2. Sudden major political time (spot natural gas has the attributes of strategic materials in addition to general commodity attributes, so it is influenced by political forces and political situation).
3. The Organization of Petroleum Exporting Countries and IEA intervene in the market (they can change the market supply pattern in a short time, thus changing people's expectations of spot natural gas price trends).
4. In the international capital market, hot money flows out or in (when the global financial market lacks investment opportunities, they flood into the international commodity market, especially the spot natural gas market, which inevitably pushes up the international oil price and seriously deviates from the fundamentals).
5. Exchange rate changes (the price changes of spot natural gas are negatively correlated with the exchange rate changes of the US dollar and major international currencies, and the rise of the US dollar puts pressure on spot natural gas settled in US dollars. When geopolitics is in turmoil, spot natural gas is positively correlated with the US dollar, and the two complement each other)
6. Abnormal weather (abnormal weather may damage the spot natural gas production facilities, lead to supply interruption, and thus affect the oil price)
7, interest rate changes (when the interest rate increases, the capital investment will decrease, resulting in a smaller initial mining scale; High interest rates will also increase the capital cost of alternative technologies, leading to a decline in mining speed)
8, tax policy (when the tax increases, it will reduce the net profit of spot natural gas exploitation, and correspondingly reduce the enthusiasm of the mining period. And taxes will reduce the return on investment of newly discovered reserves)
