Two Global Centres of War — Ukraine and Iran: What Force Decides When Diplomacy Sleeps

As of 7 April 2026, the world has at least two major theatres of war that can no longer be viewed in isolation from one another: Ukraine and Iran. Formally, these are different conflicts — one has been raging in Eastern Europe for a fifth year, while the other has, within a matter of weeks, turned into a Middle Eastern crisis of global significance. In reality, however, they are becoming ever more closely intertwined — through weapons, energy, global politics, and the limited diplomatic capacity of the great powers.

The war in Ukraine remains the largest land conflict in Europe since the Second World War. According to AP and Reuters, the front line stretches for roughly 1,250 kilometres; Russia continues its spring offensive, while Kyiv, despite isolated counterstrikes and the partial recovery of territory, is still fighting a war of attrition. At the same time, the diplomatic process has not disappeared entirely: Volodymyr Zelenskyy confirmed his readiness for a limited halt to strikes on energy infrastructure over Orthodox Easter, and Kyiv is expecting new contacts with American mediators after the negotiating track was slowed by the escalation in the Middle East.

What Will Happen to European Property Prices as the Gulf Crisis Unfolds

European property markets entered the new Gulf crisis in a far more delicate position than headline price data initially suggested. Eurostat said house prices in the fourth quarter of 2025 were up 5.1% year on year in the euro area and 5.5% across the EU, which points to a market that had been recovering rather than collapsing. But by early April 2026, UK data already showed how vulnerable that recovery was to a fresh energy and rates shock: Halifax reported a 0.5% monthly fall in house prices in March, while RICS said buyer demand, sales expectations and price expectations had all deteriorated sharply.

The main transmission mechanism is straightforward. The Gulf crisis affects European real estate not directly, but through higher energy prices, higher inflation expectations and more expensive money. The ECB said in March that the war in the Middle East had made the outlook “significantly more uncertain”, creating upside risks to inflation and downside risks to growth, and it revised its 2026 headline inflation projection up to 2.6% because energy prices would be higher. Even after the ceasefire announcement, Reuters reported that oil remained about 40% above pre-conflict levels, which means the inflation shock has eased from panic territory but not disappeared. 

How Resilient Is the Modern Economy, and What Are Its Likely Paths Over the Next Six Months?

The modern world economy is more resilient than it was at the start of the pandemic or during the first energy shock of 2022, but it is not remotely insulated from a new external shock. Its strength lies in the fact that most major central banks entered this crisis with positive interest rates, more policy credibility than in the zero-rate era, and at least some room for targeted fiscal support. Its weakness lies in its continuing dependence on energy prices, maritime logistics, inflation expectations and fragile cross-border confidence. In practical terms, that means the system can absorb another serious shock, but only at the cost of slower growth, stickier inflation and tighter financial conditions.

As of 7 April 2026, the baseline had already deteriorated. World Bank President Ajay Banga said the war in the Middle East would lead to some degree of lower global growth and higher inflation even if the disruption proved relatively short-lived, and he estimated a possible hit to global GDP of roughly 0.3 to 1 percentage point, with inflation rising by as much as 0.9 percentage points depending on the severity and duration of the energy shock. Kristalina Georgieva’s message, as reported by Reuters, was similarly bleak: the direction of travel is towards higher prices and weaker growth.

What the World Economy Faces After the Iranian Crisis

The Iranian crisis has already moved beyond the category of a regional security shock. Even if the acute military phase begins to ease, the world economy is unlikely to return quickly to its previous equilibrium. World Bank President Ajay Banga said the conflict would mean some combination of slower growth and higher inflation even under a relatively short disruption, while IMF Managing Director Kristalina Georgieva warned that the broad direction of travel is towards higher prices and weaker growth.

The immediate transmission mechanism is energy. The Strait of Hormuz remains one of the world’s most important energy chokepoints: roughly 20 million barrels per day moved through it in 2024, and bypass pipeline capacity is only a fraction of that volume. In the current shock, Reuters reported physical crude prices near record highs around $150 a barrel for some grades, while broader benchmark prices moved sharply above $110. That matters because even a partial and temporary disruption changes refinery economics, freight pricing, and inflation expectations across the global system.

An Analysis of Scenarios for the Outbreak of a Third World War After the Expiry of the Ultimatum on 7 April 2026

As of 7 April 2026, the world had not yet entered a Third World War, but it had reached a point at which a regional conflict could shift into a qualitatively new phase. US President Donald Trump demanded that Iran reopen the Strait of Hormuz by the evening of 7 April, Washington time, threatening otherwise to launch large-scale strikes against infrastructure. Iran rejected the ultimatum, insisting not on a temporary ceasefire but on a complete halt to the strikes, guarantees that they would not be repeated, and compensation for the damage. At the same time, Russia and China blocked even a watered-down UN Security Council resolution on protecting shipping in the Strait of Hormuz, while Iran had already struck the Saudi petrochemical complex at Jubail. All this means that, after the deadline expired, the crisis entered a phase in which the cost of error rose sharply.

The main question is this: does that automatically mean the beginning of a Third World War? Not yet. But it is already the sort of crisis in which one additional step could transform a limited war into a multi-layered international confrontation. What makes the situation especially dangerous is that this is not merely a dispute over territory; it concerns control over the Strait of Hormuz, a route through which, in 2024 and the first quarter of 2025, more than a quarter of global seaborne oil trade, around one fifth of global oil and petroleum product consumption, and roughly one fifth of global LNG trade passed. Alternative export routes out of the Gulf are limited to approximately 3.5 to 5.5 million barrels per day, meaning that they cannot fully replace Hormuz. 

The First Scenario: Severe but Still Limited Regional War

Why the United States and Its Allies Cannot Simply Reopen the Strait of Hormuz

At first glance, the problem appears straightforward: if Iran obstructs the Strait of Hormuz, surely the United States and its allies can deploy naval power, clear the route, and restore freedom of navigation. In practice, the situation is far more difficult. The central issue is not whether Washington and its partners can project force into the region. They can. The issue is that reopening the Strait and guaranteeing normal commercial safety are two different things. Even now, after weeks of disruption, a small number of vessels linked to Oman, France, and Japan have been able to pass — but only in what looks increasingly like selective, politically conditioned transit rather than the restoration of ordinary maritime freedom.

The Strait matters because it is one of the world’s most important energy chokepoints. According to the U.S. Energy Information Administration, flows through Hormuz in 2024 and the first quarter of 2025 accounted for more than one-quarter of global seaborne oil trade, about one-fifth of global oil and petroleum product consumption, and around one-fifth of global LNG trade. Any prolonged disruption there therefore affects not only Gulf exporters, but also Asian importers, shipping markets, insurers, refiners, and ultimately consumers well beyond the Middle East.
