Source: TradingView Why US-Iran Ceasefire Hopes Lifted Stocks and Cooled Oil The offer went to Tehran on Monday, Reuters reported. It aims to revive the Islamabad Memorandum, the peace deal Pakistan and Qatar brokered in June. Donald Trump and Iranian President Masoud Pezeshkian signed it remotely on June 17. The truce collapsed in July when strikes resumed. Stocks jumped on the news. The SP 500 rose 0.63% and the Nasdaq climbed 1.02%, market data shows, with analysts estimating the total gain at roughly $550 billion, with tech stocks leading. $550 BILLION has been added to US stocks today as markets price in signs that US-Iran Peace talks could resume. US stocks have a track record here. They proved the strongest wartime hedge in the wars first phase, beating gold and Bitcoin (BTC). Still, Mondays rally came as US Central Command announced a ninth straight night of strikes. CENTCOM began conducting a new wave of strikes against Iran at 7 p.m. ET today for the ninth consecutive night. The strikes will continue degrading Iranian military capabilities used to attack commercial vessels and civilian mariners transiting the Strait of Hormuz. Oil moved the other way. WTI traded near $82.65 and Brent slipped to about $88.46, TradingView data shows. This is only hours after oil price topped $90 after reports of escalating war on Sunday. Tehran Doubts and Houthi Threats Keep the Rally Fragile Iran is not sold. Parliament Speaker Mohammad Bagher Ghalibaf said the US keeps sending military equipment to the region while claiming it wants peace. Weve reached the stage of mastery in recognizing these American games, and on that basis, weve prepared ourselves. Actions must confirm claims, not contradict them, Ghalibaf said. His post came hours after Yemens Houthis declared a maritime embargo on Saudi shipping through the Bab el-Mandeb Strait. Military spokesman Yahya Saree called it an eye for an eye response to Riyadhs siege of Houthi ports. That threat hits Saudi Arabia where it hurts. Riyadh now sends over 70% of its crude exports through the Red Sea port of Yanbu, Kpler data shows. Those flows run near 4 million barrels per day. The pivot began while Hormuz disruptions threatened cheaper US gasoline. The safety net is thin too. The US Strategic Petroleum Reserve sits at its lowest level since 1983 after a record 400 million-barrel release in March. Traders already price high odds of $4 gas by the end of July. Such a move would constitute a climb of nearly 25% above current levels. Gasoline Price Performance. Source: TradingView Markets have seen this pattern before. A June relief rally faded once strikes resumed. Meanwhile, a fresh oil spike could revive pressure for Fed hikes. For now, the gains rest on a proposal, not a pause. Real progress will decide whether they last.
