TL;DR
Oil prices steadied near March lows on expectations of a deal between the US and Iran to reopen the Strait of Hormuz. The agreement, scheduled for signing in Switzerland, has boosted market confidence but uncertainties remain.
Oil prices held near their lowest levels since March on June 15, 2026, amid growing optimism that a deal between the US and Iran to reopen the Strait of Hormuz will be finalized this week. The agreement is expected to be signed in Switzerland on Friday, potentially easing tensions in the region and impacting global oil flows.
West Texas Intermediate (WTI) traded close to $81 a barrel, having fallen nearly 5% on Monday, while Brent crude hovered around $83. The decline followed reports of progress toward a deal between the US and Iran, which could see Iran’s oil exports resume and the Strait of Hormuz reopen, easing fears of supply disruptions.
US President Donald Trump publicly expressed confidence, stating that the waterway would be clear, and indicated that multiple routes are currently available for oil shipments. The anticipated signing in Switzerland marks a significant step toward easing regional tensions and stabilizing oil markets.
Market analysts note that while prices have stabilized near recent lows, the actual impact on global supply remains uncertain until the deal is officially signed and implemented, with some experts warning of potential volatility if negotiations falter.
Implications of the Iran-US Deal for Global Oil Markets
The potential reopening of the Strait of Hormuz could significantly increase oil supplies from Iran, one of the world’s major exporters, which has been constrained by sanctions. This development could lead to lower global oil prices and reduce geopolitical risks associated with the region. However, market reactions remain cautious as negotiations are still ongoing, and the deal has not yet been finalized.

Recent Oil Market Trends and Regional Tensions
Oil prices experienced volatility earlier this year amid geopolitical tensions in the Middle East, particularly around Iran and the Strait of Hormuz. The Strait is a critical chokepoint, through which about 20% of global oil trade passes. Previous efforts to negotiate a deal have faced setbacks, but recent diplomatic progress has renewed hopes for a resolution.
The US and Iran have been engaged in negotiations aimed at easing sanctions and restoring diplomatic relations, with the upcoming signing in Switzerland representing a potential breakthrough. Market participants have been closely watching these developments for signs of a supply increase that could impact prices.
“Market sentiment has improved significantly with the expected signing of the Iran-US deal, which could lead to increased supply and downward pressure on prices.”
