Iran's parliament security spokesman says no nuclear commitments have been made to the US, as the foreign minister confirms talks are ongoing but urges patience over premature judgements.Summary:Iran's parliamentary national security committee spokesman Ebrahim Rezaei said on Sunday that Iran has made no nuclear commitments to the United States, according to state mediaRezaei warned that the US must choose between Iranian diplomats or Iranian missiles, per state media reportsForeign Minister Abbas Araqchi told state media separately that message exchanges and talks with the US are continuingAraqchi cautioned against drawing conclusions from the process, saying outcomes cannot be judged until a clear result is reached, per state mediaThe foreign minister advised against giving weight to speculation circulating around the talksIran's government sent a fractured diplomatic signal on Sunday, with a senior parliamentary official flatly denying any nuclear commitments to Washington while the country's foreign minister insisted that dialogue with the United States remained very much alive.Ebrahim Rezaei, spokesman for Iran's parliamentary national security committee, said in blunt terms that Tehran had made no nuclear pledges to the US side, and framed the choice before Washington in stark terms: engage Iranian diplomats, or face Iranian missiles. The remarks stand as the most direct parliamentary pushback yet against speculation that this week's tentative ceasefire extension framework had set the stage for rapid progress on the nuclear file.Foreign Minister Abbas Araqchi offered a more measured tone in separate comments to state media, confirming that message exchanges and talks with the United States were continuing. He urged against reading too much into the current state of the process, saying neither optimism nor pessimism was warranted until a concrete outcome emerged, and dismissed circulating speculation as a distraction from the substance of the negotiations.The divergence between the two statements reflects an internal tension that has run through Iranian diplomacy since the February conflict began. Hardliners in parliament have consistently framed any nuclear concession as a capitulation, while the foreign ministry has sought to project controlled engagement without foreclosing a deal.The backdrop to Sunday's remarks is a tentative agreement, reported late last week, under which US and Iranian negotiators drafted a memorandum of understanding that would reopen the Strait of Hormuz, lift the US blockade on Iranian ports, and launch a 60-day structured negotiation on Tehran's nuclear program, including the fate of its stockpile of highly enriched uranium. Neither US President Donald Trump nor Iran's supreme leader had publicly endorsed the document as of Sunday, and both sides described it as a work in progress.The nuclear question has been the central sticking point throughout the post-conflict diplomacy. Washington has insisted Iran give up its enriched uranium stockpile without receiving sanctions relief in return, a position Tehran has resisted since direct talks opened in Muscat in February. Iran has equally rejected any framework that does not address the ongoing US blockade and the lifting of economic sanctions as part of a first-phase settlement.For oil markets, the risk premium built into crude since the Strait of Hormuz was effectively closed in late February has shown little sign of unwinding. Distillate inventories have fallen to multi-decade lows and shipping costs remain elevated as long as both blockades remain in place. Sunday's parliamentary comments are unlikely to help. Until Tehran's supreme leadership and Washington's presidency align behind a common text, the strait stays contested and the supply disruption continues to set the floor beneath global energy prices.---The hardline parliamentary statement pushes back directly against any market optimism generated by Thursday's tentative ceasefire extension framework, which had lifted hopes for a rapid resolution to the Strait of Hormuz standoff. Oil prices remain sensitive to any signal that nuclear talks could collapse or stall, given that neither side has lifted its blockade and the strait remains constrained. The foreign minister's call to avoid judging the process prematurely will do little to ease uncertainty among energy traders watching for a breakthrough that would ease supply restrictions. Until both supreme-leader and presidential sign-off materialise on the US side, and Tehran delivers a concrete counter-position on enriched uranium, the risk premium baked into crude is unlikely to unwind in any meaningful way.
