1. CASE STUDY: The Escalation into Lebanon
1.1 Background and Context
The current Lebanon crisis does not exist in isolation. It is the latest chapter in a decades-long cycle of conflict involving Israel, Hezbollah, and their respective backers — culminating in a new phase triggered by the broader U.S.-Israeli military campaign against Iran that commenced on 28 February 2026 (Operation Epic Fury).
Hezbollah, the Iran-backed Lebanese Shia militant organisation, had already been substantially weakened following a major war with Israel in 2024, which resulted in an estimated USD 14 billion in damages and economic losses to Lebanon, according to World Bank estimates. The November 2024 ceasefire saw the Lebanese army move into southern Lebanon and seize Hezbollah weapons caches, marking the furthest rollback of Hezbollah’s territorial presence in decades.
However, despite military losses, Hezbollah retained strategic depth, political constituencies in the Shia-majority south, and continued operational capacity — albeit degraded. The organisation’s alliance with Iran created a structural incentive to re-enter hostilities once Iran itself came under direct attack.
1.2 Chronology of Events (Late February – March 3, 2026)
| Date | Event |
|---|---|
| 28 Feb 2026 | U.S. and Israel launch “Operation Epic Fury” — strikes on Iranian nuclear and military infrastructure. Iran’s Supreme Leader Ayatollah Khamenei reportedly killed. |
| 28 Feb – 1 Mar | Iran launches retaliatory missile and drone strikes across the Gulf region, targeting UAE (Jebel Ali port, Abu Dhabi), Bahrain, Saudi Arabia, and Kuwait. Strait of Hormuz becomes effectively closed to commercial shipping. |
| 2 Mar 2026 | Hezbollah enters the conflict, launching drones and missiles at northern Israel — its first attacks in over a year. Lebanese government convenes emergency session. |
| 2 Mar 2026 | Lebanese government takes the unprecedented step of outlawing Hezbollah’s military activities, declaring the group’s armed wing illegal. |
| 2–3 Mar 2026 | Israel conducts waves of airstrikes on Beirut’s southern suburbs, hitting Hezbollah’s al-Manar TV headquarters, command centres, and weapons storage. At least 52 killed and 150+ wounded in Lebanon. 29,000 displaced. |
| 3 Mar 2026 | Israeli ground forces move into southern Lebanon in a declared “defensive” posture. Lebanese army withdraws from at least 7 forward operating positions. Hezbollah announces three separate strikes on military facilities in northern Israel. |
1.3 Key Actors
Hezbollah: Weakened by the 2024 war but driven to act by Iran-alliance obligations and domestic political calculus. Its military strikes have been described as largely symbolic, intercepted with minimal Israeli damage, while Israeli retaliation has been disproportionately devastating.
Israel: Pursuing a dual-front operation — primary strikes on Iran alongside reopening the Lebanese theatre to neutralise Hezbollah’s remaining strategic assets. Israeli Defence Minister authorised the military to take additional positions in southern Lebanon.
Lebanese Government: Under Prime Minister Nawaf Salam, the cabinet has taken a historically unprecedented stance — banning Hezbollah’s military and intelligence activities, signalling a rupture between the state and the armed group. This risks deepening domestic political fractures, with pro-Hezbollah media warning of civil war.
Lebanon: A country already suffering a near-40% cumulative GDP decline since 2019, with a fragile banking system, weak state institutions, and now facing renewed mass displacement and destruction. Lebanon’s food and fuel reserves are estimated at only 2–3 months of supply.
Iran: The principal backer of Hezbollah, now engaged in direct conventional conflict with the U.S. and Israel. Iran’s governance structure is described by analysts as institutionalised and decentralised, making a swift capitulation unlikely.
1.4 Strategic Significance of the Lebanese Theatre
Lebanon’s renewed involvement matters beyond its borders for several reasons:
- Hezbollah’s Proxy Value: As Iran’s most capable proxy, Hezbollah’s engagement extends Iran’s retaliatory reach against Israel without directly deploying Iranian forces.
- Second Front for Israel: Compels Israel to manage a northern front simultaneously with its Iran operations, stretching military resources.
- Domestic Lebanese Fracture: The government’s decision to ban Hezbollah’s military arm is constitutionally and politically extraordinary, threatening internal stability in a country with a fragile sectarian balance.
- Regional Contagion Risk: Lebanon’s instability risks spilling into Syria, creating additional ungoverned spaces and emboldening other Iranian proxies (Houthis, Iraqi militias).
2. OUTLOOK: Scenarios and Projections
2.1 Short-Term Outlook (March–April 2026)
The trajectory of the conflict will hinge on three variables: (1) whether U.S.-Iranian diplomatic channels can be reopened; (2) the physical status of the Strait of Hormuz; and (3) Hezbollah’s willingness and capacity to sustain offensive operations.
Scenario A — Rapid De-escalation (Low Probability): A ceasefire between the U.S./Israel and Iran, brokered within weeks, reduces Hezbollah’s strategic rationale for continuing attacks. Israeli forces withdraw from southern Lebanon. Echoes the June 2025 “12-day war” playbook, where oil price spikes faded and lasting macro disruption was limited.
Scenario B — Protracted Conflict (Moderate-High Probability): Iran pursues sustained asymmetric retaliation — Hormuz harassment, Hezbollah missile campaigns, Houthi reactivation in the Red Sea. Hezbollah continues limited but symbolically significant strikes. Lebanon faces full-scale Israeli ground operations. Oil prices push toward USD 100/barrel. The Lebanese state faces a governance collapse if Hezbollah retaliates domestically against the government’s ban.
Scenario C — Catastrophic Escalation (Low but Non-Trivial Probability): Iran activates nuclear deterrence posturing (intelligence assessments indicate enrichment at up to 90%), drawing broader international response. Hezbollah and other proxies launch coordinated multi-front attacks. Lebanon slides into civil conflict triggered by the government’s ban on Hezbollah.
2.2 Medium-Term Outlook for Lebanon (2026–2027)
Lebanon’s economic recovery — already fragile, with a projected 4% growth rate contingent on structural reforms — is now severely at risk. Any large-scale resumption of hostilities could:
- Delay IMF-mandated structural reforms, deterring international donor support
- Reverse tourist and remittance inflows, two of Lebanon’s primary economic lifelines
- Drive further displacement and brain drain
- Trigger a governance crisis if the parliament is unable to hold planned May 2026 elections
The World Bank had projected potential recovery contingent on Hezbollah disarmament and political normalisation. Both now appear distant.
3. PROPOSED SOLUTIONS
3.1 Diplomatic and Political
Immediate ceasefire framework: The UN Security Council should convene an emergency session to broker a ceasefire between all parties, building on the November 2024 precedent. Qatar and Oman — which have previously served as intermediary channels between the U.S. and Iran — are the most viable diplomatic facilitators.
Hezbollah disarmament roadmap: The Lebanese government’s ban on Hezbollah’s military wing, while unprecedented and significant, must be backed by a credible international framework. A phased disarmament roadmap, tied to political incentives and financial support, is necessary to prevent the ban from becoming a trigger for civil conflict rather than a genuine security transition.
Inclusive national dialogue in Lebanon: A multi-sectarian domestic dialogue mechanism, facilitated by the Arab League or UN Special Coordinator, is needed to prevent the government’s actions against Hezbollah from fracturing Lebanon’s sectarian balance irreparably.
3.2 Humanitarian
Immediate humanitarian corridor: An internationally guaranteed humanitarian corridor through Beirut’s port and airport is essential to prevent Lebanon’s civilian population from being cut off from food, medicine, and cash.
Refugee management: Regional partners — particularly Jordan, Egypt, and Gulf states — should formalise burden-sharing arrangements for displaced Lebanese, potentially through the UNHCR.
Reconstruction financing: The international community, led by Gulf donors and the World Bank, should pre-position reconstruction commitments to prevent a repeat of post-2020 Beirut port explosion recovery failures.
3.3 Strategic
Strait of Hormuz stabilisation: The U.S. and allied navies should prioritise restoring freedom of navigation through the Strait of Hormuz as a matter of global economic urgency. This may involve direct negotiations with Iran over shipping lane guarantees, even absent a comprehensive ceasefire.
OPEC+ emergency response: OPEC+ member states with pipeline access outside the Strait (Saudi Arabia’s East-West pipeline, UAE’s Fujairah pipeline) should maximise alternative supply routes to moderate the oil price shock.
4. IMPACT ON SINGAPORE
Singapore, as a small, open economy deeply integrated into global trade and energy supply chains, faces multidimensional exposure to the current Middle East crisis. Deputy Prime Minister Gan Kim Yong acknowledged before Parliament on 2 March 2026 that the conflict poses “a major risk to the nation,” warning of “significantly higher prices and weighed-down economic growth” if hostilities remain protracted.
4.1 Energy and Inflation
The Strait of Hormuz handles approximately 20% of the world’s oil supply and nearly 20% of global LNG. Its effective closure — following the withdrawal of commercial operators, insurers, and major shipping companies — constitutes the most acute energy supply shock since the 1970s oil embargo.
Oil price surge: Brent crude surged to over USD 82/barrel as of early March 2026, representing a 30% rise since January 2026. Barclays analysts have warned of a pathway toward USD 100/barrel in a protracted disruption scenario.
LNG exposure: Singapore’s power generation is predominantly gas-fired. Disruption to Qatari LNG flows (which transited the Strait at approximately 81 million tonnes in 2025) will tighten Asian LNG markets significantly, raising domestic electricity generation costs.
Inflation pass-through: Rising energy costs will feed into Singapore’s headline CPI through electricity tariffs, fuel surcharges, and transport costs. The Monetary Authority of Singapore (MAS) has confirmed it is maintaining the Singapore dollar’s appreciating policy band — a tool designed specifically to dampen imported inflation — while monitoring the situation.
Petrol and retail prices: Pump prices for motorists and retail energy costs for businesses are expected to rise materially in the near term if oil prices remain elevated.
4.2 Trade and Shipping
Singapore is the world’s second-largest container transshipment port and a critical node in global maritime logistics. The current crisis exposes the city-state in several ways:
Port throughput impact: Major shipping lines — Maersk, MSC, Hapag-Lloyd, and CMA CGM — have suspended operations through the Strait of Hormuz and are rerouting vessels via the Cape of Good Hope, adding 10–14 days to voyage times. This increases bunker fuel costs and reduces effective global shipping capacity, potentially leading to cargo pile-ups and throughput delays at Singapore’s ports.
Insurance premiums: London and Singapore are the world’s leading marine insurance hubs. As war-risk premiums spike to six-year highs, Singapore’s insurance and financial services sectors face increased claims exposure and operational complexity.
Trade balance: Singapore imports the vast majority of its energy. Higher energy import costs will widen the trade deficit and pressure the current account unless offset by higher oil-related services revenues.
Aviation hub disruption: Gulf airspace closures have disrupted Europe-Asia aviation corridors, affecting Changi Airport’s transit hub function. Travellers stranded at Changi — including transiting passengers unable to connect through Dubai, Doha, and Abu Dhabi — have been reported, with airlines such as Qatar Airways and Emirates operating only limited repatriation services.
4.3 Singaporeans Abroad
Singapore’s Ministry of Foreign Affairs (MFA) issued an urgent travel advisory on 28 February 2026, advising all Singaporeans to defer travel to Israel, Iran, and the wider Middle East, confirming no Singaporean casualties at the time of issuance.
Consular operations have been activated across the region. Singapore’s Embassy in Riyadh explored overland bus evacuations for Singaporeans in Bahrain to Riyadh, with onward flights. Singaporeans in the UAE were advised to consider transiting through Muscat, Oman, given UAE airspace restrictions. Emirates and Etihad are expected to resume limited Singapore-bound flights from 4–6 March 2026 respectively.
Changi Airport has been affected by stranded transit passengers — particularly those routed through Gulf hubs — highlighting the airport’s structural dependence on the Middle East as an aviation corridor.
4.4 Financial Markets
Singapore Exchange (SGX) and broader financial markets have experienced volatility consistent with global risk-off sentiment. The MAS confirmed on 2 March that currency and money markets are functioning normally, with the S$NEER remaining within its established policy band. However, sustained oil price increases and global equity market weakness — with S&P 500 futures falling in response to the conflict — will weigh on investor sentiment.
Safe-haven flows: As investors shift into Treasuries, gold, and the Swiss franc, Singapore dollar assets may experience some outflows, offset partially by Singapore’s own safe-haven status in the region.
Financial services sector: Singapore’s significant Middle East financial linkages — including sovereign wealth fund investments, trade finance for Gulf commodity flows, and Islamic finance operations — may face operational disruption in the near term.
4.5 Summary Table: Singapore’s Exposure
| Domain | Nature of Impact | Severity |
|---|---|---|
| Energy costs | Oil and LNG price surge; higher electricity and fuel prices | High |
| Inflation | Imported inflation through energy and shipping costs | High |
| Port throughput | Rerouting of vessels; shipping delays | Moderate–High |
| Aviation hub | Gulf airspace closures; transit disruptions at Changi | Moderate |
| Financial markets | Equity volatility; rising insurance premiums | Moderate |
| Singaporeans abroad | Evacuation logistics; consular activation | Moderate |
| LNG supply | Qatar LNG disruption; tighter Asian gas markets | High |
5. CONCLUSION
The re-entry of Lebanon into the broader Middle East conflict represents a dangerous escalation with consequences that extend well beyond the Levant. For a small, open economy such as Singapore, the conflict’s most immediate channels of impact are energy prices, shipping disruption, and aviation hub functionality — all of which are intrinsically tied to the Strait of Hormuz and Gulf stability.
The Lebanese state’s decision to ban Hezbollah’s military activities is historically significant but structurally precarious. Without a credible international diplomatic framework to support both a ceasefire and a phased transition away from Hezbollah’s armed presence, the ban risks precipitating the very civil conflict it seeks to prevent.
Singapore’s response — through the MAS’s currency policy, the MFA’s consular activation, and DPM Gan’s parliamentary disclosure — reflects the pragmatic, institutionalised approach to external shocks that characterises the city-state’s governance model. The central challenge ahead will be sustaining growth and price stability in an environment where the primary drivers of disruption are geopolitical rather than macroeconomic in origin, and therefore substantially beyond Singapore’s direct influence.
