Oil Markets in Focus Given Middle East Turmoil

June 18, 2025 | Chad Sheaffer, CFA, CAIA, Senior Research Analyst

Tensions in the Middle East spiked last week following a major escalation in the conflict between Israel and Iran, raising concerns over the stability of the global energy supply chain. To that point, the Strait of Hormuz — a vital chokepoint for global oil and gas flows that connects the Persian Gulf and the Gulf of Oman — has become increasingly fragile amid new reports of electronic interference with navigation systems and a tanker collision near the strait earlier this week. Roughly 20 million barrels of crude oil pass through the Strait of Hormuz each day, accounting for roughly 27% of the world’s maritime oil trade and 20% of total global oil consumption. Additionally, around 20% of global liquefied natural gas (LNG) is transported through the area, primarily from Qatar. Despite the heightened conflict and concerns that Iran could attempt to block the Strait of Hormuz, tanker traffic has remained relatively stable, with 111 vessels reportedly transiting through the Strait on June 15. This figure is down only slightly from 116 on June 12, and consistent with the recent daily range of 100 to 120 vessels.

Most of the material exported through the Strait of Hormuz is delivered to Asia, with roughly 84% of the crude oil and 83% of the LNG being shipped to the region last year. China, India, Japan, and South Korea accounted for approximately 69% of these flows, making Asia particularly vulnerable to supply shocks. While the U.S. has reduced its reliance on Middle East crude oil imports in recent years, with only 6% of its oil imports coming via the Strait, concerns remain for potential inflationary pressures and global GDP headwinds if regional conflicts escalate further.

In response to recent events, Brent crude oil has climbed to over $78 per barrel, and any further escalation could trigger additional volatility in energy prices and, by extension, global financial markets. Indeed, the Strait of Hormuz remains one of the most strategically significant and sensitive corridors for the global economy and investors should continue to monitor developments within the region given the potential for broader economic impacts.
