Tokenized Real-World Assets: Bonds, Funds and Buildings on a Ledger

Most of the crypto debate revolves around assets that exist only on a blockchain. Tokenization turns that logic around. It takes something that already exists in the traditional financial world, such as a government bond, a unit in a money market fund or a commercial building, and records its ownership as a digital token on a distributed ledger.

The idea has moved from conference slides into real transactions. In recent years, development banks, some public issuers and large companies have placed bonds directly on blockchain platforms. Several large asset managers have launched tokenized money market funds, and central banks, including the European Central Bank, have run trials on how such transactions could be settled in central bank money.

None of this means that the financial system is about to move onto blockchains. It means that institutions which usually adopt new technology slowly see enough potential to experiment. Understanding why requires a closer look at what a token actually changes, and what it leaves untouched.

What tokenization actually means

A token is an entry on a shared ledger that records who holds what and allows that holding to be transferred. In a tokenized bond, the token represents the bond itself or a claim to it. In a tokenized fund, it represents a fund unit. For real estate, the token usually represents a share in a company that owns the building, not the building directly.

Two models are common. In the first, the asset is native to the ledger: the security is issued as a token from the start, and the ledger serves as the official register. In the second, the token is a digital twin: the asset sits with a custodian in the traditional system, and the token mirrors it. The second model is easier to set up but adds a layer of trust, because someone has to keep both records in line.

Why banks and asset managers experiment

The motivation is mostly operational. Securities trading today involves a chain of intermediaries, including trading venues, central counterparties, central securities depositories and custodian banks, each with its own records. Many markets settle one or two business days after a trade, and reconciling all those records costs time and money.

Supporters point to several potential improvements. Most of them are still being tested:

• Faster settlement: transfers can be completed within minutes, and in some designs, the delivery of the asset and the payment happen in a single step.
• Longer operating hours: ledgers can run around the clock, unlike most traditional market infrastructure.
• Programmable features: interest payments, redemptions or transfer restrictions can be built into the token itself.
• Smaller units: assets can be divided into fractions, which in theory opens them to a wider group of investors.
• Mobile collateral: tokenized bonds or fund units could be moved quickly between parties to secure other transactions.

Tokenized money market funds have attracted particular interest. They offer a way to hold a low-risk, interest-bearing asset directly on a blockchain. That is useful for firms that already operate there and want an alternative to stablecoins, which generally pay no interest to their holders.

Fractional ownership: promise and reality

The idea of buying a small slice of an office tower or a vineyard has made tokenization popular well beyond professional markets. In principle, tokens make it technically simple to divide an asset into thousands of units and to keep track of many small holders.

In practice, the barriers are rarely technical. Securities law, prospectus requirements, investor protection rules and tax treatment apply regardless of whether a share is recorded on paper or on a ledger. A tokenized building also remains a building: it needs maintenance, tenants and a valuation, and its value does not become more stable because ownership is recorded digitally.

Smaller units can also create a misleading impression of liquidity. Being able to buy a fraction of an asset is not the same as being able to sell it quickly at a fair price.

The legal layer: who owns what

The most important question in tokenization is not technical but legal. A token on a ledger is only valuable if a court would recognize it as a claim to the underlying asset. If the token and the legal title drift apart, the legal title wins. Anyone holding a token needs to know what exactly it represents, who stands behind it and what happens if an intermediary fails.

Germany offers a concrete example. The Electronic Securities Act, known by its German abbreviation eWpG and in force since June 2021, allows securities to be issued without a paper certificate. They can be entered either in a central register kept by a central securities depository or a custodian, or in a crypto securities register maintained on a tamper-resistant recording system such as a distributed ledger. Whoever keeps such a register needs an authorization from BaFin, the federal financial supervisor.

Under the law, an electronic security is treated as a movable thing, which allows established rules on ownership and transfer to apply. The scope started with bearer bonds and has since been widened in steps, for example to fund units. Real estate shows the limits of such approaches: in Germany, the land register remains the authoritative record of who owns a property, and no token can replace it.

A token is only as good as the legal promise behind it.

At the EU level, tokenized securities that qualify as financial instruments fall under existing securities law rather than under MiCA, the crypto rulebook. Since March 2023, an EU pilot regime has also allowed market infrastructures to test trading and settlement on distributed ledgers under adapted rules.

Limits and open questions

For all the activity, tokenized markets remain small compared with traditional ones, and several problems are unresolved. Four stand out.

Liquidity is the first. Many tokenized assets trade rarely after issuance, if at all. Without active secondary markets, the theoretical advantage of instant transfers matters little.

Interoperability is the second. Tokens are issued on a range of public and private ledgers that often cannot communicate with each other or with existing systems. Bridges between ledgers have repeatedly been targets of large attacks in the crypto sector, which makes institutions cautious.

The third is the cash leg. Settling a tokenized bond in seconds only helps if the payment can move on the ledger as well. Options include stablecoins, tokenized bank deposits and settlement in central bank money, and each raises its own regulatory and practical questions.

Finally, there are operational risks. Smart contracts, the programs that execute automatically on a ledger, can contain errors, keys can be lost, and it is still debated how much transaction data should be visible on public networks.

A gradual change in infrastructure

Tokenization looks less like a sudden break than like a slow replacement of back-office processes. It is gaining ground where the benefits are clearest: money market funds, short-term bonds and collateral management between professional parties. Whether it spreads further depends on legal certainty, on reliable on-chain money and on whether different ledgers can be connected safely.

For private investors, the most important point is a sober one. A tokenized product is still the product it represents, with the same economic risks, plus some technical and legal ones of its own. Before anything else, it is worth understanding what the token actually entitles its holder to, and under which law.
