BYD's Indonesian Plant Fires Up as Export Surge Collides With Home-Market Drag

BYD's globalisation strategy passed another milestone on Wednesday with the official start of production at its factory in Subang, Indonesia — a facility that cost the equivalent of 11.7 trillion rupiah and is designed to build up to 150,000 vehicles a year. The timing is telling: the Chinese electric-vehicle maker is leaning ever harder on overseas markets at the very moment its domestic business is shrinking and Beijing is signalling closer scrutiny of the industry's foreign ambitions.

The operational logic of that pivot was laid bare in August's delivery figures. The company sold 440,293 new-energy vehicles last month, its best-ever monthly tally and a 17.84 percent improvement on the same period a year earlier. It marked the fourth consecutive month of year-on-year growth. But the engine of that expansion is unmistakably external: overseas sales surged 134 percent from a year earlier to a record 189,466 units, while cumulative exports for the first eight months of 2026 reached 1,162,260 vehicles — up 85.72 percent. International deliveries now account for 43.56 percent of total NEV sales year-to-date.

The home front tells a very different story. Domestic sales fell 32.72 percent over the January-to-August period to 1,505,755 units, dragging cumulative NEV deliveries down 6.84 percent to 2,668,015 vehicles. That headline decline, however, masks meaningful improvement: the first-half shortfall of 15.72 percent has narrowed considerably, suggesting the export boom is progressively offsetting domestic weakness even if it has not yet fully closed the gap.

The financial picture mirrors that bifurcation. In the second quarter, profit climbed 29.8 percent to 8.2 billion yuan, snapping a run of four consecutive quarterly earnings declines. Yet the first half as a whole still showed a net profit drop of 20.54 percent to 12.32 billion yuan, with revenue off 7.13 percent at roughly 344.815 billion yuan. Notably, overseas revenue of 181.3 billion yuan in the first half exceeded Greater China sales for the first time, accounting for 53 percent of total turnover — a threshold that underscores just how far the company's centre of gravity has shifted.

A regulatory shadow over the expansion

The Indonesian launch is not happening in a policy vacuum. On Tuesday, Chinese regulators issued new guidelines requiring automakers to comply with rules governing outbound investment while strengthening antitrust and anti-corruption measures. Reuters framed the guidance as a direct response to the rapid global expansion led by BYD. No concrete restrictions have yet materialised, but the signal from Beijing is clear enough: the industry's overseas push will face closer official attention from here on.

That adds a fresh layer of uncertainty to a share price already under pressure. The stock trades at around 9.43 to 9.50 euros, roughly 24 to 25 percent below its 52-week high of 12.49 euros set in early October. The recent slide has been steady rather than dramatic — a 6.4 percent decline over the past seven trading sessions and 9.1 percent over the last 30 days. Technical indicators point to persistent weakness: the RSI sits at 39.6, the price is 8.8 percent below its 200-day moving average and 2.1 percent under the 50-day average.

Investors have also had to weigh an unconfirmed Bloomberg report that BYD is exploring the acquisition of a Stellantis plant in Canada — a deal that remains far from certain. The company's model offensive, meanwhile, continues apace. The Sealion 08, positioned as the flagship of the Ocean line with pricing between 230,000 and 280,000 yuan, is scheduled for market launch on September 2, while the Denza brand will introduce the battery-electric N8L, a new powertrain variant of its six-seat SUV, later this month.

The balancing act ahead

The central question for the coming quarters is whether overseas growth can evolve from a compensating force into a durable earnings foundation — or whether regulatory headwinds and domestic pricing pressure will keep the shares stuck in their current downtrend. The bull case rests on momentum: if export volumes continue growing at double-digit rates and quarterly profitability holds steady, the market may increasingly treat China's softness as a bridgeable gap rather than a structural problem.

The bear case is equally visible. Margins could deteriorate again in the third quarter, concrete restrictions on foreign investment could follow the regulatory guidance, or the Subang plant could take longer than expected to ramp toward its 150,000-unit annual capacity. The near-term markers are concrete: utilisation rates at the Indonesian factory over the coming months, early sales figures for the Sealion 08, and ultimately the third-quarter earnings report, which will reveal whether the export boom is translating into sustainable profitability — or remains a high-volume story that the stock market has yet to reward.
