US, Iran launch new strikes

The US and Iran traded fresh attacks, further undermining a protracted ceasefire and dampening hopes of the two sides reaching a durable peace deal. The American strikes were the second set this week of what Washington has characterized as defensive actions, with the most recent ones hitting Iranian drones and a launch site. Tehran said it targeted a US air base in the region; Kuwait, which is home to one such facility, said it had deployed air defenses against missile and drone threats. The ongoing pattern of negotiations interrupted by warnings and strikes points to the balance of leverage between Washington and Tehran, with one leading expert arguing that “a narrow deal is the likeliest end to this hot war.”

Hopes dim for reopening Hormuz

Oil prices rose and stocks slipped on growing signs that the Strait of Hormuz was likely to remain all but shut for the foreseeable future. Alongside US and Iranian strikes against each other, Tehran fired warning shots on four ships that tried to cross the strait: Iran wants to exert oversight of the channel, a move opposed by global powers. Washington imposed sanctions on the Iranian authority regulating the waterway, and US President Donald Trump threatened to bomb Oman if it worked with Tehran to share control of Hormuz. The number of ships crossing has, predictably, dwindled even further; ABN AMRO economists forecast that even if the strait reopened soon, oil prices would likely remain high for “the coming quarters.”

Fertilizer shortage risks global crisis

The de facto closure of the Strait of Hormuz risks a global food crisis that could extend for years, the UN warned. Global fertilizer companies have slashed production over shortfalls of sulphur, required to make many farming inputs; about half of the global supply passed through the strait before the Iran war. As a result, farmers are likely to produce lower yields in coming harvests. Richer economies like those in Europe are mulling building fertilizer stockpiles, reducing duties on imports, and onshoring production, but poorer ones have limited room to adapt. “We have a window to act, but that window is narrowing,” the head of the UN’s Food and Agriculture Organization said.

Fears of inflation mount

Leaders of major global central banks warned of growing, long-term inflationary pressure stemming from the Middle East conflict. Traders are now betting on at least one Federal Reserve rate increase this year, compared to projections a month ago of policymakers holding firm or even lowering borrowing costs, with the president of the Chicago Fed telling CNBC that “inflation has not proved as temporary as was advertised.” The Bank of Japan’s governor, meanwhile, suggested that what may have initially been a short-term impact on prices “can become persistent if it changes wages, expectations, and price-setting behavior,” and the European Central Bank’s chief economist warned that “second-round [effects] will be with us for a while.”

US digs in on trade pact

The US said it intended to maintain tariffs on some imports from Canada and Mexico, dimming hopes that they could uphold their free trade accord. All three nations must decide by July 1 whether to extend the US-Mexico-Canada Agreement, signed during President Donald Trump’s first term, for another 16 years. But the Trump administration had “significant” trade issues with Canada, US Trade Representative Jamieson Greer said, adding that the “giant” US trade deficit remained a cause of concern. Meanwhile, Mexico — which has in recent years surpassed China to become Washington’s biggest trading partner — this week reported a record monthly trade surplus, beating analysts’ expectations by a factor of 10.

EU seeks to blunt China imports

The EU moved to shield itself from what it sees as a growing threat from Chinese exports, while companies in the bloc said they were deepening reliance on the Asian power’s manufacturing prowess. The EU industry commissioner said Brussels would deploy trade measures, including import quotas and tariffs, across a range of sectors alongside requirements that firms diversify their supply chains away from China as part of a more “muscular” strategy. Yet even as he lauded this “less fragmented approach,” European companies surveyed by the EU Chamber of Commerce in China said they would maintain or expand their supply chains there to drive their global competitiveness. “We don’t see … de-risking becoming a theme,” the business group’s president said.

China and India show AI impact

Two of Asia’s biggest economies showcase the varying economic impact — and opportunities — presented by AI development. China’s optical-communication companies are seeing a boost thanks to huge demand for the underlying hardware required to build out AI infrastructure, including lasers, optical fibers, and transceivers: “Everything is in shortage,” one Guangzhou-based executive told Nikkei. India’s software sector, by contrast, is vulnerable to the growing use of AI in place of programmers and the country lacks major players in AI infrastructure, models, or chips, driving foreign investors to slash their exposure to its stock market. “What markets haven’t fully priced yet is that this isn’t an earnings miss story in India,” an investment adviser told Bloomberg, “it’s a terminal value story.”

Russia faces battlefield pressure

Russia’s armed forces are suffering dual pressures from significant battlefield casualties and struggles to recruit replacements, underscoring Moscow’s growing challenges in its war on Ukraine. Nearly 500,000 Russian soldiers have been killed since the Kremlin launched its full-scale invasion in 2022, the head of Britain’s largest intelligence agency said, after earlier UK assessments said the country had recorded more than 30,000 monthly casualties this year. At the same time, Moscow’s push to recruit contract fighters is showing “signs of strain,” the Institute for the Study of War said: The Kremlin is offering easier paths to citizenship for non-Russian fighters and debt relief for others, while also using force and forms of pressure to get some to sign up.

Africa’s shifting faiths

The pope’s tour through Africa last month cemented the continent as key to Catholicism’s future — but it is not even the fastest-growing form of Christianity there, and soon may not be the biggest. The number of Catholics in Africa grew about fivefold from 1975 to 271 million last year, but numbers of Pentecostals and those of “charismatic faith” increased more than 10 times to 252.3 million. The latter group is more decentralized and draws believers with a “prosperity gospel” promising wealth via faith. Africa’s Catholic leaders have not been impressed: “Today, a lot of humans are thirsting for God, but that thirsting is not always fulfilled in the best way,” one bishop told The Washington Post.
