Summary

Ukraine has stopped Russian natural gas transit to Europe after a prewar deal expired, citing national security concerns amid the ongoing war.

This marks a significant shift, as Russian gas continued to flow through Ukraine’s pipelines for nearly three years post-invasion.

The move aligns with Europe’s broader goal to phase out Russian gas by 2027, with Russia’s market share already plummeting to 8%.

The halt impacts countries like Moldova and highlights Europe’s diversification efforts, including U.S. and Norwegian imports.
