US stocks rally, oil plunges on Iran deal, June 15, 2026
June 15, 2026
Markets start the week leaning into risk. A peace framework between Washington and Tehran would reopen the Strait of Hormuz, shut for more than a hundred days. Oil is collapsing to a three-month low while US index futures point to a sharply higher open. The real arbiter of the week remains the Fed decision on Wednesday.
Oil erases its war premium
Crude is falling hard. WTI loses about 4.7% near $81 a barrel and Brent drops close to 4% toward $84, its lowest level in three months. The trigger is a single announcement: the United States and Iran reached a framework deal over the weekend to reopen the Strait of Hormuz. A memorandum is due to be signed Friday in Switzerland, ahead of a 60-day ceasefire. The market is unwinding the risk premium built up since spring, when Brent topped $114 in March. For Billy Leung, strategist at Global X ETFs, the immediate effect is a repricing of the inflation risk premium that investors had carried since the strait closed.
Stocks push higher again
Relief is spreading across markets. On Friday, Wall Street had already closed green, the S&P 500 at 7,431 (+0.5%), the Nasdaq at 25,889 (+0.31%) and the Dow Jones at 51,202 (+0.7%). This Monday, futures extend the move: the Nasdaq 100 gains about 2.1% and the S&P 500 nearly 1.2% before the open. Asia set the tone overnight, with the Nikkei up 5.5% and the Kospi 5.7%. SpaceX, which went public on Friday, adds to the momentum with a premarket gain of more than 5% on its second day.
Weaker dollar, lower yields
The return of risk appetite weighs on safe havens. The dollar index sheds 0.32% to 99.48 and the euro holds above 1.1600, around 1.1610. In bonds, the US 10-year yield falls five basis points, to 4.42%. In crypto, bitcoin gains 2% toward $66,150, its highest since early June.
Caution still warranted
The enthusiasm should not hide the unknowns. Charu Chanana, chief investment strategist at Saxo, warns that this is a framework rather than a final deal, and that the real test will be Friday's signing. On top of that comes the Fed meeting on Wednesday, where a hold is widely expected but the chair's tone will matter as much as the decision.

The bottom line
The market is unwinding its war premium: oil sharply lower, stocks higher, dollar weaker. Until Friday's signing and Wednesday's Fed decision are settled, caution still applies. For these levels every morning, see our market brief.
