Oil Shock and Battery Bottleneck: BYD's Dizzying Export Growth Meets Domestic Headwinds

A sustained spike in crude prices, driven by escalating military strikes on Iran, has turned European car buyers toward electric vehicles at record pace—and no manufacturer is reaping the rewards quite like BYD. With Brent holding above $100 a barrel since late February, EV registrations across 16 core European markets jumped 34 percent year-on-year in April. That surge has lifted BYD's overseas sales to an all-time monthly high of 135,000 vehicles in the same month, a 70 percent jump from a year earlier. Over the first four months of 2026, the Shenzhen-based group exported roughly 456,000 units and has lifted its full-year target to 1.5 million.

The contrast with BYD's home turf could hardly be sharper. China's price war hammered first-quarter net profit, which collapsed 55 percent to around $597 million. While the international business booms, domestic margins are being squeezed by a brutal contest that management hoped to escape by pushing into the premium segment—a move that has encountered early turbulence.

BYD's luxury sub-brand Denza has seen retail sales in China slide roughly 41 percent in the first four months of the year, despite the launch in May of a revamped flagship SUV priced at nearly 410,000 yuan. The company notes that 70 percent of new Denza buyers had previously owned a BMW, Mercedes-Benz or Audi, underlining its ambition to chip away at German dominance. Yet home-grown rivals such as Zeekr and Voyah are applying fierce pricing pressure, forcing BYD to accelerate its European rollout. Denza has already entered five major European markets, including Germany, France and the UK, and plans to be present in 30 countries by year-end.

Should investors sell immediately? Or is it worth buying BYD?

The European appetite for BYD models is nowhere more visible than on Carwow, Germany's leading car-buying platform, where purchase inquiries soared 25,000 percent in the first quarter. Carwow Deutschland managing director Philipp Sayler von Amende describes the momentum as remarkable, noting that BYD has vaulted from a niche player to one of the most sought-after brands. In the UK, it became the best-selling EV marque in April, overtaking Tesla, Kia and every large European manufacturer.

That demand is colliding with supply constraints. BYD's new Great Tang electric SUV, unveiled at the Beijing auto show, pulled in over 100,000 pre-orders almost immediately. But deliveries have been pushed back to June 8, with several dealers yet to receive their first batches. The bottleneck sits squarely inside BYD's own battery supply chain: the second-generation Blade battery, capable of charging from near-empty to full in just nine minutes, is in such high demand that production capacity cannot keep pace. Chairman Wang Chuanfu has acknowledged that capacity expansion has hit a wall.

The production logjam is punishing BYD's stock. Shares in Hong Kong trade at roughly HK$91, hovering near the lowest point of their 52-week range. The first-quarter profit collapse spooked investors, and the ongoing uncertainty about whether battery output can ramp up fast enough to clear the order book has kept buyers on the sidelines. Goldman Sachs, however, sees the current valuation as a trough, maintaining a "Buy" rating with a 12-month price target of HK$134. The consensus from 25 analysts stands at HK$124.

BYD is investing heavily to ensure European growth does not stall. A new plant in Hungary is already testing vehicles, and a $1 billion factory in Turkey is slated to go live before the end of 2026. The big question lingering over the boardroom is how much of the continental EV boom is structural and how much is purely a function of expensive petrol. Should oil prices ease, the surge in orders could ebb—making it all the more urgent for BYD to resolve its battery bottleneck and deliver the premium margins it has long promised.
