A leading global financial advisory chief has warned that markets preoccupied with the Strait of Hormuz risk overlooking a more consequential vulnerability now taking shape at the world’s busiest shipping chokepoint.
Nigel Green, chief executive of deVere Group, says what he terms the “Malacca Premium” is already crystallising, reflecting the rising cost of insuring, shipping, and moving energy through a corridor that global commerce has long treated as predictable and open.
The Strait of Malacca, a narrow waterway running between Indonesia and Malaysia and funnelling trade past Singapore, carries more than a fifth of global maritime commerce. In the first half of 2025, more than 23 million barrels of oil moved through the route daily, supplying the energy needs of China, Japan, and South Korea. The volume leaves virtually no buffer for disruption without triggering global consequences.
“The Malacca Premium is coming at us in real time. Markets are under-pricing how quickly disruption in one chokepoint can ripple through the entire system,” Green said.
Concern sharpened when a senior Indonesian official briefly floated the idea of imposing transit tolls on vessels using the strait in the wake of the Hormuz disruption. The proposal was quickly withdrawn, with regional governments reaffirming that passage would remain open and unrestricted. The episode lasted days. Its effect on market thinking outlasted its withdrawal.
“The fact that tolls were even mentioned tells you everything about how the risk profile is changing,” Green said. “This is no longer just about physical disruption. It is about political leverage and how quickly assumptions can be challenged.”
The strait operates under international rules guaranteeing transit passage. Green argues, however, that legal frameworks do not neutralise geopolitical exposure. Global trade has been engineered around the assumption of uninterrupted flow through a handful of narrow corridors, and that assumption is now under measurable strain.
Shipping insurance, freight rates, and energy pricing are already responding. Even a signal of potential disruption, without any physical blockage, can move quickly through supply chains given the daily density of traffic transiting the route.
China’s long-standing concern over its dependence on the waterway, a strategic vulnerability Beijing has historically called the “Malacca Dilemma,” adds further weight. As the world’s largest oil importer, any instability affecting the corridor carries consequences that extend well beyond Southeast Asia.
For investors, Green says the implications are immediate. Businesses with pricing flexibility and alternative routing capacity are better positioned as risk is repriced. Those exposed to seamless, low-cost global logistics face growing fragility.
“What the market hasn’t done is price fragility properly,” he said. “The Malacca Premium is that repricing, and it’s unlikely to be gradual if conditions deteriorate.”
Disruption does not need to materialise at scale to move markets. Anticipation alone, expressed through rising insurance costs, higher freight rates, and energy price volatility, is already beginning to reshape returns across global portfolios.
