Iran-US peace talks collapse, Hormuz closure threatens oil, shipping

The fragile ceasefire between the US and Iran has fractured as both sides rejected each other's latest proposals on May 11. Trump declared Iran's response, which called for an immediate end to war with guarantees against future attacks, sanctions relief, and unfrozen assets, as "totally unacceptable." Iran's foreign ministry spokesperson countered that the US has "unreasonable demands." The impasse prolongs effective closure of the critical Strait of Hormuz, through which roughly 40 percent of global traded oil normally flows, driving oil prices higher and threatening summer travel and logistics networks.

Oil jumped on Trump's rejection, with Brent and WTI both climbing as traders extended bets on sustained scarcity. India has asked citizens to conserve fuel and restrict gold purchases to preserve foreign exchange, while Prime Minister Modi urged working from home and online meetings following a COVID-era playbook. Thai refiners are sourcing crude from Africa and the Americas to reduce Middle East reliance. Private Chinese refiners have sought approval to cut run rates after Beijing previously ordered production at any cost. Qatar managed its first LNG shipment through Hormuz since the war began, a rare exception highlighting Pakistan's geopolitical leverage; most energy traders lack such negotiating power.

Jet fuel supply shortages are already threatening summer travel schedules in the Northern Hemisphere. The rupee, Philippine peso, and Thai baht have weakened sharply as energy import bills rise; India's refiners expect modest fuel price hikes within days.

European majors (BP, Shell, TotalEnergies) have reaped up to USD 4.75 billion in trading profits on the volatility, outpacing US counterparts. Defense and energy security names benefit from elevated risk premium, while energy importers and airlines face severe margin pressure.

The outlook hinges on whether Trump and Xi can use their May 13-15 Beijing summit to unlock diplomatic progress or whether the summit becomes a theater for further escalation signaling.
