Global oil prices and financial markets move sharply as traders gauge developments in US-Iran ceasefire and de-escalation negotiations. Several reports say oil falls on optimism that a framework or truce deal could reopen the Strait of Hormuz and reduce the risk of disruption to a major global shipping route. That improves risk sentiment, with Asian stocks rising and currencies such as the US dollar weakening in some accounts. One outlet links the renewed downturn in crude to expectations of a lasting ceasefire, while another says prices drop toward around US$80 a barrel as the strait’s operational risk eases. Other coverage highlights the counterweight: uncertainty persists around the durability of any agreement and the negotiating outcome, which can still push prices upward. One report also notes that the Strait of Hormuz was effectively closed at points after earlier strikes and that it is the key factor driving energy market volatility. Separately, a report attributes an oil rebound to renewed fighting and rising tensions, described as the most significant escalation since an April ceasefire. Overall, the story centers on shifting expectations for de-escalation and supply security via the Strait of Hormuz.
