BYD has become one of the most influential companies in the global electric vehicle market. Its rise has been built on scale, cost control, battery expertise, and a highly integrated manufacturing model. The company has moved from a domestic Chinese champion to a global competitor challenging established automakers and Tesla. Yet its next phase will not be defined only by vehicle sales, overseas factories, or new technology. It will also depend on how sustainably the company finances growth.
In June 2025, BYD pledged to pay suppliers within 60 days. The decision followed pressure from Beijing, which has been targeting long payment cycles and aggressive cost pressure across China’s automotive supply chain. For BYD, this was more than a supplier relations issue. It marked a significant financial reset, because the company had long relied on supplier payment structures as an important source of working capital. The pledge therefore changed not only how BYD deals with its partners, but also how investors assess its balance sheet and cash flow quality.
A Growth Model Built on Supplier Credit
During its rapid expansion, BYD used money owed to suppliers as a form of low-cost financing. This helped the company support production growth, research and development, and capacity expansion during a period of intense EV market growth. The model gave BYD flexibility and helped it compete aggressively in a sector marked by price pressure and fast product cycles. However, it also transferred part of the financial burden to suppliers, especially smaller component makers with less access to cheap credit.
Some suppliers reportedly faced payment cycles of around 300 days under BYD’s internal system, known as Di Lian. Chinese media estimates suggest that as many as 10,000 companies may have been paid through this structure in recent years. Long payment terms are common in China’s automotive sector, but BYD’s scale made the issue especially important. When the largest EV maker changes its payment practices, the impact is not limited to one company. It can influence expectations across the wider industrial supply chain.
Borrowings Rise as the Balance Sheet Changes
BYD is now moving away from promissory notes and toward conventional bank notes and cash payments. This transition is visible in its financial statements. Total borrowings rose to Rmb113.4 billion in 2025, compared with Rmb28.5 billion a year earlier. In the first quarter of 2026, short-term borrowings increased further to Rmb66 billion, up from Rmb38 billion at the end of 2025. Notes payable also rose sharply to Rmb48.6 billion, almost 20 times the 2024 level.
These figures do not automatically signal financial weakness. They show that liabilities previously managed through supplier payment structures are being converted into more formal financing instruments. This makes BYD’s funding model more transparent, but it also changes how the market evaluates the company. Investors will now focus more closely on debt structure, operating cash flow, payment discipline, and the true cost of expansion.
Cash Flow Pressure Meets Global Expansion
The timing of this financial shift is critical. BYD is investing heavily outside China, with factories under development in Hungary, Brazil, Indonesia, Thailand, Turkey, and Uzbekistan. The company is also building its own fleet of eight ships to transport vehicles from China to overseas markets. These projects support a clear international strategy, but they also require significant capital at a time when the company is adjusting its supplier payment model.
Operating cash flow has already come under pressure. It fell to Rmb59.1 billion in 2025, down from Rmb133.4 billion a year earlier. The trend continued in the first quarter of 2026, when operating cash flow reached Rmb2.8 billion, compared with Rmb8.6 billion in the same period of 2025. This creates a strategic challenge for BYD. The company must finance global expansion while also reducing its reliance on supplier credit.
Beijing’s Anti-Involution Policy Takes Effect
BYD’s payment shift also reflects a broader change in China’s industrial policy. Beijing has been pushing back against excessive competition, price wars, and financial pressure on suppliers. This approach is often described as an “anti-involution” policy. The goal is to make growth more sustainable across the industrial ecosystem, rather than allowing leading companies to expand by transferring pressure down the supply chain.
The EV sector is central to this policy direction. China has achieved global leadership in electric vehicles, but rapid growth has also created overcapacity risks, margin pressure, and weaker bargaining power for suppliers. BYD’s current payment cycle is reported at 123 days, four days shorter than a year earlier but still far from Beijing’s 60-day target. The direction of travel is clear, but the adjustment is still incomplete.
What This Means for the EV Sector
BYD remains a highly competitive company with strong manufacturing scale, battery capabilities, and access to financing. It also has significant global ambitions. The company made 1 million overseas sales last year, is targeting 1.5 million this year, and has a longer-term ambition of 5 million. These goals show that BYD is not slowing down. Instead, it is entering a more capital-intensive stage of growth.
The wider lesson is important for the EV industry. Market leadership is no longer only about producing more vehicles at lower cost. It also requires transparent financing, resilient suppliers, disciplined capital allocation, and sustainable international expansion. BYD’s supplier payment reset may appear technical, but it is a major signal for the next phase of China’s EV industry. The companies that win globally will need not only scale, but also stronger financial foundations.
