Across the Atlantic, the downward trend was far less pronounced, with the Dow Jones losing 0.10% around 6:00 p.m. The White House incumbent confirmed that the truce would end Wednesday night, specifying that he would not reopen the Strait of Hormuz until a deal is reached. Meanwhile, J.D. Vance is expected to depart for Islamabad on Tuesday, according to the New York Times, while Tehran claims it has "not yet made a decision" regarding its participation in the talks.

The military situation has further hardened. Yesterday, the U.S. Navy forcibly intercepted an Iranian merchant vessel, marking an escalation in the naval standoff between the two belligerents. Since the start of the blockade on Iranian ports, 27 vessels have been turned away, according to the U.S. military.
Donald Trump once again adopted an offensive tone on Truth Social, referring to a "fair and reasonable deal" and threatening to strike Iranian energy infrastructure and bridges in the event of a refusal.

In this context, oil prices are rising sharply: Brent is up approximately 4% to 95.52 USD, driven by supply concerns.

Lizzy Galbraith, senior political economist at Aberdeen Investments, highlights the erratic nature of the negotiations: "Progress toward a lasting ceasefire between the U.S. and Iran, as well as the reopening of the Strait of Hormuz, remains a stop-and-go process. The truce, with its approaching deadline, remains extremely fragile. After appearing to agree on Friday to reopen the strait, the two sides quickly diverged, with Iran re-announcing its closure while the U.S. blockade continued. At this stage, whether a new round of negotiations will take place this week remains uncertain. This instability partly reflects the power vacuum in Tehran: with several key figures missing, it is unclear whether any authority is in a position to conclude a lasting agreement with Washington."

Conversely, EssilorLuxottica (-4.27%) suffered the sharpest decline on the index, penalized by a note from Bernstein lowering its price target. The broker highlighted structural risks, particularly those related to profound technological shifts in the sector.
