Vietnam braces for flight cuts from April after China, Thailand ban jet fuel exports

Vietnam imports more than two-thirds of its jet fuel, with 60% sourced from China and Thailand, and faces risks of jet fuel shortages from early April after China and Thailand halted refined fuel exports. Major importers can only guarantee supplies through March and have urged airlines to restrict routes; Hanoi advised seeking alternative suppliers though finding new sources is difficult. Front-month jet fuel swaps in Singapore trade around $157/bbl, >1.5x pre-conflict, and importers warn rising prices are straining credit lines and could make many routes unprofitable.

Analysis

This is a classic supply-constrained shock with a concentrated supplier base and short lead times — the immediate transmission is soaring jet-kerosene cracks versus crude, straining airline P&Ls and importers' working capital. With front-month jet swaps ~1.5x pre-shock, refiners and traders with access to flexible product slate and freight capacity can capture outsized margins for weeks, while airlines face forced capacity rationalisation that will amplify ticket yield volatility on domestic routes.

Second-order winners include Asian refiners with exportable spare kerosene capacity and integrated logistics players (tankers, leased storage) able to monetise contango and forward cover; losers are under-hedged regional carriers and fuel distributors hitting credit lines. The banking angle is underappreciated: importers flag near-term credit saturation, so short-term liquidity provision or structured prepay facilities to importers/refiners can offer premium returns with collateralised upside to the jet crack.

Key catalysts and timeframes: a diplomatic unwind or formal lifting of Chinese/Thai export bans can normalise flows within 2–6 weeks; alternative supply ramp (India/Korea/Japan) and refinery yield shifts take 4–12 weeks to materially relieve spreads. Demand-side reversals (route cancellations, fare hikes) could compress fuel consumption within a month, capping upside — monitor flight level data and bank liquidity lines for importers as early warning indicators.

Key Decisions for Investors

• Short VJC.HM (VietJet) and HVN.HM (Vietnam Airlines) via puts or borrowed stock, 1–3 month horizon. R/R: if airlines cut domestic routes and fuel remains elevated, expect 20–40% downside in equities; tail risk is a quick diplomatic resolution or emergency state support — stop-loss at 12–15%.
• Buy NYMEX ULSD (HO) 1–2 month call spreads (e.g., buy HO front-month call, sell 2nd month call) to play near-term spike in middle distillates/jet cracks. R/R: limited premium outlay with asymmetric payoff if supply disruptions persist; hedge by shorting a light crude future (CL) to isolate kerosene crack exposure.
• Long refining/export optionality in India — RELIANCE.NS or IOCL.NS, 1–6 month horizon. R/R: refiners with spare jet yield and export logistics can capture widened jet crack (10–25% upside potential); risks: freight/logistics bottlenecks and domestic policy interventions.
• Provide short-term, asset-backed financing to major Vietnamese importers (e.g., Petrolimex counterparties) or participate in commercial-paper tranches at elevated spreads, 1–6 month tenor. R/R: senior secured paper yields materially above policy rates with collateral (fuel/storage); downside if sovereign/banking stress forces moratoria — require legal collateral and expedited exit clauses.
