What are the latest developments in the escalating US-Iran conflict, including President Trump's vow to hit Iran's economy hard, the Treasury Department's promise of unprecedented sanctions to be announced next week as a "one-two punch" combining financial isolation and the naval

Here is a concise rundown of the latest developments across all the fronts you asked about, based on evidence from the past several days.

US Economic Pressure: Sanctions and Blockade

• Trump's shift back to economic warfare. The administration is signaling a pivot from months of bombing to a strategy of squeezing Iran's economy until it capitulates on reopening the Strait of Hormuz and ending its nuclear program . Trump has also demanded compensation from Iran as a new condition for talks .
• Naval blockade to be sustained "indefinitely." The US announced on August 13 that it can maintain its naval blockade of Iran indefinitely and will continue ratcheting up economic pressure . The American military has been redirecting commercial vessels away from Iranian ports under the blockade .
• "One-two punch" of sanctions. The administration is preparing a new wave of unprecedented Treasury sanctions to be announced next week, intended to combine financial isolation with the existing naval blockade. (This specific framing appears widely in reporting, though the exact Treasury announcement date is embedded in the broader policy shift described above.)

Strait of Hormuz: Attacks and Shipping Standstill

• 15+ ADNOC tankers attacked. Abu Dhabi National Oil Company confirmed that 15 of its vessels have been hit by missiles and drones since the conflict began, with three struck in a single week in early August . Additional attacks on August 13–14 brought the total to at least 16 .
• Shipping nearly at a halt. Transit through the Strait of Hormuz has ground to a near standstill — on August 14, only about 6–8 ships crossed, compared with a pre-conflict daily average of 17–20 . Shipping data showed traffic dropping to as few as 6 vessels on some days .
• UAE condemnation. The UAE has repeatedly blamed Iran for the strikes, calling them "acts of piracy." On August 14, the UAE said Iran fired drones at two tankers in the strait . On August 8, it condemned a missile attack on an ADNOC vessel as a "flagrant violation" .

Stalled Diplomacy and the June Interim Deal

• June deal has unraveled. The 14-point Islamabad Memorandum of Understanding signed in June declared an end to hostilities, but both sides now accuse each other of violating its terms . The US says Iran failed to reopen the strait; Iran says the US maintained the blockade and sanctions .
• No progress on reviving talks. Iran's Foreign Minister Abbas Araqchi said on August 9 there are no direct US-Iran talks and Tehran will not resume them until Washington addresses alleged violations of the June deal . A senior Iranian source confirmed on August 12 there has been "no progress" in efforts to revive the interim agreement .
• Iran's conditions for reopening the strait. Tehran has issued sweeping demands: lifting the US naval blockade and sanctions, withdrawal of US military forces from the region, and compensation . Iran says it is near a separate deal with Oman on alternative shipping lanes, but that alone would not be enough to reopen the waterway .
• Trump claims "total control" over the strait. Trump posted on social media that the US has "total control" of the Strait of Hormuz — a claim Iran angrily denies, insisting the strait remains blocked .
• European and Qatari mediation. Messages are being exchanged via intermediaries, including Qatar and Oman . Qatar's Foreign Ministry said in early August that drafts of a potential agreement are "being circulated," but no direct talks are happening .

Senate-Passed Russia-Iran Sanctions Bill

• The Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 passed the Senate on August 7 by a vote of 86–11 . It includes expanded sanctions on Iran alongside penalties on buyers of Russian oil and gas .
• House action still pending. The message on Senate action was sent to the House on August 10 , where the bill awaits consideration. However, controversial tariff provisions — allowing Trump to impose steep tariffs on countries purchasing Russian oil — have drawn opposition from Democrats, some Republicans, and industry groups, risking a stall in the House .

Key Open Questions

• The specific timing and exact scope of the Treasury's "next week" sanctions announcement could not be independently confirmed down to the day from current sources.
• The role of European interlocutors beyond the Qatari and Omani mediation channels is mentioned in reporting but not detailed in the sources available.
