Banks Hate This 4% Trick

Banks Hate This 4% Trick

For decades, banks have been pampered house cats of the financial system: fat, lazy, and knocking your money around for fun.

They charge borrowers the Fed’s rates (or higher), while paying you—their actual source of funding—couch-cushion pennies.

Meanwhile, of course…

They can dump your deposits at the Fed, earn risk-free yield of 4–5%, and still keep you on starvation rations.

Three words: government-guaranteed arbitrage.

Now enter stablecoins.

Same dollars. Different wrapper. Only here, exchanges like Coinbase are handing out 4% rewards just for holding them.

How are they getting away with it? Why are banks freaking out? And what does it mean for crypto at large?

Let’s dive in.

The GENIUS Loophole

When the Genius Act was written in D.C., banks were at the table. They knew stablecoins were coming. They knew the bill would pass.

So they fought to block the one thing that terrified them most: yield.

In short, banks fought hard to stop stablecoin issuers—Circle, Tether, Paxos—from paying you interest directly.

And they won. Issuers can’t advertise yield-bearing products. Their deposits were safe(ish).

Summer Mersinger (ex-CFTC, now Blockchain Association CEO) called it “the compromise.”

Washington sausage-making 101.

The banks weren’t thrilled, but they thought they’d done enough to hobble stablecoins.

But they missed something.

The law said issuers couldn’t pay yield. It said nothing about third-parties like exchanges.

So Coinbase, Kraken, and Gemini stepped right in. They don’t call it “interest.” They call it “rewards.”

And suddenly, stablecoin holders are earning 4% while bank depositors twiddle their thumbs at <0.7%.

Look, the banks agreed to this language. They were in the room.

And now they’re mad.

As you read this, they’re lobbying to slam the loophole shut with amendments in the upcoming crypto market structure bill:

AKA, the CLARITY Act.

But Who Will Lend the Money?

Banks love scare tactics.

They say: “If your money goes into stablecoins, who’s going to make loans? Who’s going to fund mortgages?”

They keep pushing this idea that your deposits are sacred fuel for lending—as if every dollar you put in magically gets turned into a mortgage for your neighbor.

That’s not how modern credit works.

Modern banks don’t sit around waiting for your $1,000 so they can lend $900 of it.

They create loans first (literally typing new deposits into existence on their balance sheet) and then worry about balancing reserves and funding later.

Here’s what else they don’t tell you:

  1. Big banks don’t even make most of the loans anymore. In big areas like mortgages and corporate borrowing, non-banks have taken over.
  1. Even in business lending, banks’ slice is shrinking. Just a few years ago, banks handled about 44% of corporate loans. Now it’s closer to 35%. The rest comes from outside lenders.
  1. In mortgages, banks are no longer king. Most new home loans in America today come from non-bank mortgage companies, not your local branch.

In other words… 

Lending markets—especially with DeFi solutions coming online too—will be fine.

And when deposits flow into stablecoins? The money doesn’t vanish. It goes into T-bills and bank reserves—the same plumbing that underpins credit markets.

What really dies is the banks’ spread: paying you peanuts while pocketing billions on the same dollars.

Think of yield-bearing stablecoins as Money Market Funds 2.0. We already ran this experiment. MMFs grew by trillions. Credit didn’t collapse.

If anything, it got cheaper for everyone not named Jamie Dimon.

The Real Stakes

Yes, the banks could fix this tomorrow by raising deposit rates.

But they won’t—because they’ve grown addicted to their profit engine: your money.

Which is why they’re fighting tooth and nail to shut the loophole.

But it’s too late. The genie is out of the bottle.

Money found a freer wrapper.

And they’re just getting started.

Stablecoins are already pressuring bank deposits. Next they’ll come for credit card fees. After that? Retirement accounts.

This is what Mersinger called the “new playbook.”

And it’s only just beginning.
