Wall Street, global markets surge after US-Iran ceasefire sends oil prices below $100 a barrel

Wall Street surged in Wednesday premarket trading as oil prices plunged below $100 after the U.S. and Iran agreed to a two-week ceasefire that includes the reopening of the Strait of Hormuz. Futures for the S&P 500 jumped 2.7% before the opening bell and futures for the Dow Jones Industrial Average climbed 2.6%. Nasdaq futures soared 3.4%. Benchmark U.S. crude sank $18.43 to $94.52 a barrel, a nearly 16% decline. Brent crude, the international standard dropped $15.54 to $93.73 a barrel. Natural gas futures declined close to 5%. The drops reversed some of the rise in oil prices since the start of the war more than five weeks ago that had effectively blocked passage through the strait that 's a crucial route for global supplies. For now, market analysts see the ceasefire as more of a reprieve than a resolution. "Yet the mood remains one of cautious optimism rather than outright celebration," said Tim Waterer, chief market analyst at KCM Trade. "The ceasefire is only two weeks long, and markets will be watching closely to see whether shipping through the Strait of Hormuz normalizes as promised and whether the fragile truce can pave the way for a more durable peace agreement." Late Tuesday, Trump said he was holding off on his threatened attacks on Iranian bridges, power plants and other civilian targets. Iran 's foreign minister said passage through the strait would be allowed for the next two weeks under Iranian military management. But analysts warned against too much optimism. Airline stocks soar U.S. Treasury yields fell as the drop in oil prices could alleviate some of the concerns in the bond market about a hefty spike in inflation. The yield on the 10-year Treasury fell to 4.24% from 4.30% on Tuesday. In equities trading, major U.S. airline stocks soared on the steep drop in oil prices. Delta and United jumped more than 12% in premarket while American rose 10%. Delta on Wednesday also reported first-quarter sales and profit that came in ahead of Wall Street forecasts and said that demand remained strong with the summer travel season just a few months away. Companies in the energy sector fell along with the drop in oil prices. Exxon Mobil and ConocoPhillips each lost close to 6% while Chevron tumbled 4.6%. Elsewhere, in Europe France 's CAC 40 added 4.5% by midday, while the German DAX soared nearly 5%. Britain 's FTSE 100 gained 2.9%. In Asia, Japan 's benchmark Nikkei 225 gained 5.4% to finish at 56,308.42. Australia 's S&P/ASX 200 jumped 2.6% to 8,951.80. South Korea 's Kospi soared 6.9% to 5,872.34. Hong Kong 's Hang Seng surged 3.1% to 25,893.02, while the Shanghai Composite added 2.7% to 3,995.00. In currency trading, the U.S. dollar fell to 158.39 Japanese yen from 159.52 yen Wednesday. The euro cost $1.1701, up from $1.1597. The dollar usually becomes a safe haven during geopolitical uncertainty, so the ceasefire deal worked to lessen that appeal.
