Gas
Sustained gas for power demand throughout January as unchanged fundamentals kept the market tight. This winter premium is expected to continue into February as low temperatures are forecast across the UK and NW Europe, enhancing supply concerns. Gas markets continue to lift to compete with Asian markets for LNG cargoes. This effort to replenish storage will be a significant task, as levels sit at 27% in the UK. S25 contract continues to trade at a premium to W25, to sustain high LNG cargo imports. Twelve LNG cargoes expected over the next two weeks.
Looking ahead
Volatility is expected to continue across markets in February, as European weather, storage levels and geopolitical headlines drive demand upwards, with long term forecasts more uncertain. The outcome of tensions between Russia and Ukraine could impact prices. Further sanctions are imposed on Russia from the US and talks to restart gas transit through Ukraine are ongoing. Trump’s “Drill, baby, drill” sentiment suggests more US LNG supply to Europe, while US trade tariffs could also change global demand forecasts in the coming months.
