The more optimistic scenarios rest heavily on a surge in artificial-intelligence-linked capital expenditure and technology exports. Several global data-center operators and semiconductor supply-chain players have signaled interest in Thailand as a regional hub, drawn by its relatively developed power grid and existing industrial base in the Eastern Economic Corridor.

Government Stimulus Filling a Demand Gap
On the domestic demand side, the Thai government is leaning on its
