China auto sector Jan-Sep 2026 profit falls 23% as margin hits 3.3%

The divergence between rising revenue and falling profit is the real story here: volumes are softening while costs outpace sales, and the September margin collapsing to a near four-year low suggests the pressure is accelerating rather than stabilizing. That squeeze matters well beyond the automakers themselves — it ripples through the battery, components and materials supply chains that feed the sector, and through the pricing power of every producer in it. Whether the September deterioration is a one-month anomaly or the start of a sustained margin compression is the open question worth watching.
