Optimism around the US-Iran ceasefire faded after Tehran announced that several terms of the agreement had been violated, causing stocks to fall and oil prices to rise on global markets.

Asian stock exchanges fell by 0.9%, while Wall Street and European indices recorded a 0.2% decline, ending a four-day global stock market rally. Brent crude oil jumped 2.4% and reached approximately 97 dollars per barrel, recovering after its worst drop in the past six years.

Restricted movement through the Strait of Hormuz continues to drive up oil prices. Analysts warn that the fragility of the ceasefire is already being tested on the ground.

Additionally, nearly one billion dollars was bet on falling oil prices just hours before the ceasefire announcement. A total of 8,600 contracts for Brent and American crude oil were sold around 19:45 GMT, raising questions about whether someone had advance information about the diplomatic breakthrough.

Direct negotiations between the US and Iran are scheduled for Saturday in Islamabad, where the American delegation will be led by Vice President JD Vance. US Treasury bonds remained stable after erasing earlier gains.
