US and Iran escalate Hormuz attacks as Trump's ultimatum passes

Iran Peace Deal Analysis for September 10, 2026

Iran and the US have shifted from ceasefire talks to direct military strikes on shipping in the Strait of Hormuz. Trump's 48-hour ultimatum expired on September 9 with no breakthrough. Instead, tanker attacks intensified. Both countries are now hitting each other's vessels in what Reuters calls the biggest wave of attacks on shipping since the war began. Oil prices jumped above $100 per barrel.

The ceasefire that existed since mid-August has ended. The two-week pause was meant to give negotiators space to revive a deal, but talks stalled almost immediately. By late August, Trump was already threatening a crushing economic operation on Iran and refusing to extend the temporary pause. Iran's diplomatic push to reopen the Strait of Hormuz went nowhere. The US energy secretary said the nuclear agreement may not happen anytime soon. Any remaining diplomatic channel closed.

Trump is framing the war as an election issue, claiming it will end after the midterms. He has threatened to bomb Oman if it interferes. Israeli leaders are pushing hard against any deal. Senate Armed Services Committee leadership opposes compromise with Iran. Tehran has warned of a recalibrated military posture and continues striking US targets. With active hostilities now the norm and both sides entrenched, a ceasefire in the next 30 days would require a shock reversal that the current pattern does not support. The most likely scenario is continued tit-for-tat Hormuz attacks until the US election passes.
