Executive Summary

On February 28, 2026, the United States and Israel launched a coordinated military campaign against Iran, initiating what has become the most significant Middle Eastern conflict in decades. Within its first week, the war has expanded to encompass Lebanon, Gulf states, Turkey, Cyprus, Azerbaijan, and Sri Lanka, and has triggered a near-blockade of the Strait of Hormuz — one of the world’s most critical energy chokepoints. This case study analyses the conflict’s trajectory, strategic outlook, and proposed solutions, with particular attention to its multidimensional impact on Singapore.

Singapore’s unique position as a small, open, trade-dependent economy with substantial energy, financial, and diaspora exposures renders it acutely vulnerable to the systemic shocks emanating from this conflict. The findings presented herein draw on publicly available reporting as of March 7, 2026.

1. Case Study: Background and Conflict Dynamics

1.1 Origins of the Conflict

The US–Israeli campaign, launched on February 28, 2026, followed a prolonged period of diplomatic failure and strategic escalation between Washington, Tel Aviv, and Tehran. While President Donald Trump has provided varying official justifications for the campaign, the stated objectives have coalesced around the elimination of Iran’s nuclear capabilities, the degradation of the Iranian Revolutionary Guard Corps (IRGC), and the forced removal of Supreme Leader Ayatollah Ali Khamenei — who was reportedly killed in the campaign’s opening days — thereby effectuating a fundamental restructuring of the Iranian political order.

Trump’s public demand for ‘unconditional surrender’ and his offer to assist in rebuilding Iran’s economy contingent upon the installation of a US-acceptable successor to Khamenei signal an ambition extending well beyond conventional military deterrence into coercive regime transformation.

1.2 Geographic Escalation

What began as a bilateral US–Israeli air campaign against Iranian targets has expanded rapidly into a regional conflagration. The following table maps the conflict’s geographic footprint as of March 7, 2026:

Theatre	Nature of Engagement	Key Development
Iran (Tehran)	Primary target of US–Israeli strikes	Mehrabad International Airport struck; 926 reported deaths
Lebanon	Israeli air campaign intensified	217 killed; 300,000 displaced; Beirut suburbs and Baalbeck struck
Gulf States (Dubai, Bahrain, Riyadh area, Qatar, Kuwait)	Iranian missile/drone retaliation	Ballistic missile intercepted near Riyadh; 10 drones targeted Qatar; civilian casualties in Kuwait
Iraq	Drone strikes on airports and oil facilities	Kurdish opposition groups also targeted
Sri Lanka	US torpedo strike	Iranian warship sunk in Indian Ocean
Cyprus, Turkey, Azerbaijan	Widening conflict zone	Nature of engagement still emerging
UN Peacekeeping (Lebanon)	Base struck by Israeli air strikes	3 Ghanaian peacekeepers wounded; international condemnation

1.3 Strategic Postures of Key Actors

United States

The US under President Trump has adopted a maximalist war objective: unconditional Iranian surrender and enforced regime change. The administration has rejected ceasefire proposals and diplomatic re-engagement, directed major defence firms to quadruple advanced weapons production, and struck over 3,000 Iranian targets within the conflict’s first week. Secretary of Defence Pete Hegseth has downplayed concerns about Russian intelligence support to Iran, suggesting US confidence in operational security.

Israel

Israel’s campaign operates across multiple fronts simultaneously — striking Tehran directly, intensifying operations in Lebanon against Hezbollah strongholds, and conducting strikes as far afield as Sri Lanka. The announcement of each new ‘broad-scale wave’ signals a deliberate escalatory doctrine designed to preclude Iranian strategic recovery.

Iran

Iran has pursued asymmetric retaliation, launching missile and drone attacks on Israel and Gulf states, and leveraging its proxies — Hezbollah in Lebanon and affiliated groups in Iraq. Most consequentially, Tehran has effectively blockaded the Strait of Hormuz, weaponising the world’s most critical oil transit route as a strategic coercive instrument.

Russia and China

Russia has called for an immediate ceasefire and is reportedly providing Iran with intelligence on US troop positions — a claim US officials neither confirm nor deny. China has remained conspicuously absent from active engagement, maintaining strategic ambiguity. Neither power has intervened militarily, preserving a fragile great-power equilibrium around the conflict.

Regional Actors

Saudi Arabia has intercepted Iranian ballistic missiles targeting US military installations on its soil, signalling de facto alignment with the US–Israel coalition. Qatar, Kuwait, Bahrain, and the UAE face direct exposure to Iranian retaliation while hosting significant US military infrastructure.

2. Strategic Outlook

2.1 Short-Term Trajectory (0–4 Weeks)

The US government has publicly stated the conflict may last four weeks or more. In the near term, several dynamics are likely to persist and intensify:

Continued aerial bombardment of Iranian military, governmental, and infrastructure targets by US and Israeli forces
Escalating Iranian retaliatory strikes across the Gulf, with risk of kinetic miscalculation involving Saudi Arabia or UAE — both pivotal energy exporters
Prolonged Strait of Hormuz disruption, with Iran demonstrating willingness and capacity to sustain the blockade
Deepening humanitarian crisis in Lebanon, where 300,000 have already been displaced and infrastructure is under sustained attack
Significant risk of UNSC paralysis, with Russia and China vetoing Western-backed resolutions while calling for ceasefires

2.2 Medium-Term Scenarios (1–6 Months)

Three plausible medium-term scenarios emerge from the current trajectory:

Scenario	Conditions	Probability	Key Risk
Enforced Iranian Capitulation	Sustained US-Israeli campaign achieves military objectives; successor regime installed	Low–Moderate	Prolonged insurgency; regional instability post-regime change
Negotiated Ceasefire	Mediation by Qatar/Oman/China; Iran accepts partial concessions	Moderate	US–Iran distrust; domestic opposition in Iran to any surrender terms
Protracted Regional War	Escalation draws in Saudi Arabia, Hezbollah fully mobilised; possible US–Russia friction	Moderate–High	Global energy shock; humanitarian catastrophe; nuclear risk escalation

2.3 Long-Term Structural Implications

Regardless of the conflict’s immediate resolution, its long-term structural consequences are already taking shape:

Accelerated global energy transition investment as economies confront Hormuz vulnerability
Reconfiguration of Middle Eastern security architecture, potentially displacing the US as sole regional guarantor
Deepening Iran–Russia–China alignment as an alternative security axis
Erosion of UN Security Council authority as a conflict-resolution mechanism
Normalisation of state-sponsored drone and missile warfare as instruments of coercive deterrence

3. Policy Solutions and Recommended Responses

3.1 International Diplomatic Framework

An effective resolution framework must address both the immediate cessation of hostilities and the underlying geopolitical drivers of the conflict. The following measures warrant urgent multilateral consideration:

Activation of a UN Secretary-General-mediated humanitarian corridor mechanism for Lebanon and Iran, modelled on precedents from the Syria and Yemen conflicts
Establishment of a neutral contact group comprising Qatar, Oman, Switzerland, and the UN High Commissioner for Refugees (UNHCR) to facilitate back-channel negotiations
UN General Assembly emergency session invocation under the ‘Uniting for Peace’ Resolution 377, bypassing UNSC veto paralysis
International Maritime Organisation (IMO) emergency protocol activation to ensure civilian shipping safety through the Strait of Hormuz, including multilateral naval escort arrangements
Immediate humanitarian aid mobilisation for Lebanon, coordinated through WHO, UNHCR, and WFP, with secure humanitarian corridors established under international law

3.2 Energy Market Stabilisation Measures

The disruption of Hormuz transit demands coordinated international energy market intervention:

Coordinated Strategic Petroleum Reserve (SPR) release by IEA member states to cushion oil price shocks
Emergency OPEC+ production flexibility measures, particularly from Saudi Arabia and UAE, to offset supply disruption
Expedited activation of alternative routing for LNG and crude oil, including Cape of Good Hope diversions and pipeline alternatives
Central bank and financial stability board coordination to manage commodity price inflation transmission into broader economies

3.3 Regional De-escalation Architecture

A sustainable post-conflict architecture requires institutional investment beyond the immediate crisis:

Reconvening of multilateral nuclear talks — potentially under a P5+1 successor format — to address Iran’s nuclear programme through verified compliance mechanisms rather than military coercion
Gulf Cooperation Council (GCC) emergency security consultations to develop collective defence postures for Iranian missile threats
International reconstruction fund for Lebanon, with conditionality linked to Hezbollah disarmament as per UNSC Resolution 1701

4. Impact on Singapore

4.1 Energy Security and Fuel Costs

Singapore imports virtually all of its energy needs, and a substantial proportion of its oil and gas supply transits the Strait of Hormuz or originates from Gulf producers. The blockade’s immediate impact on global crude prices — with WTI surging over 12% in a single week to above US$90 per barrel, marking the largest weekly gain on record — has direct and material consequences for Singapore:

Elevated fuel import costs will transmit rapidly into electricity tariffs for households and businesses via Singapore’s regulated electricity pricing mechanism
Aviation fuel surcharges at Changi Airport will increase airline operating costs, with potential dampening effect on Singapore’s air hub status and tourism recovery
Marine fuel costs for the Port of Singapore — the world’s second-largest port by container volume — will rise, affecting bunkering revenues and shipping cost competitiveness
Petrochemical feedstock costs on Jurong Island will increase, compressing margins for Singapore’s significant refining and petrochemical sector

Singapore’s energy reserves policy (the government maintains strategic petroleum reserves) provides a partial buffer, but sustained disruption over weeks or months would exhaust this capacity and necessitate demand-side measures.

4.2 Trade and Port Operations

Singapore’s trade-to-GDP ratio exceeds 300%, making it among the most trade-exposed economies globally. The current conflict threatens several dimensions of its trade architecture:

Trade Dimension	Risk	Severity
Shipping route disruption	Vessels avoiding Gulf routes will add 7–14 days via Cape of Good Hope, increasing freight costs	High
Cargo insurance premiums	War risk premiums for Gulf-transiting vessels will spike, affecting all goods	High
Middle East trade volumes	Singapore’s re-export trade to Gulf states (a significant market) will contract	Moderate
Port throughput	Rerouted vessels may temporarily boost transshipment volumes, but war uncertainty dampens bookings	Mixed
Supply chain disruption	Electronics, chemicals, and consumer goods supply chains with Middle East components affected	Moderate

4.3 Financial Markets and Investment Flows

Singapore functions as one of Asia’s premier financial centres and a key hub for wealth management, foreign exchange trading, and commodity financing. The conflict’s financial contagion effects are already materialising:

The Singapore dollar will face depreciation pressure as risk-off sentiment drives flows towards USD and safe-haven assets; SGD/USD volatility will increase
Singapore’s equity market (STI) will experience downward pressure, particularly in sectors with Gulf exposure — aviation, shipping, and petrochemicals
Regional wealth managers based in Singapore may face portfolio rebalancing demands from Gulf sovereign wealth fund clients whose geopolitical risk calculus has shifted
Singapore’s commodity trading sector — the city-state is a major hub for oil and LNG trading — will face both opportunity (volatility-driven trading revenues) and risk (counterparty defaults, contract disputes from disrupted deliveries)
Higher global oil prices will contribute to imported inflation, potentially complicating the Monetary Authority of Singapore’s (MAS) exchange-rate-based monetary policy calibration

4.4 Diplomatic and Security Considerations

Singapore’s foreign policy doctrine, anchored in ASEAN centrality, multilateralism, and the primacy of international law, places it in a structurally difficult position:

As a close security partner of the United States — with significant bilateral defence cooperation — Singapore cannot be seen to publicly oppose US military operations; yet as a small state dependent on a rules-based international order, it has strong institutional incentives to uphold UN Charter principles against unilateral military action
Singapore’s substantial Muslim-majority Malay community (approximately 15% of the population) will follow the conflict closely, with potential for domestic social tension if civilian casualties in Muslim-majority countries mount
Singapore’s role as a non-permanent UNSC member (if applicable at this date) or as a consistent multilateral voice would position it well to advocate for humanitarian corridors and ceasefire negotiations
The conflict strains Singapore–Iran diplomatic and commercial relations; Singapore has historically maintained working relations with Tehran that facilitate trade and diplomatic communication

4.5 Humanitarian and Diaspora Implications

Singapore hosts a resident expatriate community including nationals from Lebanon, Iran, and Gulf states. The conflict creates immediate practical demands:

Ministry of Foreign Affairs (MFA) will need to activate consular emergency protocols for Singaporean nationals in affected countries, including Lebanon and Gulf states
Repatriation logistics for Singaporeans in conflict zones will be complex given disrupted commercial aviation routes
Singapore’s healthcare and social support infrastructure may face increased demand from affected diaspora communities

4.6 Supply Chain and Food Security

Beyond energy, the conflict poses secondary supply chain risks that bear on Singapore’s food and essential goods security:

Fertiliser supply chains — a significant proportion of which route through or originate from the Middle East — could be disrupted, with downstream effects on global food prices and Singapore’s food import costs
Construction materials, including steel and cement with Gulf origins, may face price increases and availability constraints relevant to Singapore’s ongoing infrastructure programme
Pharmaceutical and medical supply chains with Middle Eastern distribution nodes may experience disruption, warranting precautionary stockpile reviews by the Health Sciences Authority

5. Singapore’s Strategic Response: Recommendations

5.1 Short-Term Measures

Activate MAS macroprudential monitoring protocols for commodity price inflation and exchange rate volatility; prepare SGD nominal effective exchange rate (NEER) policy adjustments if inflationary pressure intensifies
Convene inter-agency Energy Security Task Force under the Energy Market Authority (EMA) to assess reserves adequacy and activate demand-side management guidelines
Issue MFA travel advisories for Lebanon, Iran, Gulf states, and adjacent conflict zones; activate consular emergency hotlines
Engage Singapore’s network of Gulf and Iranian diplomatic channels to signal continued support for ceasefire initiatives and humanitarian aid coordination

5.2 Medium-Term Measures

Accelerate Singapore’s energy diversification strategy, including LNG import source diversification away from Gulf-dependent supply chains; prioritise Australian, US, and Southeast Asian LNG suppliers
Work with PSA International to develop contingency routing protocols for port operations under prolonged Hormuz disruption scenarios
Engage ASEAN partners to develop a coordinated regional statement supporting de-escalation, humanitarian access, and adherence to international maritime law — leveraging ASEAN’s non-aligned credibility
Initiate strategic stockpile reviews for essential commodities including food, pharmaceuticals, and petrochemical feedstocks

5.3 Long-Term Strategic Priorities

Deepen Singapore’s investment in renewable energy infrastructure to structurally reduce dependency on fossil fuel imports and associated geopolitical risk
Strengthen Singapore’s role as a neutral mediation hub and humanitarian coordination centre — an institutional niche consistent with its foreign policy identity and economic interests in regional stability
Advocate within multilateral forums (UN, WTO, IMO, IEA) for strengthened legal frameworks governing the protection of critical maritime chokepoints from military disruption

6. Conclusion

The US–Israeli military campaign against Iran, entering its second week as of March 7, 2026, represents a watershed moment in Middle Eastern geopolitics with systemic global consequences. For Singapore, the conflict is not a distant geopolitical event but a proximate economic, strategic, and humanitarian challenge. The near-blockade of the Strait of Hormuz, the surge in oil prices, the disruption of regional trade routes, and the risk of financial contagion all impinge directly on Singapore’s fundamental interests.

Singapore’s response must navigate a narrow but navigable path: maintaining essential security partnerships, upholding its principled multilateralist foreign policy identity, protecting its economic resilience, and lending its voice — however constrained — to the restoration of the rules-based international order that underpins its existence as a sovereign small state.

The conflict’s ultimate resolution remains deeply uncertain. What is certain is that Singapore’s institutional agility, strategic reserves, and diplomatic credibility — carefully cultivated over decades — represent its most valuable assets in weathering this storm.
