The rise of stablecoins has reshaped the digital economy, but not all stablecoins are built the same. Among them, Tether (USDT) stands as the largest by market capitalization, yet its structural vulnerabilities run deep—especially in its reliance on traditional financial institutions. In contrast, Ethena (USDe) emerges as a next-generation, synthetically backed dollar alternative that sidesteps many of these systemic risks. This article explores why Tether is both a triumph and a ticking time bomb—and how Ethena could redefine the future of on-chain dollars.
The Flawed Foundation of Tether
Tether’s model is simple: for every USDT in circulation, $1 is held in reserve, primarily in bank accounts and short-term instruments like U.S. Treasury bills. While this sounds secure, it creates a critical dependency—the traditional banking system.
To function, Tether must:
- Create USDT: Accept fiat deposits through partner banks.
- Hold Reserves: Store those dollars in bank accounts.
- Redeem USDT: Allow users to cash out into real dollars.
Without access to banking infrastructure, none of this is possible.

But here’s the catch: Tether’s banking partners are not core players in the U.S. financial system.
Who Backs Tether?
Tether’s known banking partners include:
- Britannia Bank & Trust
- Cantor Fitzgerald
- Capital Union
- Ansbacher
- Deltec Bank and Trust
Of these, only Cantor Fitzgerald is U.S.-registered, and none hold direct master accounts at the Federal Reserve. This means Tether operates through correspondent (or "nostro") banking relationships, relying on intermediaries to move dollars across borders.
When a non-U.S. bank wants to transfer USD internationally, it must use a U.S. bank with a Fed master account to settle via the Fedwire system. If that U.S. bank decides to terminate the relationship—due to regulatory pressure, reputational risk, or political influence—Tether loses its lifeline.
And unlike major financial institutions, Tether has no political insulation or systemic importance to guarantee protection.
Why the Fed and Treasury Dislike Tether
Tether isn’t just exposed to banking risk—it’s structurally at odds with U.S. monetary policy.
Tether as a "Narrow Bank"
From a traditional finance (TradFi) perspective, Tether functions like a narrow bank—a fully reserved institution that accepts deposits but doesn’t lend. It collects dollars and parks them in low-risk assets like money market funds and T-bills.
While this sounds safe, it creates a problem: Tether earns interest from the U.S. financial system without contributing to credit creation.
Here’s how:
- Tether invests ~$81 billion in U.S. Treasuries and repo agreements.
- These instruments are tied to the Reverse Repo Program (RRP), where the Fed pays interest to stabilize short-term rates.
- Tether earns near the upper bound of the federal funds rate—but pays 0% to USDT holders.
This creates a massive net interest margin (NIM) for Tether—essentially free money from the Fed—while doing nothing to stimulate the real economy.
Meanwhile, the Federal Reserve spends billions annually paying interest on reserves (IORB) to commercial banks to keep liquidity in check during quantitative tightening (QT). If more narrow banks like Tether emerge, they’d extract even more yield from the system—without lending, without risk-taking, and without accountability.
The Fed doesn’t like this. Neither does the Treasury.
The Treasury Market Risk
Tether is now one of the top 22 holders of U.S. Treasury bills. If its banking partners suddenly cut ties, Tether could be forced to liquidate assets rapidly to meet redemption demands.
Even a modest sell-off could destabilize the already fragile Treasury market.
Since 2020, Treasury liquidity has declined sharply:
- A small wave of selling can trigger volatility.
- Bond prices could drop fast; yields could spike.
- Because global debt markets are priced relative to U.S. Treasuries, the ripple effects would be worldwide.
Treasury Secretary Janet Yellen can’t afford such chaos. While she might temporarily freeze redemptions or grant breathing room during a crisis, she won’t help Tether find new banking partners.
In fact, she’d prefer Tether didn’t exist at all.
Tether’s Profitability vs. Traditional Banks
Despite its fragility, Tether is wildly profitable—especially per employee.
According to analyst estimates:
- Tether generates ~$62 million in revenue per employee.
- Compare that to major "Too Big To Fail" banks like JPMorgan or Bank of America: none come close.
This absurd efficiency stems from:
- Near-zero operational costs.
- High-margin arbitrage between Fed policy rates and stablecoin issuance.
- No need to pay depositors.
But here’s the irony: Tether’s profitability depends entirely on banks that earn far less—and resent it.
If a major U.S. bank launched its own stablecoin:
- It would have immediate regulatory approval.
- It could issue tokens backed by real balance sheets.
- Users would trust JPM Coin more than USDT—because it’s backed by an institution “too big to fail.”
And unlike Tether, it wouldn’t rely on offshore banks or regulatory gray zones.

The barrier isn’t technical—it’s already possible to clone Tether’s smart contracts. The real barrier is incentive alignment.
But as crypto adoption grows and bank valuations stagnate, expect a major financial institution to enter the stablecoin race soon.
Why We Need a New Kind of Stablecoin
Tether proved the demand for on-chain dollars. But its flaws are clear:
- Users get no yield—despite generating massive profits for issuers.
- It can be shut down overnight by a bank or regulator.
Ethena (USDe) was built to solve both problems.
Meet Ethena: A Synthetic Dollar
Ethena creates a synthetic U.S. dollar (USDe) using two components:
- Staked ETH (e.g., stETH) – earns yield from Ethereum’s proof-of-stake rewards.
- Short ETH/USD perpetual swaps – earns funding rate income when ETH trades at a premium in futures markets.
By combining these, Ethena locks in a dollar-equivalent value while capturing yield—without relying on banks or Treasuries.
How USDe Maintains Its Peg
Ethena uses Authorized Participants (APs)—trusted entities that mint and burn USDe.
Minting USDe:
- AP deposits stETH (e.g., worth $10,000).
- Ethena shorts $10,000 worth of ETH/USD perps to hedge price risk.
- Protocol issues 10,000 USDe to AP.
Burning USDe:
- AP returns 10,000 USDe.
- Ethena closes part of its short perp position.
- AP receives back stETH (minus fees).
This mechanism ensures that every USDe is overcollateralized and hedged against ETH volatility.
Why USDe Pays High Yield
USDe holders earn yield from two sources:
- ETH Staking Yield (~4% APY) – paid in ETH by the Ethereum protocol.
- Perpetual Funding Rates (~positive long-term) – because ETH is deflationary and demand for leverage is high.
When funding rates are positive (which they’ve been ~80% of the time), longs pay shorts—meaning Ethena earns income.
This yield is passed directly to users who stake USDe (sUSDe), creating strong demand and upward price pressure on exchanges like Curve.
FAQ: Common Questions About Ethena and Tether
Q: Can Ethena really replace Tether?
A: Not overnight—but yes, over time. As crypto markets grow, so will ETH perpetual open interest—the ceiling for USDe supply. With exponential growth in derivatives volume, Ethena could scale into dominance.
Q: Isn’t Ethena just another UST waiting to collapse?
A: No. Unlike Terra’s UST, which relied on algorithmic incentives and collapsing token value, Ethena’s yield comes from real economic activity: staking rewards and derivative funding. There’s no Ponzi-like structure.
Q: What happens if funding rates turn negative?
A: Ethena has an insurance fund ($16M+) made up of USDC, USDT, stETH, and LP positions. It acts as a backstop during volatility or negative carry periods.
Q: Is Ethena decentralized?
A: Not fully—but it doesn’t need to be yet. Its counterparties are major CEXs (like Binance, OKX, Deribit) that have skin in the game. As adoption grows, decentralization can follow.
Q: What backs USDe?
A: Real assets—staked ETH and perp hedges—not promises or unregulated reserves. Transparency comes from on-chain data and public risk disclosures.
Q: Can banks destroy Ethena like they could Tether?
A: No. Ethena operates entirely within crypto markets—no bank accounts, no correspondent banking, no Fed dependency.
Risk Factors for Ethena
While innovative, Ethena isn't risk-free:
- Counterparty Risk: Relies on centralized exchanges (CEXs) for perp positions. If a CEX fails to pay out, losses occur.
- Smart Contract Risk: Bugs in minting/redeeming logic could be exploited.
- LSD Risk: stETH or other liquid staking derivatives could depeg or face slashing.
- Negative Funding: Prolonged bear markets may flip funding rates negative, eroding yields.
However, these risks are transparent and mitigated through diversification, audits, and the insurance fund.
Governance and Valuation Outlook
Ethena plans to launch a governance token, giving holders a stake in protocol revenue and direction.
Based on current yield splits:
- ~80% of income goes to sUSDe stakers.
- ~20% accrues to the protocol (future treasury).
With an assumed 50% staking ratio and $1B+ supply, annual protocol revenue could reach hundreds of millions—making Ethena one of DeFi’s most valuable protocols.
Compare this to Ondo Finance trading at 600x revenue multiples: Ethena could see similar investor appetite given its scalable yield model.
Final Thoughts: The Future of On-Chain Dollars
Tether revolutionized crypto—but its Achilles’ heel is clear: it depends on a system that resents it.
Ethena offers a new paradigm:
- No banks.
- No political risk.
- Real yield for users.
- Built for the crypto-native economy.
