China's electric vehicle (EV) sector is in turmoil due to a price war, with BYD losing $21.5 billion in market value since May 2024. Weaker demand and overcapacity have led to a significant decline in profits, prompting government intervention and a wave of market consolidation, as more brands exit than enter. BYD's dual pricing strategy allows it to cut domestic prices while maintaining higher margins abroad, leveraging vertical integration for cost advantages. Meanwhile, shifting consumer preferences and low brand loyalty complicate the landscape, as buyers prioritize specifications and price over brand attachment.
