Oil Prices and the Strait of Hormuz: Core Event
Brent crude fell from above $115 per barrel early in the week to $100.06, a 1.2 % decline, and later to $101.27, a 7.8 % drop, as Iran announced a review of the latest U.S. proposals to end the conflict. Pakistan’s Foreign Ministry said it expected an agreement “sooner rather than later,” reflecting its role as mediator. President Donald Trump added that the Strait of Hormuz could be “OPEN TO ALL” if Iran accepts the reported deal, signalling a possible reopening of the key shipping lane that has been blocked by the war.

Official Statements & Responses
President Trump indicated the strait could be opened to all commercial traffic pending Iranian acceptance of a deal. Pakistan’s foreign ministry spokesperson expressed optimism about a near-term agreement. McDonald’s CEO Chris Kempczinski warned that high gasoline prices and consumer anxiety over the Iran war could dent sales this spring. AMD chief executive Lisa Su attributed recent earnings beat to sustained AI-driven demand for data-center computing power.
Criticism & Opposition
Takashi Hiroki, chief strategist at MONEX, cautioned that market activity is concentrated in AI and semiconductor stocks, describing the situation as “a kind of bubble” where “only semiconductor stocks are being bought.”
Conflicting Reports & Gaps
The two market narratives—one of modest equity declines, the other of record-setting gains—cannot be reconciled from the available data, highlighting a gap in real-time reporting on investor sentiment. Details of the proposed Iran-U.S. agreement remain unspecified, and the timeline for any Strait of Hormuz reopening is unclear.
