BYD's Record Export Haul Runs Into a Widening Regulatory Net

BYD closed at EUR 8.81, down 7.2% for the week with an RSI of 30.8, as Thailand raised EV import taxes and US and EU scrutiny mounted.

BYD closed Friday at EUR 8.81, a print that leaves the Chinese automaker roughly 29% below its October 52-week peak and about 15% under its 200-day moving average. The stock managed a 1.2% gain on the day but still finished the week down 7.2%, with a relative strength index of 30.8 placing it firmly in oversold territory. Behind that subdued tape sits a company delivering some of its strongest overseas numbers to date while simultaneously drawing fire from regulators and politicians on three continents.

Washington Turns Up the Volume

The latest flashpoint came from US Transportation Secretary Sean Duffy, who on Tuesday voiced what Reuters described as "profound concern" over Ford's business ties to Chinese companies, naming BYD, CATL and Geely specifically. By Wednesday, Republican lawmakers in Congress had amplified the criticism, taking aim at Ford's partnerships with Chinese suppliers and manufacturers. A letter from Duffy to Ford chief executive Jim Farley pressed the American automaker to sever those relationships on national security grounds.

The pressure is indirect for BYD, which has minimal presence in the US market, but it signals a hardening posture toward Chinese automakers operating anywhere near American supply chains.

Thailand Adds a Concrete Cost

Far more tangible for BYD's bottom line is a decision out of Southeast Asia. Thailand's electric vehicle board approved an increase in consumption tax on imported EVs on Thursday — a move Reuters explicitly framed as a potential barrier to market entry for foreign manufacturers, BYD included. Thailand ranks among the most important Southeast Asian markets for Chinese electric vehicles, giving the measure considerably more weight than a passing regulatory note.

Export Machine Keeps Humming

These regulatory pinpricks land against a backdrop of extraordinary overseas momentum. BYD's August sales climbed 17.8% to 440,293 vehicles, with overseas deliveries surging 134.5% to 189,466 units — the fourth consecutive month of global growth. The broader Chinese picture was equally striking: the China Passenger Car Association reported Tuesday that national passenger vehicle exports jumped 77.5% to a record 894,000 units in August, a haul BYD helped drive, according to Reuters.

That export engine matters all the more because demand at home remains soft, making foreign markets the primary growth lever for the entire Chinese industry.

Beijing Tightens the Reins

Paradoxically, Beijing is simultaneously raising the bar for the very expansion it has championed. In early September, China's Ministry of Commerce, the Ministry of Industry and Information Technology and the market regulator jointly stiffened rules governing overseas activities by domestic automakers. The new requirements cover foreign investment, local operations, antitrust compliance, anti-corruption measures and social responsibility. Reuters drew a direct line between the tightening and the rapid international push led by BYD — a signal that policymakers intend to hold their flagship company to a higher standard even as it flies the flag abroad.

Europe Becomes the Next Battleground

Competitive pressure is building in Europe as well. Volvo Cars and Geely Auto Group finalized an agreement on Thursday making Volvo the exclusive European distribution partner for Lynk & Co starting January 2027. Reuters placed the deal in the context of brutal competition in China's home market, which is pushing manufacturers like BYD to expand into Europe.

Meanwhile, Italian supplier lobby Anfia is calling for an EU tariff of 80% on Chinese vehicles and components above certain thresholds — a demand that underscores just how seriously European industry players view the export strategies of Chinese manufacturers.

A Two-Sided Investment Case

For investors, the picture splits cleanly. Operationally, BYD continues to post robust figures, with overseas business expanding far faster than the overall market. Politically, risks are compounding — from Washington's scrutiny of Ford's partnerships to potential tariff action in Europe and fresh tax hurdles in Thailand. The coming weeks will reveal whether operational strength can outrun the mounting regulatory drag, or whether pressure from multiple directions finally slows the pace.
