Trump's Iran Ultimatum Sparks Market Uncertainty Amid Ceasefire Talks

Based on the sources provided, the U.S. and Iran are currently engaged in an active military conflict that began in March 2026, with oil prices surging over 60% due to fighting and a U.S. blockade around the strategic Strait of Hormuz. President Trump has issued ultimatums to Iran while peace talks are reportedly stalled, creating what investors describe as a critical week with "binary outcomes" of either an imminent deal or further escalation. A senior Iranian official has warned that the war is "likely" to restart after Trump suggested the U.S. might be "better off" without a peace agreement. The conflict has caused significant global economic disruption, with oil prices approaching $120 per barrel and potential jet fuel shortages threatening European air travel. Meanwhile, a separate but related Lebanon ceasefire between Israel and Hezbollah remains fragile, with recent incidents straining that agreement.
