When crude oil stocks increase, it shows that there is an oversupply of crude oil in the market, which leads to a drop in oil prices, a rise in the dollar and a drop in crude oil.

When the data is less than expected, it is good for crude oil (usually also good for Canadian dollar). When the data is greater than expected, it is bad for crude oil (usually also bad for Canadian dollars). Because when the crude oil inventory is less than expected, it means that the inventory is unexpectedly reduced, that is, the use of crude oil increases, resulting in a decrease in inventory, which is good for crude oil prices. On the other hand, if the inventory increases more than expected, it means an unexpected decrease in usage, which is bad for crude oil prices. When the crude oil inventory decreases, it shows that the market demand for crude oil is strong, which leads to the rise of oil price, the decline of US dollar and the increase of crude oil. Asphalt is the extract of crude oil, which directly affects the price fluctuation of asphalt. If you don't understand anything, you can ask me (165 1? 43446).
