Group 1 - BYD plans to gradually abandon its proprietary supply chain finance platform "Di Chain" over the next 1-2 years, shifting towards more standardized payment methods such as bank acceptance bills, commercial acceptance bills, and cash [1] - "Di Chain" has supported BYD's expansion for ten years, providing a digital voucher system for accounts receivable management and factoring financing services to over 10,000 suppliers [1] - The transition is driven by compliance issues, high discount costs for suppliers, and accumulated hidden debts, alongside tightening regulatory policies [1] Group 2 - In September 2025, the Ministry of Industry and Information Technology and other departments issued a plan to ensure key automotive companies adhere to payment commitments and establish payment norms for supplier accounts [2] - BYD's financial report shows that as of September 2025, its accounts payable amounted to 222.8 billion yuan, with only 22.2 billion yuan in payable bills, representing just 0.62% of total payables [2] - Recent data indicates a significant increase in BYD's issuance of commercial bills, with amounts of 2.7 billion yuan, 2.3 billion yuan, and 4.5 billion yuan in the last three months of 2025, reflecting a commitment to reduce "Di Chain" usage [2] Group 3 - Bills are widely recognized in commercial activities due to their dual attributes of "credit + circulation," serving as a written certificate for unconditional payment [3] - The fundamental function of bills is payment, providing a safer and more flexible alternative for large transactions compared to cash, especially beneficial for companies facing cash flow challenges [5] - Bills can also serve as a financing tool, allowing companies to discount them with financial institutions for immediate cash flow needs [6][7] Group 4 - The credit attribute of bills acts as an "invisible business card" for companies, where the acceptance of a bill depends on the issuer's credit rating [8] - Long-term stable use of bills can enhance a company's credit record, leading to better payment terms and lower barriers for future transactions [8] Group 5 - Risks associated with bills include the potential for forgery and alteration, particularly with traditional paper bills, as well as the risk of non-payment if the issuer's credit fails [9] - Operational risks arise from non-compliance with legal requirements in the creation and transfer of bills, which can render them invalid [9] - Understanding bills as standardized financial tools can enhance the financial security and operational stability of companies within the supply chain [10]

Core Viewpoint - BYD is shifting its payment strategy by reducing the use of D-chain and increasing the proportion of cash and bill payments starting from Q4 2025 [1][8] Group 1: Accounts Payable Situation - As of September 2025, BYD's accounts payable balance was 222.8 billion yuan, with other payables at 134.8 billion yuan, and the payable bills balance was only 2.22 billion yuan, accounting for just 0.6% of total payables [2][9] - If the proportion of payable bills increases to 20%, the balance could rise to 70 billion yuan, including both bank and commercial bills, compared to SAIC Group's bill proportion of around 25% [2][9] Group 2: Commercial Bill Issuance - In the first half of 2025, BYD issued only 910 million yuan in commercial bills, with 680 million yuan in Q3; however, starting in October, the issuance significantly increased, with 2.75 billion yuan in October, 2.31 billion yuan in November, and 4.49 billion yuan in December [10][2] - By the end of December 2025, the balance of commercial bills accepted by BYD reached 8.37 billion yuan, an increase of 3.59 billion yuan from November and 7.55 billion yuan from September [5][12] Group 3: Future Projections - The average monthly issuance of commercial bills in Q4 2025 was around 3 billion yuan; if this level is maintained in 2026, the acceptance balance could grow to approximately 16 billion yuan, representing about 5% of BYD's accounts payable [7][14]
