The US-Iran nuclear deal enters a 60-day implementation phase with Hormuz reopening in focus. Oil-linked currencies face headwinds as crude supply risk fades. Here is the setup to track.
Trump said the Iran deal should be successful and confirmed the text of a memorandum of understanding is finalized, awaiting a formal signing ceremony in Geneva. The agreement pushes the nuclear file into a second stage focused on verification and sanctions relief. Technical details on uranium stockpiles, enrichment limits, and inspection mechanisms remain unresolved and are expected to dominate the next 60 days of talks.
For markets, the headline is the expected reopening of the Strait of Hormuz. Normal traffic could resume in the coming months. That shift undercuts the oil risk premium that has supported crude prices and, by extension, oil-linked currencies. The Canadian dollar and Norwegian krone, which have drawn support from elevated supply fears, could give back some of those gains. A softer crude outlook also removes a tailwind for the ruble, though sanctions dynamics complicate that relationship.
Trump reiterated that Iran will never have a nuclear weapon and warned that Iran would "suffer" if it attempts to pursue one. He also pushed back against speculation about upfront US financial transfers. Economic relief would be conditional and performance-based. That language limits the upside for Iran-linked narratives but does not change the near-term oil trajectory.
The deal is structured in phases. Trump described the current framework as the beginning of an implementation period, not the end of negotiations. The second phase, which starts after the Geneva signing, focuses on verification, sanctions relief sequencing, and the future of Iran's nuclear infrastructure. The timeline to Hormuz reopening will depend on how quickly those details are settled.
For forex traders, the key variable is not the diplomatic text but the speed of the strait's return to normal traffic. A faster resumption is broadly bearish for crude and CAD. Any delay or collapse of the technical talks would reverse that trade, restoring the supply risk that has supported energy currencies. The signing ceremony in Geneva has no confirmed date yet.
