Bypassing Hormuz: How Asian FOB and CIF Flows Can Keep EN590 and Jet A1 Moving

Enerdealers Editorial

The Strait of Hormuz has once again become the world’s most dangerous chokepoint, and Asia is on the front line of the disruption. Roughly 84% of crude and 83% of LNG shipped through Hormuz in 2024 were destined for Asian markets, including China, India, Japan, and South Korea, making the region uniquely exposed to any interruption. The latest crisis—with partial closures, military exercises, and escalating threats—has already driven prices higher and forced governments and corporates into emergency procurement mode.

At the same time, structural demand for diesel and jet fuel across Asia is still robust: Singapore remains a leading refined‑product and aviation hub, and Southeast Asian jet fuel demand is expected to grow strongly through the next decade. This mix of geopolitical risk and underlying demand means traders, refiners, and end‑users are looking for practical ways to reduce Hormuz‑related exposure—without sacrificing volume, quality, or flexibility.

1. How the Hormuz Crisis Is Hitting Asia’s Energy Flows

The Strait of Hormuz is a narrow waterway—shipping lanes are only a few kilometers wide—that connects the Gulf’s major producers with global markets. A significant share of the world’s crude and condensate exports, as well as LNG flows from Qatar and other Gulf exporters, must pass through this chokepoint. When tensions flare, physical shipments can be delayed, rerouted at higher cost, or temporarily halted, while freight and insurance premiums spike across the board.

Asian economies are particularly vulnerable because their import baskets are heavily skewed toward Gulf crude and LNG. China, India, Japan, and South Korea alone account for about three‑quarters of the oil and the majority of LNG that transit Hormuz. As the latest crisis unfolded, governments in the region resorted to stockpile releases, price caps, and rationing measures to buffer domestic markets. South Korea even imposed a fuel price cap for the first time in three decades, while urgently seeking alternative routes and suppliers.

For refined products, the shock has been just as acute. China reacted by banning exports of diesel, gasoline, and aviation fuel until at least the end of March to safeguard domestic availability. That decision abruptly removed a key source of spot barrels for Southeast Asian buyers who had grown accustomed to Chinese exports filling shortfalls in diesel and jet. At the same time, reduced LNG inflows via Hormuz have forced several Asian countries to lean harder on coal and oil for power generation, tightening regional balances further.

Singapore’s Jurong Island has cemented its position as Asia’s primary refined‑products gateway, with high tank density, developed logistics, and an efficient regulatory environment.

2. Diesel and Jet Fuel: The Weak Links in Asia’s Supply Chain

2.1 EN590 diesel under stress

Diesel remains the backbone of Asia’s logistics, industrial, and agricultural sectors, even as policymakers push for electrification and cleaner fuels. EN590‑grade diesel, aligned with European ultra‑low sulfur specifications, has gained traction in international trade because it simplifies compliance for multinational buyers and allows for flexible deployment across fleets and geographies.

Yet regional supply is structurally tight. Singapore’s Jurong hub is a major refined‑product center, but it must import a large share of EN590, rather than producing all volumes locally. Those imports arrive with freight costs and local premiums layered on top, which can make EN590 in Jurong more expensive than equivalent barrels in Rotterdam even in normal times. In a crisis, when Hormuz is constrained and Chinese exports are curtailed, that premium can widen as traders bid against each other for limited prompt lots.

This tension is already visible in the market. Analysts note ongoing volatility in EN590 premiums between Rotterdam, Fujairah, Jurong, and Asia‑Pacific hubs, driven by refinery runs, freight, and geopolitics. With Gulf‑to‑Asia routes under pressure and traders wary of voyage risk through Hormuz, the ability to access ready‑stored EN590 in Asian hubs —especially on flexible FOB terms— becomes strategically important.

2.2 Jet A1 in a recovering aviation market

On the aviation side, demand for Jet A1 in Southeast Asia is expected to grow at a healthy pace through 2033 as tourism rebounds and regional airlines expand networks. Singapore functions as a key jet fuel export hub to airports across Asia, with jet and kerosene forming a large share of refinery output and more than 80% of combined gasoil and gasoline exports flowing to neighboring markets.

Forecasts suggest that while Singapore’s total oil products demand may peak toward the end of this decade, jet fuel consumption is set to rise further as its role as a regional aviation hub strengthens. This means that any disruption in upstream crude or LNG flows, or significant loss of Chinese export barrels, quickly translates into margin pressure and supply anxiety for airlines and airport fuel buyers.

In this context, secure access to Jet A1 cargoes at established hubs like Jurong, backed by credible suppliers and clear quality control, is more than a trading opportunity—it is a risk management tool for the aviation ecosystem.

For many traders and end‑users, shifting the point of title and risk to FOB at Jurong or similar hubs is an effective way to manage the current environment. By buying EN590, Jet A1, and other products FOB in Asia.

3. Jurong and Asian Hubs: Strategic Platforms in a Fragmented Market

Singapore’s Jurong Island has cemented its position as Asia’s primary refined‑products gateway, with high tank density, developed logistics, and an efficient regulatory environment. In 2025, marine fuel sales at Singapore reached an all‑time high, supported by record port activity and robust fuel offtake, underscoring the city‑state’s central role in regional energy flows. Refined products such as jet fuel, kerosene, gasoline, and diesel are produced at large scale, with a significant portion exported to regional markets including Indonesia and Vietnam.

Beyond Singapore, other Asian and Middle Eastern hubs —Fujairah in the UAE, for instance— act as strategic storage and staging points for diesel, marine fuels, and jet, bridging Middle Eastern refineries with Asian demand centers. Industry analyses for 2025 highlight Rotterdam, Fujairah, and Jurong as the three dominant ports for EN590 transshipment and tank‑to‑tank deals, each with distinct profiles in storage cost, compliance environment, and logistics speed.

Key features of Jurong and similar hubs

• High storage capacity and tank availability for diesel, jet, and other refined products.

• Established quality control processes, including independent inspection and dip‑test procedures, that support international compliance.

• Deep, liquid trading ecosystems where FOB deals, dip‑and‑pay structures, and short‑haul regional deliveries coexist.

For market participants trying to de‑risk their exposure to Hormuz, these hubs are natural focal points: they allow buyers to lift product closer to final demand, reduce voyage exposure through contested waters, and access diversified supply sources.

CIF transactions allows cargoes of EN590, Jet A1, and other refined products to be redirected to markets where netbacks are strongest, aligning with volatile regional price differentials.

4. FOB Jurong: A Practical Hedge Against Hormuz Risk

For many traders and end‑users, shifting the point of title and risk to FOB at Jurong or similar hubs is an effective way to manage the current environment. By buying EN590, Jet A1, and other products FOB in Asia, counterparties can:

• Avoid the most vulnerable leg of the supply chain by taking product that has already reached a secure regional hub.

• Optimize freight selection, chartering vessels and routing that best match their risk appetite, insurance constraints, and delivery windows.

• Gain flexibility in destination—particularly valuable when demand patterns are shifting rapidly between markets like Indonesia, Vietnam, India, and Northeast Asia.

Jurong is especially suited to this model. Its position as a refined‑product hub, not just a transshipment point, means that buyers can access a spectrum of products—EN590 for road and industrial use, Jet A1 for aviation, and other middle distillates—under consistent operational standards. High tank density and established inspection protocols facilitate dip‑and‑pay and other structured FOB transactions, which are familiar to institutional buyers.

In a market where Europe is still the largest EN590 consumer but Asia is increasingly premium‑constrained, sourcing compliant diesel FOB in Jurong lets Asian buyers secure needed volumes without competing directly in European hubs or relying on Hormuz‑exposed flows.

For them, access to EN590 and Jet A1 from external hubs can be a tactical tool to manage planned maintenance, unplanned outages, or demand spikes.

5. CIF ASWP: Extending Optionality Beyond Asia

While FOB deals at Jurong and other Asian ports address immediate regional needs, many traders and integrated companies require global flexibility. CIF (Cost, Insurance, Freight) transactions on an ASWP (Any Safe World Port) basis provide that optionality by bundling freight and insurance into the delivered price and allowing discharge at a wide range of safe ports, subject to contractual terms.

In the current crisis, CIF ASWP structures offer several advantages:

• They shift voyage management, routing, and insurance procurement to the seller, which can be especially valuable for buyers that lack in‑house shipping desks or want to limit operational exposure.

• They allow cargoes of EN590, Jet A1, and other refined products to be redirected to markets where netbacks are strongest, within the agreed ASWP parameters, aligning with volatile regional price differentials.

• They help end‑users in non‑Asian markets, or those with diversified portfolios, to secure supply without being locked into a single route through Hormuz or any other chokepoint.

For Asian buyers specifically, CIF ASWP cargos offer insurance against local disruptions. If port congestion, regulatory changes, or demand shifts make a planned discharge point suboptimal, the flexibility embedded in ASWP clauses can provide alternative options, subject to freight economics and contractual consent.

FOB Jurong supply of EN590, Jet A1, and other derivatives, complemented by CIF ASWP cargoes, is one of the clearest ways to reduce exposure to Hormuz while keeping product moving to where it is needed most.

6. Why Structured EN590 and Jet A1 Supply Matters Now

6.1 For traders

Traders face a volatile pricing environment where benchmarks reflect not only fundamentals but also headline risk around Hormuz. EN590 price spreads between Rotterdam, Fujairah, Jurong, and Asian ports are moving in response to refinery runs, freight, and risk premia. Access to consistent FOB and CIF supply—anchored in liquid hubs such as Jurong—creates arbitrage opportunities while containing operational risk.

By working with established suppliers, traders can:

• Build structured books that balance long FOB positions in Asia with CIF ASWP sales into deficit markets.

• Hedge geopolitics by diversifying route and origin exposure.

• Offer more reliable physical performance to their own clients, strengthening commercial relationships during a stressed period.

6.2 For refiners and distributors

Refiners and fuel distributors in Asia are grappling with changing crude slates, constrained LNG supply, and an uneven pace of demand recovery across sectors. For them, access to EN590 and Jet A1 from external hubs can be a tactical tool to manage planned maintenance, unplanned outages, or demand spikes.

Jurong and similar hubs allow them to:

• Backfill domestic shortfalls with prompt cargoes.

• Blend and redistribute product across regional markets.

• Maintain service levels to retail, aviation, and industrial clients even if local refinery runs are suboptimal.

6.3 For airlines and major end‑users

Airlines, logistics operators, and large industrial consumers are at the sharp end of both price and availability risk. Southeast Asian aviation fuel demand is expected to grow at a compound rate through 2033, while Singapore’s role as an aviation hub intensifies. In this environment, supply interruptions or quality issues can rapidly translate into operational disruption.

Structured Jet A1 supply, backed by reliable storage and inspection at hubs like Jurong and delivered via FOB or CIF ASWP arrangements, allows these end‑users to secure physical molecules while preserving some flexibility in logistics and timing.

7. Looking Ahead: From Crisis Response to Strategic Realignment

The current Hormuz crisis is a reminder that Asia’s energy security challenge is fundamentally about chokepoints and concentration risk. As long as such a large share of oil and LNG imports is funneled through a single narrow strait, geopolitical tensions will periodically threaten supply chains and macroeconomic stability.

Over the medium term, Asia will continue investing in diversification: more LNG and refined‑product hubs, additional pipeline capacity where feasible, nuclear build‑out in selected markets, and a gradual acceleration of renewables. But even under optimistic scenarios, oil and gas will remain central to the region’s energy mix for years, and refined products like EN590 and Jet A1 will stay critical for transport and aviation.

In this transitional period, the practical question for traders, suppliers, and decision‑makers is not whether to use refined‑product hubs and structured deals —but how to integrate them systematically into their risk management and procurement strategies. FOB Jurong supply of EN590, Jet A1, and other derivatives, complemented by CIF ASWP cargoes, is one of the clearest ways to reduce exposure to Hormuz while keeping product moving to where it is needed most.

Conclusion

Asia’s energy system is confronting a dual shock: acute geopolitical risk around the Strait of Hormuz and tightening regional balances for key refined products. The crisis has exposed vulnerabilities in traditional crude and LNG supply chains, accelerated policy responses, and intensified competition for diesel and jet fuel barrels across the region.

Against this backdrop, the role of Asian refined‑product hubs—particularly Jurong—has become more central than ever. By leveraging FOB supply of EN590, Jet A1, and other derivatives in these ports, and by structuring CIF transactions on an ASWP basis, traders and end‑users can materially reduce their dependence on Hormuz‑exposed flows while maintaining, and in some cases enhancing, their commercial flexibility. For Enerdealers’ readers—traders, suppliers, and decision‑makers across the energy value chain—the message is clear: in a world where chokepoints and politics are shaping markets as much as geology and demand, access to reliable FOB and CIF refined‑product supply in Asia is no longer optional; it is a core component of resilient strategy.
