The US-Israeli Strike on Iran, the Death of Khamenei, and Strategic Implications for Singapore
March 2026
Executive Summary
On 28 February 2026, the United States and Israel launched an unprecedented joint military campaign — dubbed ‘Operation Epic Fury’ — against the Islamic Republic of Iran, resulting in the death of Supreme Leader Ayatollah Ali Khamenei, the elimination of senior military commanders, and the destruction of critical nuclear and defence infrastructure. Iranian state media confirmed Khamenei’s death in the early hours of 1 March 2026, triggering a 40-day mourning period and severe Iranian missile counter-strikes against Israel and multiple Gulf Arab states hosting US military assets.
This case study analyses the background, sequence of events, geopolitical outlook, and — critically — the multi-dimensional impact on Singapore, a small open economy deeply embedded in global trade, energy, and financial systems. It concludes with policy recommendations and strategic responses available to Singapore.
1. Case Study Background
1.1 Historical Context
Iran-US-Israel tensions have simmered for decades, rooted in the 1979 Islamic Revolution, Iran’s nuclear ambitions, and its sponsorship of regional proxy forces including Hezbollah, Hamas, and the Houthis. The past two years saw an accelerated deterioration: Israeli military campaigns dismantled significant portions of Iran’s proxy network, while a 12-day air war in June 2025 marked the first direct large-scale clash between Israeli and Iranian forces.
Following that June 2025 conflict, the US and Israel issued explicit warnings that further advances in Iran’s nuclear and ballistic missile programmes would trigger renewed strikes. Despite these warnings, Iran continued enrichment activities, setting the stage for the February 2026 campaign.
1.2 Immediate Triggers
Intelligence assessments in early 2026 indicated that Iran was within weeks of achieving sufficient fissile material for a nuclear device. Concurrently, the January 2026 domestic unrest — which resulted in thousands of deaths during a government crackdown — weakened the clerical regime’s internal legitimacy, presenting a perceived strategic window for regime destabilisation. These two factors converged to produce the joint decision to strike.

2. Geopolitical Outlook
2.1 Iran’s Political Transition
The death of Khamenei — who led Iran since 1989 — creates an unprecedented succession crisis. The CIA had assessed prior to the strikes that the Islamic Revolutionary Guard Corps (IRGC) would likely fill the power vacuum if Khamenei were killed. Three scenarios are plausible: (a) IRGC consolidation of power under a hardline military figure; (b) a fragmented struggle among clerical factions; or (c) a popular uprising exploiting the leadership vacuum, as encouraged by President Trump’s calls for Iranians to ‘take over your government.’
Each scenario carries distinct geopolitical consequences. An IRGC-dominated successor government may escalate conventional and proxy warfare. A fragmented regime could produce unpredictable nuclear security risks. A popular revolution, while optimal from a Western perspective, could take months or years to stabilise and may itself produce instability.
2.2 Regional Escalation Risks
Iran’s missile strikes against Gulf Arab states — including UAE, Bahrain, Qatar, and Kuwait — mark a significant escalation threshold, directly threatening US Fifth Fleet operations and Gulf Cooperation Council (GCC) stability. The closure of the Strait of Hormuz, through which approximately 20% of global oil consumption transits, constitutes an act of economic warfare with systemic global consequences.
Hezbollah, Hamas, and the Houthis — already severely weakened — may attempt to exploit the crisis with residual capabilities. The risk of miscalculation among multiple actors (Saudi Arabia, Turkey, Pakistan) is elevated.
2.3 US Domestic and Legal Dimensions
President Trump faces significant domestic political risk. Opposition Democrats and some Republican legislators have invoked the War Powers Act, arguing that a sustained campaign against Iran requires congressional authorisation. Failure to obtain such authorisation could constrain the operation’s duration and scope, potentially creating a window for Iranian reconstitution.
2.4 Global Energy and Economic Outlook
Analysts project an immediate oil price increase of US$10–20 per barrel upon market opening on 2 March 2026. Iran accounts for approximately 4% of global oil supply, and significantly more of Gulf-transit flows. Prolonged Strait closure would compound supply shocks. LNG flows from Qatar, a key global supplier, are also at risk. Global inflation pressures — already elevated — stand to worsen materially.
3. Impact on Singapore
| Singapore’s Strategic ExposureSingapore is acutely exposed to the Iran crisis across five dimensions: energy security, trade and shipping, financial markets, regional diplomatic positioning, and societal cohesion. As a small, open economy with no natural resources and one of the world’s busiest ports, Singapore has negligible margin for error in managing external shocks of this magnitude. |
3.1 Energy Security
Singapore relies almost entirely on imported energy, with approximately 95% of electricity generated from natural gas, a significant portion of which is sourced from or transported through the Gulf region. The closure of the Strait of Hormuz directly threatens LNG supply chains from Qatar and other Gulf producers. Even partial or temporary closure would trigger spot market price spikes, increase import costs for Singapore’s power generation sector, and risk pass-through to electricity tariffs for households and industries.
Petrochemicals represent a major pillar of Singapore’s manufacturing sector; upstream disruptions in Gulf crude supplies would cascade into refinery operations on Jurong Island, which processes substantial volumes of Middle Eastern crude. A sustained oil price surge would inflate Singapore’s energy import bill and compress margins across the petrochemical value chain.
3.2 Trade and Port Operations
The Port of Singapore, the world’s second-busiest by container throughput, handles transhipment cargo from the Middle East via routes that traverse the Gulf and Indian Ocean. Rerouting away from Gulf ports, aerial cargo diversions, and insurance surcharges for vessels operating in conflict-adjacent waters would increase operational costs and reduce throughput efficiency. Singapore Airlines (SIA), which operates a major hub at Changi Airport, would face route disruptions, fuel cost escalation, and potential airspace closures across the Middle East and South Asia corridors.
Singapore’s trade-to-GDP ratio exceeds 300%, making it among the world’s most trade-dependent economies. Any sustained contraction in global trade volumes — a plausible consequence of sustained Middle Eastern conflict — would disproportionately affect Singapore’s economic performance.
3.3 Financial Markets
Singapore hosts Asia’s largest foreign exchange trading centre and one of the world’s most active commodity derivatives markets. A sharp oil price spike would generate significant volatility across equities, currencies, and commodity futures. The Singapore dollar, which the Monetary Authority of Singapore (MAS) manages via an exchange rate-based monetary policy, faces potential depreciation pressure should risk-off sentiment dominate capital flows and commodity inflation trigger imported inflationary pressures.
Singapore’s wealth management sector, managing over SGD 5 trillion in assets under management, would face portfolio rebalancing pressures as global investors rotate away from risk assets into safe-haven instruments. The banking sector — particularly DBS, OCBC, and UOB — has limited direct exposure to Iran given existing sanctions regimes, but faces broader credit quality risks from increased counterparty stress in Gulf corporate and sovereign portfolios.
3.4 Diplomatic and Geopolitical Positioning
Singapore occupies a delicate diplomatic position as a non-aligned, multilateral-oriented city-state with deep ties to both the United States — its key security partner — and Arab Gulf states, which are important trading and investment partners. Singapore also maintains economic relations with Iran, primarily in the maritime and petrochemical sectors, albeit constrained by existing international sanctions.
The crisis tests Singapore’s principle of ‘active neutrality.’ Singapore will face pressure to publicly align with or distance itself from US-Israeli actions. Its consistent support for international law, UN processes, and the non-proliferation regime provides a principled framework, but the political dynamics require careful management to avoid alienating key partners.
Singapore’s Muslim-majority neighbours — Malaysia and Indonesia — are likely to express strong public condemnation of the US-Israeli strikes. This could create regional diplomatic tensions that Singapore, as a predominantly Chinese city-state in a Malay-Muslim majority region, must navigate with particular sensitivity.
3.5 Societal and Internal Security Dimensions
Singapore’s multi-racial, multi-religious society — including a Muslim community comprising approximately 14% of the population — requires careful domestic management during periods of heightened Middle Eastern conflict. Historical precedents, including the 2003 Iraq War, demonstrate the potential for community tensions to surface when Singapore is perceived to be insufficiently sympathetic to Muslim populations affected by Western military action.
The Internal Security Department (ISD) and the Community Engagement Programme (CEP) will likely be placed on heightened alert to monitor and counter any radicalisation narratives that external actors may seek to exploit. Social media disinformation campaigns targeting Singapore’s communal fabric represent an elevated risk in the current environment.

4. Policy Recommendations and Solutions for Singapore
4.1 Energy Resilience
In the immediate term, Singapore should activate its strategic petroleum reserve protocols and accelerate LNG spot procurement from non-Gulf suppliers, including Australia, the United States (Freeport LNG), and East African producers. The Energy Market Authority (EMA) should convene an emergency assessment of gas supply contracts and pipeline alternatives. Over the medium term, the crisis reinforces the strategic urgency of Singapore’s energy transition: accelerating solar deployment, regional power grid interconnection (ASEAN Power Grid), and hydrogen import infrastructure would reduce dependence on Gulf energy flows.
4.2 Trade and Port Diversification
The Maritime and Port Authority (MPA) should pre-position contingency routing plans for vessels currently transiting the Gulf. Singapore’s hub status makes it a natural beneficiary of Gulf trade diversion in the medium term, but short-term disruptions require active management. Engagement with shipping lines to ensure Singapore remains the preferred transhipment hub amid route changes is critical. Changi Airport should coordinate closely with SIA and regional carriers on overflight route adjustments, leveraging Southeast Asian airspace as a safer corridor.
4.3 Financial Market Stability
MAS should stand ready to deploy FX stabilisation operations should Singapore dollar volatility become disorderly. The existing Net Stable Funding Ratio and Liquidity Coverage Ratio requirements for Singapore-licensed banks provide a buffer, but supervisory stress testing for Gulf-connected portfolios should be expedited. The Government should also consider fiscal buffers — drawing on Reserves where necessary — to cushion household energy and cost-of-living impacts arising from oil price spikes.
4.4 Diplomatic Strategy
Singapore should reaffirm its commitment to the UN Charter, international law, and the nuclear non-proliferation regime as the principled basis for its public positions — neither explicitly endorsing nor condemning the strikes in binary terms. Engagement at the UN Security Council and General Assembly, consistent with Singapore’s strong multilateralist tradition, should emphasise de-escalation, humanitarian access in Iran, and the importance of a rules-based international order. Bilateral channels with Gulf Cooperation Council states, the United States, and ASEAN partners should be activated at the Ministerial level.
4.5 Community Resilience
The Government should pre-emptively engage religious and community leaders — particularly Islamic religious authorities — to promote inter-faith solidarity messaging and counter extremist narratives. The Online Safety Act’s provisions should be actively enforced against disinformation campaigns targeting Singapore’s communal landscape. Public communications should demonstrate Singapore’s humanitarian concern for civilians affected by the conflict, regardless of nationality or religion.
4.6 Business Continuity
The Economic Development Board (EDB) and Enterprise Singapore should issue guidance to MNCs and local enterprises on supply chain risk management, insurance cover reviews, and contingency sourcing strategies. Industries with direct Gulf exposure — petrochemicals, logistics, aerospace MRO — should be prioritised for government-to-business advisory outreach. Singapore’s investment promotion agencies should proactively reassure prospective investors that Singapore’s institutional strengths — rule of law, political stability, strategic location — are durable through global volatility events.
| Key Strategic InsightSingapore’s response to Operation Epic Fury will be a test of its foundational principles: sovereign pragmatism, multilateral engagement, social cohesion, and economic resilience. The crisis, while severe, also presents strategic opportunities — as a neutral hub, credible interlocutor, and safe harbour for capital, talent, and trade flows displaced by regional instability. |
5. Conclusion
The killing of Supreme Leader Khamenei and the broader Operation Epic Fury campaign represent the most significant rupture in Middle Eastern geopolitics since the 1979 Islamic Revolution. The immediate consequences — oil supply shocks, Strait of Hormuz closure, Gulf missile strikes, and Iranian political uncertainty — cascade through the global economic system with singular force on open economies like Singapore.
Singapore’s exposure is real and multi-dimensional: energy costs, port operations, financial market volatility, diplomatic positioning, and societal cohesion all face stress tests. However, Singapore’s institutional capacity, financial reserves, diplomatic credibility, and social resilience provide a strong foundation for navigating the crisis. The recommendations outlined in this paper — spanning energy diversification, financial stabilisation, diplomatic positioning, and community engagement — constitute a coherent and actionable response framework.
Ultimately, the crisis reinforces Singapore’s long-standing strategic logic: that small states must be perpetually prepared for external shocks they cannot control, by building resilience, maintaining relationships across divides, and consistently upholding the principles of international order that protect their sovereignty and prosperity.
