Introduction
In his latest blog post, Arthur Hayes, former BitMEX CEO and prominent crypto thinker, examines the vulnerabilities of Tether (USDT) and introduces Ethena's synthetic dollar as a potential successor. This analysis explores:
- The fragility of Tether's banking relationships
- Why US regulators view Tether as problematic
- How Ethena's decentralized model addresses these weaknesses
The Precarious Position of Tether
Banking Dependencies
Tether's entire operation hinges on maintaining banking partnerships for:
- Dollar Onboarding: Creating new USDT requires fiat deposits
- Reserve Custody: Holding collateral for existing USDT
- Redemptions: Processing withdrawals back to fiat

Weak Link in the Chain
Tether's primary banking partners share critical vulnerabilities:
| Bank | Jurisdiction | Fed Master Account? |
|---|---|---|
| Britannia Bank | Bahamas | No |
| Cantor Fitzgerald | USA | No (Primary Dealer) |
| Deltec Bank | Bahamas | No |
Without access to Federal Reserve master accounts, these institutions rely on larger correspondent banks—creating a single point of failure where regulators could pressure Tether's operations.
Why US Institutions Oppose Tether
Federal Reserve's Concerns
Tether operates as a full-reserve bank, holding ~$81B in:
- Money market funds
- Short-term Treasury bills
This creates two problems for the Fed:
- IORB Costs: The Fed must pay interest on reserves (currently ~5.3%), with Tether capturing this yield while paying 0% to users
- QT Complications: Tether's growth counteracts the Fed's quantitative tightening goals
Treasury Department's Worries
As the 22nd largest Treasury holder globally, Tether poses systemic risks:
- Sudden liquidation could destabilize bond markets
- Concentrated holdings in short-term bills exacerbate funding volatility
The Ethena Alternative
Synthetic Dollar Mechanics
Ethena's USDe achieves stability through:
- Collateralization: ETH/stETH holdings
- Hedging: ETH/USD perpetual swaps locking dollar value

Yield Generation
| Source | Estimated APR | Risk Factors |
|---|---|---|
| ETH Staking Yield | 4% | Slashing/smart contract |
| Perp Funding Rates | 20% | Extended negative periods |
Unlike Tether, Ethena distributes ~80% of this yield to sUSDe stakers through transparent on-chain mechanisms.
Competitive Advantages
- Decentralized: No single bank can disable operations
- Profit Sharing: Exchanges invested early (Binance, OKX, etc.)
- Scalability: Currently ~$10B TVL, with room to grow alongside crypto markets
FAQ: Tether vs. Ethena
Q: Could Tether really collapse overnight?
A: Yes—if correspondent banks withdraw services, USDT would lose creation/redemption capabilities, though existing tokens might continue trading.
Q: How is Ethena different from Terra's UST?
A: UST relied on algorithmic balancing with LUNA, while USDe generates yield from verifiable ETH staking and derivatives markets.
Q: What limits Ethena's growth?
A: Currently constrained by exchange perpetual swap OI (~$120B across ETH/BTC), though this will expand with crypto market growth.
Q: Who audits Ethena's reserves?
A: While not yet fully decentralized, Ethena uses transparent blockchain accounting versus Tether's opaque banking arrangements.
Conclusion
Hayes argues that Ethena represents the next evolution of stablecoins by:
- Removing banking single points of failure
- Sharing profits with users and exchanges
- Leveraging crypto-native yield sources
While Tether currently dominates with $100B+ market cap, its centralized dependencies make it vulnerable to regulatory disruption—a weakness Ethena's architecture systematically addresses.
