If the Ukrainian side loses its battle with Gazprom, it will be forced to pay multi-billion liabilities, which could potentially end up in Naftogaz going bankrupt and destabilising the gas sector in Ukraine. Depending on the scale of the Ukrainian company's failure, PGNiG could become a key supplier of gas to the Dnieper territory and Gaz-System could become a shareholder in gas infrastructure management companies in Ukraine. If Ukraine's stability of supply were to be called into question, Gazprom would gain an argument for Nord Stream 2, which, according to its declaration, would replace the Ukrainian route in its supplies to Europe by the end of 2019.
