Markets Rally as U.S.–Iran Agreement Reopens Strait of Hormuz – June 15, 2026

Good morning,

An interim peace agreement between the U.S. and Iran was reached overnight, with formal signing expected this Friday. In the near term, the most significant element of the deal is the reopening of the Strait of Hormuz to unrestricted commercial shipping. “Interim” is the operative word. While the agreement restores the flow of oil through one of the world’s most important waterways, it leaves unresolved nearly every broader concern surrounding Iran’s role as a regional bad actor. Concerning is that a framework is now in place that allows both sides to defer more difficult issues beyond the current U.S. political cycle.

Markets this morning are focused on the most constructive aspect of the agreement. In premarket trading, major U.S. equity indices are higher by approximately 1.25% to 2.00%. Treasury yields are also benefiting, although not to the same extent as equities.

Oil prices and inflation expectations are unlikely to return immediately to pre-conflict levels, but a meaningful portion of the uncertainty premium can now be removed from future pricing. With that overhang diminished, investors can once again focus on the themes that have driven markets for much of the past year: resilient corporate earnings, continued AI-driven optimism, and the market’s longstanding tendency to look through geopolitical disruptions—particularly those originating in the Middle East.

Be well,
Mike
