Stablecoin enthusiasts believe the U.S. market is ripe for widespread adoption, with businesses and consumers prepared to accept the fully reserved nature of stablecoins as an alternative to traditional FDIC-insured deposits.

Key insight: Stablecoins do indeed promise greater payments efficiency. However, I believe deposit insurance will continue to matter even if use of stablecoins becomes widespread in the U.S. — and an interoperable system for tokenized deposits could provide the best of both worlds for businesses and consumers.

Need to Know:

FDIC insurance originated in the need to maintain confidence in fractional reserve banking, so it rightly does not apply to fully-reserved assets.
In practice, new regulatory regimes can’t (and aren’t intended to) provide real-time certainty or reserves or the prompt payout of claims in the event of an issuer bankruptcy.
This will matter to enough U.S. consumers and businesses to make stablecoins more likely to supplement than replace traditional deposits.
U.S. banks have an opportunity to use tokenized deposits to blend the best features of traditional deposits with the payment efficiency of stablecoins.
However, this will require strong coordination across the industry to create interoperable solutions. Banks’ loss of market share in P2P payments to more nimble fintech competitors highlights that this is not a given.

Why FDIC Insurance Will Continue to Matter

There are good reasons why many businesses and consumers will continue to value FDIC insurance, even with new regulations covering regulated stablecoins.

The argument some have made that FDIC insurance no longer matters in a world where GENIUS-compliant stablecoins are backed one-to-one with cash equivalents is really simple: If every dollar is sitting there fully reserved, why do you even need insurance?

There’s some logic to that. A fully reserved asset is structurally different from fractional reserve banking, where most of your deposit is out the door, getting loaned to someone else the moment it lands.

Here’s where I’d push back.

FDIC insurance doesn’t just protect us from classical bank runs and credit quality problems. It’s also protecting us from fraud, operational mistakes, or other “oops” moments.

Key difference: If a bank has a major oops moment, the FDIC steps in. If a stablecoin issuer has one, it likely won’t.

At a macro level, there’s a strong public policy case for this distinction. We’ve historically believed that bank deposits matter because they allow for fractional reserve lending. The whole reason we have FDIC insurance is to allow fractional-reserve lending to power the economy while preventing destabilizing bank runs.

These arguments don’t apply to stablecoins.

Stablecoins don’t power fractional reserve lending (at least, not directly). And if there is a run on a well-managed stablecoin, the issuer will simply sell some of the high-quality assets that back it and redeem the stablecoin. No need for the FDIC backstop to prevent the destabilizing impact of a solvent bank failing through a liquidity crisis.

It is true that the Office of the Comptroller of the Currency will regulate stablecoin issuers under the GENIUS Act, but that isn’t a substitute for the protections of FDIC insurance. The OCC would be the first to say that its oversight can’t possibly eliminate all operational risk or fraud, in either a traditional bank or stablecoin issuer. It doesn’t manage the company and doesn’t even have the real-time data necessary for continuous monitoring.

Might the FDIC end up backstopping stablecoin deposits in a crisis?

It’s certainly not impossible —with Silicon Valley Bank (SVB), for example, the FDIC did end up effectively backstopping a bunch of stablecoin deposits.

However, that happened for a series of idiosyncratic reasons and so shouldn’t be relied upon as an indicator of future actions. Specifically, the regulators were much more worried about the quantities of traditional money services business balances (e.g., Cash App) money that was caught up at SVB than they were about the stablecoin deposits per se.

Key insight: And SVB highlighted that where stablecoin reserves are held matters, since reserves at banks aren’t insured on an individual basis.

A Critical Reason Why Depositors Crave the Traditional FDIC Protections

The FDIC resolution process is predictable and fast for businesses and consumers. A stablecoin bankruptcy would be neither.

The FDIC has a long track record of making depositors whole within deposit insurance limits. It has a tried and tested process it follows and is often ready to pay out simple claims on the Monday after the Friday it closes a bank. More complex claims, such as when a customer has money in multiple “for benefit of” accounts, will take a little longer to pay in full, but will also follow a predictable process.

Key insight: There’s no comparable framework for stablecoins. Even if holders do end up getting their money back, it may take a lengthy process. That matters because the speed of resolution is important to people and small businesses with limited liquidity to weather an uncertain, protracted process.

So, even if stablecoins become more widely adopted, there are good reasons to believe bank deposit versus stablecoin is a genuine choice, not a clear winner.

You can prefer the 1:1 backing and accept the issuer risk. You can prefer the insurance wrapper and accept fractional reserves. Both are legitimate.

But beware of anyone claiming that these are fundamentally the same product with different labels. When something goes wrong — and eventually something always does somewhere in the system — this distinction is the entire ballgame.

Tokenized Deposits: Where Stablecoin Technology and Deposit Certainty Could Meet

Tokenized deposits could provide a way for banks to combine the payments efficiency of stablecoins with the benefits of insured deposits.

Could tokenized deposits, or digital representations of traditional deposits issued to a blockchain or distributed ledger, be a way for banks to offer customers the best of both worlds? Potentially, yes.

Here’s how: Tokenized deposits could offer the best of both worlds by allowing banks to offer customers something that has the functionality of a stablecoin combined with the protection of an insured deposit.

What to watch: There’s work to do on how that would fit into the FDIC’s resolution regime, and that is not yet battle-tested. However, it’s not fundamentally very hard if the FDIC is prepared to accept ownership of the token as something on which they will pay out. There’s even good historical precedent for that in the form of bearer notes, even if there are other (read anti-money-laundering requirements) reasons why banks shy away from those specific instruments today.

I don’t want to downplay the operational questions this matter raises. For example, the FDIC will want to know who it’s paying and will need a different mechanism to verify the deposit holder’s identity. It would also likely need more scalable mechanisms to pay out on claims for foreign holders. However, these are surmountable issues and should not stop the banking industry from pressing forward with tokenized deposit initiatives.

Banks Themselves Could Be the Stumbling Block for Tokenized Deposits

The most significant barrier to tokenized deposits may be the difficulty that the U.S. banking industry often has in deploying new industry-wide technology.

The greatest obstacle to the adoption of tokenized deposits may be the challenge in sparking collective action within the banking system. Tokenized deposits will not take off without clear interoperability, since no consumer will want to have to use different technologies to manage tokenized deposits from multiple banks.

At the moment, industry initiatives are a little fragmented.

We’ve seen this movie before in P2P payments, where U.S. banks, unlike their counterparts in Europe and most of Asia, effectively ceded much of the market to non-banks such as Cash App and Venmo.

Part of this is simply a coordination issue – there are many more banks in the U.S. than in most countries. But the slow adoption of Zelle in the 2010s points to the risks of the whole banking industry losing ground when the largest banks go it alone.
