According to yesterday's FT, Ukraine has enough gas in storage to see it through the winter but if the dispute continues Ukraine may then have to take some of the gas "allocated" by Gazprom for other European nations.
Will European nations start storing gas (can they as we are in Early January?).
If they need to but can't then price will surely rise on short term deliveries the price will bid up for LNG deliveries with knock on effects on GOM?
