Middle Eastern LNG flows are critical for Asia Pacific’s power systems. Among upstream industrial giants, Taiwan is particularly vulnerable to an energy crunch due to its increased reliance on natural gas after the 2025 decommissioning of the Maanshan nuclear plant.
Taiwan’s grid architecture is likely to shield semiconductor fabrication initially, but only by shifting the burden elsewhere. When power reserves tighten, authorities have historically prioritised system stability and strategic industrial users, leaving households and lower-value manufacturers to absorb the higher costs and supply volatility.
Our modelling suggests this resilience is likely to be temporary. Leading-edge fabrication is acutely sensitive to power supply stress: while energy supply prioritisation can protect fabs in the near term, sustained constraints will eventually cut into chip production.
Spillover effects across Asia’s tech-dense supply chains will operate with a lag, so near-term data resilience should not be mistaken for immunity. Robust inventory buffers and the region’s distributed mature-node reliance will cushion the initial energy shock.
Still, replacing Qatari LNG is a tricky supply challenge for the region. Contract terms limit alternative sourcing and spot cargoes are likely to become increasingly expensive. The adjustment is therefore likely to fall mostly on state utilities’ balance sheets, though history suggests industrial output won’t be completely insulated.
