Czech central bank opened a reserve review after Bitcoin proposal

The Czech National Bank’s board approved an analysis of additional reserve asset classes on January 30, 2025, after Governor Aleš Michl proposed examining bitcoin through a test portfolio.

The decision did not add bitcoin to the bank’s international reserves, authorize a purchase or commit the institution to a future allocation. It nevertheless moved the subject from a governor’s public proposal into the central bank’s formal analytical process—a notable institutional step while monetary authorities generally treated bitcoin’s volatility, custody demands and financial-crime exposure as incompatible with reserve management.

The development immediately exposed a divide inside European central banking. At a January 30 European Central Bank press conference, President Christine Lagarde said she was confident bitcoin would not enter the reserves of any central bank represented on the ECB’s General Council.

What the Czech board approved

The Czech National Bank’s announcement said its board had reviewed international reserve management for 2024 and approved a proposal to analyze investment in additional asset classes. The institution had been diversifying its portfolio over the preceding two years and would assess whether other assets could improve diversification and returns.

The official release deliberately described the mandate broadly and did not say that bitcoin had been approved as a reserve asset. A separate record published by the bank under Michl’s name identified his January 30 proposal more specifically: he had asked for analysis of a possible bitcoin test portfolio.

That distinction defines the verified event. The board authorized research into an expanded investment universe; it did not approve bitcoin ownership. The bank said no portfolio changes would occur until the analysis was completed and the board decided how to proceed. Any eventual reserve changes would be reported through its quarterly reserve information and annual report.

Michl characterized bitcoin as a highly risky alternative asset whose possible outcomes included extreme gains or a collapse toward zero. His case for studying it rested on institutional learning and reserve diversification, not on a claim that bitcoin had already satisfied the conventional requirements for sovereign reserves.

Lagarde drew the opposing line

Asked about the Czech proposal on January 30, Lagarde said reserves needed to be liquid, secure and safe, and should not be burdened by suspicions of money laundering or other criminal activity. She said she had discussed the matter with Michl and expressed confidence that bitcoin would not enter the reserves of the General Council’s central banks.

The Czech Republic was an European Union member but did not use the euro. Its central bank therefore participated in the ECB’s General Council while retaining responsibility for the Czech koruna and its own reserve portfolio. Lagarde’s statement represented a powerful institutional objection, but it was not a legal order preventing the Czech bank from conducting an analysis.

The exchange clarified the stakes. Reserve assets serve policy and crisis-management functions that require dependable liquidity, operational control and predictable legal treatment. Bitcoin offered a potential diversification argument, but its price volatility, bearer-asset custody model and fragmented global market raised risks unlike those attached to conventional government securities or bank deposits.

What remained unresolved on January 30

The Czech National Bank did not publish a target allocation, acquisition timetable, custody plan, legal opinion or risk budget on January 30. It also did not disclose when the analysis would be completed. Contemporaneous reports that discussed a possible multibillion-euro allocation described Michl’s proposal, not an approved investment.

No market-return claim is warranted from the surviving records. Bitcoin trades continuously across venues, and neither the Czech announcement nor the ECB press conference supplied a defined instrument, exchange, benchmark or event-time price window from which to measure a reaction.

The defensible January 30 conclusion is consequently narrow but significant: a European Union central bank formally agreed to study a broader reserve universe after its governor placed bitcoin on the agenda. Whether that research would produce an actual reserve holding remained entirely open.
