This paper first shows that, contrary to conventional wisdom, the European Central Bank (ECB) can influence global energy prices. Second, through Lucas critique-robust counterfactual analysis, we uncover that the ECB’s ability to affect fast-moving energy prices plays an important role in the transmission of monetary policy. Third, we empirically document that, to optimally fulfill its primary mandate, the ECB should swiftly tighten policy in response to an increase in energy prices. Crucially, the tightening required depends on the ECB’s ability to influence global energy prices.
