Why Tokenized Assets Still Need Traditional Cash to Settle

Tokenization promises to move stocks, bonds, funds and other financial assets onto blockchain networks.

But putting an asset onchain solves only half of a trade.

When an investor buys $10,000 of a tokenized Treasury, the seller must deliver the security while the buyer must deliver $10,000 in money. Both sides still need to settle.

That creates one of the most important questions in tokenized finance: what money will actually pay for tokenized assets?

Tokenizing the Asset Is Only Half the Transaction

Traditional financial markets already solve this problem through a process known as delivery versus payment, or DvP.

The basic principle is simple. The buyer delivers cash while the seller delivers the security.

Banks, custodians, clearinghouses and settlement systems coordinate those movements so one party does not hand over its asset without receiving payment.

Blockchain technology could make that process faster.

Instead of securities and cash moving through several institutions, a tokenized system could exchange both simultaneously.

This is known as atomic settlement.

Imagine Alice buys a tokenized bond from Bob. The system locks Alice's digital money and Bob's bond token, verifies that both are available, and completes both transfers at the same time.

If either side cannot deliver, neither transfer happens.

Atomic settlement could reduce counterparty risk and shorten the time capital remains tied up between trade execution and final settlement.

But it works properly only if reliable money can move on the same digital infrastructure as the asset.

That is where the challenge begins.

Stablecoins, Bank Deposits or Central Bank Money?

There are three major candidates for the cash side of tokenized markets: stablecoins, tokenized bank deposits and tokenized central-bank money.

Stablecoins are already widely available on public blockchains.

A tokenized Treasury could therefore be exchanged for a dollar-backed stablecoin without either party leaving the blockchain.

That makes stablecoins attractive for 24/7 markets.

However, a stablecoin is normally a liability of a private issuer. Its value depends on the quality of its reserves and the issuer's ability to redeem tokens for conventional money.

That is different from holding money directly at a bank or central bank.

Tokenized bank deposits offer another possibility.

These represent existing commercial-bank deposits in token form. Instead of creating a separate stablecoin, a bank could allow its customers to transfer deposit money through programmable digital infrastructure.

The important difference is legal.

A tokenized deposit remains a liability of the bank, similar to money already sitting in a conventional bank account.

Commercial banks are increasingly interested in this model because it could allow programmable settlement without completely rebuilding the existing banking system.

The third option is tokenized central-bank money.

For large financial institutions, this could be especially important because central-bank reserves already sit at the top of the traditional settlement system.

Banks can fail. Stablecoin issuers can experience redemption pressure. Central-bank money does not depend on the solvency of a private company.

Why Wall Street Still Needs the Cash Leg

The problem becomes more important as tokenization expands beyond experiments.

A blockchain may be capable of transferring a tokenized stock almost instantly. But if the payment still needs to pass through conventional banking systems, the transaction is not fully onchain.

Recent institutional projects illustrate this hybrid structure.

Banks and financial companies are experimenting with tokenized Treasuries, deposits and funds while still relying on established banking infrastructure for some parts of settlement.

That is not necessarily a weakness.

Financial markets are unlikely to move from traditional settlement to fully tokenized infrastructure overnight.

Instead, the two systems may coexist for years.

A tokenized security could trade on blockchain while its payment moves through a commercial bank. Another transaction might use a stablecoin. Large institutions could eventually settle using tokenized central-bank reserves.

The important question is whether these different forms of money can interact safely.

Interoperability may therefore matter as much as tokenization itself.

A market containing thousands of tokenized securities provides limited improvement if each asset requires a different payment network or cannot connect with the banking system.

This is why the future of tokenized finance is not simply about putting more assets on blockchain.

It is about connecting assets and money.

Tokenized stocks and bonds may eventually trade around the clock and settle almost instantly. But every purchase will still require something trustworthy on the other side of the transaction.

The real breakthrough comes when the security and the cash can move together.

Until then, tokenization has solved only half the trade.
