Oil Prices Plunge as US and Iran Reach Deal to End Middle East Conflict
Crude oil prices fell approximately 4% on Monday following a finalized peace agreement between the United States and Iran. According to Pakistani mediator Shehbaz Sharif and US President Donald Trump, the deal ends military operations across the Middle East and reopens the strategic Strait of Hormuz to global shipping.
Why did oil prices drop on Monday?
Oil markets reacted sharply to the news of a permanent ceasefire. Brent crude, the global benchmark for August delivery, fell 3.89% to $83.93 per barrel. The US-based WTI crude saw a steeper decline, dropping 4.45% to $81.10 after an initial plunge of nearly 5% at the opening of Asian trades.
Stephen Innes, an analyst at SPI Asset Management, stated that the deal reduces the “risk premium” embedded in oil prices. This premium had driven costs higher since the conflict began in late February, as traders feared prolonged supply disruptions in the Persian Gulf.
What does the US-Iran agreement include?
The agreement establishes an “immediate and permanent” end to the war across all fronts, including operations in Lebanon. US President Donald Trump confirmed the finalization of the deal via his Truth Social platform, specifically highlighting the reopening of the Strait of Hormuz without transit fees.

Kazem Gharibabadi, Iran’s Deputy Foreign Minister, confirmed the end of military operations during a broadcast on state television. To formalize the pact, Pakistani Prime Minister Shehbaz Sharif announced on X that a signing ceremony will take place in Geneva on Friday, June 19.
The role of Pakistan as a key mediator was central to the negotiations, bridging the gap between Washington and Tehran to secure the ceasefire.
How will the reopening of the Strait of Hormuz impact the market?
The conflict had largely paralyzed shipping through the strait since February. Before the hostilities, an average of 140 ships transited the passage daily. While some traffic resumed recently, it remained well below normal levels.
According to Stephen Innes, a full reopening provides three immediate benefits to the energy sector:
- Reduced Uncertainty: Shipping companies can plan routes without fearing military interception.
- Insurance Relief: Maritime insurance markets, which spike during conflicts, are expected to stabilize.
- Supply Fluidity: The removal of transit fees and threats allows for a more efficient flow of crude to global refineries.
What risks remain for oil stability?
Despite the diplomatic breakthrough, physical obstacles remain. Innes warned that returning to normal traffic levels depends on the actual clearing of naval mines and the establishment of a credible security framework.
The transition from a signed paper in Geneva to safe waters in the Gulf isn’t instant. If mine-clearing operations stall or if security trust wavers, the “risk premium” may return to the market, potentially offsetting the current price drops.
Investors are now shifting their focus to International Energy Agency (IEA) data to see if global inventories will swell as Iranian oil returns to the market more freely.

Frequently Asked Questions
When will the US and Iran officially sign the deal?
The signing ceremony is scheduled for Friday, June 19, in Geneva, according to Prime Minister Shehbaz Sharif.

Why is the Strait of Hormuz so important for oil prices?
It is a critical chokepoint for 20% of the world’s crude oil. Any disruption there creates a supply shock that drives prices up globally.
Will oil prices continue to fall?
While the peace deal removes the immediate conflict premium, analysts like Stephen Innes suggest that long-term prices will depend on the speed of mine clearing and maritime security.
