The Bankologist Chronicles #8 – Digital Assets: Tokenized Deposits vs Stablecoins – Two Dollars Walk Into a Bank

In my last Bankologist Chronicle, I admitted that I had spent a fair amount of time trying to understand this strange new vocabulary called Digital Assets.

Blockchain. Stablecoins. Tokenization. Wallets.

And just when I thought I had finally got my head around Stablecoins, I discovered that the rabbit hole had another rabbit hole.

Tokenized Deposits.

And that’s when two versions of the same $100 walked into a bank. One was a stablecoin and the other was a tokenized deposit. Both had the same value. They looked almost the same but they had different stories to tell.

At first glance, tokenized deposits sounded suspiciously similar to stablecoins. Both are digital. Both can represent dollars. Both can move on programmable networks. Both can potentially settle transactions in new ways.

So I asked the question that seemed almost embarrassingly simple – If I have $100 in a stablecoin and $100 in a tokenized deposit, don’t I basically have the same $100?

Apparently, in banking, asking a simple question is often the fastest way to create a 47-slide presentation. And probably a steering committee.

What Are Tokenized Deposits?

The $100 Question – Let’s forget blockchain for a moment. If I have $100 sitting in my checking account, who owes me that $100? My bank. It is a deposit. The bank owes me the money. Now imagine my bank gives me a digital representation of that same deposit that can be transferred on a programmable ledger. Nothing fundamental has changed about my relationship with the bank. I still have a deposit. The bank still owes me the money. I have simply moved from a traditional ledger to a tokenized one.

That’s essentially the idea behind a tokenized deposit. Think of it as a digital bank receipt. The bank’s ledger still says I have $100. The difference is that the bank can now create a digital token representing that same $100 deposit, which can potentially move across a programmable ledger and participate in transactions. The token is not new money. It is just a new way of representing my existing bank money.

The more I read about this, the more I realized that tokenization does not necessarily change what the money is. It can change how that money is represented, transferred and potentially programmed. So far, so good. I was feeling quite pleased with myself, and that feeling lasted about five minutes.

What Are Stablecoins?

What Are Stablecoins?Then I started looking again at stablecoins. As I explored in Chronicle #7, a stablecoin is a digital token designed to maintain a stable value against something, most commonly the U.S. dollar. Think back to my casino analogy in chronicle #7. You give the casino $100. The casino gives you 100 chips. The chips are not dollars sitting in your wallet (or your financial books). They are a representation of value that the casino promises to redeem. Now replace the casino with a stablecoin issuer and the chips with digital tokens. You have a stablecoin. The important difference is that the $100 stablecoin is not simply another format for your existing bank deposit. It is a token issued by a stablecoin issuer, backed by assets intended to support its value and redemption.

Tokenized Deposits vs Stablecoins: Who Owes You the Money?

And that brings us to the question I probably should have asked first, which is “Whose $100 is it?”

At this point, my inner banker became very interested, and my inner customer just wanted to know where his $100 went. They may both represent $100, but they represent very different financial relationships. This is where things suddenly became much clearer to me. With a tokenized deposit, my relationship is still fundamentally with my bank. With a stablecoin, my relationship is with the stablecoin issuer and the terms under which that token can be redeemed.

And there is another important difference: a tokenized deposit remains part of the bank's deposit relationship and balance sheet, while a stablecoin is issued by a separate entity with its own reserve and redemption structure. We bankers like to confuse folks by using terms like “on-book” and “off-book”, but you get it, right?

Both might say that they are worth $100, and both might sit in a digital wallet. Both might move across a blockchain. But the financial relationship underneath them is different.

And that distinction matters.

It matters for regulation, risk, liquidity and how money moves through the banking system. It even matters for the rather unglamorous question of what happens when something goes wrong, which, as every banker knows, is usually when the interesting part (and, conveniently, that's also when the lawyers start coming into the picture!).

Replace “So Why Tokenize a Deposit?” with “Why Tokenize a Bank Deposit?”

If I already have a perfectly good bank deposit, why put it on a blockchain? The answer is not necessarily “to make payments faster”. We have already spent years making payments faster. ACH is fast enough for many things. Fedwire moves large-value payments. RTP and FedNow provide instant payment capabilities. Cross-border payments are also evolving rapidly. At some point, telling me that something is going to happen “instantly” starts sounding a little like telling me my email will arrive instantly.

So what does tokenization add? Programmability.

Imagine a corporate treasury payment that does not simply say “Pay $5 million to Supplier X.”

Instead what if it says “Pay Supplier X when the shipment arrives” or “Release 20% when the invoice is approved and the remaining amount when the goods are delivered.” And the idea does not stop with trade finance. The same concept could eventually extend into everyday treasury activities such as sweeps, zero-balance accounts and automated liquidity management and investment sweeps.

Now we are talking about something more interesting than speed. We are talking about money becoming part of the business process. Some of the market research I have been reading points to exactly this possibility. Tokenized deposits could potentially make payments conditional, programmable and more closely connected to the underlying business event.

That got my attention. Because suddenly, this is not just a payments conversation. It starts looking like a corporate treasury conversation. And as someone who has spent a fair amount of time talking to treasury people, I know one thing – Give a treasurer a way to eliminate three spreadsheets, two emails and a Friday afternoon phone call, and you have their attention.

Where Do Stablecoins and Tokenized Deposits Fit?

So does that mean stablecoins don’t have a role?

Bank-Led Treasury and Liquidity Use Cases

This is where the conversation gets even more interesting. A tokenized deposit is still bank money. That makes it particularly interesting for the kinds of transactions where banks already play a central role, namely corporate payments, treasury, liquidity management and potentially trade finance.

Imagine a corporate treasury team using tokenized deposits not just to pay a supplier when a shipment arrives, but also to automate liquidity movements between accounts, execute sweeps or manage zero-balance accounts. The money is not simply moving faster. It is becoming part of the treasury process itself.

Stablecoins Across Blockchain Ecosystems

Stablecoins can potentially serve a different role. Because they are digital tokens that can circulate on blockchain networks, they can potentially move between parties without both parties maintaining the same traditional banking relationship. Tokenized deposits may be particularly interesting for bank-centric corporate and treasury use cases, while stablecoins may be particularly interesting where digitally native tokens need to move across broader blockchain ecosystems.

Another difference is where these digital dollars tend to live. Tokenized deposits would typically operate inside a bank-controlled or permissioned environment, where everyone has been invited to the party. Stablecoins, on the other hand, can travel across public blockchain networks, where the guest list is considerably more relaxed and anyone with the right wallet may be able to show up. As with most things in banking, there are exceptions. Because apparently even digital money needs footnotes.

That made me wonder whether the future is really about stablecoins versus tokenized deposits, or whether banks could end up participating in both. A bank could, for example, provide the regulated banking infrastructure and hold the underlying deposits for a separate stablecoin issuer, while that issuer provides the digital token and customer-facing experience. Suddenly, the two are not necessarily competitors. They could become two different layers of the same ecosystem.

And now my simple $100 question has somehow turned into an architecture discussion!

How the GENIUS Act Distinguishes Payment Stablecoins from Deposits

Then, just when I thought I was getting comfortable with the terminology, regulation entered the conversation. The U.S. GENIUS Act establishes a federal framework specifically for payment stablecoins. It also distinguishes payment stablecoins from traditional deposits, including deposits that may be recorded using distributed ledger technology.

In other words, simply putting a bank deposit on a blockchain does not magically turn it into a stablecoin.

So Which One Wins?

I am deliberately not going to ask that question, because I suspect that may be the wrong question. Stablecoins and tokenized deposits do not necessarily have to fight for the same job. They may coexist.

Stablecoins could play roles where digitally native, transferable tokens on blockchain networks
are useful. Tokenized deposits could bring the benefits of programmability and tokenization into
the existing banking system while preserving the familiar bank-deposit relationship.

For me, the bigger realization is that digital money is not just one thing. Just because two things look like $100 on a screen (and may even walk into the same blockchain) does not mean they have the same structure underneath. And perhaps that is the real lesson from my digital-assets journey so far.

The technology may be new. The vocabulary may be new. But underneath all of it, bankers are still asking some very familiar questions:

Who owes me the money? Who holds the risk? How does it move? Can I trust it? And what happens when something goes wrong?

I have a feeling my coffee machine is going to be working overtime for the next Chronicle.
