Independently green? An integrated strategy for a transformative ECB

What should be the role of the ECB in tackling the socio-ecological challenges related to planetary boundaries, such as climate change and loss of biodiversity? A clear answer to this question is still lacking, in spite of the strategy review of 2021. Regretfully, this review has not received the scrutiny it deserves, as the pandemic and the war in Ukraine have taken center stage. Taking these recent developments into account, we provide a critique of the new strategy. We argue that it lacks transformativity, as it subsumes climate change under the policy objective of price stability, assumes that transformations can be mastered within the structures of the past, and refrains from questioning the current institutional set up. In its main part, the paper discusses the historical relevance of what we believe is the main reason for these deficits: The fear that taking up the real issues (such as independence and accountability) would make the ECB a political football in times of rising inflation. Taking these fears seriously, we show that the institutionalization of central banking has always reflected the transformative dynamics of their time. Consequently, if planetary boundaries represent a transformative challenge, they will radically change the ECB, too. Moreover, we provide evidence that central banks' historical transformations have always reflected their peculiar position as mediators between the financial and the political realm. We argue that, at the current juncture, transforming central banking implies moving away from finance and towards politics. This involves risks. However, we argue that the historical experience offers few reasons to fear a closer integration of central banking into the public sphere, as long as the latter is dominated by democratic politics. Consequently, if one comes to the conclusion that the ECB's current corset is too narrow, it can and should be augmented. While we do not offer a blueprint for such augmentation, we conclude our analysis by sketching elements of a sustainable strategy for a transformative ECB.
