A potential breakthrough in US-Iran negotiations sent oil prices tumbling after 33 commercial ships transited the Strait of Hormuz on Sunday, raising hopes for a deal that could unwind the conflict that has gripped the Middle East.
"The straits have to be immediately reopened, and then we will enter, under agreed-to parameters, into very serious talks about enrichment, about the highly enriched uranium and about their pledge to never have nuclear weapons," US Secretary of State Marco Rubio said.
The market reaction was immediate. Brent crude, the international benchmark, fell more than 4 percent to its lowest in over two weeks, while West Texas Intermediate crude dropped over 5 percent. The improved risk sentiment lifted Nasdaq 100 futures by 1 percent and S&P 500 futures by 0.62 percent. Spot gold also rose 1.3 percent.
The core of the potential agreement is a memorandum of understanding that would establish a 60-day framework to negotiate a final settlement, according to US officials. Under the preliminary terms, Iran would agree to surrender its stockpile of highly enriched uranium and commit to not developing nuclear weapons. In exchange, the blockades on the vital waterway would be lifted, restoring a critical artery for global energy supplies.
Sticking Points Remain
Despite the positive market reaction, significant hurdles could still derail the process. Iranian state media reported that disagreements persist over key clauses, particularly Tehran's demand for the immediate release of some of its $25 billion in frozen assets as a precondition. The US, however, wants to link the release of funds to a final, comprehensive nuclear agreement.
"Without the release of a specific portion of Iran’s blocked assets in this very first step... there will be no agreement," an informed source told Iran's Tasnim news agency.
US President Donald Trump, after saying a deal was "basically done" on Saturday, adopted a more cautious tone on Sunday. "The negotiations are proceeding in an orderly and constructive manner, and I have informed my representatives not to rush into a deal," he posted on social media, adding that the US blockade of Iranian ports will remain in "full force and effect until an agreement is reached, certified, and signed."
Regional Complications
The scope of the ceasefire also remains a point of contention. Iran and its ally Hezbollah insist that any deal must end hostilities on all fronts, including the ongoing conflict between Israel and Hezbollah in Lebanon. However, an Israeli official told CNN that Prime Minister Benjamin Netanyahu secured Trump's support for Israel to "maintain freedom of action against threats on all fronts."
While the passage of 33 oil tankers, container ships, and other vessels signals a tangible de-escalation, analysts caution that volatility may persist. "Despite any reopening of the Strait of Hormuz being a positive for global oil flows, the fluid nature of negotiations and the remaining points of disagreement suggest oil price volatility is likely to remain for some time," ANZ bank strategists said in a client note.
