When the first missiles struck Tehran in the pre-dawn hours of 28 February 2026, the tremors were felt not only across the Middle East but along the trading arteries of Southeast Asia. For Singapore — a city-state whose existential architecture is built on the free flow of trade, energy, and capital — the joint US–Israeli operation codenamed Roaring Lion / Operation Epic Fury is not a distant geopolitical abstraction. It is an acute economic and strategic stress test arriving at a moment of already elevated global fragility.
The strike, which killed Iranian Supreme Leader Ali Khamenei and targeted military command infrastructure across Iran, instantly triggered retaliatory missile and drone attacks on US military installations in Bahrain, Qatar, Kuwait, and the UAE. Iran’s Islamic Revolutionary Guard Corps simultaneously moved to functionally close the Strait of Hormuz — the 21-mile-wide chokepoint through which roughly 20 percent of the world’s daily oil supply and 20 percent of global liquefied natural gas (LNG) exports transit. Major shipping firms including Maersk and Hapag-Lloyd suspended all Strait transits. Oil tankers fell silent at anchor. For an island republic that imports virtually all of its energy needs and whose port ranks among the world’s busiest, the convergence of these events constitutes a multidimensional emergency.
I. SINGAPORE’S DIPLOMATIC POSTURE: PRINCIPLED BUT EXPOSED
Singapore’s Ministry of Foreign Affairs responded with characteristic precision on the evening of 28 February. In a statement that carefully threaded diplomatic needles, the MFA said Singapore ‘regrets the failure of negotiations’ that produced the strikes, urged all parties ‘to return to negotiations to achieve a peaceful resolution in accordance with international law and the principles of the UN Charter,’ and advised all Singaporeans to defer travel to Israel, Iran, and the wider Middle East region.
The language was deliberate and revealing. Singapore did not condemn the strikes. It did not endorse them. It did not invoke Israeli self-defence arguments as Canada did, nor did it echo Norway’s legal critique that ‘preventive attacks require an immediately imminent threat.’ Singapore’s formulation — regretting the failure of diplomacy — places the emphasis on process rather than attribution, consistent with the Republic’s longstanding position of non-alignment on major-power disputes.

This posture reflects a structural reality that constrains Singapore’s room for manoeuvre: the Republic depends on US security guarantees for regional stability while simultaneously requiring unobstructed Middle East energy flows and deep trade integration with China, which receives half of its crude imports through the Strait. Publicly aligning with either camp risks rupturing relationships that Singapore cannot afford to lose.
The diplomatic balancing act carries domestic political weight as well. Singapore’s Muslim community — comprising roughly 15 percent of the population — will be watching governmental responses closely, particularly given Iranian President Pezeshkian’s framing of Khamenei’s killing as ‘a declaration of open war on Muslims.’ Singapore’s leaders will need to speak with exceptional care to a population that spans the full spectrum of views on the conflict.
II. THE ENERGY CHOKEPOINT: IMMEDIATE AND STRUCTURAL RISKS
Singapore is an almost pure energy importer. The Republic has no domestic oil or gas production of any consequence. Its refining complex at Jurong Island — among the largest in Asia — processes crude primarily sourced from the Gulf. Any sustained disruption to Strait of Hormuz transit translates directly into higher input costs for Singaporean refiners, elevated domestic fuel prices, and potential pass-through inflation across the economy.
The scale of the Hormuz disruption is without modern precedent. Approximately 20 million barrels of oil pass through the strait daily, according to the US Energy Information Administration. About 84 percent of crude transiting the strait is destined for Asian markets. Singapore, as a major refining and trading hub, sits at the centre of this supply architecture. Vandana Hari, chief executive of Singapore-based energy consultancy Vanda Insights, projected oil prices would jump to $80 per barrel if the conflict persisted through the opening of Monday’s markets — a significant premium over the $73 Brent close on Friday. Analysts at UOB Kay Hian warned of scenarios approaching $100 per barrel in a protracted war.
The LNG dimension compounds the risk. Qatar, which supplies roughly a fifth of global LNG through the Strait, has been struck by Iranian retaliatory missiles. Singapore’s Pavilion Gas and other domestic distributors source significant volumes from Qatar. Any sustained disruption to Qatari LNG exports would tighten Asian spot markets dramatically, raising electricity generation costs and potentially triggering supply management measures by SP Group and EMA. Unlike crude, LNG cannot simply be rerouted around Africa without enormous cost and delay penalties — LNG vessels are purpose-built and route-specific in ways that crude tankers are not.
The Hormuz partial closure also raises marine insurance costs instantly. Lloyd’s of London market sources reported dramatic premium increases and war-risk notice activations within hours of the strikes. Higher insurance costs feed directly into shipping freight rates, affecting not just energy but the broader basket of goods — chemicals, plastics, steel, electronics components — that flow between the Gulf and Singapore’s manufacturing and re-export sector.
III. SINGAPORE AS PORT AND TRADING HUB: PARADOX OF DISRUPTION
There is a paradox embedded in the Hormuz crisis for Singapore’s port economy. On one hand, disruption that forces tankers to reroute around Africa’s Cape of Good Hope adds approximately 10 to 14 days and 3,500 nautical miles to a Gulf–Asia journey. This ties up global fleet capacity by an estimated 12 to 15 percent and could generate significant congestion at transshipment hubs. Singapore’s PSA, already operating at high throughput, could face vessel queuing and scheduling disruption as rerouted ships compete for berths.
On the other hand, Singapore has historically benefited from being a neutral, stable, deepwater entrepôt during periods of regional turbulence. If Middle Eastern ports are degraded or rendered unusable — as Iranian strikes on UAE facilities have already begun to do — Singapore becomes more, not less, strategically important as a transshipment node for Asian trade that formerly moved through Dubai or Jebel Ali. The question is whether this secondary benefit can meaningfully offset the energy cost shock.
The aviation dimension adds further complexity. Singapore Airlines and low-cost subsidiary Scoot cancelled 26 flights to the Middle East between 28 February and 7 March, including daily Dubai services SQ494 and SQ495 and the Jeddah routes TR596/TR597. SIA noted that ‘as the situation remains fluid, other SIA flights may be affected.’ Dubai International Airport — the world’s busiest international hub — has suspended operations indefinitely. For Singapore Airlines, the Dubai route is a critical transit point for onward connections to Europe and Africa. Prolonged closure amplifies SIA’s operational costs through longer diversionary routing and erodes load factors on one of its most commercially valuable corridors.
IV. FINANCIAL MARKETS: SINGAPORE AS ASIAN RISK BAROMETER
Singapore’s financial sector will face acute pressure when Asian markets open on Monday. The Straits Times Index, highly sensitive to global sentiment given Singapore’s role as a financial gateway, will be watched closely. Kenneth Goh, director of private wealth management at UOB Kay Hian in Singapore, told CNBC that the conflict represents categorically different market risk from prior episodes: ‘Venezuela was a production story. Iran is a chokepoint story.’ The implication is that past market playbooks — where brief spikes in oil prices subsided once the Strait proved open — may not apply.
The Singapore dollar, which tends to act as an Asian safe-haven currency in periods of emerging-market stress, will face competing pressures. A flight to the US dollar and Japanese yen — as Goh predicted — would typically weaken the SGD against the greenback, but Singapore’s Monetary Authority typically uses exchange-rate policy as an anti-inflation tool. If oil prices spike materially, MAS may be compelled to reassess its SGD nominal effective exchange rate (NEER) slope to dampen imported inflation.
Banks heavily exposed to trade finance and commodity hedging — DBS, OCBC, and UOB — face elevated counterparty risk from clients in the energy and shipping sectors. Trade finance volumes through Singapore are enormous; any tightening of credit availability as risk premiums rise will cascade through the SME exporters and commodity traders that form a significant part of Singapore’s economic substrate.
V. GEOPOLITICAL RECALIBRATION: THE US ALLIANCE AND ASEAN MULTILATERALISM
The strikes raise deeper questions about Singapore’s strategic alignment that will play out over months and years rather than days. The US–Israel operation was conducted without congressional authorisation, drawing immediate demands for war powers legislation from members of the US Senate and House. For Singapore, which maintains robust defence cooperation with Washington — including access arrangements at Sembawang port and Paya Lebar Air Base — the conflict creates a form of institutional exposure.
Singapore has long insisted that it does not choose sides between major powers, a posture encapsulated in the oft-cited formulation that Singapore seeks good relations with all major powers without being against any. But the current conflict, which directly involves US military action, tests the limits of that neutrality. If Iranian proxies or state actors perceive Singapore’s ports or logistics infrastructure as part of US power projection architecture — however indirectly — the Republic’s non-combatant status cannot be taken for granted.
Within ASEAN, Singapore will need to coordinate carefully. Indonesia — the chair of the G20 in 2026 and home to the world’s largest Muslim population — swiftly offered to mediate the US–Iran conflict through its embassy. Malaysia’s government faces strong domestic pressure to denounce the strikes unequivocally. Singapore’s measured diplomatic language may come under pressure from neighbours who read the region’s Muslim publics more directly.

VI. THE NUCLEAR AFTERMATH: STRATEGIC UNCERTAINTY
Paradoxically, the destruction of Iran’s nuclear programme — one of the stated US objectives — may produce a period of strategic uncertainty more dangerous than a constrained nuclear Iran. With Khamenei dead and the Islamic Republic under existential military pressure, the succession question is acute. Iran has declared 40 days of mourning and the government of President Pezeshkian has called revenge its ‘legitimate right and duty.’ A fragmented Iranian leadership competing for post-Khamenei authority may prove less predictable than the centralised theocracy it replaces.
For Singapore’s long-term energy planning, the disruption to Gulf stability accelerates pre-existing imperatives around energy diversification. The Jurong Island refining complex and Singapore’s LNG terminal at Jurong Island already source from multiple non-Gulf origins, but the concentration of exposure to Hormuz-dependent supply remains significant. A sustained conflict lasting weeks or months would provide renewed urgency to energy storage expansion, alternative supply contracting with Australian LNG producers, and potentially to accelerated planning for the nuclear energy pathway that Singapore’s government has begun studying more seriously in recent years.
VII. CONCLUSION: RESILIENCE ARCHITECTURE UNDER STRESS
Singapore has survived existential economic shocks before — the oil crises of 1973 and 1979, the Asian financial contagion of 1997, the SARS epidemic of 2003, and the global financial crisis of 2008. Each tested the Republic’s institutional resilience and forced adaptive recalibration. The US–Israel war on Iran presents a compound shock: energy supply disruption, shipping rerouting costs, aviation network degradation, financial market volatility, diplomatic triangulation pressure, and a broader reconfiguration of Middle Eastern regional order — all arriving simultaneously.
What distinguishes Singapore’s position in 2026 is not vulnerability per se — the Republic has always been vulnerable, and its leadership has always known it. What distinguishes the moment is the degree to which the international rules-based order that Singapore has championed and depended upon is visibly strained. The strikes were conducted before diplomatic options were exhausted — Oman’s foreign minister had announced a breakthrough just 24 hours before the missiles flew. The UN Charter principles that Singapore invoked in its MFA statement appear aspirational rather than operative.
Singapore’s response will need to be multi-track: diplomatic engagement at the UN and ASEAN to push for de-escalation; energy security activation through IEA mechanisms and bilateral supply diversification; financial stability measures coordinated between MAS and the major banks; consumer price monitoring by MTI and EDB; and proactive communication to Singaporeans about the economic outlook. The government has managed crises of this complexity before. The test now is whether Singapore’s institutions, reflexes, and relationships are adequate to a conflict that — unlike past regional shocks — has no clear offramp and no precedent for its combination of variables.
For the protesters marching on US and Israeli embassies in Athens, Singapore’s hedged diplomacy may appear morally insufficient. But for a small, open, trade-dependent city-state of 5.9 million people sitting at the intersection of global supply chains, the logic of strategic restraint is not cowardice — it is the arithmetic of survival.
