Impact Assessment of the US-Israel Strike on Iran (March 2026)
Published: 1 March 2026 | Classification: Open Source Analysis | Region: Southeast Asia / Middle East
| EXECUTIVE SUMMARYOn 28 February 2026, the United States and Israel jointly executed ‘Operation Epic Fury’, a coordinated military strike on Iran that killed Supreme Leader Ayatollah Ali Khamenei. The event precipitated immediate airspace closures across the Gulf and broader Middle East, with cascading consequences for global trade flows, energy markets, and geopolitical alignments. For Singapore — a small, open, trade-dependent city-state with deep structural ties to the Middle East and global supply chains — the ramifications are profound and multi-dimensional. This case study examines the immediate, medium-term, and structural impacts across aviation, energy, trade, finance, and strategic posture. |
1. Contextual Background
The elimination of Khamenei, who had led the Islamic Republic since 1989 following the death of Ayatollah Khomeini, constitutes one of the most consequential acts of state-directed decapitation in modern geopolitical history. Unlike the targeted killing of military commanders such as Qasem Soleimani in 2020, this strike directly targeted the apex of the Iranian theocratic-political system, triggering an acute succession crisis alongside the expected retaliatory calculus.
Operation Epic Fury was reportedly authorised and monitored by the White House, with US President Donald Trump confirming Khamenei’s death via Truth Social. The strike’s timing — approximately six weeks before a scheduled US presidential visit to China — introduces a strategic signalling dimension aimed at asserting unilateral US power projection capacity before entering high-stakes great-power negotiations.
For Singapore, the event is not merely a distant geopolitical flashpoint. The Republic’s structural dependencies on Gulf energy, Middle East-routed aviation corridors, and open global financial systems mean that shocks originating in the Gulf translate directly into domestic economic and security pressures.
2. Immediate Impact: Aviation and Logistics
2.1 Airspace Closures and SIA / Scoot Operations
Flightradar24 data from 1 March 2026 confirmed virtually empty airspace over Iran, Iraq, Kuwait, Israel, Bahrain, the UAE, and Qatar. Dubai International Airport, Abu Dhabi International Airport, and Hamad International Airport in Doha — all critical transit nodes on Southeast Asia-to-Europe routing — were suspended or severely restricted. Singapore Airlines (SIA) and Scoot confirmed 26 flight cancellations affecting Middle East sectors, with rerouting adding significant operational costs where flights were maintained.
The Gulf accounts for a substantial share of SIA’s long-haul passenger and cargo throughput. Dubai alone is among SIA’s highest-revenue routes, serving both premium leisure and business travellers, as well as cargo connections into the Indian subcontinent and Africa. Prolonged closures — or elevated insurance premiums on Gulf overflight — compress airline margins and force rerouting via Central Asia or the Indian Ocean, adding 2-4 hours to multiple European routes.
| Airline | Routes Affected | Suspension Period | Singapore Relevance |
| Singapore Airlines / Scoot | Middle East sectors | Ongoing (as of 1 Mar) | Direct — flagship carrier of Singapore |
| Emirates | All Dubai operations | Until 3 PM UAE, 2 Mar | High — major codeshare partner of SIA |
| Qatar Airways | All QR flights | Until at least 9 AM, 2 Mar | High — Changi hub competitor/partner |
| Cathay Pacific | Dubai, Riyadh, Al Maktoum freighters | Ongoing | Moderate — competitor, cargo overlap |
| Air India | Delhi/Mumbai to Europe & North America | Select flights cancelled | Moderate — Indian diaspora routes from SIN |

2.2 Changi Airport’s Competitive Position
Paradoxically, Changi Airport may derive a short-term competitive benefit as a transit hub if Gulf hubs remain unavailable over an extended period. Passengers rerouting from Europe to Southeast Asia or Australasia may pivot to Changi-connected itineraries. However, this benefit is contingent on SIA and partner airlines maintaining operational capacity — itself compromised by overflight restrictions — and would be overwhelmed by the broader economic depression of travel demand if regional conflict escalates.
The cargo dimension is more immediately critical. Singapore’s position as a global logistics node means that any disruption to Middle East-transiting cargo — pharmaceuticals, semiconductors, luxury goods, perishables — will either reroute through Changi (providing uplift) or be delayed entirely (suppressing cargo revenue). The net effect depends heavily on escalation trajectory.
3. Energy Market Exposure
3.1 Strait of Hormuz Risk
The most acute macroeconomic risk for Singapore derives not from airspace closures per se, but from the potential disruption of energy flows through the Strait of Hormuz. Approximately 20-21 million barrels of crude oil transited the Strait daily in 2024, representing roughly one-fifth of global petroleum liquids consumption. Iran has historically threatened to close or mine the Strait in the event of military confrontation; the killing of the Supreme Leader materially elevates this risk.
Singapore’s economy is deeply exposed to oil price volatility through three channels: as the world’s third-largest oil trading hub, as a major refining centre (with refinery capacity of approximately 1.5 million barrels per day at Jurong Island), and as a bunkering port serving a global fleet. An oil price spike of 30-50% — plausible in a Hormuz closure scenario — would compress refining margins, increase bunkering costs, and create inventory valuation complexities for trading houses headquartered in Singapore.
| ANALYTICAL NOTE — HORMUZ SCENARIOIran’s Islamic Revolutionary Guard Corps (IRGC) retains both the motivation and the technical capability to threaten Hormuz shipping even absent central government coordination — a scenario made more likely by the decapitation of the supreme leadership and the ensuing succession uncertainty. IRGC factions could act autonomously or pre-emptively. Singapore’s refining and trading sector should model a 60-90 day elevated-risk window as baseline. |
3.2 Piped Gas and LNG Implications
Singapore is entirely dependent on imported energy, with piped natural gas from Indonesia and Malaysia complemented by LNG imports. While Singapore’s gas supply does not transit the Gulf directly, global LNG spot prices — to which Singapore’s longer-term contracts are partly indexed — will spike if Middle East gas flows are disrupted and buyers globally scramble for alternative supply. This translates into elevated electricity generation costs and, consequently, inflationary pressure on industrial and residential consumers.
4. Trade and Supply Chain Disruption
Singapore’s role as a transhipment hub for goods moving between Asia, the Middle East, and Europe positions it at the intersection of trade corridors that are now severely disrupted. The port of Singapore — consistently ranked among the world’s busiest — handles substantial containerised cargo with Gulf and Red Sea origin or destination. While sea routes have not been officially restricted as of 1 March 2026, shipping companies will impose war-risk surcharges and may suspend services to Gulf ports, echoing the disruptions caused by Houthi attacks on Red Sea shipping in 2023-2024.
| Sector | Exposure Level | Primary Risk Vector | Estimated Impact |
| Oil refining & trading | Critical | Hormuz disruption, price volatility | Revenue swing +/- USD 2-4B annually |
| Port & shipping services | High | Gulf port closures, war-risk surcharges | Volume decline on Middle East routes |
| Aviation (SIA/Scoot) | High | Airspace closures, rerouting costs | 26 cancellations confirmed; ongoing |
| Electronics & semiconductor logistics | Moderate-High | Air cargo rerouting delays | Supply chain timing disruption |
| Financial services | Moderate | Oil price spike, risk repricing | Portfolio valuation, credit exposure |
| Tourism (inbound from Middle East) | Moderate | Flight cancellations, travel aversion | GCC high-spend tourism decline |
| Construction & real estate | Low-Moderate | UAE-based Singaporean firms | Project delays if Gulf operations halted |

5. Financial Market and Investment Implications
Singapore functions as a major regional financial centre and wealth management hub, with the Monetary Authority of Singapore (MAS) overseeing an asset management industry exceeding SGD 5.4 trillion. The financial system has four primary exposure vectors in the current crisis.
5.1 Sovereign Wealth and GCC Capital Flows
Gulf Cooperation Council sovereign wealth funds — including Abu Dhabi Investment Authority, Qatar Investment Authority, and Kuwait Investment Authority — are significant investors in Singapore assets, including real estate, listed equities, and private equity. Geopolitical destabilisation may trigger repatriation or reallocation of GCC capital, creating liquidity pressure in specific asset classes, notably Grade-A commercial property and SGX-listed entities with Gulf investor bases.
5.2 Oil Price Transmission
Singapore’s stock exchange (SGX) has meaningful exposure to energy-adjacent sectors through shipping trusts, commodity traders, and integrated energy companies. A sustained oil price spike is simultaneously positive for upstream operators and revenue accruing to Singapore’s refining and trading hub, while being negative for energy-intensive manufacturers and transportation operators. Net SGX impact is likely negative given the tourism, aviation, and logistics overhang.
5.3 Safe-Haven Currency Dynamics
The Singapore Dollar (SGD) has historically functioned as a regional safe-haven currency given MAS’s credibility and Singapore’s strong current account position. Capital inflows during periods of regional stress may appreciate the SGD, compressing export competitiveness for Singapore’s manufacturing and services sectors. MAS may need to adjust its exchange-rate centred monetary policy framework in response.
5.4 Insurance and Reinsurance
Singapore has developed a significant insurance and reinsurance market. War-risk and political-risk lines will see claims and reserve increases, while reinsurance capacity for Gulf-related risks will tighten globally, affecting premium pricing for all regional operators.
6. Strategic and Geopolitical Dimensions
6.1 Singapore’s Principled Non-Alignment Under Strain
Singapore’s foreign policy has long been characterised by a commitment to international law, multilateralism, and the principle that small states must uphold a rules-based international order to survive. Operation Epic Fury — a unilateral military action by a great power and its ally resulting in the assassination of a sitting head of state — poses a direct challenge to these normative foundations. Singapore will face pressure from both Western and Islamic-majority interlocutors to articulate a position.
Singapore’s approximately 15% Muslim-majority population adds a domestic dimension to the government’s foreign policy calculus. While the People’s Action Party government has extensive experience managing ethnic and religious sensitivities, a prolonged or escalating conflict with visible civilian casualties in Iran could generate domestic civil society pressures and require careful management by MUIS (the Islamic Religious Council of Singapore) and the government.
6.2 ASEAN’s Collective Impotence
The Association of Southeast Asian Nations (ASEAN), of which Singapore is a founding and influential member, is structurally ill-equipped to respond to the Middle East crisis. The ASEAN Charter’s principles of non-interference and consensus-based decision-making preclude any collective response, leaving member states to manage their bilateral exposures individually. Singapore, as ASEAN’s most globally integrated economy, will bear a disproportionate share of the economic spillover while having minimal political leverage to influence the conflict’s trajectory.
6.3 US-China Great Power Framing
The characterisation of Operation Epic Fury as strengthening Trump’s hand ahead of a China visit introduces a significant strategic variable. If the US-China summit produces new frameworks for technology export controls, currency arrangements, or Taiwan-related understandings, Singapore — which navigates the US-China rivalry with particular care given its ethnic-Chinese majority and deep US security ties — could face renewed pressure to align more explicitly with Washington. Singapore’s longstanding policy of maintaining substantive relations with both powers will be tested in a post-Khamenei world where the US has demonstrated willingness for high-risk unilateral action.
| STRATEGIC IMPLICATION FOR SINGAPOREThe most consequential long-term impact on Singapore may not be economic but normative: Operation Epic Fury demonstrates that the rules-based international order Singapore has championed as existential to its security can be suspended by great powers when strategically convenient. This challenges the foundational premise of Singapore’s foreign policy and may require a recalibration of its diplomatic and defence postures. |
7. Policy Responses and Recommendations
Based on the foregoing analysis, the following policy-relevant recommendations emerge for Singapore’s government, statutory boards, and private sector actors:
Short-Term (0–30 days)
- MAS should activate contingency liquidity monitoring for SGX-listed energy and aviation sectors and assess GCC capital flow volatility.
- Civil Aviation Authority of Singapore (CAAS) and SIA should activate established crisis protocols for extended airspace closures, including rerouting agreements and passenger compensation frameworks.
- The Singapore Tourism Board should prepare demand-side recovery messaging for Middle Eastern source markets, pre-positioned for deployment once airspace reopens.
- The Ministry of Foreign Affairs (MFA) should issue a measured statement reaffirming Singapore’s commitment to international law and humanitarian norms without explicitly condemning the strike — a calibrated diplomatic non-alignment.
Medium-Term (1–6 months)
- Energy market exposure should prompt a review of Singapore’s strategic petroleum reserve adequacy and refinery feedstock diversification to reduce Hormuz dependence.
- MAS and EDB should engage proactively with GCC sovereign wealth entities to provide confidence on Singapore’s investment environment stability.
- Singapore should use its non-permanent Security Council candidacy platform (if applicable) or UN General Assembly presence to advocate for de-escalation and civilian protection in any Iranian conflict theatre.
- Changi Airport Group should model medium-term passenger flow scenarios under 60, 90, and 180-day Gulf closure scenarios and prepare capacity adjustments accordingly.
Structural / Long-Term
- Singapore’s National Security Coordination Secretariat (NSCS) should commission a strategic review of dependencies on Middle East energy transit and Gulf aviation corridors, with a view to systemic resilience enhancement.
- The Republic’s defence posture, already premised on deterrence and strategic ambiguity, should be reviewed in light of the demonstrated willingness of great powers to conduct decapitation strikes on sovereign heads of state — a precedent with implications for small-state security doctrines globally.
- Singapore’s financial sector should develop specific stress-test scenarios for a 6-month Hormuz disruption, incorporating second-order effects on global trade finance and insurance markets.
8. Conclusion
Operation Epic Fury and the killing of Ayatollah Khamenei represent a structural rupture in Middle East geopolitics whose full implications will take months or years to fully manifest. For Singapore, the immediate disruptions — 26 flight cancellations, oil price uncertainty, Gulf hub closures — are economically significant but manageable within existing resilience frameworks. The more consequential risks lie in the medium-term: a sustained Hormuz disruption, a reconfiguration of GCC-Asia capital flows, and the normative erosion of the rules-based order Singapore depends upon.
Singapore’s response will require its characteristic combination of pragmatic adaptability and principled engagement: managing immediate economic exposure with professional competence, while using its diplomatic standing to advocate — however modestly — for de-escalation and the restoration of the international norms that underpin the small state’s security in an anarchic world.
