Shocked: Electricity Price Volatility Spillovers in Europe
Serhan Cevik
and
Yueshu Zhao
European electricity markets are in the midst of unprecedented changes—caused by Russia’s invasion of Ukraine and the rise of renewable sources of energy. Using high-frequency data, this paper investigates volatility spillovers across 24 countries in the European Union (EU) during the period 2014–2024 to provide a better understanding of the transmission of risks in an international context. We develop both a static and a dynamic assessment of spillover effects and directional decomposition between individual countries. Our main findings show that about 73 percent of the forecast error variation is explained by cross-variance shares, which means only 27 percent can be attributed to shocks within each country. In other words, cross-border volatility spillovers dominate the behavior in national electricity markets in Europe—and this effect has grown over time. We also implement an augmented gravity model of bilateral volatility spillovers across power markets in the EU. Altogether, these results provide important insights to policymakers and regulators with regards to greater integration of electricity markets and infrastructure improvements that would also help with the transition to low-carbon sources of power generation and strengthen energy security in Europe.

Energy Transition and Geoeconomic Fragmentation: Implications for Climate Scenario Design

The transition to a low-carbon economy, which is needed to mitigate climate change and meet the Paris Agreement temperature goals, has been affected by the supply chain and energy supply disruptions that originated during the COVID-19 pandemic, the Russian invasion of Ukraine, and the subsequent energy crisis and exacerbation of geopolitical tensions. These developments, and the broader context of the ongoing “polycrisis,” can affect future decarbonization scenarios. This reflects three main factors: (1) pullbacks in climate mitigation policies and increased carbon lock-in in fossil fuel infrastructure and policymaking; (2) the decreasing likelihood of continuous cost reduction in renewable energy technologies; and (3) the likely intensification of macroeconomic shocks amid increasing geoeconomic fragmentation, and the associated policy responses. In this context, the note assesses the implications of the polycrisis for hypothetical scenarios used to assess climate-related financial risks. Following an analysis of the channels through which these effects are likely to materialize over short- and long-term horizons and some policy implications, the note proposes potential adjustments to the design of the climate scenarios used by financial institutions, central banks, and financial sector supervisors and regulators within their risk management frameworks.

Chasing the Sun and Catching the Wind: Energy Transition and Electricity Prices in Europe
Mr. Serhan Cevik
and
Keitaro Ninomiya
European power markets are in the midst of unprecedented changes, with a record-breaking surge in energy prices.This paper investigates the impact of green power resources on the level and volatility of wholesale electricity prices at a granular level, using monthly observations for a panel of 24 European countries over the period 2014–2021 and alternative estimation methods including a panel quantile regression approach. We find that renewable energy is associated with a significant reduction in wholesale electricity prices in Europe, with an average impact of 0.6 percent for each 1 percentage points increase in renewable share. We also find evidence for a nonlinear effect—that is, higher the share of renewables, the greater its effect on electricity prices. On the other hand, while quantile estimation results are mixed with regards to the impact of renewables on the volatility of electricity prices, we obtain evidence that renewable energy has a negative effect on volatility at the highest quantiles. Overall, our analysis indicates that policy reforms can help accelerate the green transition while minimizing the volatility in electricity prices.

Payment Arrears in the Gas and Electric Power Sectors of the Russian Federation and Ukraine
Emine Gürgen
and
Hrant Bagratian
This paper discusses payments arrears in the Russian Federation and Ukraine, with emphasis on the gas and electric power sectors. Payments arrears, which were triggered primarily by the dislocations experienced during the transition from a centrally planned to a market economy, have reached significant proportions in these two countries. Governments have aggravated the problem by not honoring their own bills and by condoning payments arrears outside the budget. The paper argues that the solution to the problem lies in the implementation of comprehensive systemic reforms and outlines possible measures.
