Iran-US ceasefire on life support; oil and inflation fears spike

The US-Iran ceasefire has deteriorated sharply as President Trump rejected Iran's peace proposals and publicly stated the agreement is on 'massive life support,' effectively signaling the conflict could reignite. The Strait of Hormuz, a critical chokepoint for global oil exports, remains closed with no clear path to reopening. Two Qatari LNG tankers have exited the strait after going dark, and Qatar has asked ships at its main LNG export facility to turn off transponders for safety. This effective blockade is sustaining elevated oil prices despite US Strategic Petroleum Reserve releases and record American exports partly offsetting the supply shock.

Central banks across Europe and Asia are now openly discussing the need for rate hikes if the conflict persists. The European Central Bank's Christodoulos Patsalides stated things are "pointing to June rate hike," while Germany's Nagel said the ECB "must act" if Iran war jeopardizes price stability. South Korea's 10-year bond yield spiked above 4% for the first time since late 2023 on rate-hike expectations tied to the oil shock. Emerging-market currencies and equities have sold off as traders reassess geopolitical risks.

The Strait of Hormuz closure is upending supply chains beyond energy. Japan's largest potato-chip maker is forced to use black-and-white packaging due to an ink shortage caused by the conflict. Shiseido is looking to swap oil-based inputs for plant-derived materials as supply chains fracture. Insurance scrutiny on private credit has tightened as geopolitical tail risks spike. Some traders note that while the short-term volatility benefits defensive sectors like gold and energy, prolonged conflict could trigger recession fears and a broad deleveraging across risk assets.

Market expectations remain split. Some traders believe the Trump administration will negotiate a resolution, citing his preference for dealmaking. Others warn that rising rhetoric and military posturing could spiral into direct escalation.

Equity futures are down 0.4% at the open Tuesday, signaling caution, though earnings strength is providing some support.
