a barrel at Russia's western ports — back to pre-Middle East war levels .
The discount reflected both the broader oil price decline and specific pressure on Russian crude as Asian buyers had more options with Middle Eastern supply restored .
The supply wave from Hormuz hit at a time when the market was already expected to swing back into oversupply . Fitch Ratings had projected a return to surplus conditions even before the ceasefire, and the rapid reopening accelerated that timeline . Weaker demand from Asian refiners weighed on Urals prices specifically, with the grade trading at a discount of about $2-$3 per barrel to Brent for July and August deliveries to India and China .
Russia's 2026 federal budget was constructed on an assumed Urals crude price of $59/barrel, consistent with market levels at end-February 2026 . During the Hormuz closure in April, Urals surged to $116 — a 13-year high — briefly delivering a windfall to Russian state coffers and pushing the tax price above budget targets for the first time since January 2025 .
By late June 2026, Urals had fallen below the $59 budget benchmark as the Hormuz reopening restored normal flows of Middle Eastern oil . By early July, Urals was trading around $42 — a collapse of more than half from the April peak .
Russia's Accounts Chamber has already flagged that 2026 budget revenues face a shortfall of roughly $29 billion compared to initial projections due to plunging energy revenues .
Oil and gas revenues remain the single largest source of federal income, contributing approximately 20% of central government revenue . Even at $90/barrel earlier in the year, analysts noted the budget was not balanced . With Urals now at roughly $42 — and with a sustained $20+ discount to Brent — Moscow faces a widening budget deficit, lower tax receipts from oil exports, and increased pressure on the ruble and reserve funds.
The US-Iran ceasefire remains fragile. Several analysts warn that renewed hostilities could close the Strait of Hormuz again and send prices surging back, meaning the $42 Urals level could be temporary . The market is pricing in relief, but the underlying geopolitical risk is far from resolved .
