Collateral, not yield, will decide which stablecoins win
Key Takeaways
- According to CoinDesk, yield-bearing stablecoins grew roughly 300% last year, and 21Shares expects the segment to more than triple to over $50 billion in 2026.
- CoinDesk reports that the GENIUS Act’s implementing rules are due from regulators by July 18, but the regime only takes full effect on the earlier of 120 days after final rules are published or 18 months after the Act was signed, putting full effect between late 2026 and January 2027.
- Artem Tolkachev, Chief RWA Officer at Falcon Finance, argues in the CoinDesk column that whether a stablecoin gets accepted as collateral on exchanges and lending venues, not the headline interest rate it pays, will determine which tokens actually get used.
Why Yield Is Getting All the Attention
Stablecoins that pay interest on idle balances have become one of the fastest-growing corners of crypto. CoinDesk cites figures showing yield-bearing stablecoins expanded by around 300% over the past year, with 21Shares projecting the category could exceed $50 billion by 2026. Platforms that once offered nothing on parked dollar tokens are now advertising returns of 3% or 4%, and new entrants keep pushing those numbers higher to attract deposits.
The appeal is obvious: a stablecoin that pays a coupon looks like free money compared with one that just sits there. But according to the CoinDesk column authored by Artem Tolkachev, Chief RWA Officer at Falcon Finance, this competition on yield is largely a race to the bottom. A return of a few percentage points on a dollar token is easy for a rival platform to match or beat, and it becomes even less distinctive when tokenized Treasury products offer similar returns with simpler structures. Tolkachev’s argument is that if yield is the only reason someone holds a token, they will simply move to whichever issuer offers a slightly better rate the following quarter. That kind of loyalty, built purely on price, is fragile by design.
What Actually Makes a Stablecoin Useful
The column’s central point is that yield only buys attention, while what determines whether a token is genuinely used is whether trading venues, lenders and exchanges will accept it as collateral. Tolkachev frames this as a set of practical questions: can the token be posted as margin on an exchange, does it receive a reasonable loan-to-value ratio in lending markets, and can it be moved between platforms without steep haircuts eating into its value along the way.
This distinction between a token that is merely held and one that is actively used matters for everyday holders too. A stablecoin that just sits in a wallet earning interest is, in Tolkachev’s words, inert capital — useful for accumulating a coupon but not much else. A stablecoin accepted widely as collateral lets its holder trade, borrow or hedge without needing to sell it first, which is arguably the core advantage of holding a dollar token on-chain rather than a balance in a traditional bank account. If new stablecoin supply arrives without matching improvements in how exchanges and lending venues treat that collateral, Tolkachev warns the result will be tokens that are technically in circulation, dutifully accruing their 3%, but not actually doing anything within the broader financial system — what the column describes as stranded collateral.
Regulation Sets the Floor, Not the Finish Line
Much of the coming supply growth is tied to the GENIUS Act, the U.S. framework for stablecoin regulation. CoinDesk notes that implementing rules are due from regulators by July 18, though that deadline applies to rule-writers rather than to stablecoin issuers themselves. The regime becomes fully effective on the earlier of two triggers: 120 days after the final rules are published, or 18 months after the Act’s signing, which places full implementation somewhere between late 2026 and January 2027 at the latest.
Tolkachev’s view is that clearing this federal bar will matter, since it gives issuers a legitimacy stamp that risk officers can point to. But he argues that regulatory approval alone does not automatically translate into a favorable loan-to-value ratio or broad collateral acceptance. The harder, less visible work, according to the column, involves standardizing how these dollar tokens are priced and redeemed, building risk frameworks that treat qualifying stablecoins as genuine cash equivalents, and ensuring tokens can move between venues without punitive frictions. None of this generates a marketing headline, but Tolkachev describes it as the layer that actually decides which tokens become useful working capital rather than static balances.
Hype Check
Claim: Yield-bearing stablecoins are the clear winners of the next phase of crypto growth, with the market set to more than triple to over $50 billion in 2026, according to figures cited by CoinDesk. Reality: The CoinDesk column argues that raw supply growth and headline interest rates say little about genuine usage; the deciding factor is whether exchanges and lending venues actually accept these tokens as collateral, a slower and less visible process tied partly to the phased rollout of GENIUS Act rules through late 2026 or January 2027. Verdict: Mixed.
