U.S. West Texas Intermediate oil fell below $84 a barrel on Friday after Iran announced the Strait of Hormuz was fully open. The price dip marked an 11% slide in the market, the steepest drop in weeks [2].

The move matters because the Hormuz corridor carries about a fifth of the world’s oil supply, and analysts had warned that a closure could choke up to 13 million barrels per day, sending prices soaring [3]. By reopening the waterway as part of a cease‑fire deal with Lebanon, Tehran removed the immediate threat of a major supply shock, allowing traders to recalibrate and bring down U.S. benchmarks.

"The Strait of Hormuz is completely open to commercial traffic," said Seyed Abbas Araghchi, Iran’s foreign ministry spokesperson, in a statement released to Business Times Online [3]. The announcement was quickly echoed in Washington, where President Donald Trump said, "The Strait of Hormuz is open for business," adding that the decision would help stabilize global markets [4].

Investors responded swiftly. By midday, WTI futures had slipped below the $84 mark, a level that had seemed secure just days earlier [1]. The decline was mirrored in Brent crude, which also shed more than 10% in value, underscoring how sensitive oil prices remain to geopolitical risk.

Energy analysts said the market had been pricing in a worst‑case scenario of a 13‑million‑barrel‑per‑day disruption, a figure that drove speculative buying in the weeks leading up to the announcement [3]. With the strait now declared open, that premium evaporated, prompting a rapid sell‑off.

"The statement reassured markets about uninterrupted transit through Hormuz," said Firstpost editorial staff, noting that the easing of supply concerns was the primary catalyst for the price plunge [5].

The broader context includes ongoing tensions in the Middle East, where recent clashes between Israel and Hezbollah raised fears of wider regional instability. While the cease‑fire agreement between Iran and Lebanon helped defuse one flash point, traders will continue to watch for any resurgence of hostilities that could again threaten the Hormuz corridor.

**What this means**

The sharp fall in U.S. oil prices illustrates how quickly markets can reverse when a single chokepoint is perceived as safe. With the Strait of Hormuz reopened, short‑term supply risk has receded, likely keeping gasoline and jet fuel costs lower for consumers in the coming weeks. However, the underlying geopolitical tensions remain, meaning the price floor could rise again if new threats emerge.
