US and Iran trade new strikes as conflict widens, rattling oil and mortgage markets

The war between the United States and Iran flared up again over the weekend of August 29-31, 2026, after six months of on-and-off fighting. U.S. forces struck Iranian rocket launchers on Larak Island, Iran fired a drone at the United Arab Emirates that was intercepted, and Iran struck U.S. bases in Jordan — a burst of escalation that sent oil prices and U.S. mortgage rates jumping and prompted President Trump to threaten to hit Iran “hard.”

What actually happened over the weekend?

According to U.S. Central Command, American forces struck two Iranian rocket launchers on Larak Island after Islamic Revolutionary Guard Corps personnel were seen preparing to fire rockets carrying sea mines into the Strait of Hormuz. Navy Capt. Tim Hawkins, a CENTCOM spokesperson, confirmed the strike, which the Associated Press noted was the first publicly acknowledged U.S. attack on Iranian positions since late July. Iran’s Revolutionary Guards said the strike killed and wounded several of its soldiers and said it retaliated with attacks on American bases in Jordan. Iran then fired a drone toward the UAE early Monday; the UAE’s Defense Ministry said it was intercepted over territorial waters and denied Iran’s claim that it had targeted the Al Minhad Air Base near Dubai.

How are the Gulf states responding?

The UAE’s Foreign Ministry called the drone strike “a blatant violation” of its sovereignty and a direct threat to its citizens, and the country said it would not hesitate to respond to further military aggression from Tehran. The UAE has already cut off all trade with Iran. Anwar Gargash, a diplomatic adviser to the UAE president, said the current “neither war nor peace” state of the region is unsustainable and argued that June’s memorandum of understanding failed to produce a workable roadmap; he called for restoring normal shipping through the Strait of Hormuz and for a broader political and economic settlement. Qatar, which has played a mediating role in the region, also condemned the strikes on the UAE and Jordan, warning that renewed active war would undercut diplomatic efforts to stabilize the region.

What did Trump say, and what’s the market fallout?

Trump warned the U.S. would strike Iran “hard” in response to the latest attacks and posted an AI-generated video Sunday depicting Iran’s Kharg Island oil export terminal — the country’s main oil hub — being “blown to smithereens.” Markets reacted quickly: Brent crude futures rose 2.5% to $90.34 a barrel and U.S. WTI crude gained 2.7% to $85.62. Analysts cited by CNBC said supply risk and depleting oil inventories are likely to persist, with strikes on refineries across the Middle East and Russia already straining global refining capacity and pushing up refined-product margins.

The oil spike fed directly into borrowing costs. The average 30-year fixed mortgage rate rose 6 basis points Monday to 6.87%, according to Mortgage News Daily — the highest level since June 2025, up 12 basis points since Thursday and more than 30 basis points over two months. Matthew Graham of Mortgage News Daily described it as a “slow grind” driven by inflation expectations, heavy bond issuance and economic resilience rather than a sudden shock. Before the war began at the end of February, the 30-year rate stood at 5.99%; for a $450,000 home with 20% down, that rate difference now adds roughly $207 to the monthly payment. Home prices are also still climbing — up 1.5% year over year in June per the S&P Cotality Case-Shiller index — a pattern analysts tied to homeowners holding onto low old mortgage rates and reluctant to sell.

What’s happening inside Iran amid the war?

Away from the battlefield, Iranian courts have handed down new death sentences tied to the January anti-government protests. Rights groups reported Monday that two women — 20-year-old Taraneh Rahimi and 43-year-old Leila Abolhasani — were sentenced to death in separate Isfahan cases, part of a broader crackdown that has already seen 29 men executed over the unrest, according to the Norway-based group Iran Human Rights. No woman has yet been executed specifically for the protests, though Iran has hanged at least 16 women this year on other charges. Rahimi was sentenced alongside nine men over a deadly incident in an Isfahan square; her sister Romina received a prison sentence. Defense lawyers said they were denied adequate access to case files. Abolhasani was convicted of arson at a store during the protests, a charge her family disputes, saying she was merely filming the scene.

Why does this matter beyond the region?

The renewed strikes underscore how a six-month-old war has moved past a narrow U.S.-Iran fight into one touching Gulf allies, global shipping lanes and now U.S. household finances. Separately, Trump is set to meet Tuesday with oil refiners and distributors — along with Interior Secretary Doug Burgum and Energy Secretary Chris Wright — to discuss boosting refining capacity, as U.S. gas prices remain above $4 a gallon despite a recent U.S.-Venezuela deal covering an estimated 65 billion barrels of oil reserves. Energy experts told CBS News that deal is unlikely to lower pump prices anytime soon.
