The integration of bitcoin into the reserves of central banks deeply divides economic actors. On one side, some governors advocate for a diversification of assets to adapt monetary strategies to a changing world. On the other, the European Central Bank (ECB) takes a firm stance and categorically rejects any legitimacy of bitcoin as a store of value. This debate has taken on a new dimension following Christine Lagarde's statements. When asked at a press conference, the ECB president abruptly dismissed speculation, asserting that bitcoin did not meet any of the required criteria to be included in the central banks' reserves: "liquid, safe, and secure." This stance contrasts with that of the governor of the Czech National Bank, Aleš Michl, who is open to the idea of exploring new asset classes. This growing divergence illustrates the rift between a conservative approach to the financial system and a more pragmatic vision, championed by some decision-makers who seek to anticipate upcoming monetary transformations.
