A War Abroad Arrives at the Pump, and the Fed Takes Notice

Escalation in the Gulf, Costs at Home

The defining thread of the week ran from the Strait of Hormuz to American checkout lines. On Thursday, Iran and the United States exchanged the largest wave of attacks on shipping since their war began, striking military, shipping and energy targets and shattering a month of relative calm. An estimated 20 Iranian ballistic missiles hit Muwaffaq Salti Air Base in Jordan, damaging multiple U.S. fighter jets in a direct strike on American military assets. The same day, the International Atomic Energy Agency board referred Iran to the UN Security Council for the first time in 20 years, citing Tehran's failure to cooperate with an investigation into uranium traces detected by inspectors.

The economic consequences did not wait. On Friday, the national average price of diesel crossed $6 a gallon for the first time in history, according to AAA data. Diesel moves nearly every good in the U.S. economy, from freight trucking to agriculture, and economists tied the record to the war's disruption of global oil flows. Crude moved the other way Friday, dipping below $100 a barrel on reports of planned Gulf diplomatic talks, but energy markets remained volatile as the Hormuz disruption dragged on.

The pressure showed up in the government's inflation data. August's Consumer Price Index, released Friday, put annual inflation at 3.4%, a reading economists attributed largely to elevated energy costs tied to the war. The hot print pushed up market bets that the Federal Reserve will raise interest rates when policymakers meet next week. According to The Hill, a hike has become increasingly likely, and MarketWatch reported markets are bracing for a possible series of increases, as many as three.

Diplomacy Falters on Two Fronts

The week also delivered setbacks to two American diplomatic efforts. In Ukraine, Russia struck Kyiv with ballistic missiles early Tuesday, ending a three-day ceasefire hours after U.S. peace negotiators departed the country. The strikes killed two people and injured others. The 72-hour pause had allowed visits by U.S. envoys Steve Witkoff and Jared Kushner, who cited substantive progress in negotiations before leaving. Ukrainian President Volodymyr Zelensky told Axios the U.S. is exploring whether Ukraine and Russia could take de-escalation steps this winter alongside restarted talks toward a broader peace agreement.

Closer to home, Canada's retaliatory tariffs on roughly $20 billion of American goods took effect at 12:01 a.m. Tuesday, striking back at President Donald Trump's trade measures. Duties on U.S. steel and aluminum products doubled to 50%, and Trump threatened to block sales of Canadian manufacturer Bombardier's jets in the U.S. CNBC valued the full retaliatory package at $27.6 billion. At stake is the world's largest bilateral trading relationship, and NPR reported the new duties will likely hit exporters and consumers on both sides of the border as Canadian officials brace for a prolonged trade war.

Politics, Violence and a Deadly Crash

At home, the week opened with two jolts. An Amazon-branded Boeing 767 cargo plane overran the runway at Miami International Airport on Sunday, striking vehicles on the ground and catching fire. The crash killed five people and injured five others, officials said, and federal investigators on Monday detailed plans for probing why the jet failed to stop.

The same day, an armed man lunged at Amy Acton, Ohio's Democratic candidate for governor, at the Canfield Fair near Youngstown. Police said the man carried a pistol and knocked over fairgoers while forcing his way toward the candidate; her campaign said several attendees were injured. The attack added to national concerns about political violence with Ohio voters heading to the polls in roughly two months.

That backdrop framed an unprecedented political event: Republicans opened the first midterm party convention in U.S. history Wednesday in Dallas, with Trump headlining. Party officials aim to energize low-propensity MAGA voters ahead of races where Republicans are defending majorities in both chambers of Congress, while USA Today reported Democrats have improved their odds of retaking both. Elsewhere on the political calendar, Rep. Chris Pappas and former Sen. John E. Sununu set a New Hampshire Senate matchup that ranks among the GOP's top pickup opportunities, and the Trump administration asked the Supreme Court to enforce postal restrictions on mail ballots as North Carolina ballots enter the mail.

AI Rivals Align, and the Week Ahead

The week closed with an unusual show of unity among competitors. Anthropic CEO Dario Amodei on Saturday called for an immediate, industry-wide slowdown in AI development, warning the current pace could bring devastating consequences within months. Elon Musk backed the call, and OpenAI CEO Sam Altman signaled agreement, confirming OpenAI will not go public this year and calling an IPO ill-advised over safety concerns. Amodei also laid out a three-step plan to pace the frontier, including granting outside evaluators access to Anthropic's models. The joint stance capped a week of warnings, including a senior Anthropic safety researcher who put the odds that AI could kill all humans above 10% by decade's end.

The week also carried a solemn milestone. Memorial ceremonies were set for Friday in New York, Virginia and Pennsylvania to mark 25 years since the Sept. 11 attacks, which killed nearly 3,000 people. The 9/11 Memorial and Museum unveiled a new exhibition aimed at the generation born after the attacks, and newly released documents showed New York City officials knew within weeks of the towers' collapse how dangerous the air around ground zero was, records that stayed under wraps for years.

Next week opens with lighter fare. The NFL's first full Sunday slate of the 2026 season kicks off across the league, days after the 49ers beat the Rams 27-7 before more than 100,000 fans in the league's first regular-season game in Australia. And in New York, Ben Shelton, fresh off a 3:33 a.m. five-set upset of Carlos Alcaraz, faces No. 1 Alexander Zverev in the U.S. Open men's final.
