The yen should be strengthening as the interest rate gap with America narrows. Instead it remains stubbornly weak. The market may be signalling a deeper problem: Japan needs higher interest rates to support its currency, but decades of cheap money have left the government with an enormous debt burden that becomes progressively more expensive as rates rise.
For forty years, globalisation stripped redundancy from the world economy: warehouses emptied, inventories shrank, suppliers consolidated and production moved wherever it was cheapest. Now war, sanctions and vulnerable shipping routes are reversing the calculation. Companies and governments are rebuilding spare capacity, alternative supply chains and strategic reserves and discovering that resilience has a price.
Europe’s drought is damaging crops, draining rivers and constraining power generation just as the Iran war disrupts oil and fertiliser supplies through Hormuz. Saudi Arabia’s Red Sea escape route is under pressure too. The consequences are already reaching the 2026 harvest; what happens to Europe’s rain and the war this winter could determine the harvest of 2027.
Japan spent three decades exporting cheap capital and became America’s largest foreign creditor. As the yen slid towards ¥164 to the dollar, Washington intervened not just to support Japan, but to contain a threat to the Treasury market and the financial system built on cheap Japanese money.
Britain has world class finance, universities, science and enormous pools of capital. Yet it invests less than any other G7 economy and struggles to build infrastructure, housing and productive capacity. The deeper British malaise is not simply a shortage of money, but a failure to turn wealth, research and investment into things the economy needs.
For centuries, Western influence rested on more than military and economic strength. It also rested on the authority to define legitimacy, progress and the rules of international order. That intellectual monopoly is now being challenged by states pursuing different forms of strategic autonomy. The result is not Western collapse, but the emergence of a more contested and multipolar world.
Military strength no longer rests on armies alone. Artificial intelligence, sovereign debt, industrial capacity, energy security and manufacturing have become parts of the same strategic system. As America competes with China while financing unprecedented technological and military expansion, the real question is no longer who has the strongest military, but which economic system can sustain power over time.
America has accumulated extraordinary financial wealth, yet its productive economy increasingly struggles to deliver affordable housing, modern infrastructure, skilled employment and industrial renewal. For decades, cheap credit and globalisation masked the growing divide between financial markets and the real economy. As energy, trade and technology become geopolitical battlegrounds, that separation is becoming impossible to ignore.
The world’s energy problem is no longer a shortage of oil. It is the steady erosion of the buffers that once absorbed geopolitical shocks. From shrinking US strategic reserves and Europe’s dependence on Russian LNG to refinery attacks and tightening diesel supplies, the global energy system is becoming less resilient and every new crisis carries greater economic risks than the last.
Japan’s government wants to spend while the Bank of Japan tries to tighten. Rising bond yields, a weak yen and stubborn inflation are now testing whether Tokyo can still borrow freely without forcing its central bank back into financial repression.
The Middle East war has not yet forced central banks to raise official interest rates. It has done something more immediate: pushed up bond yields, swap rates and lender funding costs, driving mortgage rates higher across Britain, the United States, Germany, Canada and the wider eurozone.
Nearly 80 countries have introduced emergency measures as the Iran war spreads through the world economy. India is urging citizens to cut fuel use and foreign travel, China’s refiners are slashing throughput, and governments from Bangladesh to South Korea are rationing behaviour as pressure builds across oil, fertiliser, aviation and industrial supply chains.
Two warning lights are beginning to flash simultaneously across the American economy: inflation is rising again while long term borrowing costs climb toward pre 2008 levels. Fuel shocks, debt refinancing, supply chain strain and rising Treasury yields are beginning to expose the growing cost of sustaining the post crisis American financial order.
The Iran crisis is beginning to move beyond oil and into the hidden petrochemical systems that underpin modern consumer life. As naphtha shortages spread across Asia, Britain now faces rising prices in ordinary plastic goods, food packaging, medical disposables and low-cost retail products sold through supermarkets, pound shops, Amazon and eBay.
Martin Wolf sees the return of global imbalances as a problem of surplus countries saving too much and America borrowing too much. But the deeper crisis lies in the dollar-centred globalisation order itself a system that allowed the United States to finance deficits, dominate global finance and hollow out parts of its own industrial base before turning against the consequences.
The Bank of England should have raised interest rates. By holding back, it protected the cheap money regime that inflated house prices, rewarded asset owners, punished savers, and left millions dependent on welfare to survive a broken cost of living settlement.
The Iran war is no longer only a military conflict. It is exposing the fragile economic system built around cheap energy, long supply chains, dollar finance and open chokepoints.
The United Arab Emirates’ decision to leave OPEC is not just about oil production. It reflects a deeper shift in Gulf geopolitics, where alliances are weakening, competition is rising, and national interest now overrides regional coordination.
Oil prices remain elevated above $110 as disruption around the Strait of Hormuz erodes global supply buffers, with inventories falling and tanker flexibility tightening.
Diplomacy has begun in Islamabad, but without direct US–Iran talks the economic damage continues to compound. The war is no longer just about oil — it is moving through fertilizer, aviation, metals and food systems, raising the risk of a broader global shock.
The Middle East war is already pushing up fuel, freight, food and transport costs across India, Southeast Asia and Africa. Europe has not escaped; it is merely waiting for the price shock to arrive.
Britain’s reliance on gas means global shocks still drive domestic costs. The Middle East conflict is not creating a new crisis. It is exposing an old structural weakness.
The dollar system is not breaking under geopolitical pressure — it is being exposed. As Washington shifts from Federal Reserve liquidity support to Treasury-led swap lines, access to dollars is becoming more selective, more strategic, and more political. The result is a three-tier global system in which allies, partners, and outsiders face very different financial realities.
Oil prices are rising not because the Strait of Hormuz has been fully closed, but because it has become unreliable. Some ships are crossing, many are not, and passage depends on shifting security conditions. The result is a degraded chokepoint where uncertainty, not interruption alone, is driving prices higher and forcing markets to reprice global energy risk.
A war driven shock in energy and fertiliser markets is colliding with the debt burden of food importing states. The danger is not simply higher prices. It is that many governments no longer have the financial capacity to absorb them, even though the sums needed to prevent mass hunger are trivial by the standards of the advanced world.
Europe’s aviation system is discovering that fuel was never just a commodity. It was a geopolitical dependency. As disruption around Hormuz deepens, airlines are warning in different ways about supply risk, rising costs, shrinking visibility, and a summer market under strain.
The UN has now voted to call the transatlantic slave trade the gravest crime against humanity. Britain abstained. The United States voted against. That matters because Britain’s wealth was not built only after slavery was challenged. It was built in large part while Britain was one of the paramount powers carrying enslaved Africans across the Atlantic.
The Iran war did not suddenly break a healthy British economy. It hit a country that had already entered 2026 with weak growth, sticky inflation, poor productivity, and an energy system that still transmits global gas stress into household bills, business costs, and market confidence.
The ceasefire may have softened the rhetoric, but it did not restore the Strait of Hormuz as a normal trade artery. With physical cargoes scarce, shipping constrained, and Asia still exposed, oil costs have surged to record highs not seen since the 1970s in real market terms.
The ceasefire did not restore normal transit through Hormuz. It produced a rationed, militarised passage regime in which insurance costs, sanctions risk, legal ambiguity and Iranian discretion matter more than the formal language of de-escalation.
The Iran war did not end dollar power. It exposed the cost of overusing it. The United States still sits at the centre of global finance, but repeated weaponisation of the dollar system is teaching rivals, sanctioned states and even wary partners to hedge, diversify and route around it.
The quoted Brent price is no longer the whole story. The real stress is in the physical oil market, where buyers are paying far more for prompt barrels they can actually secure, ship and refine, and Britain is exposed to the inflation that follows.
The Bank of England’s March decision to hold rates at 3.75 percent looked calm on the surface. Its own minutes show something harsher beneath: a committee split not by the vote itself, but by how far a war-driven energy shock could revive inflation persistence and force a harder policy response.
China’s sovereign market is outperforming because it sits inside a different inflation cycle, a different policy regime and a different ownership structure from the West.
Beijing has not built a replacement for Treasuries, but it has built a bond market that behaves differently enough to attract capital when Western yields jump.
In a fractured global system, China’s bond resilience matters not because it ends dollar dominance, but because it gives investors another place to stand.
Chinese electric vehicles are largely shut out of the U.S. market by tariffs and security rules, yet younger American consumers are increasingly open to them. That creates an awkward political problem: Washington is not just excluding a strategic rival, but denying consumers access to what may be a cheaper and more attractive product.
The United States entered the latest energy shock with core inflation still too firm, pricing power still intact and the final stage of disinflation already stalling. The real risk is not just higher petrol prices. It is that a narrow external shock hardens into a broader inflation psychology that keeps the Federal Reserve trapped and households under pressure.
The Iran war is no longer just an oil price story. It is becoming an Asian fuel allocation crisis in which China protects domestic supply, weaker importers absorb the pain, and the myth of a smooth global energy market begins to collapse.
This is not a rerun of 1973. The old oil shock hit a manufacturing America near the height of its industrial primacy. The present crisis is striking a deindustrialised, debt heavy reserve currency empire whose power rests less on production than on the dollar system, foreign savings and financial credibility. That is why a Hormuz shock now threatens not just fuel prices, but the wider plumbing of the global order.
Donald Trump’s decision to give Iran 10 more days before threatened strikes on its energy infrastructure is being presented as tactical patience. It looks more like strategic constraint. Oil has surged, Wall Street has sold off, bond yields have risen and Tehran has denied any direct talks. The extension makes more sense as a response to market stress than as evidence of diplomatic progress.
The Iran war is pushing oil toward $200 a barrel and driving a broader energy shock through the global economy. In Britain, that shock will translate directly into higher fuel, energy and food costs, with pensioners and low-income households facing the greatest pressure due to fixed incomes and high exposure to essential spending.
The disruption in global shipping is no longer a temporary shock. As conflict pressure builds around the Strait of Hormuz, risk, insurance, and route insecurity are reshaping how goods move, shifting power from contracts to control of chokepoints.
Iran is still earning roughly $160 million a day from oil exports even as the United States and Israel strike Iranian targets. The reason lies in the fragile structure of global energy markets and the strategic choke point of the Strait of Hormuz.
The conflict with Iran has done what decades of geopolitical tension could not: turn the Strait of Hormuz into a commercial dead end. With war risk insurance withdrawn and premiums spiking, tankers and LNG carriers are stranded, energy markets are rattled and fertiliser flows are tightening a supply shock likely to ripple from fuel to food.
Europe’s defence surge is not just a military response. It is a structural reallocation of capital away from productivity and energy competitiveness toward deterrence. As American burden shifting accelerates and energy differentials persist, the real question is whether Europe can finance autonomy without eroding the economic base that sustains it.
For more than forty years, the Chinese economy has sustained growth, industrial upgrading, and social stability under a system Western economics said could not function. It was not just cheap labour, exports, or repression. It was an institutional invention that fused markets with state power. The uncomfortable question is no longer why the Chinese economy rose, but why prevailing theory still cannot explain it.
This is the second article in a series examining why artificial intelligence can raise productivity without raising living standards. While the first piece focused on how AI increases output per hour, this follow-up explains why Britain’s economic structure absorbs those gains instead of translating them into broader prosperity.
Artificial intelligence is beginning to lift productivity in parts of the US economy. In Britain, it is not. The difference is not technological capability, but institutions, incentives, and who is allowed to capture the gains. The claim we are confronting There is now a respectable case that artificial intelligence is beginning to show up in […]
