Trump heralds ‘perimeters’ of a deal

US President Donald Trump called off threatened strikes on Iran, saying the “perimeters of a deal” were in place, sending oil prices tumbling 5%. Iranian diplomats reacted positively to a plan presented by Qatari mediators to restore traffic through the Strait of Hormuz, which usually carries 20% of the world’s oil, The Wall Street Journal reported. But the Saudi crown prince reportedly pressed Trump to hold off signing: Gulf states now hold more sway with the president than Israel, one former Israeli intelligence official argued. Five months of oscillation between bombing and negotiation have left Trump with no good options. “He’s looking for a knockout blow when there is none,” one analyst told The New York Times.

Venezuela’s black gold rush begins

A chart showing the nations with the most proven crude oil reserves in barrels.

Foreign oil companies and investors are moving into Venezuela seven months after the US toppled then-President Nicolás Maduro, betting the world’s largest crude reserves are finally open for business. Acting President Delcy Rodríguez has scrapped the rule requiring state-run PDVSA to hold majority stakes in joint ventures, allowing private firms to operate fields directly and keep more of the profit, while Washington has unwound sanctions to ease access to Venezuela’s 300 billion barrels. But the skeptics have long memories: ExxonMobil, expelled in 2007 when its assets were expropriated, dismissed the country as “uninvestable” as recently as January. Kpler, meanwhile, cautioned that new projects will take five years and colossal sums to deliver results from an industry hollowed out by underinvestment.

Blanche scraps ‘slush fund’ plans

Acting US Attorney General Todd Blanche rescinded plans for a controversial $1.8 billion “slush fund,” smoothing his path to permanent appointment but underlining President Donald Trump’s weakening grip on his party. The Anti-Weaponization Fund would have barred tax investigations into Trump’s family and compensated allies for prosecutions. The plan faced widespread opposition and two outgoing GOP senators said they would vote against Blanche’s appointment in protest. Although Trump had threatened to keep him on in an acting capacity, the formal rescindment “establishes, beyond any doubt,” that the bill is dead. The two holdouts were regular defectors, but Trump’s relationship with his party, especially in the House of Representatives, is strained. “We are knifing each other,” one senator told CNN.

Kennedy’s U-turn on measles vaccine

A chart showing US measles cases by year.

US Health Secretary Robert F. Kennedy Jr. encouraged parents to get their children vaccinated against measles, as the worst outbreak for decades gripped the country. The 2,371 confirmed cases this year have already surpassed 2025’s total, and the two years together have cumulatively seen more infections than the rest of the 21st century combined, The Guardian noted. Kennedy, a longtime vaccine skeptic, has attempted to reduce childhood vaccination schedules and suggested the MMR vaccine could cause autism as recently as November — a claim unsupported by evidence — but shifted stance in a bad-tempered interview on CNN. “I’ve never questioned the efficacy of the MMR vaccine,” he said.

Africa’s new era of megaprojects

African nations are building major infrastructure projects at an unprecedented rate in a bid to boost energy independence and improve logistics, though commentators warn that soaring debt levels may hamper progress. The war in the Middle East, which supplies a vast amount of Africa’s fuels, exposed the continent’s reliance on energy imports, accelerating efforts to build new refineries and pipelines. Competition between China and the US for influence over the region has also brought in billions in infrastructure investment, ushering in a new era of “megaprojects.” However, rising debt payments and aid cuts are squeezing the public finances of many African countries. Though that doesn’t mean projects are “doomed,” The Economist argued, “ambition alone… will never be enough.

US carmakers speed ahead

US carmakers had a strong quarter, with Americans’ demand for gasoline-powered SUVs and trucks boosting Detroit’s profits, in contrast to European rivals. Ford, GM, and Stellantis all benefited from Washington slashing emission standards and EV promotions, plus tariffs on Chinese products protecting them from cheap EV imports. But Germany’s BMW, Mercedes-Benz, and Volkswagen all warned of lower-than-expected profits, hitting shares. The EU has stricter emissions rules, which carmakers say add to costs. They also want the bloc to strengthen defences against BYD and other Chinese EV giants, which now account for nearly 10% of the continent’s car market. Much of Asia is seeing an EV boom too, as government incentives and competition among Chinese manufacturers drive prices down.

AI giant DeepSeek’s deep cuts

Chinese AI giant DeepSeek released its latest model at a steep discount, as the country’s tech price war grows fiercer. The open-weight V4-Flash has enhanced agent capabilities — although it still trails the leading Chinese model, Moonshot’s Kimi K3. A 50% cut in token costs, and a pause on bringing in a previously announced dynamic-pricing mechanism that would have doubled costs during peak hours, suggests DeepSeek is competing for market share. Beijing, a significant investor in the company, has warned tech firms against “involution” — a race to the bottom that has already driven solar and EV prices way down. But it also subsidizes the industry’s compute and energy purchases, which experts say drives involution by keeping unprofitable companies solvent.

Hollywood quietly adopts AI

More than 10% of Hollywood job adverts are AI-related, The Los Angeles Times reported, suggesting the US movie industry is increasingly incorporating the technology despite public protests. AI use was a driver of the 2023 writers’ and actors’ strikes, and consumers are skeptical, so studios “never talk about it in public,” an industry executive told the paper. But Netflix is advertising for “Manager, Generative Workflows,” and Disney and Amazon have similar postings. Big stars including Ben Affleck and Martin Scorsese are backing AI firms: George Lucas said rejecting it was like picking a horse and buggy over a car. It is Hollywood’s “new cosmetic surgery,” The LA Times said: “Everyone knows it is happening, but few will admit to it.”

London’s first dry month in 150 years

London’s Kew Gardens, home to a weather station since 1871, recorded its first calendar month with no rain in 155 years. Europe is struggling with a continent-wide drought: Record low water levels in the Danube river have forced Hungary to shut down its only nuclear power plant, and the government is preparing for blackouts and electricity rationing at a time when the country’s economy is struggling. Romania’s Cernavodă plant, also on the Danube, has already shut down and the Rhine’s water shortage has disrupted German trade. Though London’s first-ever rain-free month is not confirmed, there is no end in sight: forecasters said there was “little sign of the widespread, sustained rainfall that would be needed” to end the UK’s drought.
