BYD increasingly relies on overseas markets to save the day.

Author | Zhou Zhiyu

The more competitive the domestic auto market becomes, the more BYD needs overseas markets to sustain growth.

This is not to say that BYD is struggling to sell in China. On the contrary, it remains one of the strongest scale players in the domestic new energy vehicle market, but scale and growth have begun to diverge.

On July 1, BYD's June sales figures clearly laid out this change. BYD's monthly sales still exceed 400k units, maintaining its top-tier industry volume; overseas sales have already surpassed 170k units, accounting for about 40% of the total. Calculating backward based on this metric, domestic sales were roughly around 230k units.

This means that BYD's high monthly sales are no longer mainly driven by the domestic market but increasingly rely on overseas markets to fill the growth.

Over the past few years, BYD's growth in China has benefited from three tailwinds: the rapid increase in new energy penetration rate, the explosion of plug-in hybrids, and cost reduction through vertical integration. But entering 2026, the pressure in the domestic market has obviously become tougher.

Currently, price competition has not stopped. The main price range of 100k to 200k yuan is BYD's traditional stronghold and also the most crowded and sensitive battlefield in China's auto market. In this price range, Geely, Changan, Chery, Leapmotor, and XPeng are all accelerating their new energy product offerings, and joint venture brands are also counterattacking with lower prices and Chinese supply chains. BYD can still maintain its volume, but the marginal benefit of continuing to trade price for scale is declining.

The high growth of the new energy market is also turning into a battle for existing stock. A few years ago, BYD only needed to convert fuel vehicle users to DM-i and EVs to benefit from industry expansion. But now that the new energy penetration rate is at a high level, the competition among automakers is no longer just about 'fuel to electric' conversion, but about who snatches orders from whom.

That is why in the June data, what really stands out is not whether BYD can still sell 400k units, but that the overseas share has risen to a level that cannot be ignored.

BYD has already increased exports to about 40% of sales to hedge against the weakening domestic market.

Overseas used to be a growth story for BYD, but now it is more like a mandatory question in its sales structure.

At the annual general meeting on June 9, 2026, BYD Chairman Wang Chuanfu proposed that BYD hopes to become the world's largest automaker by scale within five years. Supporting this goal is not just batteries, fast charging, and product costs, but more importantly, overseas production capacity and overseas sales networks.

Its overseas sales target for 2026 is 1.5 million units, up from 1.05 million in 2025. Now, with overseas sales exceeding 170k units in June, BYD is pushing forward globalization at a more aggressive pace.

This is crucial for BYD.

The more competitive the domestic market, the higher the profit and strategic value of overseas markets. The new energy penetration rate, product supply, and intensity of price competition in markets such as Europe, Southeast Asia, and Latin America are not at the same stage as China. When BYD takes its China-honed capabilities in batteries, plug-in hybrids, cost control, and fast charging abroad, it still has a dimension-reducing product advantage.

But overseas is not a simple export business.

BYD has moved from 'selling cars abroad' to 'must stay local'. European tariffs, US market barriers, local manufacturing requirements, distribution systems, after-sales service, and charging networks will all turn globalization from a sales issue into an organizational issue.

BYD's European focus has shifted to the Hungary factory and paused progress on the Turkey factory, prioritizing resources for local production within the EU. This shows that BYD itself understands that the larger overseas sales become, the less it can rely solely on spillover from Chinese factories.

BYD's current contradiction is that it already has the sales ambition of a global automaker, but its organization and brand are still catching up on globalization.

In China, BYD exerts strong dominance through scale, supply chain, and price efficiency. But overseas, the rules are much more complex. The European market values brand, channels, and compliance; Southeast Asia depends on local partners and policies; Latin America tests financial services and supply stability; the US market is almost blocked by geopolitics and tariffs.

More importantly, once overseas markets shift from a nice-to-have to a growth pillar, the margin for error decreases. 170k units of overseas monthly sales are an achievement as well as a pressure. It means BYD must simultaneously ramp up transportation, inventory, dealer profits, local factory ramp-up, after-sales service, and brand awareness. If any link falls behind, overseas growth will turn into a cost instead.

BYD's domestic foundation is still thick enough; monthly sales of over 200k units remain a scale that other automakers find hard to reach. But judging from the June data, its growth narrative has changed: the domestic market supports the floor, and the overseas market determines the ceiling.

For BYD, the most critical question for the next stage is not whether it can continue to be number one in China, but whether it can truly transform its Chinese-style scale capability into global operational capability.

For Wang Chuanfu, the goal of becoming the world's largest automaker is no longer just about production capacity, cost, and technology, but a cross-market test of organizational capability. The more BYD sells overseas, the more it must prove that it is not just an automaker that is best at price wars in the Chinese market, but can also become a truly global automaker.
