The increase of crude oil price and refinery cost will lead to the increase of glass manufacturing cost. Because crude oil is one of the important raw materials in the glass manufacturing process, glass manufacturers need to buy crude oil to produce glass products. If the price of crude oil rises, the purchasing cost of glass manufacturers will also increase, which may lead to an increase in the price of glass futures. In addition, the change of crude oil price may also affect the whole economic environment and market sentiment, and then indirectly affect the glass futures price. The rise of crude oil price may mean the increase of global economic activities, which may increase the demand for glass products, thus pushing up the price of glass futures.
