Why did oil prices rise after Trump's threat against Iran, and what immediate market impact was observed?

Oil prices rose because President Donald Trump threatened military strikes on Iran if Hezbollah continued attacking Israel, escalating geopolitical tensions just as US-Iran peace talks began in Switzerland — raising concerns about the talks’ viability and potential disruption to oil supply. Brent crude climbed as much as 2.2% to $82.30 a barrel at the open, while West Texas Intermediate neared $77; by 6:02 a.m. in Singapore, Brent for August settlement was 1.3% higher at $81.60 a barrel and WTI for August delivery rose 2.3% to $77.60 a barrel.

What is the status and significance of the US-Iran negotiations in Bürgenstock, and how are they linked to regional stability?

The high-level US-Iran negotiations in Bürgenstock, Switzerland, began amid a 60-day deescalation window initiated by Trump’s recent memorandum of understanding, but got off to a rocky start — Iranian media reported Tehran halted talks after Trump’s threat, though unnamed sources said negotiations were continuing. An official familiar with the discussions stressed that resolving the fighting in Lebanon is decisive for the talks’ success, as Iran has accused Israel of violating a truce there, and the broader war in the Middle East has already choked off supply from a region responsible for one-third of global oil production.
