Governments rapidly provided large support to help households and firms face the 2021-22 energy price crisis. Drawing on the OECD Energy Support Measures Tracker and country case studies, this paper documents countries’ policy responses and draws lessons for enhancing countries’ preparedness to future energy price shocks. Support implemented or announced by countries so far has been largely untargeted and often fiscally costly. As such it might add to inflationary pressures and in many cases reduce incentives to save energy and transition away from fossil fuels. Reliance on imported energy, technical obstacles to implement a targeted approach and political economy constraints help explain the type of support countries provided. There is now a case for withdrawing broad-based energy support, given the recent moderation in energy prices and ongoing or planned minimum-wage and welfare-benefit increases to compensate for high inflation. Digitalisation would help improve the quality of support countries can provide to face a future energy or other crisis by speeding up payment delivery and facilitating a more targeted approach based on vulnerability factors beyond low income, such as the inability to renovate an energy-inefficient home. Ensuring that support measures maintain incentives for energy savings and encourage energy diversification, combined with investments to accelerate the green transition, is key to reducing vulnerability to energy price shocks.
