The sea, although invisible on most economic maps, exerts a deep and direct influence on the functioning of the global economy. Strategic maritime points—such as the strait of Ormuz, the Bab-el-Mandeb strait, and the Panama Canal—are not only vital transit routes for global trade, but in certain cases, can become tools of geopolitical power. The blockade of Ormuz and tensions in Bab-el-Mandeb and the Panama Canal have revealed the fragility of the global trade system, showing how a maritime action can trigger broad economic consequences, including inflation and a realignment of international influence.
Blockade of Ormuz: A Critical Point in Global Trade
Ormuz, an island located in the Persian Gulf, is one of the most strategic points in the world for maritime trade. It is the only passage allowing oil from the Persian Gulf to reach the rest of the world. Each year, over 20 million barrels of oil pass through the Ormuz Strait, making it a vital axis for global energy supply. In 2026, a partial blockade of this passage, caused by tensions between Iran and Saudi Arabia, generated a significant disruption in crude oil flow. Although no total blockade occurred, traffic decreased by 30 percent in the first weeks of October, according to data from the International Institute of International Trade Studies (IECI).
The impact was reflected in derivative markets. Fuel inflation rates in Asia and Europe increased by 1.2 percent during that period. Spanish Bank analysts note that although the blockade did not cause an energy crisis, it did trigger a surge in the prices of petroleum-derived products, affecting sectors such as the automotive industry and logistics.
Bab-el-Mandeb Strait: A Key Passage Between the Mediterranean and the Indian Ocean
The Bab-el-Mandeb Strait, connecting the Red Sea with the Indian Ocean, is another critical point in the global trade system. Each year, over 12,000 ships pass through this passage, transporting goods such as food, medicines, and raw materials. In 2026, incidents of confrontation between Egyptian and Saudi security forces occurred in the context of a dispute over control of maritime routes in the southern Red Sea.
These incidents, although they did not result in a direct blockade, generated uncertainty among shipping operators. According to the United Nations' Maritime Safety Center report, the average waiting time for vessel transit increased by 15 percent, which raised logistical costs. Moreover, transport companies began evaluating alternatives, such as using longer routes, which on average increased transportation costs by 8 percent.
The UN has warned that if tensions intensify at this point, a shortage of key products could emerge, especially in countries that rely on food and medicine supplies from the Indian Ocean.
The Panama Canal: a global connectivity hub
The Panama Canal, one of the world's major maritime passages, allows over 14,000 ships annually to pass, connecting the Atlantic and Pacific Oceans. In 2-than, technical problems were reported in the canal's facilities due to a failure in its automated navigation system. Although a full closure did not occur, disruptions of up to 48 hours were reported in certain sections of the passage.
These disruptions particularly affected shipping routes between the United States and Asia, where transportation costs increased by 10 percent. The North American Maritime Transport Association (ATMAN) indicated that over 300 container transit delays were recorded in early October, which created pressure on imported goods prices in North America.
The technical issue was attributed to a software update that was not fully tested before implementation. Maritime infrastructure experts point out that this incident highlights the dependence of critical operations on digital systems, and that any failure could have wide-ranging economic consequences.
The global trade vulnerability to strategic actions
The three points mentioned—Ormuz, Bab-el-Mandeb, and Panama—are not merely transit routes, but strategic control points. Any action affecting their operation—whether a blockade, tension, or technical failure—could destabilize the global flow of goods and services. This vulnerability has become more evident in a world where international trade increasingly depends on maritime routes controlled by states or regional groups.
The World Bank published a report in 2026 indicating that 70 percent of global trade is conducted by sea. This means that any disruption at these strategic points can have a direct impact on inflation, product availability, and the economic stability of countries that rely on imports.
Moreover, the impact is not limited to goods markets. Financial markets also react to events at sea. For example, in October 2026, the global market volatility index increased by 12 percent following the partial blockade of Ormuz, reflecting the financial markets' sensitivity to maritime events.
Implications for inflation and the global economy
Rising transportation costs and delays in cargo transit have a direct effect on inflation. When products become more expensive due to logistical issues, consumers pay more, leading to price increases in consumer goods. In the case of Ormuz, the rise in fuel prices affected sectors such as food and energy, which was reflected in inflation indices in countries like India, Turkey, and Mexico.
Regarding the Bab-el-Mandeb Strait, medication shortages in southern African countries were notable. According to Egypt's Ministry of Health, the delivery time for key medications increased by 25 percent, putting at risk access to critical treatments.
As for the Panama Canal, it affected the supply chain of electronic products in North America. Technology companies reported increased production costs due to shortages of components imported from Asia, which translated into higher prices for consumers.
The pulse of global hegemony
Maritime strategic points do not only affect trade, but have also become arenas of geopolitical competition. Countries that control these routes—such as Saudi Arabia, Egypt, the United States, or China—can use them as tools to influence global trade, pressure other actors, or even impose indirect economic sanctions.
In 2026, an intensification of competition between the United States and China in controlling maritime routes was observed. The United States has strengthened its presence in the Persian Gulf, while China has increased its investment in maritime infrastructure in the Indian Ocean. This competition not only affects trade, but may also trigger a race for maritime dominance.
Experts in international politics point out that, in an increasingly interconnected world, control of the seas is not merely a matter of security, but of economic power. Whoever controls maritime routes controls the flow of global wealth.
Future perspectives and recommendations
To mitigate the risks associated with maritime routes, several solutions have been proposed. Among them, the strengthening of alternative routes, such as the Suez Canal or the Malacca Strait, which could be used as backup in case of blockages. Additionally, it is recommended to establish international coordination mechanisms to manage tensions at strategic points.
The United Nations Working Group on Maritime Routes has proposed an early warning system that would allow countries to coordinate their actions in response to events that could affect transit. This system, still in development, could be key to preventing economic crises resulting from maritime disruptions.
Finally, it is considered that diversifying transportation routes, together with investment in more robust navigation technologies, could reduce dependence on a single strategic route. This would not only protect global trade, but also strengthen the economic resilience of the most vulnerable countries.
