Iran has publicly rejected a proposed ceasefire agreement with the United States, shattering expectations that a deal could be signed as early as Tuesday.
The rejection comes after US officials and Pakistani mediators indicated that a framework for ending the ongoing conflict was ready for signature, creating a sharp diplomatic reversal just hours before the anticipated announcement.
The sudden setback introduces fresh volatility into the region's energy outlook.
With military strikes already confirmed by US Central Command against targets in southern Iran, the collapse of the immediate diplomatic window raises the risk of prolonged hostilities.
Investors are now reassessing the probability of a near-term de-escalation, a key driver for crude and shipping risk premiums.
The breakdown of the US-Pakistan mediated talks has prompted an immediate pivot to alternative channels.
