Is Stablecoin Yield a Backdoor Subsidy?

Originally published at DC Journal on Inside Sources. 

President Trump just tossed a political match into a financial tinderbox: the fight over whether crypto platforms can pay “interest-like” rewards on stablecoins while banks are stuck playing by bank rules. 

In a late-night post, Trump blasted banks for “undermining” the stablecoin framework and urged them to cut a deal with crypto, turning a technical policy dispute into a White House priority.

The trouble is that the “deal” being floated isn’t free-market competition. It’s a regulatory workaround that tilts the playing field and risks draining deposits that fund real-world lending.

Stablecoins can be genuinely useful. As a payments tool, a well-run, fully redeemable stablecoin can reduce settlement and exchange frictions. The GENIUS framework was supposed to keep stablecoins in that payments lane, not turn them into deposit accounts wearing a crypto costume.

The current fight is about yield, and yield changes everything. Federal Reserve Vice Chair of Supervision Michelle Bowman recently testified before the Senate Banking Committee that banks should have more flexibility when competing with non-banks.

Here’s the core problem: the law says stablecoin issuers can’t pay interest, but it leaves room for exchanges and affiliates to pay “rewards” on stablecoins held on-platform. That’s not a loophole around the edges; it’s a tunnel under the whole policy.

The Bank Policy Institute has been warning about this for months: if intermediaries can pay interest-like returns, the prohibition becomes “easily evaded,” and stablecoins become a direct substitute for bank deposits without being regulated like deposits.

According to a report on the push, advocates are urging Congress to close the stablecoin “backdoor,” citing a Treasury estimate that as much as $6.6 trillion in deposits could shift if stablecoin rewards persist. Deposits are the oxygen supply for community lending: mortgages, small business credit, and agricultural finance. Pull the oxygen out and don’t be shocked when the patient gets woozy.

This is where the economics gets ignored in favor of shiny slogans like “Americans should earn money on their money.” Sure. But how do they earn it? Interest isn’t a magic gift. It’s a price that coordinates resources.

Historically, warehousing and finance evolved together. People stored valuable goods (think grain), and over time, warehouse receipts became tradable claims. When stored value could be pooled, relied on, and put to productive use, returns emerged.

Modern banking is the grown-up version: banks pay interest because deposits fund lending and liquidity services, and because banks operate inside an expensive regulatory box — capital rules, liquidity rules, supervision, exams, resolution regimes.

Stablecoins — at least as GENIUS-style “payment stablecoins” — are not supposed to fund lending. Their reserves are meant to be cash-like and liquid. So where does “yield” come from? Mostly from reserve income and platform economics, not from financing Main Street. 

BPI’s warning is blunt: If stablecoins are backed by Treasurys, depositors shift from funding private credit to funding government debt, shrinking bank credit availability.

And yes, there’s research pressure behind the concern. The Consumer Bankers Association points to work concluding that the best way to protect credit availability is to close the yield loophole that allows intermediaries to pay it.

Meanwhile, this fight is now actively jamming up Capitol Hill. Reuters reports the companion market-structure legislation is hitting repeated impasses because banks won’t accept a compromise that still allows reward-style yield, warning it would accelerate deposit flight.

So what’s the principled path? There are only two honest options.

An option is to close the loophole. If stablecoins are payment instruments, then “interest-like” inducements should be prohibited whether paid by issuers, affiliates or exchanges. Otherwise, Congress is effectively inviting regulatory arbitrage — the oldest trick in modern finance, now dressed up as fintech virtue.

The second option is the better one: deregulate banks to allow them to compete. If policymakers truly want innovation in payments and savings products, stop treating banks like utilities and then acting surprised when competitors sprint around them. The answer to overregulation is not to create a loophole for the new kids. It’s to remove unnecessary burdens on the old ones, letting competition happen on price, service, and technology.

What we should not do is run a two-track system: banks handcuffed by dense regulation, stablecoin platforms free to mimic deposits when profitable and dodge bank obligations when inconvenient. That’s not a free market. That’s government picking winners — by fiat, ironically enough.

Stablecoins may well improve payments. Let them win on payments. If they want to compete for deposits by paying yield, then either they should face equivalent rules, or banks should be freed to compete. Anything else is a backdoor subsidy masquerading as innovation.
