The global economy is entering a difficult phase in which geopolitics, energy security and monetary policy are reinforcing one another. The immediate trigger is the widening US-Israeli war with Iran and the resulting disruption around the Strait of Hormuz, a route through which roughly one-fifth of the world’s oil normally passes. The shock has pushed energy prices sharply higher and placed inflation back at the centre of international economic policy.
Finance ministers and central bankers meeting at the IMF and World Bank gatherings in Bangkok face a problem more complicated than a conventional oil-price spike. Higher fuel costs raise transport and production expenses, weaken household purchasing power and can force central banks to keep interest rates elevated even as growth slows. Reuters reported that the IMF still expected global growth of about 3% in 2026, but officials warned that the resilience of the expansion was becoming more fragile as energy markets tightened.
Why this shock is different
Energy disruptions are not merely a price story. They redistribute income between importers and exporters, expose countries with limited fiscal space and increase the cost of food, fertiliser and shipping. IMF research cited by Reuters found that sharp food and energy-price increases are becoming a more common source of crises because they can lift inflation expectations, worsen poverty and undermine financial stability.
Europe is particularly exposed. Eurozone inflation reached 3.8% in September, its highest level since September 2023, while energy prices rose 18.8% year-on-year, up from 14.3% in August. European governments have responded with subsidies and other relief measures, but those policies create a trade-off: they cushion consumers while adding pressure to public finances and potentially sustaining demand for scarce fuel.
“The conflict has caused major disruptions to fuel supplies from the Middle East, including from the Strait of Hormuz,” Le Monde reported, noting that higher oil prices were weighing on European households and company margins.
The policy dilemma
For central banks, the danger is a return of “stagflation”: weaker output combined with persistent price pressure. Raising rates can restrain second-round inflation, but it cannot produce more oil or reopen a shipping lane. Holding rates too low, meanwhile, risks allowing a temporary energy shock to become embedded in wages, rents and business pricing.
The United States illustrates the tension. Recent data showed stronger-than-previously-estimated second-quarter growth, with real GDP revised to an annualised 2.2% and consumer spending growth revised to 3.8%. Yet September employment growth was unexpectedly weak, with only 29,000 jobs added and unemployment reaching 4.2%, according to figures reported by Anadolu Agency. A resilient economy gives policymakers room to fight inflation; a weakening labour market argues for caution.
Governments also face a political choice. Emergency fuel support can prevent an immediate cost-of-living crisis, but broad subsidies tend to benefit higher-consuming households as well as the poor. Targeted transfers are more efficient, though harder to administer and less visible politically. The G7’s reported decision to release 100 million barrels from emergency reserves shows that governments are willing to intervene, but strategic stocks can only buy time if supply routes remain impaired.
Geopolitics and the limits of reassurance
The crisis is also exposing the limits of diplomatic signalling. The United States has sought to reduce fears of an even wider confrontation, while Iran has reportedly rejected an American proposal concerning the reopening of Hormuz as insufficient. Markets have responded quickly to every change in perceived escalation risk: oil has fallen when an attack appeared less likely and risen when shipping or infrastructure seemed threatened.
That volatility complicates planning for businesses and households. Companies may delay investment, airlines and manufacturers may pass costs to customers, and poorer importing countries may face pressure on currencies and food bills. The World Bank’s Ajay Banga warned that economic pressures were building again even after global growth held up better than expected during the initial closure of the strait.
What comes next
The next phase will depend on three variables: whether Hormuz traffic can resume reliably, whether governments can prevent energy inflation from spreading through the wider economy, and whether the conflict remains contained. A sustained reopening would ease pressure quickly, but it would not erase the fiscal damage or the investment uncertainty created by the crisis.
The deeper lesson is that energy diversification is no longer only a climate policy. Renewable power, efficiency, storage and alternative supply routes are increasingly treated as tools of national resilience. Yet the transition itself requires capital, stable regulation and years of investment—precisely when higher interest rates and emergency spending make both more difficult.
The immediate economic outlook is therefore less about one forecast than about competing risks. Growth may continue, but each additional week of disruption increases the chance that an energy shock becomes a broader inflation and debt problem. Policymakers can soften that outcome; they cannot fully control the geopolitical forces driving it.
