People don’t pull their money out of banks just because they’re mad at banks. It happens when something smarter comes along — like stablecoins. They let you move dollars faster, send them anywhere, plug into all sorts of apps, and stash the actual backing in places banks can’t touch.

That’s why Standard Chartered’s recent warning, picked up by Reuters, landed with a thud. They’re talking about hundreds of billions of U.S. deposits leaving for stablecoins, and regional banks could take the hardest punch. This isn’t some crypto fantasy. It’s actually changing how money moves behind the scenes.

The simplest truth: stablecoins are a payments layer attached to a reserve balance sheet
Here’s the thing about stablecoins: they’re not just some digital token floating around. They’re built on a pretty simple setup—a payment layer that’s anchored to a real reserve balance sheet.
Think of stablecoins as having two sides.
First, there’s the on-chain token supply. These tokens aren’t just numbers; they’re liabilities for the issuer. Each one is a promise—a claim that you can actually swap it for dollars, either straight from the issuer or through their partners.Then you’ve got the off-chain reserves. That’s where the issuer keeps their assets. The way they manage these reserves matters. They might leave the money sitting in bank accounts, or shift it over to Treasuries and money markets. The choice they make here decides whether funds stay in banks or start moving elsewhere.
Honestly, this decision about reserves is what really drives deposit drain. That’s the core of it all.
What actually happens when a user “moves money into stablecoins”
You put in your dollars, and that mints stablecoins. The reserves then move over to T-bills. Those stablecoins start circulating—people use them like regular money for payments. When someone wants to cash out, the whole process runs backward.

Now let's dive deeper
Step 1: You start with deposit money, not “cash”
Your bank balance isn’t really yours sitting in a vault somewhere. It’s money the bank owes you. Banks use those deposits to hand out loans and buy up securities—it’s their cheapest way to get cash.

So when people start pulling their money out, banks don’t just lose customers. They lose the fuel that keeps their whole business running.

Step 2: Minting stablecoins changes where the dollar sits in the system
When you mint a stablecoin, you’re basically moving your dollars out of your own bank account and into the hands of the stablecoin issuer. Now, what happens next depends on where the issuer parks those reserves.
Case A: Issuer keeps reserves in banks
If the issuer mostly leaves the money sitting in regular bank accounts, your dollars don’t really leave the banking system. They just move from your name to the issuer’s, still living inside some bank’s books.
Case B: Issuer puts reserves in Treasuries and similar stuff
But if the issuer uses your money to buy short-term Treasuries, repos, or government-backed money market funds, that’s a different story. Now, your dollars stop helping banks make loans and start flowing into the Treasury market instead.

That’s why you hear analysts say, “Not much money is coming back to banks.” If most of the reserves are in Treasuries, it’s really a one-way trip—money leaves the banks and doesn’t circle back.

Step 3: Stablecoins become “high-speed money wrappers” with a Treasury-backed core
Here’s the part most people miss: at scale, a major fiat-backed stablecoin starts resembling a digitally native money market wrapper, except it’s tradable and transferable on-chain.
That is powerful because it combines:
Treasury-style reserve safety (short duration government assets)Instant portability (send anywhere, anytime)Programmability (payments, escrow, settlement logic)Composability (apps can integrate stablecoins like an API)
The result is a dollar instrument that behaves like “checking money” in user experience, but funds itself like “Treasury money” in reserves.
Step 4: Circulation moves payment activity off the traditional bank-to-bank stack
Once minted, stablecoins circulate through:
P2P transfersMerchant paymentsExchangesDeFi settlementRemittancesPayroll or treasury ops for businesses
Every time the stablecoin changes hands, that’s a payment. You don’t need to tap into the old bank payment rails for each one. The stablecoin network becomes the main layer, and banks end up on the sidelines, just handling the cash-in and cash-out points.

That’s why you can’t really separate the “deposit story” from the “payments story.” Banks held onto deposits for so long because they controlled payments. But when payments move somewhere else, deposits follow right behind.
Why regional banks get hit first, not because they’re “worse,” but because they’re built differently
Big banks and regional banks don’t run the same business model.
Regional banks tend to rely more on:
deposits as their primary funding basetraditional lending spread as a major profit enginefewer alternative fee engines than mega-banks
So if deposits leak out, regional banks face a harsher set of choices:
raise deposit rates to retain funds (margins compress)shrink the balance sheet (less lending capacity)borrow wholesale funding (more sensitive to stress, higher cost)
That’s why warnings often emphasize that the pain isn’t evenly distributed.

The accelerant: “rewards” can turn stablecoins into a deposit magnet
Even without hype, stablecoins offer convenience. But convenience plus incentives is a different game.
If stablecoin ecosystems can offer reward-like benefits (directly or indirectly), the stablecoin starts to compete with checking and savings products on user economics, not just on speed.
You don’t even need a debate to see the mechanism:
user holds stablecoin as a balanceissuer holds Treasuriessomeone shares part of the yield or offers perksdeposit retention becomes harder, especially for rate-sensitive users
This is where policy and design collide, and why the “deposit flight” narrative is so politically explosive.

The second-order effect: deposit drain isn’t the only risk channel
At large scale, stablecoins can also transmit stress into the short-term funding world.
Because if reserves are concentrated in short-term government assets, then in a heavy redemption scenario:
issuers may need to liquidate or roll reserves aggressivelyliquidity conditions in short-term markets can tightenstablecoin redemption pressure can echo into broader funding plumbing
This isn’t fear-mongering. It’s the same structural truth that finance learns repeatedly: when something becomes system-scale, it becomes system-relevant.

The takeaway: stablecoins aren’t “killing banks,” they’re rerouting where money lives
Here’s what matters: stablecoins aren’t putting banks out of business, they’re just changing where the money sits.

If you only remember one thing, let it be this: Stablecoins don’t erase dollars. They just move them—from regular bank accounts into reserves held by issuers, usually parked in Treasuries. They also shift payments onto a global, programmable platform.

So when people talk about deposits leaving banks, it’s not just about crypto. It’s about how banks get their funding, how payments move, and what’s happening in the Treasury market—all of it, all at once.

If stablecoins become the default checking account, what’s the one bank product that dies first: debit cards, savings accounts, or the entire “free checking” model?
