Nomura: Domestic Auto Sales Drop 21.6% YoY in May

Overview

This Nomura macro chart alert highlights a pronounced 'cold-domestic, hot-external' pattern in China’s auto market in May 2026. Domestic auto sales declined 21.6% year-on-year, driven by policy withdrawal and tax adjustments, becoming a key drag on economic growth. Although exports remained strong, their limited share prevented full compensation for weak domestic demand, and the domestic-external demand divergence is expected to persist throughout 2026.

Core views

Domestic demand has deteriorated significantly. According to early estimates from the China Passenger Car Association (CPCA), domestic auto sales growth in May may fall to -21.6%, worsening from -20.0% in April and -17.0% in Q1. This trend is primarily driven by two factors: first, the fading catch-up effect following the reduction in the scale of the prior large-scale vehicle replacement program; second, the rise in EV purchase tax from 0% to 5%, which directly dampened some consumer demand. Export performance remains robust but contributes modestly. In April, auto export volume growth accelerated to 84.1% year-on-year, up from 60.7% in Q1. Rising global oil and gas prices have boosted demand for Chinese electric vehicles, and energy-related disruptions have unintentionally conferred a unique advantage on Chinese automakers. However, exports remain insufficient to reverse the overall downturn: in 2025, exports accounted for only 19% of China’s total auto market volume (and 15% by value). Macroeconomic implications are profound. Nomura’s prior analysis indicates the automotive industry accounts for 3.2% of China’s GDP. Sustained weakness in domestic sales will materially drag on overall economic growth. The coexistence of persistent domestic demand weakness and robust export performance reinforces the firm’s view that the divergence between external and domestic demand will widen further in 2026.

Analysis framework

The firm employs a hybrid methodology combining high-frequency data tracking with macro-level contribution decomposition. First, it captures short-term market fluctuations using high-frequency sales data from the CPCA and quantifies the marginal impact of policies (e.g., vehicle replacement subsidies, purchase tax) on demand. Second, it decomposes total demand into domestic sales and exports to assess each component’s contribution to industry performance. Finally, integrating the automotive sector’s GDP weight (3.2%), it estimates the specific magnitude of macroeconomic drag or support stemming from auto consumption weakness—leading to its macro-level conclusion regarding domestic-external demand divergence.

Methodology notes

• Macroeconomic framework

  Industry GDP Weight Transmission Analysis

  By linking changes in the sales volume of a specific sector (e.g., autos) to its share of GDP (3.2%), this method estimates the sector’s specific contribution—or drag—on overall macroeconomic growth. It is a commonly used bottom-up aggregation technique in macro research.

  Domestic-External Demand Divergence Analysis

  Total demand is disaggregated into domestic demand and export demand, with distinct drivers analyzed separately (e.g., domestic demand influenced by policy and taxation; exports shaped by global energy prices and competitiveness), to identify structural contradictions in industry growth.

Key data

• April Auto Export Volume YoY Growth84.1%Accelerated further from Q1 (60.7%)
• Automotive Industry Share of GDP3.2%Nomura’s prior analytical data, used to gauge macroeconomic drag
• 2025 Export Share of Total Sales Volume19%Volume-based; exports cannot fully offset domestic demand decline
• EV Purchase Tax Rate Change0% → 5%Tax rate increase was one key factor suppressing domestic sales in May

Impact & implications

The report concludes that the continued decline in domestic auto sales will directly weigh on China’s economic growth in 2026. Given the sector’s 3.2% GDP weight, this negative impact is substantial. While high export growth is encouraging, it remains constrained by base effects and its relatively small share, rendering it inadequate as the sole pillar supporting industry-wide growth. This marked domestic-external demand divergence implies automakers will face a more complex operating environment, requiring simultaneous navigation of intense domestic competition for market share and overseas opportunities amid evolving risks and challenges.

Risks

• Domestic consumption recovery falls short of expectations, leading to further widening of sales declines
• Escalating global trade friction adversely affects auto export growth
• Energy price volatility alters the global demand logic for Chinese EVs

What to watch

• Month-on-month improvement in domestic auto sales in subsequent months
• Whether new follow-up measures will be introduced for the vehicle replacement subsidy program
• Sustainability of export growth against a high base
