North America Brief: US Navy Seizes Iranian Ship — Trump Says Marines Blew Hole in Engine Room
USS Spruance intercepts Iranian-flagged Touska in Gulf of Oman. Trump says Marines took custody after Navy disabled ship's engine. Oil rebounds 4-6%. Iran vows retaliation. Iran says "no plans" for talks. Islamabad talks hang by thread. Ceasefire expires in 3 days.
Day 52. The blockade stopped being theoretical. The USS Spruance intercepted the Iranian-flagged Touska in the Gulf of Oman on Sunday. Trump said the Navy warned the ship to stop, the crew refused, so the Navy "blew a hole in the engineroom." US Marines boarded and took custody. Iran vowed retaliation. Oil jumped back above $94. And Iran said it has "no plans" for new talks — throwing Monday's scheduled Islamabad round into serious doubt.

The Touska seizure
Trump announced on Truth Social that the USS Spruance — a guided missile destroyer — intercepted the Iran-flagged container ship Touska in the Gulf of Oman. "We gave them fair warning to stop. The Iranian crew refused to listen, so our Navy ship stopped them right in their tracks by blowing a hole in the engineroom. Right now, US Marines have custody of the vessel." This is the first ship seized since the blockade began on April 13. Tracking data showed the Touska last broadcast its position about 30 miles off Iran's coast. The US framing: enforcement of the blockade. Iran's framing: an act of war.
Iran vows retaliation
Iran responded with what CNN described as vows of "swift response." State media reported Iran would have "no plans to participate" in new talks after the US seized Iran-flagged vessels. Iranian negotiators told Al-Monitor that no negotiations would take place unless the US ended its blockade. The seizure has effectively created two simultaneous ultimatums: Trump's "deal by April 22 or fighting resumes" and Iran's "end blockade or no talks." The overlap is almost zero.
Oil's whiplash continues
Oil jumped 4-6% on the seizure news. Brent rose to the mid-$90s. US crude futures surged past $87. This caps a brutal week of volatility: $99 Thursday, $90 Friday after Iran opened Hormuz, mid-$90s Saturday after Iran closed it again, and back up Sunday after the US seized the Touska. Bloomberg's analysis suggested some government officials and Wall Street analysts are now considering a scenario where oil surges to $200/barrel if Hormuz stays closed. The physical crude market remains frozen.
Monday talks in question
Despite Iran's "no plans" statement, US negotiators are still expected to head to Islamabad on Monday. Vance is expected to lead the delegation. Pakistan's mediators are working overtime. Egyptian Foreign Minister Badr publicly expressed optimism the ceasefire could be extended. Privately, diplomats are less sanguine. One senior administration official told CNN that Vance's experience brokering the Lebanon ceasefire gives him credibility heading into Islamabad — but also noted the "trust deficit" is now wider than before.
The market's bet
Despite the escalation, Wall Street's response was measured. Stocks gave back some of Friday's record gains but didn't crash. The S&P 500 remains near record highs. Investors are betting that even with the seizure and the Hormuz reclosure, a deal is more likely than a full-scale war. That bet could prove right or wrong in the next 72 hours.
What to watch
Whether Monday's Islamabad talks actually happen. Iran's retaliation for the Touska seizure. The ceasefire expires Wednesday, April 22. Trump's willingness to extend or walk away. Oil's next move — if Hormuz stays closed through the week, the $100+ scenario returns. And the Israel-Lebanon ceasefire, holding through day 4.
