Global markets remain fixated on disruption in the Strait of Hormuz. That focus is understandable, but it risks missing a more consequential vulnerability now coming into view, warns Nigel Green, CEO of financial advisory giant deVere Group.
What he describes as the “Malacca Premium” is now capturing the rising cost of insuring, shipping, and moving energy through one of the world’s most critical trade corridors.
The Strait of Malacca, a narrow waterway between Indonesia and Malaysia that channels trade past Singapore, handles over a fifth of global maritime commerce and ranks as the world’s busiest chokepoint.
“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,” comments Nigel Green.
In the first half of 2025 alone, over 23 million barrels of oil per day passed through the route, supplying China, Japan, and South Korea. The volume leaves little room for disruption without global consequences.
Concern has intensified because of how quickly the narrative around Malacca changed. In the wake of disruption in Hormuz, a senior Indonesian official briefly raised the possibility of introducing transit tolls for vessels using the strait before the idea was swiftly withdrawn and regional governments reaffirmed that passage would remain open and free.
The signal, however, has already shifted market thinking.
“The fact that tolls were even mentioned tells you everything about how the risk profile is changing,” says the deVere CEO.
“This is no longer just about physical disruption. It’s about political leverage and how quickly assumptions can be challenged.
“The strait operates under international rules guaranteeing transit passage, yet markets are now confronting a more uncomfortable reality: legal protections do not eliminate geopolitical risk.”
Global trade remains heavily concentrated through a handful of narrow corridors. The assumption of uninterrupted flow through these arteries has underpinned decades of efficiency gains.
“The assumption is now under strain—and the intensifying Malacca Premium reflects the cost.”
Shipping insurance, freight rates, and energy pricing are already responding to rising sensitivity. Even minor disruptions or policy signals can ripple quickly through supply chains, given the density of traffic moving through the corridor.
“The market has spent years optimising for efficiency,” Nigel Green says.
“What it hasn’t done is price fragility properly. The Malacca Premium is that repricing—and it’s unlikely to be gradual if conditions deteriorate.”
The implications for investors are immediate. “Exposure to seamless, low-cost global logistics is becoming more fragile, while businesses with flexibility, pricing power and alternative routing capability are better positioned as risk is repriced.”
Disruption does not need to materialise at scale to move markets. The anticipation alone—through insurance costs, freight rates and energy volatility—is enough to reshape returns.
China’s long-standing concern over reliance on the Malacca Strait, often referred to as the “Malacca Dilemma”, adds further weight.
As the world’s largest oil importer, it amplifies the global consequences of any instability in the corridor.
Nigel Green concludes: “Investors need to understand the speed at which this risk can escalate.
“The Malacca Premium is taking shape now. If this corridor comes under sustained pressure, the impact on global trade, energy markets and asset prices could be immediate and significant.
“I suspect that the Malacca Premium, which is taking shape now, is likely to become a defining force in global trade and markets.”
