Forecasts are turning colder across the Northern Hemisphere, and utilities ETFs may deserve a closer look as a potential seasonal trade. Weather experts caution that a weakening polar vortex could allow Arctic air to sweep into the U.S., Europe and Asia this winter in a shift that could hike heating demand and push electricity prices higher, putting fresh pressure on already-strained grids.
In the U.S., where wholesale power costs have already risen due to the surge in energy-hungry data centers and AI infrastructure, even a short cold spell could squeeze supplies further. According to forecasters, the Midwest and Northeast are most at risk. Utilities are poised to see demand spikes as both households and industries scramble to keep operations running amid freezing temperatures.
