Crude Oil Influence
Since Bitumen 60/70 is a byproduct of crude oil refining, fluctuations in global crude oil prices directly affect its cost. When oil prices rise, the cost of producing Bitumen 60/70 increases, which leads to higher prices in the market. As oil remains a volatile commodity, its impact on bitumen pricing is constant and significant.
Demand and Supply
The balance of supply and demand in different regions also plays a key role in determining the price of Bitumen 60/70. During periods of high construction activity, such as government infrastructure rollouts, demand increases and can drive prices up.
