## How they are linked

### 1. Price link: demand driver

*Cost and price · Weak · Both ways*

Vehicle output and tyre replacement drive most butadiene use. Yet the vehicle price proxy barely moves with the petrochemical proxy, -0.06 monthly, because car prices are set by model cycles and competition, not by monthly input costs.

- **-0.06** monthly change correlation
- **-0.08** 12-month change correlation
