Czech National Bank is studying bitcoin. That is not the same as adopting it.
The CNB's $1M digital-asset test portfolio is due diligence, not a reserve commitment. There's a difference, and it matters for how you read every central bank's next move.

- →Czech National Bank Governor Aleš Michl said at Bitcoin 2026 that bitcoin could improve reserve returns but could also go to zero, while the CNB runs a $1 million digital-asset test portfolio.
- →The test portfolio signals institutional due diligence, not adoption: the Bank Board already voted against putting FX reserves into bitcoin, and the $1M position covers less than 0.001% of CNB assets.
- →Watch the CNB's formal assessment, due within two to three years: a board recommendation for any bitcoin FX reserve allocation would be the first of its kind from an EU central bank.
- tokenized deposit → A traditional bank deposit represented as a token on a blockchain, letting it move and settle like crypto while staying backed by a real bank account.
- foreign-exchange reserves → The pool of foreign currencies and assets a central bank holds to stabilize its own currency and cover international payments.
Around 0.0006% of the Czech National Bank's balance sheet is now sitting in bitcoin, a USD stablecoin, and a tokenized deposit, per the bank's own blog. The test portfolio totals $1 million, per a CNB press release. This is not the start of a reserve program. It's closer to what central banks do when they're trying to understand an instrument before committing real reserves to it.
Governor Aleš Michl said at the Bitcoin 2026 conference in Las Vegas, per CoinDesk, that bitcoin could improve reserve portfolio performance but could also theoretically go to zero. The CNB's Bank Board had already voted against putting foreign-exchange reserves into bitcoin. The $1M test and the no-reserves vote are consistent: the institution is building operational literacy, not a position.
The closest parallel is how central banks approached inflation-linked bonds in the late 1980s and 1990s. Novel instrument, unfamiliar risk profile, small informational positions for years before a formal reserve recommendation. The CNB's own research note says bitcoin's short history and unstable financial characteristics limit confidence in historical portfolio findings. That's not a rejection; it's a prerequisites list.
Foreign-exchange reserves make up about 98% of the CNB's total assets, per the bank's research. The assessment window for the test portfolio runs two to three years, per CNB. Any eventual allocation recommendation would have to survive another Bank Board vote, and that board already said no once. What the test buys is operational data: custody mechanics, settlement risk, counterparty exposure. The kind of evidence that turns "theoretically interesting" into "board-ready."
Michl's "could go to zero" remark is accurate and will circulate as bearish. It shouldn't be read that way. A central banker who names downside risk explicitly is not ruling the asset out; they're describing the evidence threshold for saying yes.
The move the CNB hasn't made is sharing its test methodology with the ECB and the BIS; an experiment that stays inside one institution isn't building the knowledge base bitcoin needs to earn central-bank trust at scale.
The CNB's formal assessment from the test portfolio: if it produces a recommendation for any FX reserve allocation to bitcoin before mid-2028, that's the signal every other EU central bank will need to start their own review.
