Oil Prices Plunge After US-Iran Ceasefire

Broader Markets Rallied as Oil-Driven Inflation Fears Eased

Equity markets broadly rallied as lower oil prices eased inflation fears. U.S. stock futures climbed up to 1.7% early Monday, with the S&P 500 and Nasdaq pointing higher . The Dow Jones Industrial Average rose 0.51% to 52,210, and the S&P 500 edged up 0.02% to 7,413, breaking a four-session losing streak. The Nasdaq slipped 0.18% to 24,932 on semiconductor weakness . Indian benchmarks (Sensex, Nifty) surged as crude-import-dependent economies welcomed the drop . The U.S. dollar fell against the euro as oil prices eased , and gold rose modestly to around $4,092/oz . Markets were described as "snapping a multi-day losing streak" as the ceasefire relief offset lingering tech-sector concerns .

Investors viewed the lower oil prices as removing a major source of potential energy-driven inflation, which also reduced pressure on central banks . "Oil's sharp retreat at the Monday open did more than knock a few dollars off the barrel. It loosened the geopolitical knot that had been tightening around equities, currencies, bonds and central banks for most of July," said Stephen Innes of SPI Asset Management .

What the Ceasefire Means for Shell and BP Earnings

The Q2 reporting period covers April–June 2026, when oil prices were elevated due to the Iran conflict. The post-ceasefire price collapse happened on July 27 — after the quarter ended. So Shell and BP's Q2 results will still reflect the war premium. However, their forward guidance and Q3 outlooks will be significantly impacted by Monday's price rout if the ceasefire holds and the supply-risk premium continues to unwind.

Shell (earnings due July 30, 2026)

Shell's Q2 2026 picture is a tale of two forces. On one hand, Shell expects significantly higher gas trading profits in Q2 compared to Q1, and stronger refining margins have lifted its quarterly outlook . On the other hand, the Middle East conflict knocked out Shell's Pearl gas-to-liquids facility in Qatar after a March attack on Ras Laffan Industrial City. This cut Integrated Gas production guidance to 610,000–650,000 boe/d from 909,000 in Q1 — a roughly one-third decline .

Shell's Q1 2026 adjusted earnings were $6.9 billion — consensus-beating results supported by "significantly higher trading and optimisation" profits as the Iran conflict drove oil price surges and unprecedented market volatility . Q2 is shaping up similarly: stronger downstream and trading profits are partially offsetting upstream volume losses, but the post-ceasefire oil-price collapse on Monday raises questions about Q3 revenue prospects .

BP (earnings due August 4, 2026)

BP issued a trading statement on July 14 that pointed to strong Q2 earnings supported by elevated energy prices during the quarter. The company expects oil price realizations to boost earnings by $1.8–2.1 billion, gas & low-carbon by $0.5–0.7 billion, and refining margins by $1.2–1.4 billion . Reported upstream production is forecast to fall to 2,170–2,220 mboe/d (from 2,339 in Q1) due to seasonal maintenance in the Gulf of America and Middle East disruption . BP also flagged a $1 billion impairment related to the conflict, and oil trading was expected to be slightly higher than Q1 .

Brent averaged $103.85/barrel in Q2 2026 compared to $81.13/barrel in Q1 , so BP's Q2 results will benefit directly from that price environment. The critical question for both companies is whether the ceasefire holds — if the supply-risk premium continues to unwind into the third quarter, the earnings tailwind from elevated crude prices will reverse sharply.

Key Takeaways for Investors

• The U.S.-Iran ceasefire on July 27 triggered the largest single-day oil price drop in months, unwinding a significant portion of the war premium built into crude since late February.
• Energy stocks were the worst-performing sector, while the broader market rallied on reduced inflation fears and lower gasoline prices.
• Shell and BP are set to report strong Q2 results for the period ending June 30, which benefited from the conflict-driven price surge. Their forward guidance for Q3 will be the critical signal for whether the ceasefire-driven price collapse changes their outlook.
• With Brent crude now trading below $90/barrel compared to its Q2 average above $100, the earnings trajectory for the second half of 2026 depends heavily on whether the geopolitical détente becomes permanent.
