Ceasefire: Markets Cheer, Risk Lingers
A last‑minute U.S.–Iran ceasefire sent oil and stocks lower and higher respectively, but the calm looks fragile rather than settled. Markets pared the war risk premium—Brent and WTI fell and equities jumped—after President Trump signalled a conditional pause in strikes, yet immediate questions remain about Strait of Hormuz operations and fresh strikes in Lebanon. That matters because shipping and insurance costs can re‑spike even if headlines calm, and Tehran is already hinting at transit fees that would politicise a key trade chokepoint.

Wall Street treated a two-week U.S.-Iran ceasefire like a fire alarm that suddenly stopped ringing. On April 8, oil plunged below $100 a barrel and U.S. stocks jumped after President Donald Trump said he would pause further strikes if Iran reopened the Strait of Hormuz. (cnbc.com) That reaction made sense because traders had spent days pricing in a worst-case shock: a blocked waterway, fewer tankers, and more expensive fuel. The U.S. Energy Information Administration says about 20.9 million barrels a day moved through the Strait of Hormuz in the first half of 2025, equal to about 20% of global petroleum liquids consumption. (eia.gov) The strait is not just an oil story. The Energy Information Administration says about 20% of global liquefied natural gas trade also passed through Hormuz in 2024, mostly from Qatar, so a disruption hits power markets as well as gasoline and diesel. (eia.gov) The ceasefire itself is narrow and temporary. Multiple outlets reported that Washington and Tehran agreed to a two-week pause, with Pakistan helping mediate, and the White House said the deal was tied to reopening the strait. (whitehouse.gov) (cbsnews.com) That is why the relief rally faded almost as soon as it began. By April 9, oil was climbing again and global shares were giving back gains as investors focused on whether ships were actually moving and whether the fighting was really contained. (washingtonpost.com) (nytimes.com) The shipping picture is the part markets cannot solve with one headline. The New York Times reported on April 9 that ship traffic through the strait had dropped further even after the ceasefire, because crews and insurers were still wary of hugging Iran’s coast. (nytimes.com) Insurance is where a shaky truce turns into real costs. Even if missiles stop for a few days, war-risk premiums for tankers can stay high, and those extra charges get folded into the delivered price of oil the way surge pricing gets folded into a late-night cab fare. (nytimes.com) (cfr.org) Tehran also appears to be testing how much control it can keep without fully shutting the route. CNBC reported on April 8 that Iran was planning to demand tolls in cryptocurrency from shipping firms, while the White House said Trump wanted the strait open “without limitation, including tolls.” (cnbc.com) At the same time, the war’s edges were still on fire. On April 9, The Associated Press reported heavy Israeli strikes in Beirut that killed at least 182 people, after Israel said the Iran truce did not apply to Lebanon. (apnews.com) That leaves markets in an awkward middle ground: the first panic is gone, but the old supply map has not been restored. A ceasefire can erase part of the war premium in a day, but tanker traffic, insurance rates, and the risk of a new strike usually take longer to calm than a stock chart does. (cnbc.com) (apnews.com)
