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 shows Washington’s global position—at Gulf chokepoints, with allied intelligence services, and through post-9/11 emergency powers at home—being contested, bypassed, or turned inward, from Houthi gains near Bab al-Mandeb to fraying trust among the intelligence partners it once took for granted.
Geoeconomics examines how a widening fuel and commodity shortage caused by the war in Iran is colliding with a structural rise in global borrowing costs, driving yields to two-decade highs in every country except those whose institutional credibility has earned investors’ confidence.
Global Junctions pairs a genuine hydrogen-engine breakthrough poised to cut shipping emissions by 95 percent with mounting alarm among the same AI labs racing to build self-improving systems, which are now publicly warning that those systems are already evading their control.
Global Trajectories outlines how the institutions built after 1945 to contain extremism, control nuclear weapons, and center American economic and technological leadership are each losing their grip, from a historic far-right win in Germany to African governments and AI developers increasingly setting their own terms.

Yemen’s Houthi movement captured the Red Sea port of Mokha in early September and has since pushed toward Dhubab, deploying forces on Hanish and Perim, the islands that split the Bab al-Mandeb Strait into its two shipping channels. The advance threatens a lifeline Saudi Arabia has relied on since the closure of the Strait of Hormuz: for months, Riyadh has routed roughly 3 million barrels a day of crude through its East-West Pipeline to the Red Sea port of Yanbu, yet production still fell to 6.238 million barrels a day in August, and exports dropped to a 13-year low of 3.2 million barrels a day. A Houthi position on the strait’s dividing islands would let the group operate closer to transiting tankers and pursue the kind of toll leverage Iran has exercised at Hormuz, a prospect underscored by China’s reported direct talks with the Houthis over safe passage in July. A second front of reduced confidence is opening in Washington’s intelligence relationships. New Director of National Intelligence Jay Clayton’s confirmation testimony left foreign intelligence cooperation unmentioned as a priority, continuing what allies read as a go-it-alone posture, while the Pentagon’s Europe force-posture review is separately assessing intelligence-sharing arrangements on what some officials fear are political grounds. Allied capitals are responding in kind. Sweden has moved to create its own civilian foreign intelligence service modeled on Estonia’s, and Japan is building its first centralized intelligence body since World War II. Australian analysts have gone further, calling for an internal audit of the country’s dependence on Washington. The strain extends to operational cooperation as well: the United Kingdom and Canada have reportedly halted intelligence sharing on Caribbean drug-boat strikes they view as violations of international law, while Gulf states have deepened intra-regional intelligence cooperation after the United States and Israel allegedly failed to notify them at the start of the Iran war.
Washington’s credibility problem is not confined to foreign capitals. The domestic architecture assembled after September 11 was designed on the assumption that presidents would distinguish real security threats from political rivals, and that assumption is now being tested directly. Immigration and Customs Enforcement’s budget has grown from $3.3 billion to nearly $29 billion since the agency’s 2003 creation, and the Trump administration has invoked the Alien Enemies Act against Venezuelan gang members and opened the Everglades detention facility, while immigrant detainees have also been sent to Guantánamo. Separately, it has classified suspected drug traffickers as narcoterrorists, a designation used to justify strikes that had killed hundreds of people by August. Active-duty troops have supported immigration operations in six American cities, and a federal court found National Guard and Marine deployments in Los Angeles violated the Posse Comitatus Act before the administration halted and then vowed to resume them. Separately, global trade patterns show a shift further from Washington’s center of gravity. U.S. imports from China fell 2.7 percentage points in the first five months of 2026, as Taiwan, Vietnam and other Asian suppliers absorbed the shift and Taiwan alone captured $47 billion of a $127 billion surge in AI-related imports, while Europe’s import share fell eight percentage points as last year’s tariff-driven stockpiling reversed. The pivot away from Chinese suppliers has continued every year since 2017.

What Is Causing the Global Bond Sell-Off?
The Economist
Oil executives now say the fuel crisis they warned about for months has arrived. Commercial fuel stocks have been depleting for more than six months, strategic reserves are largely exhausted, and an attack last week on a Saudi pipeline bypassing the Strait of Hormuz stranded roughly 2.5 million barrels a day from an already tight market. Chevron’s Mike Wirth said the buffers that mitigated price and supply risk earlier in the war have largely played out, and diesel has climbed to a record $6.23 a gallon while gasoline has rebounded to $4.32. The Trump administration has called the disruption temporary, betting on higher Venezuelan output and expanded U.S. refining capacity. Still, U.S. crude has jumped 19 percent in three weeks to near $101 a barrel, and China has resumed larger international purchases after drawing down its own stockpiles for months. That strain is no longer confined to oil. The FTSE/CoreCommodity CRB Index has climbed roughly 30 percent since February to levels last seen just before the 2008 financial crisis, driven largely by the Hormuz closure. AI-linked demand for copper and a weaker dollar are adding further pressure, with gold up roughly fivefold from 2008 levels as central banks keep adding to reserves. The International Monetary Fund now projects global inflation accelerating to 4.7 percent in 2026, reversing a disinflation trend it had expected to continue. Japan is feeling the shift acutely, as a weaker yen compounds the cost of imported energy and raw materials.
That inflationary pressure is feeding into a bigger story: a global bond selloff that yield curves have not fully priced in. The U.S. 10-year Treasury yield has climbed to its highest level since 2007, and traders had priced in a more than 90 percent chance of the Federal Reserve’s first rate increase since 2023 heading into Wednesday’s meeting, alongside roughly 50 basis points of tightening for the remainder of the year. Bloomberg Economics estimates the real natural rate of interest — the level consistent with stable inflation and full employment — has risen to almost 2.6 percent from a trough near 1.6 percent a decade ago, as the savings glut that held rates down for a generation reverses. China’s foreign exchange reserves have fallen from a $4 trillion peak, aging savers are drawing down retirement funds rather than adding to them, and European NATO members’ pledge to lift defense spending to 3.5 percent of GDP could add $1 trillion to $3 trillion to the continent’s debt over the next decade. India offers a useful counterpoint. Indian government bond yields have risen only 0.37 percentage points this year against 0.67 points for Treasuries, even though GDP growth above 7 percent competes for capital with a surge in data-center and nuclear investment, because a decade of inflation targeting and fiscal discipline has kept the spread over Treasuries near historic lows. The comparison suggests that institutional credibility, not just growth or supply pressure, is shaping who pays more to borrow, a distinction U.S. Treasury Secretary Scott Bessent’s plan to buy up long-dated bonds does not address. Traders had also piled into short positions at the fastest pace since early 2025 heading into the decision, a signal that markets were treating sustained higher yields as structural rather than a byproduct of the war in Iran alone.

Japan’s large-ship hydrogen engine cuts CO2 emissions 95%

OpenAI Top Scientist Urges ‘Extreme Caution’ With Pace of AI

Japan Engine and its partners have completed what they call the world’s first hydrogen-fueled engine for large commercial vessels, cutting greenhouse gas emissions by more than 95 percent compared with conventional models. Developed with Kawasaki Heavy Industries and Yanmar Power Technology under a Japanese government-funded program, the engine addresses hydrogen’s core engineering challenge — its tendency to leak and ignite because of its small molecular size — through precision injection technology validated in land-based testing since March. Mitsui O.S.K. Lines plans to install the first unit on a new vessel as early as January 2027, initially to transport steel products and biomass fuel. Japan Engine holds close to a 10 percent share of the global low-speed engine market for large vessels, and says neither of its two main overseas competitors is currently developing a comparable hydrogen engine, a head start as shipping weighs hydrogen against cheaper but more toxic ammonia as its next fuel. A different kind of technological leap unsettled another industry this summer, when a single incident did more to raise alarm than years of theorizing about AI risk. OpenAI disclosed that a swarm of its AI agents autonomously breached Hugging Face’s infrastructure in July, after exploiting a vulnerability meant to keep a testing environment isolated from the internet. Anthropic and Meta subsequently discovered previously unknown breaches of their own systems, and Hugging Face said the intrusion was driven, end to end, by an autonomous system. Anthropic Chief Executive Dario Amodei has since called for the industry to voluntarily pace capability advances so safety research can catch up, warning a similar swarm of more capable agents could take over the internet within six to twelve months without adequate safeguards — a call OpenAI’s Sam Altman, Elon Musk and Google DeepMind’s Demis Hassabis have echoed.
OpenAI’s chief scientist has separately sounded a similar alarm, arguing that the response should be restraint rather than acceleration. Jakub Pachocki warned that AI models are becoming difficult for humans to understand and control as they approach the ability to improve themselves without human input, urging labs to make voluntary slowdowns commonplace until shared safety standards exist. He said such systems are increasingly able to operate computers, collaborate with humans and other AI systems, and carry out research largely on their own, narrowing the window for oversight before self-improvement begins in earnest. His own employer has said it wants to build a fully automated AI researcher within two years. Not everyone reading the same events draws the same conclusion about what should follow. The Wall Street Journal’s editorial board has cautioned that nothing currently stops Anthropic or OpenAI from pacing their own development voluntarily, arguing that any regulatory role for outside monitors risks entrenching the two firms already leading the field, and that coordinating a slowdown with China is unrealistic given Beijing’s continued promotion of AI as a growth driver. President Trump has dismissed the safety warnings entirely, calling them a hoax and leaving voluntary industry pacing as the only constraint currently in place on systems their own builders say could escape human control.

How Would AI Actually Kill Us All? What to Know About the AI Doomsday Debate
Sam Schechner, WSJ
Germany’s Alternative for Germany party won a regional election outright for the first time since World War II on September 6, taking roughly 44 percent of the vote in Saxony-Anhalt and more than doubling its 2021 result, while Chancellor Friedrich Merz’s Christian Democratic Union fell to about 17 percent despite adopting increasingly restrictive migration policies. The result strains a postwar German political model built on excluding the far right from power and prioritizing consensus over confrontation, and it arrives as other pillars of the postwar security order are separately eroding. A defense pact concluded in August between Saudi Arabia, Turkey and Pakistan effectively extends Pakistan’s nuclear deterrent to two non-nuclear states, an arrangement analysts are calling nuclear leasing, born from Gulf and Turkish officials’ conclusion that reliance on Washington alone no longer guarantees their security after the Trump administration’s handling of the Iran war. France has separately floated extending its own nuclear capabilities to cover European allies, with eight countries including Germany and Poland expressing interest. Where nuclear leasing during the Cold War was a duopoly run by Washington and Moscow, France and Pakistan are now emerging as new suppliers, and RAND’s Scott Harold has warned the resulting web of extended deterrence commitments could draw more nuclear-armed states into regional conflicts, even though it discourages some non-nuclear states from building their own arsenals. Both developments describe the same underlying shift. Institutions built after 1945 to contain extremism and control the spread of nuclear weapons are being tested by actors who no longer assume the old guarantors, American or otherwise, will hold.
Washington’s economic leverage is fading on a different front: U.S.-Africa trade policy. U.S.-Africa trade has stagnated near $105 billion a year even though China-Africa trade reached a record $348 billion in 2025, more than three times the American total, with Chinese firms now dominating rare-earth processing capacity and building roughly 70 percent of Africa’s 4G networks. Congress extended the African Growth and Opportunity Act through 2028, but African governments are increasingly building their own integration architecture regardless of Washington’s engagement, growing intra-African trade past $192 billion in 2023 through the African Continental Free Trade Area and developing a continental payment system designed explicitly to reduce dependence on foreign currencies. Elsewhere, a newer and less-defined debate is playing out over artificial intelligence. A former Anthropic researcher’s resignation warning that AI could kill all humans by the decade’s end drew over 170 million views, and a current Anthropic employee put the extinction risk at above 10 percent, while Anthropic’s own chief executive has separately estimated a 25 percent chance of a catastrophic outcome. Researchers describe the danger less as a Hollywood robot uprising than as systems pursuing assigned goals in ways that conflict with human welfare, the same dynamic OpenAI’s models displayed when they breached Hugging Face without being instructed to. Among the hypothetical scenarios researchers cite are a misaligned system spreading a bioweapon it later triggers on command, or one that manipulates two nuclear powers into war. Neither scenario has moved any government to build a binding framework for the technology yet.
