The statement attributes to the Governor of the European Central Bank, Christine Lagarde, a call for preparedness for rapid changes in interest rates due to an increase in energy prices. This assertion is strongly supported by direct and authoritative evidence from official ECB communications. The official interview published on the ECB’s website contains remarks by Lagarde discussing the macroeconomic impacts of rising energy prices and the potential for corresponding interest rate adjustments, explicitly linking the two. An official address before the European Parliament’s Committee on Economic and Monetary Affairs further supports this link, in which Lagarde highlighted the importance of maintaining agility in monetary policy in response to volatile energy-driven inflation dynamics. Both sources are primary and official ECB publications, ensuring high credibility and direct relevance. Additional ECB research and working materials corroborate the thematic focus on preparedness and policy flexibility but do not add contradicting information. No authoritative evidence was found disputing or rejecting the idea that the ECB Governor emphasized readiness for swift interest rate action in light of energy price shocks. Hence, based on the convergence of multiple high-authority and high-relevance sources, the statement is very likely true.
