$1B in yield-bearing stablecoin supply in 2023.

$19B+ by the end of 2025.
In Q1 2026, yield-bearing products contributed $4.3B of an $8B increase in stablecoin supply while the broader crypto market lost 21% of its value.
That’s not a DeFi trend.
That’s a structural rotation.
Before repricing the thesis, understand what’s actually generating the yield.
Three distinct mechanisms are driving this growth, and each carries a very different risk profile.
———
① T-bill backed (Ondo USDY, $2.1B across nine chains)
Yield comes from U.S. Treasuries.
Real cash flow.
The primary risk is regulatory, not economic.
② Basis trade (Ethena USDe/sUSDe, $5.8B combined)
Delta-neutral position between spot ETH and short perps. Works when funding stays positive. When funding turns negative; as in March 2026 yields compress or disappear. The double-digit yields of 2024 were a product of favorable conditions, not a baseline.
➂ Protocol surplus (Sky USDS, $9B+)
DAO-directed revenue from lending markets and surplus buffers. When borrowing demand contracts, the yield source contracts with it.

Yield-bearing stablecoins grew 300% in 2025. In Q1 2026 alone, 22%+ growth, accounting for over half of net stablecoin supply expansion.
The acceleration isn't in dispute. What's in dispute: is the growth structural or rate-dependent?
T-bill products hold as long as Treasury yields stay attractive. Basis products hold as long as funding stays positive. Protocol surplus products hold as long as borrowing demand is strong. All three conditions held through 2024–2025. None are guaranteed in a rate-cutting cycle with weaker DeFi leverage.

➜ The Threshold That Changes Everything
21Shares projects yield-bearing stablecoins could exceed $50B in 2026, roughly 15–16% of total supply. At 25%, the passive holding case for non-yielding stablecoins starts to break down.
That threshold hasn't been reached. The trajectory suggests 2027 more than 2026.
What changes the timeline: a rate-cutting cycle pushing Treasury yields below DeFi alternatives, or a sustained bull market driving basis trade returns back toward 2024 levels.
Watch the composition of yield sources as the category grows, not just the headline number. A $50B market dominated by basis-trade products carries a very different risk profile than one dominated by Treasury-backed products.
The growth is real. The yield sources are not equal.
