War in Iran Is Already Reshaping East Asia's Energy Future

What It Covers

Alex Turnbull, Singapore-based investor and Australian National University energy security researcher, analyzes how the Strait of Hormuz closure is creating acute energy shortages across East Asia, driving rationing in the Philippines and Vietnam, while accelerating nuclear restarts, EV adoption, and solar-plus-battery deployment across the region.

Key Questions Answered

• •Strait of Hormuz impact on Asian crude pricing: With the Strait effectively closed to normal traffic — down to roughly two ships daily versus typical volumes — Middle Eastern crude loadings now carry spot premiums of $20–$25 above prevailing Brent contracts. Asian refiners in the Philippines and Vietnam are operating hand-to-mouth, paying extreme prompt prices to avoid costly refinery shutdowns.
• •EV demand acceleration as energy security hedge: BYD inventory at dealerships across Australia, Singapore, and broader Asia has dropped from 25-plus days on lot to single-digit days. Demand now outpaces supply, meaning the binding constraint is manufacturing capacity, not consumer appetite. Energy insecurity is converting price-sensitive buyers into EV purchasers faster than any policy incentive achieved previously.
• •Solar-plus-battery storage crushes gas price-setting power: Australia's rollout of residential batteries networked into grid bidding has collapsed intraday electricity price spreads by preventing gas peaker plants from setting marginal prices. The UK has comparable renewables but lacks storage, so gas still prices the market. The actionable lesson: storage deployment, not generation alone, determines whether renewables reduce consumer energy costs.
• •Nuclear restart momentum in Japan and South Korea: Japan is accelerating nuclear plant restarts beyond prior cautious timelines, backed by strong public polling support and a pro-nuclear prime minister. South Korea is following a parallel path. Energy crises convert nuclear from a politically difficult option into a matter of national necessity, compressing timelines that previously stretched across decades of regulatory hesitation.
• •US LNG growth story faces structural limits: Gas turbine costs have risen from roughly $1,000 to over $2,500 per kilowatt, pricing many Asian buyers out of gas-fired power infrastructure. Combined with demonstrated supply chain vulnerability from Hormuz disruptions and Houthi Red Sea threats, Asian governments are reassessing whether building LNG-dependent grids represents acceptable long-term risk, regardless of US export terminal expansion.
