When Flows Become the New Frontiers
What if the world was no longer organized around regions , but around flows?
For a long time, we learned to read the world by region: the Middle East, Europe, the Indo-Pacific, Africa, and Latin America. This reading remains useful. It allows us to understand histories, borders, rivalries, peoples, and sovereignties. But it is no longer enough.
Since the start of Russia’s invasion of Ukraine, it has become increasingly clear that crises are no longer confined to their original areas. They circulate, move around, and contaminate markets, maritime routes, energy prices, food supplies, and the calculations of the great powers.
So the real question may be this: what if the world was no longer just organized around regions, but around flows?
Not because the territories would have lost their importance. A state always exists through its territory, borders, people and institutions. But contemporary power is increasingly measured by the ability to protect, control or disrupt the flows that make the world economy work.
The Strait of Hormuz perfectly illustrates this shift. It is not a large territory. It is not a capital. It is not an empire. It’s a passage. And yet, this shift can weigh on oil prices, inflation, central bank decisions, ASEAN discussions, food security in fragile countries, and the strategy of both the United States and China.
According to the US Energy Information Administration, oil flows through Ormuz amounted to about 20.9 million barrels per day in the first half of 2025, i.e. nearly 20% of global consumption of petroleum liquids and about a quarter of global maritime trade in oil. The UNCTAD also recalls that this strait transports not only oil, but also significant volumes of liquefied natural gas and fertilizers. In other words, Ormuz is not just an energy route; it is an artery of globalization.
It is here that geopolitics changes shape. Yesterday, controlling a territory made it possible to dominate a space. Today, disrupting a flow can be enough to affect several economies at once. A militarily weaker actor may become dangerous not because he can conquer, but because he can interrupt.
This capacity of nuisance becomes a form of power.
We also see it with Bab el-Mandeb and the Red Sea. The Houthis’ threats to navigation show that straits are no longer just points on a maritime map. They are becoming political levers. A drone, a mine, a missile, or sometimes simply the fear of an attack can be enough to change a trade route. Ships are bypassing, delays are lengthening, insurance is rising, and costs are being passed on to consumers. A military crisis then becomes a global economic crisis.
Perhaps most important is the transformation of the energy crisis into a food crisis. If energy increases, fertilizer becomes scarcer or more expensive, and shipping routes slow down, food prices eventually rise.
That is why a crisis in Hormuz can worsen a food crisis thousands of miles away. The World Food Programme has warned about the possible effects of rising fuel, fertilizer and logistics costs on global hunger. This idea is essential: a war can produce hunger without bombing a single field. It can affect harvests by the price of diesel, yields by the price of fertilizers, and humanitarian aid by the cost of transport.
This is also why ASEAN talks are so important. A crisis around Hormuz is not just a Middle Eastern problem. For Asia, a major consumer of imported energy, it is a direct question of economic stability. The Middle East generates tension. Asia is paying a part of the price. This interdependence blurs the old regional categories ([The Washington Post][4]).
At the same time, the South China Sea is a reminder that the Indo-Pacific has its own fault lines. Tensions between China and the Philippines show that maritime flows have become a language of power. Beijing therefore does not look at Hormuz alone as a distant file. China is watching how Washington reacts, how many fronts America can handle, how long it can remain credible, and how Asian allies interpret this dispersion.
However, we must avoid a conclusion that is too rapid. The regions have not disappeared. Iran remains in the Middle East. China remains in Asia. Russia remains in Europe and Eurasia; territories, borders, armies, and political regimes still matter. But a second map is imposed on top of the first: that of flows.
This is the map of oil tankers, submarine cables, electronic chips, currencies, ports, fertilizers, cereals, satellites, data and maritime routes.
This map is less visible than that of the borders, but it increasingly explains the balance of power. A country may be far from war, and yet still suffer the consequences. A state may not participate in a conflict and see its inflation increase. A company can become a geopolitical player because it transports, insures, finances or connects an essential flow. A local crisis can become global because globalization connects everything that politics still believed to separate.
The geopolitics of the twenty-first century thus no longer pits only states for territories. It also opposes actors who want to secure, control or disrupt the major flows on which the global economy depends.
This is a major transformation
Power is no longer just about holding a front line, but about holding a road, a passage, a supply chain, a critical dependency.
The world is still made of regions, but it operates by flow. This is perhaps the most important key to understanding our time. Those who only look at the borders still see the old map. Those who look at the flows begin to understand the new map.
And in this new map, Ormuz, Bab el-Mandeb, Suez, Malacca, submarine cables, fertilizers, semiconductors and data have become as many strategic places as capitals and borders.
Geopolitics is no longer played only where weapons are fired; it is also played where the world circulates.
