Ed Conway, Sky News economics editor and author of the new book Trade World, argues that today's surge in global bond yields and the return of trade protectionism are symptoms of a deeper reversal: decades of assumptions that geography no longer matters are breaking down, and the world's physical interdependence is now so deep that a genuine breakdown in trade would be more dangerous than anything since 2008 — even though, so far, the system has proven surprisingly resilient to shocks in the Middle East and the Red Sea.
Bond yields and policy divergence. Conway frames the global rise in yields — JGBs at their highest since the 1990s, UK 30-years at multi-decade highs — as the product of several colliding doubts: fiscal sustainability, assumptions about AI-driven capital spending, and the return of geography as an economic factor after decades of disinflation. He notes a structural shift in UK gilts, where hedge funds without long-term holding incentives have replaced the old buy-and-hold banks as the marginal buyer and seller, adding to volatility. The Bank of England held rates while the Fed, Bank of Japan and ECB hiked, which Conway attributes to timing and a still-unconvinced committee; he expects "maybe one or two" further hikes against a market pricing four or five. The Bank's decision to end quantitative tightening nudged long gilt yields down, narrowing — but not closing — a UK yield premium he traces variously to QT, the legacy of Liz Truss, and doubts about the current government's fiscal discipline.
What Trade World argues. The book extends the thesis of Conway's earlier Material World: physical goods and their journeys matter more than conventional wisdom admits. Nearly every consumer product, he says, is imported or contains imported components, often invisibly — North Sea fish is shipped to China for processing before returning to UK supermarkets as "local" fish fingers; "American" leather is likewise processed in China. Labels only have to disclose where a good was finished, not its full journey, leaving most consumers unaware of how exposed that journey is to disruption.
Wool, cotton and weaponized trade. England's medieval dominance in wool, Conway argues, parallels China's dominance in rare earths today, including using export bans as leverage. Cotton later transformed the UK economy — its share of GDP rose from 2.6% in 1770 to 23% by 1830 — partly through industrial espionage that smuggled Italian milling techniques into England. In the US, cotton production rose from 1.5 million to 167 million pounds between 1790 and 1820 after Eli Whitney's cotton gin made processing American upland cotton viable, fueling the demand that expanded slavery. Modern cotton farming has since narrowed to one dominant species worldwide, a monoculture Conway says leaves global supply vulnerable to disease.
Protectionism and the roots of offshoring. Even Adam Smith, Conway notes, favored tariffs for food security around the 1815 Corn Laws, arguing "defence is of much more importance than opulence" — a precedent he sees echoed in today's tariff debates. Offshoring itself, he argues, did not begin with electronics or cars but with postwar clothing manufacturing, as US department-store buyers moved production to Japan and Hong Kong in the 1940s and 50s; technology and auto firms later copied the model. That history, largely untold, helps explain deindustrialized regions in the US rust belt and the UK Midlands, and the disaffected politics — Trump, Brexit — that followed.
Grain, chokepoints and the Middle East. Russia, never sanctioned on grain, has become the world's dominant wheat exporter, inverting a Cold War dynamic in which US agricultural strength helped defeat the Soviets; adding Ukraine's exports would make Russia's dominance historically unprecedented. Despite more chokepoints being "in play" than ever — Malacca, the Bab el-Mandeb, Panama, Hormuz — trade has adapted: Red Sea rerouting adds only marginal cost, and covert ship-to-ship oil transfers near Iran have kept supply higher, and prices lower, than official figures suggest.
The stakes of a real breakdown. Conway's closing argument is that today's integration is categorically deeper than in 1914, when offshoring and global supply chains did not exist; a genuine breakdown now would make the 2008 financial crisis "look like a walk in the park," akin to a run on the fractional-reserve system underlying global just-in-time trade. He argues China is the most exposed, since its exports must pass the same vulnerable chokepoints, and says he hopes Trump and Xi grasp the stakes — closing on cautious optimism that trade's demonstrated adaptability argues against assuming the worst.
