Why did Iran say it closed the Strait of Hormuz this weekend?

Iran declared the Strait of Hormuz closed on Saturday, citing alleged ceasefire violations after Israel continued strikes in southern Lebanon. Iran's military command called the closure the "first step" in response to what it described as breaches of commitments by the US and Israel.

What did Pakistan and Qatar say about the US–Iran talks in Switzerland?

Pakistan and Qatar, the mediators, said the talks were "positive" and reported encouraging progress. They announced a roadmap aimed at reaching a final agreement within 60 days, plus working groups covering nuclear issues, sanctions, and dispute resolution.

How is the Strait of Hormuz both "closed" and "open" at the same time?

Iran declared the strait closed, but US Central Command said 55 merchant ships transited it on Saturday, moving over 17 million barrels of oil. Iran now runs a permit system, so vessels effectively need its permission to pass, well below the pre-war average of 130–160 ships daily.

What does the Strait of Hormuz closure mean for oil prices?

The Strait of Hormuz carries roughly 20% of the world's oil, so threats to it can push prices up. Brent crude (NYMEX:BZ) fell about 2.3% when the deal framework was signed, and has dropped around 20% from its 2026 wartime highs as the conflict de-escalated.

How did stock markets respond to the US–Iran deal?

Stock markets rallied on the ceasefire news. Japan's Nikkei 225 (INDEXNIKKEI:NI225) and South Korea's Kospi (KRX:KOSPI) both hit all-time highs, gaining more than 2% and 1.7% respectively, as investors priced in relief from nearly four months of energy supply disruption.

JD Vance joins high‑stakes US–Iran peace push as Hormuz tensions threaten 20% of world oil

Written by Mahathir BayenaPublished Jun 22, 2026, 4:03 AM

JD Vance has flown into Switzerland to join Donald Trump’s envoys in 60‑day roadmap talks with Iran, after Pakistan and Qatar said negotiations were making “positive progress” on nukes and sanctions.

His arrival comes as Iran claims the Strait of Hormuz is “closed” while the US insists 55 ships passed in a single day, raising questions over how far Tehran’s new permit system can disrupt a chokepoint that handles about 20% of global oil flows.

With oil prices sliding roughly 20% from recent highs and Japan and South Korea’s stock markets hitting records on the peace headlines, investors are now betting that Vance’s role in the talks could be as important for markets as it is for Middle East diplomacy.
