BYD’s Hungarian Probe and China’s New Battery Tax Create a Two-Front Headache
Published on 07/23/2026 at 07:52 | Redaktion boerse-global.de
The political storm swirling around BYD’s Hungarian factory escalated on July 21 and 22, when unannounced inspectors descended on the Szeged site to scrutinize work permits, social security records, and employment contracts. The raids came just days after Péter Szijjártó, the former Hungarian foreign minister who personally negotiated BYD’s investment deal, took up a senior external relations role at the Chinese automaker — a move that has ignited accusations of a classic “revolving door” conflict. Prime Minister Péter Magyar has ordered a sweeping review of all subsidies, tax breaks, and permits granted to BYD in Hungary, though the company has declined to comment publicly.
The affair took a more secretive turn when Hungary’s National Security Committee heard testimony from intelligence officials behind closed doors on July 22. The contents of that session have been classified until December 31, 2051, fueling further unease. A government deputy warned of the risk that classified information could flow to China, noting that BYD’s chairman is a member of the Chinese Communist Party. The committee chairman, however, said no new relevant findings emerged. The Tisza party has made clear that the security concern is not BYD itself, but rather the access an ex-minister with knowledge of state secrets now has while working for the company. Chinese business leaders in Hungary have privately expressed fears that the controversy could taint all Chinese firms operating in the country.
The Szeged plant is strategically vital for BYD: as its first European manufacturing hub, it sidesteps the EU’s 17 percent retaliatory tariff on Chinese-made electric vehicles. BYD has pledged roughly €246 million in research projects tied to the site, covering autonomous driving and powertrain technology. Industry observers now worry the audit could delay production ramp-up.
Should investors sell immediately? Or is it worth buying BYD?
A Second Regulatory Blow from Beijing
While the Hungarian drama unfolds, BYD faces a fresh challenge on home turf. Starting September 1, 2026, China will impose a 2 percent consumption tax on lithium-ion batteries, rising to 4 percent by September 2027. Solid-state batteries are exempt until the end of 2028. For a typical 60-kilowatt-hour vehicle battery, CITIC Securities estimates the added cost at roughly 468 to 936 yuan — a meaningful sum given that China’s auto industry profit margin hovered at just 3.4 percent between January and May 2026. Crucially, batteries produced in-house are exempt, giving vertically integrated manufacturers like BYD a clear edge over rivals that must purchase cells from third parties.
European Expansion Rolls On
Political turbulence aside, BYD’s European offensive shows no signs of slowing. The company is in talks with multiple automakers, including Stellantis, about acquiring an existing European plant — BYD prefers wholly owned factories over joint ventures. The numbers justify the ambition: exports surged to 456,263 vehicles in the first four months of 2026, up from 285,170 a year earlier. In the UK, BYD sold nearly 38,000 vehicles in the first half of 2026, a 95 percent jump that made it the best-selling electric brand. At the Goodwood Festival of Speed, BYD commanded the largest single-brand exhibition space. Chairman Wang Chuanfu reiterated at the June shareholder meeting the goal of making BYD the world’s largest automaker by volume by 2030, with overseas sales exceeding 1.6 million units this year alone. The Denza sub-brand also unveiled the Z9S, an electric sedan boasting up to 1,194 horsepower and a range of 920 kilometers on China’s CLTC cycle.
Global Moves Beyond Europe
BYD’s expansion extends well beyond the continent. At the Shenshan site, the company has launched a hiring drive for more than 9,000 positions, offering monthly salaries between 5,000 and 20,000 yuan. A technology partnership with Xperi will bring DTS AutoStage as the exclusive in-car media platform for BYD vehicles, rolling out in the fourth quarter of 2026 or earlier — making BYD the 14th automaker to adopt a platform already running in over 16 million vehicles across 150 countries. In Kazakhstan, the Astana Group plans to establish BYD passenger-car assembly from 2027, alongside a new domestic bus brand and an expanded fast-charging network. In South Africa, Absa has broadened its BYD financing offering with a rate of prime minus one percent and a residual value guarantee, building on a partnership struck in 2025.
Stock Stays Subdued
The BYD share closed at €9.83 on Wednesday, down 1.38 percent on the day, after touching €9.77 earlier in the session. While the stock has climbed 15.80 percent over the past 30 days, it remains 7.35 percent below its 200-day moving average — and roughly eight percent under that benchmark by another calculation. Despite having rallied sharply from a 52-week low of €8.03, the political uncertainty in Hungary is keeping a lid on sentiment. For now, investors appear to view the regulatory risks in Budapest as secondary to BYD’s operational momentum in Europe and its structural advantage under China’s new battery tax regime. But with the Szeged audit unresolved and classified committee hearings adding to the opacity, the Hungarian affair has become a persistent overhang on a stock otherwise riding a powerful growth narrative.
