Iran has ruled out direct talks with US officials, even as Foreign Minister Abbas Araghchi travels to Pakistan — a trip that had briefly raised speculation about back-channel diplomacy between the two countries.

The announcement came shortly after Araghchi landed in Islamabad, with Tehran making clear the visit carries no diplomatic overture toward Washington. The timing and bluntness of the statement appear designed to shut down any expectation that Pakistan could serve as an intermediary for US-Iran contact.

Oil Waivers Add Pressure

Separately, the US has signaled it will not renew oil sanctions waivers for Iran or Russia. These waivers had previously allowed certain countries to buy Iranian and Russian crude without triggering US penalties. Letting them lapse tightens the financial squeeze on both nations and removes flexibility for buyers in Asia and elsewhere who had been operating under those exemptions.

For oil markets, the end of waivers matters at the margin. Buyers who relied on cheaper Iranian or Russian barrels will need to source elsewhere, which could nudge prices upward depending on how quickly alternative supply fills the gap. India, which has been a significant buyer of discounted Russian crude, is among the countries that may need to recalibrate its import mix.

What the Diplomatic Freeze Means

The refusal of direct talks keeps the US-Iran relationship in a state of managed hostility. Without a negotiating channel, disputes over Iran's nuclear program, regional proxy activity, and sanctions enforcement have no formal outlet. That raises the baseline risk of miscalculation, particularly given ongoing tensions involving Israel.

Pakistan's role here is worth watching. Islamabad has historically tried to maintain working relationships with both Tehran and Washington. Araghchi's visit likely focuses on bilateral trade and regional security — but the optics of a senior Iranian diplomat traveling to a US-aligned country always carry diplomatic weight.

For now, the key signals to track are whether the US follows through on the waiver non-renewal with enforcement action, and whether any indirect diplomatic contact between Washington and Tehran emerges through third parties in the weeks ahead.
