Cold wave weather has intensified people's demand for heating. Recently, the import price of liquefied natural gas in Japan and South Korea is rising, which also makes the shipping price of liquefied natural gas soaring. According to Reuters, in less than a year, the price of LNG shipped to Japan, South Korea and other major importing countries has soared from an all-time low to an all-time high. According to the assessment of S & P global Platts, the provider of commodity and energy market information and benchmark price, the benchmark price of LNG in Asia has risen to US $21.45 per million BTU, about US $0.71 per cubic meter. After 2021, the price has risen by 42%. With the soaring price of liquefied natural gas, the shipping of liquefied natural gas has ushered in the situation of "one ship is hard to get". It is reported that the available capacity of the world's major LNG ships in January and February this year has been almost zero. In the past month, the shipping price of LNG on some routes has fully tripled. At the beginning of this month, BP rented a LNG ship to "pick up" from the United States at a "sky high price" of $350000 a day, setting a new record for the most expensive merchant ship in history.
