Escalating conflict in the Strait of Hormuz, following US and Israeli actions against Iran, has resulted in an effective closure of this critical maritime bottleneck, leading to severe disruptions in global supply chains and especially of crude oil, gas and fertilisers. As of March 2026, Singapore businesses are facing a significant surge in energy and operating costs driven by skyrocketing crude oil and natural gas prices, resulting from intensified conflict in the Middle East. This energy shock is directly impacting fuel, electricity, and logistics costs, fuelling inflationary pressures on the Singapore economy and causing economists to raise inflation forecasts for 2026 (Straits Times, 10 March 2026).
This situation, combined with simultaneous challenges in the Red Sea, has created the most severe logistics disruption since the 2023 pandemic, characterized by soaring insurance costs, widespread shipping delays, and significant rerouting. Maritime traffic has come to a halt, following the start of strikes on 28 February 2026, vessel traffic through the Strait of Hormuz dropped by as much as 94%, with over 150 tankers anchored outside the Gulf. The situation is characterized as a “dual blockade” of the Strait of Hormuz and the Red Sea, leaving little room for quick logistical solutions and forcing a long-term reshaping of trade flows. Major carriers have suspended services to the Gulf and are diverting vessels around the Cape of Good Hope, adding 10 to 14 days to transit times and straining global container availability. Alternative ports such as Jeddah (Saudi Arabia) and Salalah (Oman) are facing severe congestion. Furthermore, Saudi Arabia is pivoting exports through its Red Sea port of Yanbu via pipeline (Carra Globe, 10 March 2026).
This scenario describes a “perfect storm” for global logistics, shifting the world’s economic centre of gravity away from traditional corridors. With the Strait of Hormuz and the Red Sea restricted, the primary impact is a massive capacity crunch; the extra 14 days around the Cape of Good Hope effectively removes about 10-15% of global shipping capacity because ships are tied up longer on a single voyage (APL Logistics 5 Marc 2026).
In terms of spillover over effects, this has caused surging Insurance Premiums as War risk insurance premiums for the region have surged, in some cases by more than 1000%, driving up the cost of moving energy and goods (Reuters, 6 March 2026). For instance, a tanker valued at US$200 million–$300 million may face a hull war risk premium of about US$7.5 million, rising from around 0.25% (US$625,000) prior to the conflict (Port News, 8 March 2026).
Impact on Logistics and Transhipment
As of early 2026, Singapore’s role as a primary global transshipment hub is under strain due to escalated geopolitical tensions in the Middle East—specifically the closure of the Strait of Hormuz—which have forced shipping lines to restructure routes and offload cargo early to avoid volatile regions. This has resulted in a surge of “vessel bunching” at local terminals, leading to increased waiting times for berths and tighter capacity, with experts warning of continued bottlenecks through the year (Business Times, 3 March 2026).
As a transshipment hub, Singapore is seeing increased activity as vessels opt to offload cargo early or face shortages, with experts warning of potential congestion at local ports. For first quarter 2026, there were Increased Transshipment Volume because vessels are discharging Singapore-bound cargo and even some Europe-bound cargo early to avoid risk, turning Singapore, along with Tanjung Pelepas and Port Klang, into critical congestion hotspots. The surge in activity has resulted in longer waiting times, with some container vessels facing wait times of two to three days in early 2026, compared to normal operations with some port-specific bottlenecks lasting even longer.
While PSA Singapore has activated more berths at its new Tuas Port, the “bunching” of off-schedule arrivals is testing capacity, leading to container yard congestion (Business Times, 3 March 2026). Logistics firms and freight forwarders in Singapore are experiencing significant cost increases, potentially rising by 30% to over 50% for cargo bound for the Middle East. Carriers are passing on higher operational costs—stemming from long detours around the Cape of Good Hope and higher insurance premiums through fuel surcharges and “risk” fees (Channel News Asia, 9 March 2026). Local small and medium enterprises (SMEs) are facing significant operational pressure, with 43% of SMEs citing high logistics costs as a top concern for 2026 (Lalamove website).
Retailers are bracing for potential shortages of goods, particularly those relying on Middle Eastern supply chains, during high-demand periods (such as Ramadan). Logistics players are suggesting increased local warehousing to buffer against inventory shortages caused by delayed shipments (Oliver Wyman website). In response to the high costs, some importers are consolidating cargo and exploring diversified sourcing strategies, though high inertia in established supply chains keeps reliance on local ports high (CPSCP website). Despite these disruptions, Singapore’s Tuas Port is expanding, with four more berths expected to become active in 2026 to handle the increased demand and improve future resilience.
Energy and Food Prices
Singapore is also exposed to the spike in energy and fertilizer prices (around one-third of global fertilizer trade passes through the Strait of Hormuz), increasing risks of food inflation and higher logistical costs for logistics-dependent firms (Straits Times, 13 March 2026). Singapore firms with Middle East operations are experiencing broken trade routes, forcing a shift to “new normal” operational strategies, such as pooling resources to manage higher, volatile shipping costs.
With crude oil prices potentially rising, businesses are facing increased fuel, electricity, and transportation costs, which fuels inflationary pressures. Singapore sources 55% of its crude oil from the Middle East. Brent crude prices have spiked past US$100 per barrel and every US$10 rise in oil prices is estimated to add 30–40 basis points to Singapore’s core inflation (Singapore Business Review, 16 March 2026). Nonetheless, Singapore maintains stockpiles, Singapore’s Minister-in-charge of Energy and Science, Dr. Tan See Leng, announced that the nation maintains fuel stockpiles, including LNG and diesel, sufficient to last for “months” (Channel News Asia12 March 2026). These reserves, which can be used by power generators, serve as a buffer against disruptions in the Middle East.
Increased Inflationary Pressures
The conflict risks a stagflationary environment by pushing up inflation, which may tighten monetary policy (Straits Times, 9 March 2026). Sector-Specific Vulnerability: Airlines, heavy industry, and shipping are most vulnerable, while energy importers face higher expenses. Major regional hubs like Dubai, Doha, and Abu Dhabi have faced closures or restrictions, leading to over 1,000 cancelled flights.
Conflict in the Strait of Hormuz is causing shipping delays, higher insurance premiums, and rerouting of vessels, directly impacting logistics-dependent firms. This disrupts “urgent” supply chains for high-value items like electronics and precision parts. The volatile situation creates a challenging climate for planning and investment, affecting overall business confidence.
Transportation and Logistics have been directly hit by pump price increases and emergency conflict surcharges. The Petrochemicals sector is facing higher feedstock costs and potential plant shutdowns on Jurong Island due to feedstock shortages (Channel News Asia, 9 March 2026). SMEs are affected by thinning margins as volatility in utilities and input costs is harder for smaller firms to absorb. In the Defence sector, companies like ST Engineering may see increased demand. For the Oil & Gas Services, firms such as Seatrium may benefit from higher energy prices and demand for offshore services (Straits Times, 3 March 2026).
Business strategic shifts are leading to overall delayed expansion, with companies being advised to hold off on expansion plans into the Middle East due to the high – risk premium. Major Singaporean firms like ST Engineering have activated business continuity plans and repatriated some staff from the region. To hedge against unpredictable delays, businesses are moving toward holding higher inventory levels and more working capital (Straits Times, 3 March 2026).
Economic Outlook
The Singapore government is monitoring the situation, with Senior Minister Lee Hsien Loong emphasizing the need for businesses to remain adaptable and for firms to potentially explore alternative, more secure supply sources. While the immediate impact on operations in the Middle East has been managed by restricting travel, the broader economic consequences of the conflict are expected to persist, requiring businesses to be cautious
The Ministry of Trade and Industry (MTI) is monitoring the situation as it threatens the 2026 GDP growth forecast of 2% to 4%. Analysts suggest the Monetary Authority of Singapore (MAS) may need to tighten policy in April 2026 to combat the resulting inflationary spike.
Singapore may see mixed economic impacts from the Middle East conflict affecting Dubai, with some capital flight to Singapore’s wealth management sector, but experiencing negative pressure from higher energy costs and supply chain disruptions. While investors are considering relocating assets from Dubai to Singapore, Singapore faces risks from increased inflation, higher shipping costs, and potential slowdowns in trade-dependent sectors.
While Singapore is seeing some specific “safe haven” gains, the overall economic impact of the Iran-Israel-US conflict is expected to be a net negative for Singapore’s economy due to global trade disruptions and rising costs.
