Executive Summary

Operation Epic Fury — the joint U.S.-Israeli military campaign against Iran launched in early 2026 — has placed Kharg Island, Iran’s principal oil export terminal, at the centre of one of the most consequential geopolitical crises of the twenty-first century. This case study examines: (1) the strategic logic underpinning the potential seizure of Kharg Island; (2) the near- and medium-term outlook for the conflict; (3) proposed policy solutions and adaptive frameworks; and (4) the multidimensional impact on Singapore — a small, open, trade-dependent city-state uniquely exposed to disruptions in the Persian Gulf energy corridor.

1. Case Study: Kharg Island as a Strategic Fulcrum

1.1 Background and Historical Context

Kharg Island is a barren limestone outcrop located approximately 25 kilometres off Iran’s Persian Gulf coastline and some 480 kilometres northwest of the Strait of Hormuz. Constructed by the American Aramco consortium during the Pahlavi era in the late 1950s to accommodate supertankers too large for Iran’s shallow coastal waters, the island evolved into the logistical backbone of Iran’s hydrocarbon economy. Today, approximately 94 per cent of Iran’s crude oil exports — equivalent to roughly 1.5 to 1.7 million barrels per day — are loaded onto tankers at Kharg’s deep-water jetties.

The island has historically attracted the attention of adversaries seeking to undermine the Iranian state. During the Iran-Iraq War (1980–1988), Iraqi air and naval strikes partially disabled Kharg’s loading facilities on multiple occasions; however, Iran consistently repaired and restored operations. The terminal’s recurring vulnerability reflects both its immense strategic value and its inherent geographic exposure.

Kharg also featured in the 1979–1981 hostage crisis, when advisers to President Jimmy Carter proposed its seizure as economic leverage. The plan was ultimately shelved as too provocative. Remarkably, then-property developer Donald Trump publicly advocated seizing the island in a 1988 interview with The Guardian, suggesting a persistent strand of American strategic thinking about the island’s coercive potential.

1.2 The Strategic Logic of Seizure vs. Destruction

Operation Epic Fury, initiated in early 2026, has thus far targeted Iranian military infrastructure, naval assets, fuel depots, and — following the reported death of Supreme Leader Ali Khamenei — command-and-control centres. The Iranian Revolutionary Guard Corps (IRGC) has responded by closing the Strait of Hormuz, through which approximately one-fifth of global oil and LNG exports transit, precipitating an immediate spike in energy prices worldwide.

The core strategic question — whether to destroy or seize Kharg — carries fundamentally different implications:

Dimension

Seizure (Preferred U.S. Approach)

Dimension	Seizure (U.S. Preference)	Destruction (Advocated by Some Israeli Officials)
Immediate effect	Disrupts exports; retains infrastructure intact	Permanently destroys export capacity for years
Leverage over Iran	High — control over future revenue	Low — eliminates the asset entirely
Global energy impact	Moderate — manageable if Hormuz reopens	Severe — global oil shock, $150+ per barrel risk
Leverage over China	High — U.S. controls China’s primary crude source	Eliminated
Post-conflict utility	New Iranian govt must negotiate for oil revenue	Costly reconstruction required
Risk of sabotage	Iran could destroy terminal (cf. Kuwait 1990)	Moot

The U.S. preference for seizure reflects a calibrated cost-benefit calculation: maximum leverage over Iran and China at minimum long-term disruption to global energy markets. The White House’s National Energy Dominance Council, established in 2025, signals that energy geopolitics is central to the Trump administration’s strategic worldview.

1.3 Military Feasibility

Military analysts assess that Kharg Island’s defences are relatively limited: ageing surface-to-air missile batteries and coastal anti-ship missile systems. The Iranian Navy has reportedly lost in excess of 30 vessels since the commencement of Operation Epic Fury. Given the island’s geographic isolation — separated from the Iranian mainland by 15 kilometres of open water — the capacity of land-based Iranian forces to contest an amphibious or airborne seizure is constrained. U.S. naval destroyers and carrier-based air defence could plausibly establish a defensive perimeter well offshore.

Looking ahead, seizure would give the U.S. leverage during negotiations, no matter which regime is in power after the military operation ends. — Petras Katinas, Royal United Services Institute, Europe

2. Outlook: Scenarios and Trajectories

2.1 Near-Term Outlook (0–6 Months)

Three principal scenarios are foreseeable in the near term:

Scenario A: Seizure of Kharg Island (Most Likely)

• U.S. naval and special operations forces seize Kharg in a combined arms operation, supported by Israeli air cover.
• Iran retaliates with ballistic missiles and proxy attacks across the region but is constrained by degraded military capacity.
• The Strait of Hormuz remains partially or fully closed for 3–6 months, sustaining energy price volatility.
• Oil prices stabilise at $100–120 per barrel once seizure signals a ceiling on Iranian retaliation.

Scenario B: Negotiated De-escalation

• Iran, facing internal fiscal collapse without oil revenues, seeks back-channel negotiations mediated by Oman or Qatar.
• Kharg Island becomes a bargaining chip: the U.S. offers to return operational control in exchange for nuclear concessions and IRGC dissolution.
• Energy markets partially recover; Hormuz reopens within 2–3 months.

Scenario C: Prolonged Conflict and Regional Escalation

• Iranian proxies (Hezbollah, Houthi remnants, Iraqi militias) mount sustained attacks on Gulf state infrastructure and Red Sea shipping.
• Iran activates its nuclear programme as a deterrent, triggering further U.S.-Israeli escalation.
• Oil prices breach $150 per barrel; global recession risk rises materially.

2.2 Medium-Term Outlook (6–24 Months)

Irrespective of the near-term scenario, several structural dynamics are likely to persist:

• Iran’s fiscal position deteriorates sharply, with oil revenues — constituting approximately 40 per cent of the government budget — curtailed.
• A post-conflict Iranian government, whether reformist or transitional, will face intense U.S. conditionality before regaining Kharg’s revenue streams.
• China, deprived of its primary discounted crude source, accelerates diplomatic engagement with Gulf Cooperation Council (GCC) states and potentially increases purchases from Russia and Venezuela.
• The global energy transition may paradoxically accelerate as elevated prices incentivise renewable deployment in import-dependent economies.
• The United States consolidates strategic influence over the Persian Gulf energy corridor, reshaping the post-Cold War order in the Middle East.

3. Solutions and Policy Frameworks

3.1 For the United States and Coalition Partners

A coherent endgame strategy for Operation Epic Fury requires addressing three interdependent challenges:

A. Managing Kharg Island Post-Seizure

• Establish a multilateral administrative authority — potentially under UN Security Council mandate — to manage Kharg’s operations, insulating the U.S. from accusations of resource imperialism.
• Maintain the island’s operational integrity to prevent Iranian sabotage (cf. Iraqi destruction of Kuwaiti oil infrastructure in 1990–91).
• Develop a transparent revenue escrow mechanism, ensuring oil income is ring-fenced for post-conflict Iranian reconstruction rather than withheld indefinitely.

B. Reopening the Strait of Hormuz

• Negotiate a phased Hormuz reopening as part of a broader ceasefire framework, potentially through GCC intermediaries.
• Deploy combined naval task forces under a U.S.-led coalition to guarantee freedom of navigation and deter Iranian mining operations.

3.2 For the International Community

• The United Nations Security Council should convene an emergency session to explore a framework agreement preserving Iran’s oil infrastructure while mandating IRGC disarmament.
• G20 economies should coordinate emergency releases from strategic petroleum reserves (SPRs) to dampen price spikes during the crisis period.
• International financial institutions (IMF, World Bank) should prepare a contingency framework for Iranian post-conflict reconstruction, conditional on political reform benchmarks.

3.3 For Singapore: Adaptive Policy Responses

Singapore’s policy response must operate across multiple dimensions simultaneously, as elaborated in Section 4. Core prescriptions include:

• Immediate activation of SPR coordination with the International Energy Agency (IEA).
• Diplomatic engagement through ASEAN to articulate the bloc’s collective interest in a swift, negotiated resolution.
• Accelerated diversification of energy import sources and intensification of renewable energy deployment.
• Proactive financial market stabilisation measures by the Monetary Authority of Singapore (MAS).

4. Impact on Singapore: A Multidimensional Analysis

Singapore’s exposure to the Iran crisis is disproportionate to its size. As a city-state with no indigenous energy resources, a port handling approximately 40 per cent of the world’s supertanker traffic, and an economy deeply integrated into global trade and finance, Singapore faces material risks across four principal domains.

4.1 Energy Security

Immediate Vulnerabilities

Singapore imports virtually all of its energy. Approximately 95 per cent of electricity is generated from natural gas, a substantial portion of which transits the Strait of Hormuz — currently closed by Iranian action — or is sourced from regional LNG suppliers exposed to Middle Eastern price benchmarks. The closure of Hormuz has already caused LNG spot prices to spike sharply, with immediate pass-through implications for electricity tariffs and industrial operating costs.

Key StatisticOne-fifth of all global oil and LNG exports — roughly 21 million barrels of oil equivalent per day — transit the Strait of Hormuz. Singapore’s refinery sector, one of Asia’s largest, processes significant volumes of Gulf crude.

Downstream Refining Sector

Singapore hosts one of the world’s largest refining and petrochemical complexes on Jurong Island, processing crude primarily from the Middle East. Disruption to Gulf crude supply chains constrains feedstock availability, reduces refinery utilisation rates, and compresses margins. If prolonged, this could trigger temporary shutdowns and consequent job losses in the energy sector.

Mitigation Levers

• Singapore maintains strategic petroleum reserves (SPRs), though their precise volume is classified. Activation in coordination with the IEA is a first-order response.
• Diversification towards Australian, African, and U.S. LNG suppliers — already underway prior to the crisis — should be accelerated through long-term offtake agreements.
• The government should consider expedited approvals for solar energy and regional power import projects under the ASEAN Power Grid framework.

4.2 Trade and Port Operations

The Port of Singapore is the world’s second-busiest by container volume and the largest bunkering port globally. It sits at the junction of the Malacca Strait and South China Sea routes — the primary alternative to Hormuz-routed shipping for vessels re-routing around the Persian Gulf crisis.

Paradoxical Short-Term Opportunity

Counterintuitively, the closure of Hormuz and the resulting diversion of shipping around the Cape of Good Hope — or through alternate Asian routing — may temporarily boost transit call volumes at Singapore, as vessels require additional bunkering and port services on longer voyages. Singapore could position itself as a critical logistics hub for re-routed energy cargoes.

Medium-Term Risks

• A sustained global recession induced by an energy price shock would suppress trade volumes, reducing port throughput and container handling revenues.
• Elevated bunker fuel prices increase shipping costs, dampening overall trade flows and export competitiveness for Singapore’s manufacturing sector.
• Disruption to Gulf-linked supply chains — particularly for electronics and chemicals — could affect Singapore-based multinational operations.

4.3 Financial Markets and the Singapore Dollar

Singapore’s financial sector — the third-largest in Asia — is deeply integrated into global capital markets. The current crisis has generated several channels of financial contagion:

Channel	Implications for Singapore
Oil price inflation	Elevates cost-push inflation, pressures MAS to tighten monetary policy via S$NEER appreciation, potentially dampening export competitiveness.
Risk-off capital flows	Safe-haven demand may strengthen the SGD against regional peers, benefiting importers but hurting exporters.
GCC sovereign wealth fund exposure	Singapore is a major destination for GCC sovereign wealth (GIC, Temasek counterparty relationships); market volatility may trigger redemptions.
Iranian sanctions compliance	Singapore financial institutions must ensure strict adherence to expanded U.S. sanctions architecture targeting Iranian oil transactions.
Regional banking stress	Elevated credit risk in Middle East-exposed loan books of Singapore-based banks operating regionally.

4.4 Diplomatic and Geopolitical Positioning

Singapore’s foreign policy is founded on multilateralism, respect for international law, and strategic non-alignment. The Iran crisis presents acute diplomatic tensions:

The ASEAN Dimension

Singapore holds significant influence within ASEAN as a financial and diplomatic hub. The bloc’s collective dependence on Middle Eastern energy creates a shared interest in crisis resolution. Singapore should leverage ASEAN chairmanship rotations and the ASEAN-GCC dialogue mechanism to channel regional de-escalation pressure.

The U.S.–China Nexus

Singapore’s perpetual diplomatic tightrope — maintaining robust alliances with the United States while sustaining deep economic ties with China — is tested acutely by the Iran crisis. U.S. control of Kharg directly constrains China’s access to discounted Iranian crude, heightening Sino-American tensions. Singapore must carefully avoid being perceived as endorsing either camp’s strategic posture.

The Monetary Authority of Singapore and the Ministry of Trade and Industry have historically managed such tensions through calibrated statements emphasising rules-based international order and freedom of navigation — principles upon which Singapore’s own commercial interests depend.

Humanitarian Diplomacy

Singapore can carve a distinctive diplomatic niche by advocating for humanitarian corridors, safe passage for civilian shipping, and the protection of critical energy infrastructure under international humanitarian law. This positions Singapore as a principled interlocutor rather than a passive bystander.

5. Conclusion

The potential seizure of Kharg Island represents one of the most consequential acts of coercive economic statecraft contemplated in the post-Cold War era. By potentially acquiring control over 94 per cent of Iran’s oil export capacity without committing troops to the Iranian mainland, the Trump administration may achieve strategic objectives — Iranian regime containment, leverage over China, energy market dominance — at a fraction of the human and financial cost of conventional invasion.

For Singapore, the crisis is a stress test of the city-state’s foundational vulnerabilities: energy import dependence, trade exposure, financial market integration, and the perpetual challenge of navigating great-power competition. The appropriate response is neither passive nor alarmist, but proactive and calibrated: activating reserves, diversifying supply chains, reinforcing diplomatic channels, and positioning Singapore as an indispensable node in whatever post-crisis regional order emerges.

History suggests that small states with sophisticated institutions, clear strategic communication, and nimble economic governance are often best placed to capitalise on the dislocations created by great-power conflict. Singapore’s response to Operation Epic Fury will be a defining test of that proposition.
