A formal signing ceremony in Switzerland and the promised reopening of the Strait of Hormuz have injected cautious optimism into global markets, but analysts warn that sentiment is not the same as supply.
After months of an escalate-then-retreat loop, the United States and Iran announced a peace agreement over the weekend.
A formal signing is scheduled in Switzerland and, critically for energy markets, the deal includes the toll-free reopening of the Strait of Hormuz and the removal of the US naval blockade.
Caution remains warranted, however, until any agreement is formally signed. Lebanon remains a persistent flashpoint, while potential sequencing disputes between Washington and Tehran could still slow implementation.
Iran’s nuclear commitments have also been pushed into a 60-day negotiating window, underscoring that key details remain unresolved even as momentum builds.
Still, the structural constraints that have repeatedly derailed earlier de-escalation efforts appear, at least for now, to be temporarily aligned.
Claudio Galimberti, Chief Economist at Rystad Energy, offered a measured assessment from his base in Houston, Texas.
“This deal, if it holds, is the most workable outcome available to all parties at the table, which gives it a degree of credibility,” said Galimberti.
“Washington has an incentive to avoid a spike in gasoline prices ahead of the midterms, while Tehran is seeking sanctions relief and restored export revenues, and the global economy has a strong interest in keeping the Strait of Hormuz open.
“On rare occasions, these incentives align in a coherent way, and that is the strongest argument that this is more than another short-lived diplomatic cycle.”
Galimberti cautioned that a signed deal and a functioning one are two different things, adding that the sequencing standoff (with each side demanding the other act first) remains the central point of failure, and Lebanon continues to inject unpredictability that neither capital can fully manage.
He also noted that markets have been here before: an initial rally on the headline, then a gradual retreat as the difficulty of implementation becomes clear, a pattern he sees little reason to expect will be different this time.
“What can be said with some confidence is that a credible reopening of the Strait of Hormuz would be one of the most important developments for the global economy at this juncture, particularly given that US headline Consumer Price Index (CPI) is above 4 per cent for the first time since 2023, real wages are declining for a second consecutive month, and the ECB is still tightening policy into an energy shock, leaving the system with limited capacity to absorb further supply disruption,” said Galimberti.
“In that context, every barrel previously constrained through the Strait represents inflationary pressure that would begin to unwind, at least at the margin.”
Galimberti also tempered expectations around the pace of market recovery, arguing that even a successful signing would not translate quickly into normalised conditions.
While Friday’s close reflected a genuine improvement in sentiment, he noted that sentiment and physical supply are not the same thing.
Production ramp-ups take time, logistics need to be rebuilt, and the risk premium baked into crude prices will not evaporate overnight, particularly since the UAE’s departure from OPEC+ represents a structural shift that no diplomatic handshake reverses.
For Galimberti, a deal that holds would be meaningful progress, but progress toward a destination rather than arrival at one.
The announcement lands against a troubling inflation picture across major economies.
US headline CPI accelerated to 4.2 per cent year-over-year in May, the first reading above 4 per cent since 2023, with inflationary pressure concentrated in gasoline and limited core spillover so far.
Real wages fell for a second consecutive month, though the June University of Michigan consumer sentiment survey rebounded from its record low, supported by stabilising gasoline prices and easing labour market concerns.
The European Central Bank last week raised rates by 25 basis points to 2.25 per cent, unanimously and explicitly in response to the energy shock stemming from the conflict.
It now projects inflation averaging 3.0 per cent in 2026 before easing to 2.3 per cent in 2027, while GDP growth is expected at just 0.8 per cent this year.
China’s producer prices accelerated to 3.9 per cent year-over-year while consumer inflation held at 1.2 per cent, reflecting weak domestic demand and margin compression rather than a broad-based price shock.
Whether the signing in Switzerland changes any of those figures will depend entirely on what happens after the cameras leave.
