First, the change of spot asphalt inventory (inventory is a buffer between supply and demand. When the futures price is higher than the spot price, the commercial inventory will increase, thus stimulating the spot price to rise. Instead, it leads to a drop in spot prices)

The second is the market intervention of the Organization of Petroleum Exporting Countries and IEA (they can change the market supply pattern in a short time, thus changing people's expectations of spot asphalt price trends)

Third, exchange rate changes (the price changes of spot asphalt have a negative correlation with the exchange rate changes of the US dollar and major international currencies, and the rise of the US dollar puts pressure on the spot asphalt settled in US dollars. When geopolitics is in turmoil, spot asphalt is positively correlated with the US dollar, and the two complement each other)

If you don't understand, you can ask the age of this work. Division 46=256=29=90 would be better.
