Chokepoint at Risk: How the Taiwan Crisis Could Jam the Malacca Strait
The Malacca Strait remains one of the world’s most critical maritime corridors, with approximately 94,000 ships transiting annually, accounting for about 30% of global trade . For East Asian economies—particularly China, Japan, and South Korea—the strait is indispensable. Notably, 80% of China’s oil imports, constituting 60% of its total oil supply, traverse this route. Such figures underscore the strait’s strategic importance in global energy and trade networks.
The Taiwan Strait is another pivotal maritime passage, with nearly 50% of the world’s 5,400 container ships passing through in 2022 . Escalating tensions between China and Taiwan raise concerns about potential disruptions. A conflict could severely impede maritime and aerial routes in and around Taiwan, leading to significant rerouting of shipping traffic . Such disruptions would likely divert vessels to alternative routes like the Malacca Strait, exacerbating congestion and increasing risks associated with piracy and logistical delays.
A prolonged crisis of the Taiwan Strait could lead to a substantial increase in shipping costs due to rerouting and heightened insurance premiums. For Malaysia, where trade accounted for approximately 131.84% of GDP in 2023 , such disruptions could have profound economic implications. In the semiconductor sector, Malaysia exported $12.7 billion worth of semiconductor devices in 2023, with significant exports to the United States, China, and Germany . Any interruption in supply chains, especially from China’s manufacturing hubs, could adversely affect Malaysia’s export-driven economy.
In addition, energy markets would feel the shock. With global oil transport so heavily reliant on uninterrupted traffic through the Malacca Strait, any slowdown or closure would likely result in a sharp spike in oil prices. In fact, during a regional geopolitical flare-up in 2022, global oil prices surged by 35%, demonstrating just how sensitive energy markets are to maritime instability in this corridor.
The China-Taiwan crisis, while seemingly distant for many, holds direct and immediate consequences for global trade, particularly through the Malacca Strait. The disruption of this critical maritime route could result in higher shipping costs, delayed supply chains, and volatile fuel prices, with serious economic repercussions for Malaysia and the broader Southeast Asian region. As tensions rise, it becomes increasingly apparent that the international community must prioritize diplomatic solutions to prevent further destabilization. For countries like Malaysia, the balance between geopolitical neutrality and economic resilience will be essential in navigating the complex challenges ahead.
