"This is the most significant expansion of USDe's funding mechanism since we started." — Guy Young, Founder, Ethena Labs
Ethena Labs on September 25 announced it will back USDe with tokenized U.S. equities on Binance, marking the protocol's first extension of its delta-neutral basis trade beyond crypto assets. The move plugs into Binance's $2.9 billion equity perpetual open interest — a market that has compounded at 105% monthly in 2026 — and theoretically expands Ethena's addressable collateral universe from $2.5 trillion in crypto to over $150 trillion in public equities.
The timing is deliberate. Crypto perpetual funding rates have collapsed from 11.0% annualized in 2024 to 2.2% through August 2026, according to data cited by Unchained. Equity perpetuals on Binance averaged 17.5% annualized between May and August, offering a yield premium that the protocol's risk committee has approved for deployment. But the structural shift also layers new risks — unsecured credit exposure on bStocks, concentrated venue dependency on a single exchange, and a regulatory backdrop that saw BaFin ban USDe sales in the EU under MiCA. A June 2026 New York Fed paper warned that synthetic stablecoins like USDe can amplify market shocks through self-reinforcing deleveraging spirals, citing the October 2025 event in which USDe supply contracted more than 13% and briefly traded at $0.65 on Binance.
Ethena's original mechanism is straightforward in concept: hold a long position in a crypto asset (primarily staked ETH), short an equivalent notional in perpetual futures on a centralized exchange, and collect the funding rate differential. The two legs cancel price exposure. The yield accrues to sUSDe stakers.
The equity extension replicates this architecture using Binance's bStocks — tokenized versions of U.S. equities issued by BTech Holdings Limited, a Binance affiliate — as the spot leg, with equity perpetual futures serving as the hedge. Ethena's risk committee requires qualifying names to carry a minimum $25 million one-sided open interest over 14 days, at least 30 days of funding history, a matching tokenized stock on the same venue, and exclusion of leveraged and inverse ETFs.
Binance launched bStocks in June 2026, initially covering Nvidia, Tesla, Circle, Micron, and SanDisk. By August, bStocks held $610.6 million in value. Binance's broader Direct Stocks product reached $1 billion in holdings within 30 days of launch, providing access to 7,000+ U.S. stocks and ETFs.
The catalyst for the equity expansion is arithmetic. Crypto basis yields have fallen each year:
| Period | Bitcoin Funding Rate (Annualized) | |---|---| | 2024 | 11.0% | | 2025 | 4.9% | | 2026 (through Aug 11) | 2.2% |

sUSDe APY has tracked the decline, falling from double-digit percentages in early 2025 to approximately 5.0% as of September 12, 2026, according to Aavescan data. At 2.2% annualized crypto funding, the basis trade that built USDe can no longer sustain the yields that attracted $14.5 billion in peak supply.
Equity perpetuals tell a different story. Between May 20 and August 11, 2026, Binance equity perpetuals averaged 17.5% annualized, according to Ethena. By late August, rates had cooled to approximately 7%, with two names turning negative. The six-month average stood at 3.56% annualized — still above crypto but subject to the same compression dynamics as more capital enters.
The yield gap explains the strategic logic. It does not eliminate the question of whether equity funding rates will follow the same decay curve that crypto funding already traced.
USDe's backing has undergone a quiet structural overhaul in 2026. As of early July, according to crypto.news:
| Backing Category | Share | |---|---| | DeFi lending | 46% | | Liquid stablecoins | 35% | | Tokenized real-world assets | 11.2% | | Institutional lending | 6.9% | | Crypto basis trades | ~1% ($39M) |
Perpetual futures — the mechanism that defined the protocol — now constitute just 11% of USDe's total backing, down from the entirety at launch. The protocol has effectively become a diversified yield aggregator with a stablecoin wrapper, rather than a pure basis-trade vehicle.
Current USDe supply stands at approximately $4.9 billion, down from a peak of $14.5 billion in mid-2025. The contraction was driven by the October 2025 market dislocation and subsequent funding rate compression.
Binance's equity perpetual open interest of $2.9 billion sits within a broader tokenized equities market that reached $2.7 billion in August 2026, up from approximately $80 million a year earlier — a 422% increase, according to Binance Research.
TradFi perpetual trading volume on Binance hit $433.4 billion in August 2026, of which equity-linked contracts accounted for approximately $342.9 billion. These figures indicate meaningful liquidity, though concentrated on a single venue.
The equity perpetuals market is structurally different from crypto perpetuals in one respect that Ethena's founder has highlighted: equity markets carry a "natural positive skew of funding distribution," according to Guy Young. Stock prices exhibit a historical upward bias, which means leveraged long demand — and the funding payments that flow from it — may prove more persistent than in crypto, where directional sentiment reverses sharply.
Whether this positive skew survives the entry of systematic basis traders extracting funding remains untested at scale.
The bStocks spot leg carries a flag that Unchained identified: it represents an unsecured credit exposure to BTech Holdings Limited until a side letter is finalized. If BTech or its parent Binance entity were to face insolvency or regulatory action, the tokenized stocks could become illiquid or worthless while the short perpetual position remains open — creating a directional loss.
This mirrors the same custodial risk that existed in the crypto basis trade, amplified by the fact that both legs (spot and perp) now reside on a single exchange. In the original crypto version, spot collateral sat with off-exchange settlement custodians (e.g., Copper, Fireblocks), providing at least structural separation.
Binance is currently the only venue for the equity basis trade. The original crypto strategy could theoretically spread across multiple exchanges. The equity version cannot, as bStocks and equity perpetuals are Binance-exclusive products.
The fundamental risk remains unchanged: if funding flips negative for a sustained period, the protocol pays rather than earns. This occurred in crypto markets during the October 2025 dislocation. Equity markets have their own tail scenarios — a sustained correction or bear market could produce the same dynamic.
USDe redemptions during stress events force Ethena to unwind positions: close shorts, sell spot. In crypto, this creates a self-reinforcing spiral (sell ETH spot → ETH drops → more redemptions). In equities, the same mechanism applies but with additional friction: bStocks liquidity depends entirely on Binance's market-making infrastructure.
Germany's BaFin banned Ethena GmbH from selling USDe in the EU in April 2025, citing MiCA non-compliance. BaFin determined that USDe's delta-hedged, yield-bearing structure could not meet MiCA's 1:1 reserve requirement — a structural incompatibility rather than a remediable deficiency. It was the first enforcement action under MiCA's crypto-asset framework.
Ethena responded by routing operations through its British Virgin Islands entity, Ethena (BVI) Limited, noting that minting and redemption services were unaffected. The EU ban has not materially impacted supply, but it establishes a precedent: jurisdictions requiring fiat-asset backing for stablecoins will categorically exclude synthetic designs.
The expansion into equity-backed positions adds a layer of securities-adjacent regulatory exposure. Tokenized stocks, even when wrapped as exchange products, interact with securities law. Whether U.S. regulators view bStocks-backed USDe as having securities characteristics is an open question that Ethena has not publicly addressed.
In June 2026, the Federal Reserve Bank of New York published a Liberty Street Economics paper titled "Synthetic Stablecoins and Financial Stability" by Pablo D. Azar and Jeff Garofano. The paper examined the October 10, 2025 event, when tariff announcements triggered a broad digital asset sell-off.
Key findings:
The paper noted growing interconnections between crypto and traditional finance — including $95 billion in Bitcoin and Ether ETFs, tokenized Treasury funds, and major intermediaries expanding into DeFi — as potential transmission channels for volatility into traditional financial markets.
The equity expansion does not resolve the deleveraging spiral risk identified by the NY Fed. It diversifies the collateral across asset classes, which may reduce crypto-specific correlation. But it introduces equity market beta into a stablecoin's reserve structure — a feature that no traditional stablecoin carries and that regulators have not yet evaluated.
Ethena's equity basis trade is a rational response to a measurable problem: the crypto funding rates that built the protocol have compressed to levels that cannot sustain the yields that attracted capital. Equity perpetuals offer a demonstrably higher yield — at least for now.
The structural question is whether this represents diversification or complexity accretion. USDe has evolved from a single-strategy vehicle into a multi-asset yield aggregator, with backing split across DeFi lending, liquid stablecoins, tokenized RWAs, institutional credit, and now equity basis trades. Each layer adds optionality; each layer also adds a distinct failure mode.
The concentration on Binance as the sole equity basis venue, the unsecured credit exposure on bStocks, and the untested behavior of equity perpetual funding under stress conditions represent quantifiable risks that the current 3.56% annualized yield must compensate. Whether it does is an assessment each allocator must make independently.
What the data shows is a protocol in transition — from the elegant simplicity of a single basis trade to a complex, multi-layered reserve structure that now spans crypto derivatives, DeFi lending, real-world assets, and listed equities. The question is no longer whether the basis trade works. It is whether the institution managing it can underwrite the full risk surface of what USDe has become.
