Abstract
This study employs synthetic control methods to estimate the effect of the Iberian exception mechanism on wholesale electricity prices and consumer inflation, for both Spain and Portugal. We find that the intervention led to an average reduction of approximately 40% in the spot price of electricity between July 2022 and June 2023 in both Spain and Portugal. Regarding overall inflation, we observe notable differences between the two countries. In Spain, the intervention has an immediate effect, and results in an average decrease of 3.5 percentage points over the twelve months under consideration. In Portugal, however, the impact is small and generally close to zero. Different electricity market structures in each country are a plausible explanation.

Carbon Transition Risk and Corporate Loan Securitization
Isabella Müller, Huyen Nguyen, Trang Nguyen
IWH Discussion Papers,
No. 22,
2022
Abstract
We examine how banks manage carbon transition risk by selling loans given to polluting borrowers to less regulated shadow banks in securitization markets. Exploiting the election of Donald Trump as an exogenous shock that reduces carbon risk, we find that banks’ securitization decisions are sensitive to borrowers’ carbon footprints. Banks are more likely to securitize brown loans when carbon risk is high but swiftly change to keep these loans on their balance sheets when carbon risk is reduced after Trump’s election. Importantly, securitization enables banks to offer lower interest rates to polluting borrowers but does not affect the supply of green loans. Our findings are more pronounced among domestic banks and banks that do not display green lending preferences. We discuss how securitization can weaken the effectiveness of bank climate policies through reducing banks’ incentives to price carbon risk.

Climate Change-Related Regulatory Risks and Bank Lending
Isabella Müller, Eleonora Sfrappini
ECB Working Paper,
No. 2670,
2022
Abstract
We identify the effect of climate change-related regulatory risks on credit real-location. Our evidence suggests that effects depend borrower's region. Following an increase in salience of regulatory risks, banks reallocate credit to US firms that could be negatively impacted by regulatory interventions. Conversely, in Europe, banks lend more to firms that could benefit from environmental regulation. The effect is moderated by banks' own loan portfolio composition. Banks with a portfolio tilted towards firms that could be negatively a affected by environmental policies increasingly support these firms. Overall, our results indicate that financial implications of regulation associated with climate change appear to be the main drivers of banks' behavior.

Inside Asset Purchase Programs: The Effects of Unconventional Policy on Banking Competition
Michael Koetter, Natalia Podlich, Michael Wedow
ECB Working Paper Series,
No. 2017,
2017
Abstract
We test if unconventional monetary policy instruments influence the competitive conduct of banks. Between q2:2010 and q1:2012, the ECB absorbed Euro 218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Using detailed security holdings data at the bank level, we show that banks exposed to this unexpected (loose) policy shock mildly gained local loan and deposit market shares. Shifts in market shares are driven by banks that increased SMP security holdings during the lifetime of the program and that hold the largest relative SMP portfolio shares. Holding other securities from periphery countries that were not part of the SMP amplifies the positive market share responses. Monopolistic rents approximated by Lerner indices are lower for SMP banks, suggesting a role of the SMP to re-distribute market power differentially, but not necessarily banking profits.

Liberalization of Electricity Markets in Selected European Countries
Albrecht Kauffmann, M. Keim, P. J. J. Welfens
Diskussionsbeiträge des Europäischen Instituts für Internationale Wirtschaftsbeziehungen (EIIW), Bergische Universität Wuppertal, Nr. 124,

Abstract
Der Beitrag beschäftigt sich mit Fragen der Liberalisierung der Elektrizitätsmärkte in der EU. Man kann feststellen, dass die Gemeinschaftsdirektive 96/92/EC die Wechselbeziehungen der Elektrizitätsmärkte nicht ausreichend behandelt. Außerdem wird vor allem in Deutschland der Zugang für Dritte nicht effektiv gefördert, wobei der Zusammenschluss eines großen Elektrizitätsunternehmens und einem dominanten Gasunternehmen neue spezielle Fragen aufgeworfen hat. Hingegen verläuft der Liberalisierungsprozess in Skandinavien konsequenter. Osteuropäische EU-Beitrittsländer sind langfristig potenzielle Elektrizitätsexporteure sobald Modernisierungen zu niedrigeren Energie- und Elektrizitätsverbrauch führen. Russland sollte rasch WTO-Mitglied werden, um Zugang zu den westeuropäischen Elektrizitätsmärkten zu bekommen, wobei Russland in den gesamten Liberalisierungsdiskussionen noch keine Rolle gespielt hat. Mittelfristig können Überschusskapazitäten in einer EU-27 erwartet werden. Zweifelhaft jedoch ist, ob Politiker, die ansonsten so ehrgeizige Ambitionen in der Umweltpolitik zeigen, einer gesamteuropäischen Liberalisierung der Elektrizitätsmärkte zustimmen werden. Außerdem werden regulierungspolitische Aspekte behandelt.
