Chinese Automaker BYD Surpasses Toyota in Key Southeast Asian Market

China's BYD surpasses Toyota in Thailand, fueled by soaring oil prices driving EV demand. While exports surge, domestic sales in China face a prolonged decline.

A significant shift in automotive leadership is underway in Southeast Asia, where China's BYD has achieved a historic milestone by overtaking Toyota. This changing of the guard highlights how geopolitical events are rapidly reshaping the global automotive landscape, even as the company contends with persistent challenges in its domestic market.

International Surge Fueled by Energy Prices

The recent spike in oil prices, triggered by disruptions to shipping routes through the Strait of Hormuz amid tensions with Iran, has acted as an unexpected catalyst for electric vehicle (EV) demand across the Asia-Pacific region. Soaring fuel costs are driving consumers directly toward showrooms of EV manufacturers. BYD is experiencing this surge far beyond a single country, with dealers in markets like Australia, New Zealand, and the Philippines reporting a dramatic influx of customers.

According to CEO Wang Chuanfu, the company is now selling in a single day in these regions what it typically would over a two-week period. Market experts at Bernstein view this situation as a clear strategic advantage. They note that Chinese brands like BYD, with their wide range of affordable electric and hybrid vehicles, are perfectly positioned to benefit from a prolonged period of elevated oil prices. The firm's first-quarter export data underscores this powerful momentum:

• March exports: 120,083 vehicles (a 65% year-on-year increase)
• Q1 2026 overseas sales: 321,165 units
• New 2026 export target: 1.5 million vehicles
• Overseas share of total sales: 40% in March

A Regional Power Shift in Thailand

The fundamental nature of this change was on full display at the recently concluded Bangkok Motor Show, which ended on April 5. At Southeast Asia's most important auto show, BYD secured 17,354 vehicle orders. This figure allowed the Chinese automaker to surpass the perennial leader Toyota, which recorded 15,750 reservations. This dethroning marks a break in the decades-long ironclad dominance Japanese manufacturers have held in the region.

Domestic Headwinds Persist

In stark contrast to its international strength, BYD is facing a noticeable cooldown in its home market of China. While domestic deliveries in March exceeded 300,000 units, indicating a recovery from the previous month, this still represents a year-on-year decline of over 20%. This marks the seventh consecutive month of shrinking domestic sales. Analysts at Citigroup even suggest that the domestic business may have operated at a loss in the past quarter. Furthermore, in battery production, BYD is currently ceding market share to its competitor CATL.

The Path Forward: Localizing Production

To secure its rapid international growth sustainably, BYD is now sharpening its focus on local manufacturing. Industry observers state that the future success of its global expansion depends heavily on how quickly new factories in Hungary, Thailand, and Brazil can ramp up their production capacity. Establishing a robust local manufacturing footprint is seen as the key strategy for BYD to reduce its long-term reliance on exports from China.
