It is important to remember that US gas prices do not take into account the final cost to the consumer, including transportation, liquefaction (regasification) costs, insurance, seller profitability. Therefore, the difference by several times from European and Asian prices should not be misleading.

Gas prices in Asia are measured in the same units as in the US, i.e. $/MMBtu. The benchmark is the Platts JKM indicator, which is calculated using spot prices. On the CME exchange, you can find the corresponding futures with the ticker JKM.
