Conflict Onset: 28 February 2026 • Case Study Date: 2 March 2026
Prepared for Academic and Policy Analysis
Executive Summary
On 28 February 2026, the United States and Israel initiated coordinated strikes against Iran, triggering open armed conflict. Within 72 hours, the United States had sunk nine Iranian warships, struck Iran’s naval headquarters, and deployed B-2 stealth bombers against underground missile facilities. Iran retaliated with hundreds of missile and drone attacks, resulting in the first confirmed deaths of US servicemembers. Three US personnel were killed and five seriously wounded as of 1 March 2026.
Singapore, as one of the world’s most trade-dependent open economies, is acutely exposed to the cascading consequences of this conflict. This case study examines Singapore’s vulnerabilities across five domains: energy security, trade and supply chain disruption, aviation and logistics, financial market contagion, and broader geopolitical positioning. It concludes with policy implications and scenario projections.
1. Background and Conflict Context
1.1 Sequence of Events
The conflict escalated rapidly from a pre-existing state of heightened US-Iran tension to full-scale military operations within hours of the first strikes on 28 February 2026. Key milestones in the first 72 hours are summarised below.
| Date/Time (SGT) | Event | Strategic Significance |
| 28 Feb 2026 | US and Israel conduct coordinated air strikes on Iran | Escalation to open armed conflict; crossing of deterrence threshold |
| 28 Feb 2026 | Iran retaliates with missiles and drones against Gulf targets | Dubai’s Palm Jumeirah struck; Qatar affected; regional escalation confirmed |
| 1 Mar 2026 | US B-2 bombers strike underground Iranian missile facilities | Signals intent to degrade Iran’s long-range strike capability; potential nuclear dimension |
| 1 Mar 2026 | Nine Iranian warships destroyed; naval HQ struck | US seeks to neutralise Iranian ability to close the Strait of Hormuz |
| 1 Mar 2026 | First 3 US servicemember deaths confirmed; 5 seriously wounded | Domestic political pressure on US to escalate or negotiate |
| 2 Mar 2026 | Trump announces intent to sink remainder of Iran’s fleet | Suggests conflict will intensify; no diplomatic off-ramp visible |
1.2 Geopolitical Stakes
The Strait of Hormuz, through which approximately 20% of global oil and liquefied natural gas (LNG) transit, is Iran’s primary lever of economic coercion. Even a partial closure or disruption of shipping lanes would have immediate and severe consequences for global energy markets. Singapore’s position as a major refining and trading hub for petroleum products in Asia amplifies its exposure.
2. Energy Security Impact
2.1 Oil Price Volatility
Singapore imports virtually all of its energy requirements. While the country has diversified its import sources over the decades, crude oil from the Middle East remains a substantial component of refinery feedstock for Singapore’s integrated refining and petrochemical complex on Jurong Island, one of the largest in the world.
Short-term price impacts are already visible. Conflict-driven supply-side uncertainty typically triggers an immediate risk premium in Brent crude, historically ranging from USD 5-20 per barrel in analogous episodes (e.g., Gulf War I, Iranian tanker attacks in 2019). An extended conflict involving Hormuz disruption could push prices substantially higher.
| Scenario | Duration of Conflict | Estimated Oil Price Range (USD/bbl) | Singapore Inflation Impact |
| Base Case | < 2 weeks, no Hormuz disruption | $85 – $105 | Minimal; < 0.3 pp CPI |
| Moderate Escalation | 2–8 weeks, partial shipping disruption | $105 – $140 | Moderate; 0.5–1.2 pp CPI |
| Severe Escalation | > 8 weeks, Hormuz effectively blocked | $140 – $200+ | Severe; 1.5–3.0 pp CPI |
| Catastrophic | Full Hormuz closure, US-Iran naval war | $200+ | Crisis-level; demand destruction, recession risk |
2.2 LNG Supply Chains
Singapore has emerged as a regional LNG hub, with the Jurong Island LNG terminal receiving cargoes from Qatar and other Gulf producers. Qatar, which borders the Gulf and was itself affected by Iranian retaliatory strikes, is among the world’s largest LNG exporters. Any disruption to Qatari LNG production or export capacity would tighten Asian LNG markets, driving up electricity generation costs in Singapore and across the region.
The Ministry of Trade and Industry and the Energy Market Authority are expected to monitor LNG spot prices and activate strategic reserve provisions if supply tightens significantly.
3. Trade, Supply Chain, and Logistics Disruption
3.1 Shipping Route Vulnerability
Singapore’s port, consistently ranked among the world’s busiest, serves as a critical transshipment hub for cargo moving between Asia, the Middle East, and Europe. The primary shipping artery connecting Singapore to the Gulf traverses the Indian Ocean and enters the Arabian Sea en route to the Strait of Hormuz. Any militarisation of these waters — through mine-laying, anti-ship missile threats, or direct naval confrontation — would force re-routing via the Cape of Good Hope, adding approximately two to three weeks of transit time and significantly increasing freight costs.
3.2 Effects on Key Trade Partners
Singapore’s trade exposure to the affected region extends beyond direct bilateral flows. Several of Singapore’s key manufacturing and consumer markets — including India, South Korea, Japan, and China — are themselves heavily dependent on Gulf energy. A broader economic slowdown in these countries would reduce demand for Singapore’s exports of electronics, chemicals, and financial services.
| Trade Partner | Exposure to Gulf Energy | Risk to Singapore Exports |
| Japan | ~90% oil import dependence on Middle East | Reduced demand for petrochemicals; yen volatility |
| South Korea | ~75% oil import dependence on Middle East | Slowdown in electronics and shipbuilding; FX pressure |
| India | ~60% oil import dependence on Middle East | Inflationary pressure; reduced consumer demand |
| China | ~45% oil import dependence on Middle East | Manufacturing cost increases; strategic stockpiling |
| European Union | Moderate, via LNG and pipeline alternatives | Reduced trade finance activity through Singapore |
4. Aviation and Tourism Disruption
4.1 Flight Cancellations and Airspace Closure
Singapore Airlines (SIA) and its low-cost subsidiary Scoot had cancelled 26 flights to and from the Middle East as of 2 March 2026, with further cancellations expected as the conflict persists. The affected routes include Singapore-Dubai, Singapore-Doha, and Singapore-Abu Dhabi — among SIA’s highest-yield long-haul routes.
Beyond direct cancellations, the conflict has the potential to close large sections of Iranian, Iraqi, and Gulf airspace, forcing longer re-routing for European and Middle Eastern services. This increases fuel burn, disrupts crew scheduling, and reduces the frequency with which aircraft can be cycled, compressing airline margins at a time of already thin post-pandemic recovery.
4.2 Tourism and MICE Sector
Singapore is a significant destination for Gulf-based business travellers and tourists. Disruption to direct air connectivity, combined with economic uncertainty among high-net-worth Gulf residents, is likely to reduce inbound tourism from the region. The MICE (meetings, incentives, conferences, and exhibitions) sector, which Singapore has heavily invested in, may also see cancellations from Gulf-state delegations and corporate clients.
5. Financial Markets and Monetary Policy Implications
5.1 Equity and Currency Markets
The Singapore Exchange (SGX) is expected to face headwinds from geopolitical risk aversion. Regional equity markets typically experience a flight to safety during Middle East conflicts, with capital moving into the US dollar, gold, and other safe-haven assets. The Singapore dollar (SGD), while generally regarded as a regional safe-haven currency itself, may face modest depreciation pressure if risk-off sentiment dominates Asian markets broadly.
The Monetary Authority of Singapore (MAS) conducts monetary policy through the exchange rate rather than interest rates, managing the SGD nominal effective exchange rate (NEER) within an undisclosed policy band. Inflationary imported energy costs may prompt MAS to maintain or tighten its exchange rate policy stance to offset price pressures, even as global growth risks rise.
5.2 Banking and Financial Services Exposure
Singapore’s three major banks — DBS, OCBC, and UOB — have varying degrees of exposure to Gulf counterparties and Gulf-based financing for regional trade. Letters of credit, trade finance facilities, and commodity financing operations could be disrupted if Gulf-based correspondent banks face liquidity stress or sanctions-related complications.
The Islamic finance segment, in which Singapore has invested institutional capital to position itself as a hub, may also face market volatility, given the concentration of Islamic finance assets in GCC jurisdictions directly affected by the conflict.
6. Geopolitical and Strategic Positioning
6.1 Singapore’s Foreign Policy Constraints
Singapore occupies a structurally delicate position in international affairs. As a small state with vital interests in the rule of international law and freedom of navigation, Singapore has consistently advocated for the peaceful resolution of disputes and the inviolability of shipping lanes. The open armed conflict between two major powers or power blocs creates pressure on Singapore to signal solidarity with its security partners — including the United States, with whom Singapore maintains a significant defence cooperation arrangement under the 1990 MOU — while preserving economic and diplomatic relationships with regional Muslim-majority states and with Iran’s major trade partners, particularly China.
6.2 ASEAN Solidarity and Regional Diplomacy
ASEAN, of which Singapore is a founding member, operates by consensus and non-interference norms. The bloc is unlikely to issue a collective statement criticising any major power, but Singapore may work bilaterally to ensure ASEAN partners coordinate on energy security and supply chain contingency planning. Singapore has previously demonstrated a capacity for principled international positions — including its condemnation of Russia’s invasion of Ukraine — and may be expected to call for an immediate ceasefire and respect for international maritime law without explicitly aligning with either belligerent.
7. Sectoral Vulnerability Summary
| Sector | Risk Level | Key Transmission Channel | Immediate Government Response Expected |
| Energy / Utilities | Critical | Oil and LNG price shock; feedstock costs | Activate strategic petroleum reserve monitoring; EMA tariff review |
| Aviation / Logistics | High | Route cancellations; airspace closure; freight cost increases | CAA coordination with airlines; SIA support measures |
| Refining / Petrochemicals | High | Crude oil supply disruption; feedstock price volatility | EDB coordination with Jurong Island operators |
| Financial Services | Moderate-High | Risk-off capital flows; trade finance disruption | MAS exchange rate management; bank liquidity monitoring |
| Tourism / MICE | Moderate | Reduced Gulf inbound travel; corporate cancellations | STB contingency planning; marketing pivot to other markets |
| Manufacturing / Electronics | Moderate | Demand slowdown in key export markets (Japan, Korea) | EDB and MTI export market diversification guidance |
| Consumer / Retail | Low-Moderate | Petrol price pass-through; imported inflation | Consumer price monitoring; possible fuel duty review |
8. Policy Implications and Recommendations
8.1 Short-Term Measures (0–4 Weeks)
- Activate the National Energy Coordination Committee to conduct daily situational assessments of oil and LNG supply disruption risk.
- Coordinate with SIA, Scoot, and the Civil Aviation Authority on airspace re-routing contingency plans and passenger protection protocols.
- Issue a formal MAS communication reassuring markets of exchange rate policy continuity and monitoring of banking sector exposures.
- Engage diplomatic channels bilaterally with GCC states, the US, and ASEAN partners to signal Singapore’s call for cessation of hostilities and freedom of navigation.
- Review consumer electricity and petrol price pass-through mechanisms to mitigate immediate inflationary impact on lower-income households.
8.2 Medium-Term Measures (1–3 Months)
- Accelerate diversification of LNG supply agreements away from Qatari-concentrated contracts toward Australian, US, and East African suppliers.
- Evaluate the feasibility of expanding Singapore’s strategic petroleum reserve capacity, potentially in coordination with IEA member states.
- Launch EDB-led outreach to reassure foreign investors of Singapore’s continued stability and openness as a regional headquarters location.
- Commission MAS and MTI joint scenario modelling on extended conflict duration impacts on GDP growth, current account balance, and employment.
9. Conclusion
The US-Iran conflict that erupted on 28 February 2026 represents one of the most significant geopolitical shocks to Singapore’s strategic environment in decades. While Singapore has no direct military involvement and its bilateral trade with Iran is limited, its position as an open, trade-dependent, energy-importing hub in a globally integrated financial and logistics network renders it acutely vulnerable to second and third-order effects.
The critical variable determining the severity of Singapore’s exposure is the duration of the conflict and, above all, whether the Strait of Hormuz is effectively disrupted or closed. A conflict contained to two weeks or less with limited maritime interdiction would likely produce manageable macroeconomic headwinds. A prolonged conflict involving Hormuz closure or broader regional conflagration involving Gulf Cooperation Council states would pose a material threat to Singapore’s economic stability and could trigger a policy response of the scale not seen since the 2008 Global Financial Crisis or the COVID-19 pandemic.
Singapore’s institutional resilience — including its foreign exchange reserves, sovereign wealth fund resources, diversified trade partnerships, and experienced technocratic policy apparatus — provides meaningful buffers. However, the speed and unpredictability of the conflict’s escalation thus far underscore the urgency of preemptive contingency planning.
