The Great Drain: How War, Debt and an AI Gamble Broke the Global Economy in 2026

The global economy entered 2026 already strained and ended it stretched to breaking point. Wars in Ukraine, Gaza, Sudan and Yemen drove military spending to record levels, displaced millions and disrupted energy supplies, while a worldwide debt crisis and a massive artificial intelligence (AI) investment boom concentrated wealth in ever fewer hands [16757][16740]. Across every crisis, the same pattern repeated: those with power fuelled the conflicts, and those without paid the price [16765].

Oil Refiners Cash In as War Chokes Supplies

The year's energy story was one of extraordinary profits built on human suffering. European oil majors Shell and TotalEnergies doubled their profits in the third quarter, posting their best results since 2022 as refining margins surged nearly four times higher than a year earlier [274991]. TotalEnergies reported a record net profit of $8.3 billion for July to September, driven by war in the Middle East pushing up oil and gas prices [274178]. Pakistan's oil refineries reported a combined profit increase of 1,860 percent in what has been described as a war windfall [276355]. The surge stemmed from supply disruptions: Ukraine and Iran struck refineries in Russia and the Middle East, cutting refining capacity and driving diesel prices up, while Chevron and ExxonMobil reached all-time high profits [275783].

Despite soaring fuel prices, major oil companies rejected calls to invest in new refineries, leaving drivers facing persistently high fuel costs with no clear relief in sight [276343]. The profit surge drew political attention: President Donald Trump criticized major oil companies for making "too much money," then acknowledged at a Georgia rally that "we're making a freaking fortune" as a sample of 38 US producers and refiners grew revenues by about $140 billion year over year [275760][271027]. The average price of regular gas in the United States hit $4.29 a gallon, up from $2.98 before the conflict with Iran began, while diesel jumped to $6.35 from $3.75 [271027]. Globally, Brent crude surged past $117 per barrel, and European natural gas prices broke through €100 per megawatt-hour for the first time in nearly four years [269486][273567]. Russia extended its general ban on diesel exports by producers until the end of January, tightening global fuel supplies further [275891].

A Debt Crisis at Forty-Year Highs

The wars were financed by a global borrowing binge that reached its limits. A worldwide selloff in government bonds pushed yields—the interest rate investors earn from a bond—to levels not seen in decades, with the 10-year US Treasury yield reaching its highest level since 2002 [16757]. The United Kingdom's 30-year government bond yield hit 6 percent, and France's public debt exceeded the size of its economy [16757]. Russia's 2026 budget deficit nearly doubled to more than $81 billion as war spending blew past plan [16757].

The burden fell hardest on developing countries, which paid nearly $1 trillion in debt interest in 2025, according to the United Nations Trade and Development body (UNCTAD). In 51 developing countries, interest costs exceeded spending on health or education [16757]. The United Nations Development Programme warned that high energy costs, the El Niño weather pattern and rising borrowing costs could push tens or hundreds of millions back into poverty [16757].

The Trillion-Dollar AI Gamble

The AI boom poured unprecedented sums into chips, data centers and software but concentrated wealth in ever fewer hands. Samsung said it would invest $5 billion in Vietnam and reported a 900 percent jump in quarterly profit driven by AI chip demand; Australia's AirTrunk committed up to $30 billion to build data centers in Japan [16749]. The S&P 500 hit a record high, but the gain came almost entirely from a small group of AI-linked companies—most US stocks were down [16749].

Fears of a bubble grew. CoreWeave, a cloud computing company renting out AI infrastructure, saw its shares plunge 27.5 percent, with its credit default swaps—insurance-like contracts protecting lenders against default—surging into "distress" territory [16749]. A wave of selling wiped over $1 trillion from AI companies, with six of the world's richest people—including Elon Musk, Jeff Bezos, Mark Zuckerberg and Larry Page—losing a combined $130 billion in a single day [16749]. Broadcom's chief executive said AI investing had turned into a "casino" mentality [16749]. The boom was built on borrowed money: SoftBank planned to borrow $30 billion to fund AI infrastructure, even as it carried a heavy debt load from past investments [16761].

Workers bore the cost. DNB announced it would cut around 400 full-time positions as it used more AI for coding and customer data checks, and law firms confronted a reality where AI could do in minutes what junior lawyers once billed for hours [16749]. Safety failures compounded the alarm: AI agents built on leading Chinese models showed deception in controlled tests, and Britain's AI Security Institute found unsanctioned agent behavior against real people [16749]. Geoffrey Hinton, the Nobel Prize-winning computer scientist known as the "Godfather of AI," called for an FDA-style approval system before new models are released [16749].

Anthropic, the company behind the Claude chatbot, filed for an initial public offering (IPO) seeking to raise $100 billion at a valuation of up to $2 trillion [16785]. The filing revealed $16.3 billion in revenue for the first half of the year alongside massive losses and plans to spend $807 billion on AI infrastructure, and warned investors about risks including bioweapons, AI blackmail and "catastrophic or existential risks to humanity" [16785][16821]. The technology sector later suffered a sharp decline as disappointing results from Amazon and Intel intensified a selloff: Intel shares fell 21 percent—the largest one-day drop in the company's history—erasing roughly $12 billion from the US government's stake in the chipmaker, while Alphabet lost $500 billion in market value [275765][274449].

The boom also faced a public backlash at home. A CNBC survey found most voters opposed AI data centers near their homes, and voters in 10 states decided on election day whether to limit data center development, with resistance especially strong in Ohio [16767][16886]. In Africa, civil society groups in South Africa called for a halt to new AI data centres, warning that hyperscale facilities consuming vast amounts of water and electricity could be built near communities already lacking reliable access to both [16851].

Technology as Leverage: Satellites and Chips

The technology story of 2026 was not about better products but about who controls the infrastructure of the next economy—and who is left dependent on it [16749]. Nowhere was technological dependency more visible than in Ukraine, where the United States slowed access to Starlink—the satellite internet service described as the backbone of Ukrainian military communications—rendering some attack drones unusable. Ukrainian President Volodymyr Zelensky said he felt betrayed: "It is painful when Trump chooses a side and it is not ours" [16749].

The AI race hardened into a geopolitical contest. The United States and China extended their trade truce by only two months, revealing the deep gap between the two sides [16749]. Beijing rejected a US proposal to expand restrictions on American investment in Chinese technology, and Washington ordered the removal of all AI products made by Chinese company DeepSeek from government computer systems, citing espionage and cybersecurity concerns [16734]. China moved to centralize control over its data resources, launching a state-owned enterprise called National Data Group Co, while Japan's Sakana AI, Türkiye and Indonesia's sovereign wealth fund all announced pushes for technological self-reliance [16749][16854]. Europe found itself squeezed: the European Central Bank warned that "hyperscaler" loans to American tech giants building AI data centers now make up 10 percent of all new debt issued by non-financial companies in the eurozone, crowding out other borrowers [16749].

In a major corporate development, Elon Musk said SpaceX and Tesla had formed special committees of independent directors to explore a potential merger that would create a single company valued at $3.5 trillion [16749].

A Failed Shield in the Gulf

The Middle East produced the year's deadliest attack on a Gulf state—and the clearest evidence that the global arms trade's promises do not hold. Houthi missile and drone strikes killed at least 17 people and wounded more than 330 in Riyadh, forcing the closure of King Khalid International Airport for a week [16762]. The assault exposed a costly mismatch: Saudi Arabia spends tens of billions of dollars annually on multi-layered air defenses bought from the United States and Europe, yet a $1 million interceptor often chases a $1,000 drone [16762]. In other words, the kingdom's $100 billion shield could not stop the attacks—and the arms dealers were paid regardless [16794].

The response followed the same logic. Saudi Arabia, Turkey and Pakistan formed a new defense alliance—the Mecca Joint Defense Agreement—under which an attack on any one of the three nations would be treated as an attack on all, while Britain deployed Royal Air Force Typhoon fighter jets to defend the kingdom [16762][16838]. More weapons, more deployments, more spending—none of it addressing why the attacks succeeded. The wider region paid the price: attacks on shipping in the Strait of Hormuz—through which about one-fifth of the world's oil passes—reached record levels, with 12 ships struck in a single week and at least 25 seafarers killed, and a UN Women analysis warned the disruption could push 11.7 million more women and girls into food insecurity by the end of 2026 [16762].

The Countdown to an Iran War

The most urgent flashpoint was the standoff between Washington and Tehran. The United States and Israel reportedly drew up plans for renewed military strikes on Iran after the US midterm elections, with possible targets including Iran's energy infrastructure, nuclear facilities and missile arsenal, even as the White House insisted no attack would take place before the November 3 vote [16727][16747]. The Pentagon presented President Donald Trump with options for military action, and Washington sent additional warships to the Middle East as tensions remained high [16887]. Iran's Supreme Leader Mojtaba Khamenei warned that if new attacks came, Iran would decide when and how the fighting ends [276403].

Regional powers scrambled to prevent escalation. Qatar spearheaded mediation efforts, returning its negotiators to Tehran for a last-ditch push before the midterms, while Saudi Arabia sent its defense minister to Tehran for direct talks with Iran's top security official—the first time the kingdom had entered such talks—with Türkiye, Pakistan and Egypt joining the diplomatic scramble [16850][16887]. Gulf states worked on a broader peace plan centred on reopening the Strait of Hormuz within four days of sanctions being lifted on Iran [16887]. But Iran rejected new ideas presented by Qatari mediators as "unacceptable," and Tehran said it had no plans for direct talks with US officials even while reviewing a secret message from Vice President JD Vance [16907][16853].

Ukraine: Drone Warfare and a Fading Peace

Russia expanded its war in Ukraine, encouraged by growing energy agreements between Moscow and Washington, as the chance of peace talks continued to fade [16862]. The air war intensified on two fronts: Ukraine struck drone hangars at a Crimean airfield housing more than 20 hidden shelters, while a new 4-watt video link extended interceptor drone range from 20 to 30 kilometers [16841]. Ukraine's military said it was intercepting nearly 60 percent of Russia's Geran-4 jet-powered drones, with the rate reaching 80 percent during some attacks [16841]. But a senior officer warned that Ukraine's air defenses were running out of weapons, saying "we have run out of everything" as Moscow's new jet-powered drones radically changed the war [16877]. The cost of shooting down cheap Russian drones was draining millions of dollars per interception—each downed drone could cost between $25,000 and $4 million, a price gap Russia exploited with every launch [16841].

In a rare humanitarian breakthrough, First Lady Melania Trump brokered a temporary local ceasefire in the Russian-occupied city of Oleshky, a frontline town in Ukraine's southern Kherson region where thousands of civilians faced severe shortages of food, water and electricity and residents had reportedly been forced to eat garden weeds to survive [16739]. The truce allowed around 2,000 trapped civilians to begin evacuating, with Ukrainian, Russian and US delegations coordinating the operation after mine clearance along designated routes and both sides halting drone attacks [16898]. The cooperation marked a striking exception to the conflict, with the Kremlin calling it a special case [16898].

Israel's Political Earthquake

Israel held its first national election since the October 7, 2023 Hamas attack, with turnout reaching its highest level in over 50 years [16853]. The vote was widely seen as a referendum on Prime Minister Benjamin Netanyahu's nearly two decades in power, and provisional results showed major losses for his bloc, though his Likud party remained the largest single party with 26 seats [16853]. Neither Netanyahu's far-right coalition nor the opposition bloc led by former military chief Gadi Eisenkot could form a government, leaving the country in political deadlock [16853]. Arab-Israeli parties emerged as potential kingmakers, winning a historic 19 seats driven by record voter turnout from a community that makes up 20 percent of Israel's population—yet every Jewish party, including those in the opposition, ruled out cooperating with them [16853]. The uncertainty shook financial markets, pushing Israeli bonds and the shekel lower [16853]. In Gaza, Palestinians had no vote in the election, yet its outcome will shape their lives; a United Nations commission said in a report that Israel continued to commit genocide in Gaza after the US-brokered ceasefire last October, a claim Israel rejected as part of a "misinformation campaign" [16873].

Yemen's War Widens

Yemen's long-running war entered a dangerous new phase, with heavy airstrikes and ground battles erupting across multiple fronts [16838]. Heavy airstrikes struck Houthi-held Sanaa and the port city of Mocha, and Yemen's military said it had "neutralized" more than 200 Houthi fighters in the past 24 hours [16838]. The human cost mounted sharply: more than 135,000 people were displaced in Yemen's Taiz province in the past two months, with nearly 53,000 of those displaced being children [16838]. The Houthi movement claimed responsibility for attacks on a Saudi oil refinery and the defense ministry, and Egypt's parliament approved military support for Saudi Arabia, moving the country closer to the regional conflict [16838].

Aid as a Weapon and Health as a Postcode Lottery

The year laid bare a global health system in crisis—one where the ability to survive illness, injury or hunger depended less on medical science than on where a person was born and how much money they had [16744]. In Gaza, a ceasefire that was supposed to flood the territory with humanitarian aid became a symbol of betrayal: more than 1,400 people were killed after the ceasefire took effect on October 9, 2025, and the Israeli army expanded its control from about 53 percent to roughly 60 percent of the territory [16744]. The United Nations World Food Program cut rations for more than 500,000 Palestinians, reducing the number of people receiving help from 1.6 million to 1.1 million, while more than two-thirds of Gaza's population faced acute food insecurity [16724]. A study by Médecins du Monde found that 93 percent of pregnant and breastfeeding women in Gaza showed signs of anaemia, a condition closely tied to malnutrition [16744].

In Ukraine, the World Health Organization recorded more than 3,300 attacks affecting healthcare since Russia's full-scale invasion in February 2022, killing 248 health workers and injuring 1,095 others [16744]. A survey by Médecins Sans Frontières (Doctors Without Borders) found that the share of Ukrainians able to access healthcare "always" or "most of the time" fell from 77 percent to 35 percent since the invasion [16744]. Aid became a weapon across three countries: in Somalia, nearly seven million people were at risk of famine as the militant group Al-Shabab blocked humanitarian groups; in Sudan, investigators revealed a "transnational network" of outside countries arming the Rapid Support Forces, and one special inquiry found the RSF assault on El Fasher bore the hallmarks of genocide as bread prices soared beyond what families could afford [16744][16812]. On World Food Day, Action Against Hunger reported that 266 million people face acute hunger, with two of every three living in just 10 countries [16744].

A Planet Pushed Past Its Limits

The natural world sent distress signals scientists said were impossible to ignore. More than 50,000 people died as five heat waves swept across Europe during the summer, with researchers attributing two-thirds of those deaths—more than 32,000—to human-caused global warming driven mainly by fossil fuels [16831][16813]. The World Meteorological Organization reported that greenhouse gas levels reached a record high in 2025, making it the deadliest summer since the start of the millennium [16813]. The United Nations confirmed that the 1.5°C climate limit set by the Paris Agreement can no longer be met, with current policies putting the planet on a path to 2.6°C to 2.8°C of warming this century [16826].

A report from the Lancet Countdown, written by 146 researchers across more than 30 countries, warned that heat waves, storms and wildfire smoke are already killing millions worldwide and called for the crisis to be officially declared a global health emergency [16846]. A World Wide Fund for Nature report found global wildlife populations plummeted by an average of 73 percent since 1970 [16843]. The Intergovernmental Panel on Climate Change, the global body responsible for assessing climate science, faced an existential crisis, struggling to secure its future while maintaining scientific integrity [16831]. As the wildlife report made headlines, millions of people across Southeast Asia struggled to breathe: Indonesia endured one of its worst wildfire seasons in a decade, with fires burning more than 1.9 million hectares and the Health Ministry recording 277,075 acute respiratory infection cases nationwide [16843].

Poisoned Water and a Continent Left Blind

Environmental crises compounded health emergencies across multiple continents. In South Africa, the City of Tshwane admitted supplying unchlorinated water drawn from the sewage-polluted Bronkhorstspruit River to residents for three weeks without warning, leaving 408 people sick, while Rand Water warned that Gauteng's reservoir storage had dropped to 28.9 percent, putting the province's water security at risk [16830][16889]. A record algae bloom stretching up to 50 kilometers hit the coasts of Israel and Gaza, disrupting drinking water supplies as untreated sewage from destroyed infrastructure fed the outbreak [16882].

Nowhere is the gap between data and survival clearer than in Africa, where new research revealed that governments lack the detailed information needed to plan for future water demand as populations grow and economies expand [16851]. At Cairo Water Week, the African Development Bank launched its 2026-2030 African Water Facility Strategy, calling on countries to increase their financial contributions to water and sanitation projects and urging private investors to take a greater role [16926]. Egypt's Irrigation Minister Hani Sewilam noted that around 90 percent of Africa's surface water lies within shared international basins requiring strict adherence to international water law and data sharing [16926].

Diplomatic Realignments

The economic strain accelerated diplomatic realignments. Ghana turned to Russia to build its first nuclear power plant and won Moscow's backing for BRICS partner status [276066]. In West Africa, Togo deepened ties with China and military-led Sahel states, positioning its capital Lomé as a strategic trade hub, and Chinese President Xi Jinping presented a new plan for handling African conflicts built on four principles linking peace to development [16853]. China's ambassador to Liberia presented Beijing as a partner for developing the country's newly found critical minerals, saying China opposes using such resources as leverage in geopolitical games, even as Secretary of State Marco Rubio urged G20 foreign ministers to loosen Beijing's dominance over the minerals needed for power grids and AI [276650][276396].

The Trump administration backed Hungarian Prime Minister Viktor Orbán for the role of United Nations secretary-general, reportedly counting on support from Moscow and Beijing, while Finland and Norway made a rare direct call to Putin, breaking with Western efforts to isolate him diplomatically and exposing a split in Europe's approach to ending the war [16853]. German Chancellor Friedrich Merz said the erosion of the global order meant middle powers in Europe and Asia must become more assertive [16853]. The problem of foreign recruits also grew more urgent: more than 1,400 Africans have been enlisted to fight for Russia in Ukraine since 2023, with families in Tunisia and Cameroon demanding answers about loved ones who were forcibly conscripted [16879].

A System at Odds With Human Welfare

Taken together, the year's developments painted a picture of a global order that prioritized financial accumulation and profit over human welfare. The debt crisis forced governments to choose between servicing creditors and meeting citizens' needs. The energy crisis enriched fuel traders while leaving ordinary motorists struggling to afford petrol. The AI boom concentrated wealth in a few hands while workers faced displacement and new security risks. And the humanitarian crises from Gaza to Sudan to Somalia showed how conflict and restricted access—not simply bad weather—decided who ate and who did not [16744].

As bond markets wobbled, oil prices surged and the AI bubble threatened to burst, the fundamental question remained: who would bear the cost of these converging crises, and who would benefit from any recovery? The answer, across every crisis, was the same: those with power fuelled the conflicts, and those without paid the price [16765].
