Bitcoin-Holding Central Bank Tokenizes Bond, Shuns Stablecoins

In a November 10 press release, the CNB said it had issued koruna bonds in tokenized form on the distributed-ledger platform of the Central Securities Depository and used it for transfers, purchases and sales against payment, and repo transactions during October and November.

Governor Aleš Michl supplied the numbers in a speech at the CzechCrunch Money Maker conference in Prague. The counterparty was Česká spořitelna. Each bond carried a nominal value of CZK 10,000, roughly €400, and the whole programme moved tens of thousands of koruna. That is a handful of bonds and a total in the low thousands of euros.

What the pilot covered

The instruments were the CNB’s own short-dated paper, the kind it uses in monetary-policy operations, and the bank says the tests confirmed the infrastructure can serve both those operations and its reserve management. Interest payments were part of the run, alongside the purchases, sales and repos.

The network is closed. Only approved financial institutions can join, each transaction record is visible solely to its counterparties, and in Michl’s words there are “no miners.” Settlement completed almost instantly, and the platform can in principle operate around the clock.

The CNB describes the exercise as end-to-end: contracts, rules and internal processes were rewritten before a single token moved. In parallel, it bought a euro-denominated government bond that exists only on a distributed ledger, as part of its reserve-management testing.

Shelves and checkouts

Michl framed the project with a shop metaphor. A currency has shelves, meaning the securities denominated in it, and checkouts, meaning how fast and reliably you can pay. The dollar wins on shelves. A small currency, he argued, can grow its market by having better checkouts, citing a model from this year’s Jackson Hole symposium in which the two factors multiply rather than add, so a zero on either side gives zero overall.

Instant payments were the first checkout upgrade. The tokenized bond is pitched as the next one, and the stated goal is “a large market for koruna-denominated assets that are easier to buy and sell than German Bunds.”

Then came the condition that gives the announcement its edge: “The central bank must be involved from the outset, so that settlement has central bank money at its core, not private money such as stablecoins.”

A tokenized bond is a shelf. The checkout is whatever money changes hands when Česká spořitelna buys it. On that point, neither the release nor the speech says what was used.

The money behind the bond

When a bank buys a security, delivery and payment have to land together so that neither side hands over its leg without receiving the other. Putting the bond on a ledger settles the delivery half. The payment half depends on what kind of claim the seller ends up holding.

Michl’s preference is the orthodox one. The CPMI-IOSCO principles for market infrastructures already steer settlement towards central-bank money wherever that is practical, and demand tight control of credit and liquidity risk where commercial-bank money is used instead.

The CNB owns the obvious tool for the job. It runs CERTIS, the koruna’s interbank payment system, which already handles the instant payments Michl cited as the previous step. What the documents leave open is whether the pilot’s cash leg moved there, on the depository’s own ledger, or through some tokenized balance built for the test. Coindoo has looked at how other tokenized bonds have handled the cash side; the Czech answer is not yet on the record.

Why Prague cannot borrow Frankfurt’s checkout

Eurozone issuers are getting their central-bank cash leg built for them. The ECB’s Pontes service, launched on September 21, links tokenized wholesale markets to euro central-bank money, with longer hours and added functions to follow. Coindoo covered the design of that bridge at launch.

The Czech Republic is not in the euro area, so Pontes settles nothing in koruna. That turns Michl’s line about stablecoins from a general principle into a specific obligation: if koruna bonds are to settle in central-bank money, the CNB has to provide that money on-ledger itself. The speech title, “the new physics of the digital koruna,” points that way, and the reference list behind it includes Darrell Duffie’s Jackson Hole paper on tokenized finance and the perimeter of central banking. The release itself describes a test, not a decision.

The repo was the harder test

A transfer shows a token can move. A repo shows it can be borrowed against. Michl described the test plainly as lending with the DLT bond as collateral, which is how banks finance holdings they do not want to sell.

Two things make this an easier case than it will be elsewhere. The collateral is CNB paper, which the Czech banking system already accepts without debate, and the lender in a central-bank repo sets its own terms. In a market between commercial banks, the lender still has to decide eligibility, haircut and tenor, and no ledger makes those calls. The pilot showed the mechanics work for a counterparty of one; it did not show that koruna tokens have a funding market.

Where bitcoin fits

A year earlier, the CNB built a test portfolio of bitcoin, a dollar stablecoin and a tokenized deposit, held outside its reserves to learn how such assets behave legally, operationally and in the accounts. Two of those three are exactly the payment assets it is now declining to put at the centre of settlement. The portfolio was a study of the alternatives; the bond is a vote against them, at least for the wholesale cash leg.

Michl’s description of the technology makes the same cut. The platform “takes what is useful from bitcoin and discards what regulated finance cannot use.” His end state is explicit: an AI agent that manages a person’s digital koruna, collects the salary, shifts savings between banks overnight for a few basis points, and never waits for opening hours. He put the share of koruna transactions that could one day be machine-to-machine at 95 per cent.

That vision needs a checkout that is open at 3 a.m. and settles in money nobody can default on. The bond proves the shelf. Michl himself called the first issue “a number, not a zero.” The digit still missing is the one describing what paid for it, and the next meaningful disclosure from Prague is the one that fills it in.
