Stablecoin Yield: How It Works and What Can Go Wrong

Stablecoins were created to emulate fiat currency by pegging 1:1 to assets like the U.S. dollar, allowing businesses to send tokens domestically and internationally in minutes without the high fees standard transfers can bring. While this is their main superpower, it isn’t the only one. Some crypto exchanges and platforms offer yields on stablecoin balances that can earn interest rates similar to the ones found in many treasury and savings accounts.

While this is an alluring concept, it can add regulatory and liquidity risk to the money businesses need for key supplier payments. In this article, we’ll explore how stablecoin yield works, the complex way it’s currently regulated, and the pros and cons associated with it.

If you’re interested in trying stablecoins, but you aren’t sure if you’re ready to take on the risks of earning yield on balances, take a look at Slash. Slash is a financial platform that offers stablecoin payment rails for those who want to save time and money on transfers, while also offering a SIPC-protected treasury account that can earn up to 3.88% yield on idle balances.¹, ⁴, ⁶

Key Takeaways

Stablecoins don’t generate yield by existing, since interest on the reserves belongs to the issuer. Any yield you earn comes from placing the token into a separate revenue-producing system.
It’s important to know where a yield comes from, because some returns are much more reliable than others. Yield should be traceable to borrower interest, trading fees, or identifiable assets.
The GENIUS Act bars prohibited issuers from paying holders yield for simply holding a stablecoin, but exchanges, wallets, and lending platforms aren’t currently included.
The Clarity Act would have extended that restriction to all digital asset service providers and their affiliates, but it failed a Senate procedural vote on September 15, 2026.
Stablecoin balances can’t carry FDIC insurance, so a custodian's insolvency or a withdrawal freeze can leave a business without access to its funds.

Understanding Stablecoin Yield

A stablecoin is a digital token designed to maintain a stable value relative to another asset, most commonly the U.S. dollar. Fiat-backed stablecoins such as USDC and USDT generally rely on issuer reserves, while crypto-backed options may use different collateral and market mechanisms. Either way, stablecoins don’t generate income merely because they exist. Interest usually comes from the cash, Treasury bills, and other assets fiat-backed issuers hold in reserve.

A customer only earns yield when the stablecoins are placed into another revenue-producing structure or when a crypto platform offers a promotional reward. Coinbase, as an example, offers 3.75% when you hold USDC within their platform. That return comes from Coinbase rather than USDC itself. Behind the scenes, platforms may earn money for that yield in one of a few ways:

Lending: An exchange lends customer-deposited stablecoins to borrowers. Borrowers pay interest, and depositors receive part of that total.
Liquidity provision: A holder supplies stablecoins to a decentralized exchange or market-making pool and receives part of the trading fees.
Real-world assets and trading strategies: A platform may invest through tokenized treasury or money-market products, private credit, or other trading strategies. Returns then depend on interest rates and derivatives rather than the stablecoin’s peg.

By-and-large, these work through smart contracts, which are self-executing programs stored on a blockchain. They can accept deposits, calculate shares, adjust rates, enforce rules, and distribute returns automatically.

So, the important question is not only, “What is the APY?” but, “Where does it come from?” A good yield should be traceable to borrower interest, trading fees, or identifiable assets. Returns funded mainly by newly issued reward tokens or an undisclosed strategy may not be as reliable as you’d hope.

How the U.S. Government Regulates Stablecoin Yield

Stablecoin yield happens to be a hot topic among United States regulators. As of September 2026, the main federal framework for stablecoins is the GENIUS Act. It states that a permitted stablecoin issuer may not pay a holder interest or yield (whether in cash, tokens, or another form) solely in connection with holding or using the stablecoin. In layman’s terms, an issuer can’t say a stablecoin bears interest, then pass reserve income directly to customers just because they have that coin.

However, this law only applies to issuers like USDC and USDT. It doesn’t affect exchanges, wallet providers, lending platforms, or other third parties paying customers from their own revenue or deploying their coins into a separate product.

Whether you want to call that a loophole or an intentional distinction, this means that users can still earn stablecoin yield normally, albeit through an extra step. An exchange like Kraken might therefore describe payments as rewards, require customer activity, lend the coins through a separate product, or route them into decentralized finance.

The GENIUS Act is scheduled to take effect on January 18, 2027, or 120 days after federal regulators issue final implementing rules if that happens earlier. Adjustments are actively being suggested; in April, the FDIC proposed a rule that would bar an issuer from paying yield to holders through an arrangement through a related third party. This rule is still pending, partly because focus was directed elsewhere: the Clarity Act.

The Digital Asset Market Clarity Act

The Senate version of the Clarity Act would have drawn a clearer line. Section 404 extended the passive-yield restriction to all digital asset service providers and their affiliates, essentially banning compensation paid solely for holding a stablecoin.

At the same time, it preserved activity-based incentives tied to payments, conversions, collateral, governance, staking, loyalty programs, and other actual platform use, provided the reward doesn’t function like deposit interest. It also required disclosures that stablecoins aren’t government guaranteed or FDIC-insured.

The Clarity Act didn’t advance. On September 15, 2026, the Senate voted 49–50 against it, short of the required 60 votes. It was a procedural vote rather than a vote on the bill’s merits, but the measure stopped in its tracks either way, leaving the GENIUS Act as the presumptive regulatory framework going forward.

Advantages and Risks of Stablecoin Yield

While businesses have the potential to earn a good amount of returns through stablecoin yield, the process isn’t without its risks and uncertainties. To help you determine whether it’s a worthwhile endeavor, let’s look at some pros and cons:

Advantages:

Productive digital liquidity: The most obvious benefit is the money you can gain from assets that wouldn’t normally come with yield. A company that already receives stablecoins can earn a return while waiting to pay a contractor, rather than converting that money into cash, putting it in a savings account, then switching it back soon after.
Programmability and round-the-clock access: Onchain markets can operate outside bank hours and automate deposits, withdrawals, collateral, and interest calculations. Businesses get the flexibility to move money outside of banking hours in ways that typical accounts usually can’t.

Risks

Depegging and reserve problems: While it’s uncommon, a stablecoin can fall below $1 if confidence weakens in its reserves, issuer, custodian, or redemption process. Even a temporary depeg can reduce collateral value or trigger liquidations at a loss.
Custody failure: If a centralized provider becomes insolvent or freezes withdrawals, the user may hold an unsecured claim and be unable to recover their funds immediately. Stablecoin balances cannot be insured by the FDIC or similar agencies, since crypto is treated as property rather than currency.
Smart contract issues: Smart contracts are vulnerable to bugs and hacks, and because blockchain transfers are difficult to reverse, it can be essentially impossible to recover lost tokens.
Variable liquidity, rates, and regulation: Yields can change daily as demand and incentives move. A high advertised rate may come with lockups, withdrawal queues, or thin market liquidity. Your rate may also shift massively based on U.S. regulations, since an unexpected update to the GENIUS framework can change everything about the yield you’re earning overnight.

Frequently Asked Questions

How is stablecoin yield taxed?

Yield is generally treated as ordinary income at its US dollar value on the date you receive it, and that value becomes your basis in the tokens. Because the IRS treats digital assets as property rather than currency, converting or spending them later can produce a separate capital gain or loss. That said, rewards structured as promotional payments may be treated differently from interest, so it's worth having a CPA look at how your specific program is characterized.

What does SIPC protection cover?

SIPC protects customers from a failed member broker-dealer, covering missing securities and cash up to $500,000 with a $250,000 sublimit on cash. It doesn’t protect against investment losses, so a money market fund that falls in value is not a covered event.

What’s the best stablecoin for businesses?

By far, the two most commonly used stablecoins are USDC and USDT. The main difference between the two is that USDT isn’t supported within the EU due to MiCA, while USDC is. The more widely adopted a given stablecoin is, the more likely it is that your clients will be familiar with it, so popular options like these two are a good bet.
