Tether (USDT) is the most widely used stablecoin and the most traded cryptocurrency globally. Stablecoins are digital currencies designed to maintain a stable value by being pegged to another asset, most often a fiat currency like the US dollar, euro, or others.
Due to economic instability in many regions, people have increasingly turned to cryptocurrencies. However, traditional cryptocurrencies are highly volatile. Stablecoins like USDT offer a solution by providing the benefits of digital assets—such as fast transfers and global accessibility—without the extreme price fluctuations.
Simply put, a stablecoin aims to be a "cryptocurrency dollar." Ideally, one USDT should always be equivalent to one US dollar. But how does it achieve this, and what keeps it stable?
How Does Tether Work?
Tether Limited, the company behind USDT, states that it maintains the value of its stablecoin through a combination of corporate governance, reserves, and redeemability.
Holding Corporate Reserves
Tether holds a portfolio of assets in corporate bank accounts. These reserves are intended to back the value of all USDT in circulation.
Reserve Guarantees
According to Tether, each USDT token is backed by equivalent real-world assets. If a stablecoin is pegged to the US dollar, there should, in theory, be one US dollar (or an asset of equivalent value) held in reserve for every USDT issued.
Exchange Guarantee
The company asserts that users can exchange USDT for US dollars. This redeemability is a key mechanism that helps maintain the 1:1 peg. However, not all stablecoins rely solely on fiat reserves; some use algorithms or other collateral methods. Tether uses a mixture of reserves.
After a legal settlement, Tether Limited is now required to produce quarterly reserve reports from an independent auditor, providing more regular insight into its backing.
What Backs USDT?
The fundamental idea is simple: for every USDT issued, one US dollar should be deposited. In a perfect system, anyone could bring $100,000 to Tether and receive 100,000 USDT, or vice versa.
In reality, the composition of the reserves is more complex. Tether's reserves are divided into several categories:
- U.S. Treasury Bills: These are short-term government securities issued by the U.S. Department of the Treasury. They are considered one of the safest and most liquid assets in the world, only at risk if the U.S. government defaults.
- Money Market Funds and Bank Deposits: These are cash and cash-equivalent holdings. Their safety depends on the stability of the banking partners involved.
- Corporate Debt: This category consists of short-term loans to corporations. The risk level varies significantly depending on the creditworthiness of the borrowing companies.
- Other Investments: This includes a mix of other assets, such as precious metals, digital tokens, and loans to third-party entities. This is the least transparent category of reserves.
For simplicity, these categories can be viewed through a risk lens:
- Green (Low Risk): U.S. Treasury Bills.
- Yellow (Medium Risk): Bank deposits and corporate debt.
- Red (High Risk): Other investments and digital tokens.
The safety of USDT is directly related to the proportion of "green" versus "red" assets in its reserve portfolio. Recent reports indicate a trend toward holding more U.S. Treasuries and a slight reduction in riskier assets.
Why Doesn't Tether Just Hold Cash?
A common question is why Tether doesn’t simply hold one dollar in a bank for every USDT. The reason is economic: Tether operates similarly to a bank. It aims to generate revenue on the reserves backing its tokens.
By investing in interest-bearing assets like U.S. Treasury bonds, Tether can earn a yield. This profit model is fundamental to its business operations, though it introduces an element of risk compared to holding pure cash.
How Transparent Are Tether's Reports?
Transparency has been a long-standing concern for Tether. Since 2017, the company has published periodic reports on its reserves, but these have often been criticized for a lack of detail and independent verification. Early reports obscured bank names and were not full audits.
Currently, the company provides quarterly assurance opinions from a registered CPA firm. While an improvement, these are not the same as a full-scale audit performed under strict banking regulations. The most significant insights into Tether's operations have come from legal investigations.
A major case from the New York Attorney General's office in 2021 resulted in an $18.5 million fine and banned Tether from operating with New York residents. The investigation found two primary issues:
- Tether had misrepresented the status of its reserves, publicly claiming they were fully backed by U.S. dollars when they were not at all times.
- Tether and its affiliated exchange, Bitfinex, attempted to cover up a combined $850 million loss.
This connection to Bitfinex is crucial, as the two companies share common ownership. The investigation revealed complex financial movements between them, raising questions about the separation of corporate and client funds.
Furthermore, Tether's terms of service state that it reserves the right to delay redemptions "caused by illiquidity, unavailability, or loss of any Reserves." This clause places a significant amount of discretion in the company's hands.

How Does USDT Maintain Its $1 Peg?
Despite the controversies, USDT has remarkably maintained its peg to the dollar. Its price stability is enforced by two primary market forces:
- Direct Redemption: Large players (known as "authorized participants") can theoretically redeem USDT for dollars directly with Tether in large lots (typically $100,000 minimum). This creates an arbitrage opportunity. If USDT's market price falls below $1, these players can buy cheap USDT and redeem it for a full dollar, making a profit and pushing the price back up.
- Market Speculation: Widespread belief in the peg creates self-fulfilling stability. Traders and exchanges have confidence that USDT will return to $1, so they buy it when it dips, reinforcing the peg. This collective faith allows everyday users to freely trade USDT peer-to-peer at or near its intended value.
This system functions similarly to the historical gold standard, where people used paper currency based on the belief it could be redeemed for gold, without everyone redeeming it at once.
Frequently Asked Questions
Is Tether (USDT) a Safe Investment?
Tether is designed as a medium of exchange, not an investment. It is relatively safe for short-term transactions and transferring value due to its stable price. However, for long-term storage of significant wealth, its risks—including reserve transparency and regulatory scrutiny—make it less safe than holding cash in a fully insured bank account.
Can I Always Redeem USDT for US Dollars?
While Tether offers a redemption process for large qualified investors, it is not instantaneous or guaranteed for everyone. The company's terms of service allow it to delay or process redemptions with other assets from its reserves, not just cash. For most users, converting USDT to dollars is done through cryptocurrency exchanges.
What Is the Difference Between USDT and Other Stablecoins Like USDC?
The main difference lies in transparency and regulatory compliance. USD Coin (USDC) is issued by a regulated U.S. company (Circle) and its reserves are regularly attested to and consist primarily of cash and short-term U.S. Treasuries. Tether has faced more regulatory challenges and its reserves include a wider variety of assets, including corporate debt and other investments.
What Would Happen if Tether Lost Its Peg?
A sustained loss of the peg would indicate a crisis of confidence, potentially leading to a "bank run" scenario where everyone tries to redeem their USDT at once. This could cause significant turmoil in the cryptocurrency market, given USDT's central role in trading and liquidity.
Why Is Tether Still Popular Despite the Risks?
Tether benefits from a first-mover advantage, immense liquidity, and deep integration across the global crypto ecosystem. For many traders and users, its convenience and network effect outweigh the perceived risks, especially for short-term use.
Should I Use Tether for Long-Term Savings?
It is not advisable to use Tether or any single stablecoin as a primary long-term savings vehicle. The risks associated with the issuer's solvency and regulatory environment are higher than with traditional, insured banking products. Diversification and understanding the underlying risks are crucial.
Conclusion
Tether (USDT) occupies a controversial but central role in the crypto economy. It is not a scam in the traditional sense, as it does not promise returns, but it does operate with less transparency and higher risk than traditional financial institutions or its more regulated competitors.
The truth lies between the two extreme views of it being the future of money or an impending failure. It has proven to be a highly useful tool for transferring value globally for over six years. However, the landscape is changing, with increased regulatory scrutiny and the collapse of other major crypto projects serving as a reminder that past performance is not a guarantee of future stability.
Ultimately, using Tether is a personal risk management decision. It is excellent for intraday trading and transfers, but for significant, long-term holdings, understanding its complex backing and potential vulnerabilities is essential. 👉 Learn more about advanced trading strategies
