## How they are linked

### 1. Feedstock

*Physical flow · Direct · Crude oil → Purified terephthalic acid*

Purified terephthalic acid is made from crude oil: it is one of the raw materials its production routes start from.

### 2. Price link: feedstock cost

*Cost and price · Strong · Both ways*

Oil sets the cost of naphtha and so of paraxylene, which flows through to PTA. The tie is moderate, 0.20 monthly and 0.67 yearly, as Chinese capacity additions often decide PTA margins.
