Singapore’s FM Warns Asia Faces ‘Crisis Moment’ as Iran War Chokes Energy Flows, Signaling Wider Economic Fallout

The economic shock from the war involving the United States and Iran is no longer confined to the Middle East. It is spreading outward with increasing impacts, unsettling energy markets, disrupting industrial supply chains, and raising the prospect of a broader global downturn.

At the center of that concern is the Strait of Hormuz, now effectively shut to normal traffic. The waterway carries about a fifth of the world’s oil and a large share of liquefied natural gas, making it one of the most critical chokepoints in the global economy.

“Right now the closure of the Strait of Hormuz is, in a sense, an Asian crisis,” Vivian Balakrishnan, Singapore’s foreign minister, told Reuters on Monday,

His warning reflects how heavily Asia depends on Middle Eastern energy, but it also points to a wider reality. The consequences are cascading far beyond the region.

Crude prices have surged past $100 a barrel, feeding directly into inflation across major economies. For Asia, which imports nearly 60% of its crude and petrochemical feedstocks from the Middle East, the impact is immediate. Refiners are cutting runs, petrochemical plants are scaling back operations, and some countries have moved to conserve domestic fuel supplies.

But the ripple effects are now being felt in Europe and North America as well. Higher energy costs are pushing up transportation, manufacturing, and food prices, reinforcing inflation at a time when central banks had been hoping to ease monetary policy. That shift is already altering expectations for interest rates, tightening financial conditions, and weighing on investment.

Balakrishnan did not mince words about the scale of the disruption. The conflict, he said, has left “the entire global economy” effectively exposed to a single geopolitical flashpoint.

The risk is not just the immediate loss of supply, but the potential for lasting damage. Donald Trump has threatened strikes on Iranian energy infrastructure, while Tehran has warned of retaliatory attacks across the Gulf.

“If indeed you get tit-for-tat destruction of energy infrastructure, then you’re dealing not only with an immediate blockage of the straits, but scarring of energy infrastructure from the Middle East,” Balakrishnan said.

That would extend the disruption well beyond the current crisis window, locking in higher prices and constraining supply for months, if not years.

Such a scenario would deepen what is already shaping into a difficult macroeconomic environment. Growth is slowing as energy costs rise, while inflation remains elevated. That combination limits the ability of policymakers to respond. Cutting rates risks fueling inflation further, while tightening policy to control prices could push economies closer to recession.

The concern is that what began as a regional conflict is now transmitting through the global economy via energy, trade, and financial channels.

Shipping costs are rising as insurers reprice risk in the Gulf. Supply chains are being rerouted, adding delays and costs. Energy-intensive industries, from chemicals to heavy manufacturing, are adjusting output. Each of these shifts adds friction to an already strained global system.

Asia remains the most exposed. Around 80% of oil passing through the Strait of Hormuz is destined for the region, leaving economies such as China, India, Japan, and South Korea particularly vulnerable.

“The vulnerability has been known, but it’s never been tested to the extreme that it is being tested today,” Balakrishnan said.

Yet the broader implication is that no major economy is insulated. The United States may be a net exporter of oil, but it is not immune to global price dynamics. Higher crude prices feed into domestic fuel costs and industrial inputs, while also influencing inflation expectations.

The comparison with past crises is beginning to surface. While Balakrishnan said it is too early to conclude that the situation will mirror the 1997 Asian financial crisis, the fact that governments are revisiting contingency frameworks from that period underscores the level of concern.

Singapore, a trade-dependent hub, is preparing across multiple time horizons, from immediate disruptions measured in hours to structural adjustments over years. The approach centers on maintaining fiscal stability, strengthening supply chains, and positioning itself as a predictable node in an increasingly volatile system.

“In the state of the world now, some stability, some predictability, some safety, will be a welcome bright spot in an otherwise difficult, volatile world,” Balakrishnan said.

The crisis is also accelerating longer-term shifts. Governments across Asia are expected to double down on energy diversification, expand renewable capacity, and invest in infrastructure that reduces reliance on vulnerable transit routes. Those efforts, however, will take time.

In the near term, the trajectory of the conflict will determine the depth of the economic impact. Balakrishnan expressed regret at how events unfolded.

“I will confess that I was surprised with the onset of hostilities. I didn’t think it was necessary. I don’t think it’s helpful, and even now, there are even doubts expressed about the legality of the situation,” he said.

For many countries, the frustration lies in bearing the economic consequences of a conflict they do not control.

The longer the disruption to the Strait persists, the more entrenched its effects will become. What began as a geopolitical confrontation is evolving into an economic test, and it is exposing the fragility of global energy flows and how much economies are tied to them.
