Risk off, as expected.
Weekend developments in the US–Iran conflict reinforced just how fragile the ceasefire remains, with fresh maritime incidents, stalled diplomacy, and renewed pressure on energy markets.
The most immediate escalation came after the US military intercepted and seized an Iranian-flagged cargo vessel attempting to run the American blockade near Bandar Abbas. Washington said the ship was taken into custody after being fired upon, while Iran condemned the move as “armed piracy” and warned it would retaliate. The incident marks a significant deterioration in trust and raises the risk that the already tenuous ceasefire could collapse before its scheduled expiry.
At the same time, diplomatic efforts appear to be faltering. Iran formally rejected participation in a second round of US-led talks, citing the ongoing blockade, escalating rhetoric from Washington, and what it described as excessive demands. While Pakistan has been preparing to host negotiations in Islamabad, including heightened security measures and logistical arrangements, the prospects for meaningful dialogue now look increasingly uncertain.
The standoff continues to centre on control of energy flows. The United States has maintained its blockade of Iranian ports, while Iran has alternated between reopening and restricting transit through the Strait of Hormuz. Reports over the weekend indicated that vessels attempting to transit the Strait were turned back, reinforcing the reality that shipping conditions remain unstable despite intermittent signals of reopening.
Market reaction underscores the sensitivity of the situation. Oil prices rebounded sharply after last week’s sell-off, with Brent and WTI both rising strongly as traders reassessed the likelihood of a sustained disruption. While more than 20 vessels were reported to have transited the Strait on Saturday, the highest since early March, confidence remains fragile, with shipowners hesitant to rely on assurances that safe passage will hold.
Taken together, the weekend’s developments highlight a market caught between headline-driven optimism and persistent structural disruption, with the underlying reality pointing to continued volatility in energy flows.

The key takeaway is that physical disruption risk remains intact despite headline-driven swings. The ship seizure and breakdown in talks reinforce that neither side is stepping back, keeping Hormuz effectively in a state of managed instability. This supports oil prices, sustains elevated freight and insurance costs, and keeps inflation risks alive
