Thai Summit's Chanaporn Rungruengkit argues Thai-owned part makers are losing ground: Thai firms' share of BOI investment promotion fell from 41% to 25%, and auto SME special-support projects dropped from 14 in 2024 to 1 in 2025. She says Indonesia and Vietnam are pressing Thailand's production base and that local suppliers face price pressure from few buyers. If you supply auto makers or Tier-2 parts, expect tighter pricing and check whether you qualify for any remaining SME support programmes.
