Welcome to this week’s edition of Geopolitics & the Day After. Each week, we curate and synthesize key developments from global politics, economics, and financial markets, drawing from a wide range of trusted sources. Our goal is to provide you with a clear, concise, and insightful overview of the forces transforming the world today and shaping tomorrow. Below is an overview of what we cover this week:
Geopolitical Concerns tracks how militant groups and longtime allies alike are testing the durability of a US-anchored order, from the Houthis’ seizure of a Red Sea chokepoint to Canada’s EU outreach and Brazil’s election turning on a judicial crisis.
Geoeconomics reveals how a widening fiscal gap and Saudi Arabia’s oil cutoff strain the same resource—capital—as bond markets absorb more government borrowing while the pool of buyers willing to hold that debt keeps shrinking.
Global Junctions maps the physical and financial scaffolding behind the AI boom, as Big Tech shifts $300 billion in exposure off its own balance sheets while Huawei’s new chips and lithography breakthroughs harden China’s bid for full supply-chain self-sufficiency.
Global Trajectories surveys four long-run trends moving the wrong way at once: stalling incomes for billions of people, shrinking freshwater reserves, falling student test scores, and a widening premium on a narrow class of elite technical talent.

The Houthi armed group’s capture of the Red Sea port of Mocha has handed Iran-aligned forces direct influence over two of the world’s most important maritime chokepoints at once. Together with Iran’s disruption of the Strait of Hormuz, the group’s advance along the Bab al-Mandab strait gives Tehran and its allies simultaneous leverage over the passage connecting the Gulf of Aden to the Red Sea and the waterway linking the Gulf to open water. The offensive exposed years of fragmentation among Saudi-backed factions, which withdrew as Houthi forces used the relative calm since a 2022 truce to expand missile and drone production, and it has already drawn Houthi attacks on Saudi energy infrastructure that Washington must now weigh against its own truce with the group. In Europe, meanwhile, the EU’s top military official, General Sean Clancy, has named Russia’s hybrid campaign, including drone incursions, digital sabotage, and migrant flows across EU borders, as the bloc’s most significant strategic threat. Germany’s decision to formally blame Moscow for a drone sent to Leipzig airport, and the EU’s subsequent moves to restrict Russian travel and fuel-tanker traffic, follow the same warning, though Clancy insists rising European defense budgets show no sign of fatigue.
A different set of alignments is shifting elsewhere, driven by trade rather than security. European Commission President Ursula von der Leyen has offered to make Canada the EU’s first “associate member.” The offer comes as Ottawa seeks closer ties with Brussels to cut its dependence on US trade amid Trump’s tariffs and 51st state rhetoric. Von der Leyen framed the proposed partnership, which covers manufacturing, defense production, the Arctic, and critical minerals, as built on shared democratic values rather than trade alone, though no precedent exists for what associate membership would actually require, including whether all 27 EU members would need to approve it. Turning to Brazil, President Luiz Inácio Lula da Silva and challenger Flávio Bolsonaro are deadlocked at roughly 47% each in polling ahead of an October election, with a bank-fraud scandal implicating allies of both camps. Private messages linking a Supreme Court justice to the fraud investigation of a former bank owner have opened an internal rift within Brazil’s judiciary. Bolsonaro’s son and Senate candidate, Flávio, has tried to turn that rift into a referendum on judicial power, though the same scandal touches his own fundraising ties. Roughly half of respondents expect the crisis to hurt Lula more, underscoring how domestic institutional battles, as much as economic performance, are now shaping electoral outcomes in major democracies.

The O-Ring Risk to the Global Economy

Soaring bond yields, gaping deficits and towering debts: what could go wrong?
The Economist
Bond markets aren’t just running a temperature
Mohamed El-Erian, The Economist
Peter Orszag’s O-Ring economy theory, drawn from a 1993 economics paper by Michael Kremer that borrowed its logic from the Challenger space shuttle disaster, argues that global supply chains have grown so interdependent that a single weak link can collapse the value of everything connected to it. The theory takes its name from the rubber seal whose failure in cold weather destroyed the shuttle in 1986. Physicist Richard Feynman showed that this one small part, not the ship’s most sophisticated systems, decided the outcome, and Orszag applies the same logic to economics, where output reflects the multiplied reliability of every stage rather than their sum. Applied to this decade’s run of shocks, including the pandemic, the wars in Ukraine and Iran, tariff standoffs, and China’s rare-earth export limits, the logic reframes them not as unconnected events but as the predictable output of chains that grow more fragile as they lengthen, a dynamic now visible in the oil market. Saudi Aramco has told at least two European refining customers they will receive no crude next month under long-term contracts. The decision follows drone attacks that forced the kingdom to shut its East-West pipeline last week. Aramco is working to partially restart the line within days and reach full capacity within six weeks, but the gap has already sent Dated Brent above $130 a barrel and pushed Poland’s Orlen to hunt for replacement barrels. The shutdown has also forced Aramco to redirect spot cargoes through the Strait of Hormuz toward Asia, a route it had largely avoided during the regional conflict, leaving European refiners, who imported 577,000 barrels a day from Saudi Arabia in June, facing either Houthi-threatened Red Sea passage or a roughly five-week detour around Africa.
A structural mismatch is also building in sovereign bond markets, as the supply of government debt grows faster than the pool of investors willing to hold it. This week, the yield on ten-year US Treasuries exceeded 5% for the first time in two decades, and the 30-year yield pushed above 5.35%, a point at which interest payments already consume around a fifth of US tax revenue on a debt stock that has doubled to $40 trillion in a decade. The median yield on rich-world ten-year government bonds has climbed above 4%, roughly five times its 2015-21 average, while advanced-economy public debt has risen to about 110% of GDP from 70% in the early 2000s. Treasury Secretary Scott Bessent has characterized the spike as a passing “fever” and intervened by buying back longer-dated bonds, but Mohamed El-Erian, former PIMCO chief executive, argues the more accurate diagnosis is a bond market clearing room for AI-driven capital spending. Historically reliable buyers, including China, Gulf sovereign funds, Japan’s currency interventions, and Norway’s wealth fund, are pulling back at the same time issuance needs are rising. Britain, Italy, and France would each need primary surpluses above 1% of GDP just to stabilize their debt ratios at today’s five-year yields, a fiscal adjustment none of them is currently making, which leaves borrowing costs positioned to keep climbing rather than settle.

Big Tech companies have issued up to $300 billion in guarantees over the past year to back debt for AI data centers and chips, and most of that exposure never lands on their own balance sheets. The guarantees typically underwrite debt raised by a special-purpose vehicle that owns the infrastructure rather than the tech company itself, letting a firm lend its credit strength to a project without booking the full liability. Bankers describe the structure as balance-sheet efficient, and it typically prices at just 100 to 150 basis points above the guarantor’s own debt. Meta pioneered the approach last year with a $28 billion guarantee behind its Hyperion data center in Louisiana and extended the same structure in July to a second, 1-gigawatt project in El Paso. Broadcom followed with $29 billion in support for chips leased to Anthropic, and Nvidia has extended $105 billion in guarantees to a SoftBank subsidiary building an Ohio campus for OpenAI that will run Nvidia hardware exclusively for 20 years. China’s own push to build the hardware behind that same AI race is advancing just as fast, centered on Huawei’s expanding chip lineup. Huawei unveiled more than ten new AI chipsets at its annual Huawei Connect conference. The lineup includes an Ascend 960 accelerator that executives say is running three quarters ahead of schedule and performing at double the previous generation’s capability. Company leaders said domestic demand for Ascend chips is already outstripping supply, and one Huawei executive estimated the broader global chip shortage would not ease until around 2029, with China’s own supply-demand balance likely taking even longer to reach.
The self-sufficiency push runs up the supply chain too. Yuliangsheng, a Shanghai manufacturer reported to have ties to Huawei, which the company denies, has co-developed China’s first domestic advanced deep-ultraviolet lithography machine, part of a broader effort to eliminate foreign technology from the country’s chip supply chain. German suppliers Trumpf and Zeiss, meanwhile, are expanding their own presence in Taiwan to meet broader demand for advanced chipmaking tools. Trumpf is tripling its EUV laser-source capacity over two years, and Zeiss, the exclusive optics supplier for EUV lithography systems, is opening a third innovation center focused on semiconductors. Beijing’s state-directed science model treats AI as a tool built to solve national problems on command. The approach is being echoed in the Trump administration’s own science-policy overhaul under adviser Michael Kratsios, whose new Genesis Mission and X-Labs programs borrow directly from China’s state-key-laboratory approach, replacing peer review with state-appointed reviewers empowered to fund high-risk projects unilaterally, an implicit admission that the US cannot match China’s advantage in sheer numbers of STEM graduates. China, meanwhile, is exporting the model as much as using it domestically, positioning cities like Nanning as a showcase for AI-driven agriculture and manufacturing aimed at Southeast Asian neighbors. The contrast will shape not just who builds the fastest chips but whose approach to deploying them the rest of the world ultimately adopts.

The GDP-per-person slowdown threatens global living standards

Decline of freshwater reserves has ‘serious future implications,’ UN body warns

Yes, Children Really Are Getting Dumber

Olympiad Man has displaced Davos Man
The Economist
Roughly 3.3 billion people now live in places where GDP per person grew at half the rate or less over the decade to 2024 than in the prior decade. That is up from 1.1 billion people a decade earlier, and more than 730 million are living through outright declines in income per person. China, Russia, Germany, and Brazil have all joined that low-growth club for different reasons: weak productivity growth paired with high immigration in the rich world, the end of a decade-old commodities boom for exporters, and, in China’s case, the exhaustion of manufacturing-led catch-up growth. Freshwater reserves are eroding on a comparable global scale, though for very different reasons: 42% of the world’s land area held below-normal freshwater reserves in 2025. That is up from under 20% at the start of the 2000s, and only 36% of the world’s river basins showed normal flows that year, one of the driest in 35 years. Glaciers lost roughly 1,400 gigatonnes of water between 2023 and 2025, and some small-glacier regions in the Alps, Scandinavia, and the Caucasus may already have passed what hydrologists call “peak water,” the point after which melt stops swelling rivers and starts signaling their long-term decline. At least 62,500 deaths have been linked to floods and other hydrological events since 2021, 80% of them in Africa and Asia.
A different kind of slowdown is showing up in classrooms, where US math and reading scores dropped by the equivalent of three-quarters of a year of learning between 2018 and 2025, trailing China, Singapore, Japan, South Korea, Britain, Canada, and Australia. Reading performance fell in roughly three-fourths of countries over the same period, and instances of “hasty reading,” in which students read quickly but inaccurately, nearly doubled to 9%. Students who did not use AI for drafting text scored 28 points higher on average than those who used it almost daily, roughly a year and a half of learning. While broad measures of income and cognitive skill flatten or decline, a narrow class of technically elite specialists is capturing an outsized share of the gains AI is generating. Anthropic’s chief executive trained with America’s physics Olympiad squad, though he did not make the starting lineup; OpenAI added math medalist Paul Christiano to its board, and Google paid $2.7 billion in 2024 to hire Noam Shazeer, a perfect scorer in 1994, a concentration of talent that also runs through trading firms like Two Sigma and Jane Street. The result is a widening gap between a general population whose living standards and educational outcomes are stalling and a small, highly specialized elite whose skills are being rewarded at a scale no previous generation of talent has seen.
