Is USDT Safe to Hold Long Term? Risks, Reserves, and Regulation Explained

Is USDT safe to use long term? Yes—it can be, but it’s not risk-free.

USDT (Tether) holds the largest share of the stablecoin market and acts as a cornerstone of crypto trading.

But many users worry about its transparency, backing, and future regulatory treatment.

This article explores whether those concerns matter. And we’ll break down the facts, trends, and expert opinions to help you decide if USDT is a safe long-term option.

What Is USDT and How Does It Work?

USDT is a stablecoin pegged to the U.S. dollar at a 1:1 ratio. Each token represents one dollar’s worth of value.

And here’s how it works:

• You send a dollar to Tether Limited and receive one USDT in return, ready to use on crypto networks. For most users, the easy way to buy USDT is through crypto exchanges that support fiat deposits or crypto swaps.

• Tether holds dollar reserves equal to the number of USDT tokens issued—called proof of reserves—to back each token.
  
• They issue new tokens when users deposit dollars and destroy (“burn”) tokens when users cash out.
  

But it’s centralized. Tether controls minting, burning, and even freezing of tokens on blockchains like Ethereum, Tron, and Solana.

This setup offers stability and fast transfers. And because USDT lives on multiple chains, you can move money quickly without volatility risk.

The Controversies and Concerns Around USDT

USDT has a history of transparency problems. Reporting shows Tether used risky commercial paper, not just cash, while claiming full dollar backing. That led to a $41 million CFTC fine in 2021 for misleading claims.

And there’s more: USDT reserve reports are unaudited snapshots. Tether said it would get a full audit, but never did.

But it’s not just audits. Tether was involved in a scandal involving Bitfinex, where it allegedly used USDT reserves to cover up an $850 million shortfall—settled with an $18.5 million NYAG penalty.

And critics warn of potential price manipulation. Studies found bitcoin rallies often followed large USDT issuances—raising suspicions of market influence.

Plus, USDT is a magnet for illicit use. Law enforcement reports say it’s often used for money laundering, sanctions evasion, and other illegal activity—estimated at billions annually.

These controversies can shake confidence. And if trust falls, it could threaten USDT’s peg and overall market stability.

How Are USDT’s Reserves Managed Today?

USDT reserves are now more transparent and diversified than before.

Tether released a Q1 2025 attestation confirming its reserves exceed liabilities by $5.6 billion. An independent accounting firm, BDO, verified the breakdown as of March 31, 2025. And the company holds nearly $120 billion in U.S. Treasuries—making it a major U.S. government debt holder—along with other liquid assets .

Here’s the latest reserve mix:

• Cash & equivalents (≈70–85%) – Composed of U.S. Treasuries, reverse repos, money market funds, and bank deposits.
  
• Other assets (≈15–30%) – Includes corporate bonds, secured loans, precious metals, Bitcoin, and other investments.

But it’s still not a full audit. Tether is engaging with a Big Four firm, and CEO Paolo Ardoino says securing a full audit is “top priority” under the current U.S. administration. And critics still argue that attestations, while helpful, don’t replace a thorough audit.

Regulatory Risks and Legal Exposure

USDT faces rising scrutiny from both U.S. and EU regulators.

In the U.S., Congress is moving ahead with major stablecoin rules. The GENIUS Act passed the Senate, and the STABLE Act is in the House. These laws will require issuers to hold liquid assets, undergo audits, comply with AML, and get federal or state charters. But both acts currently allow foreign issuers like Tether a grace period or exemption—potentially giving them an edge over U.S.-based stablecoins.

And the EU is enforcing the MiCA regulation since December 2024. MiCA demands licensed issuance, full reserves, audits, and AML compliance for all e-money tokens. Tether chose not to comply, so many EU exchanges delisted USDT by early 2025.

But compliance isn’t just paperwork. MiCA enforcement allowed custody and transfers, but public trading was banned in the EU—even on major platforms.

New regulations bring upside and downside. They could stabilize the ecosystem by forcing transparency and stronger reserves. But regulation could also limit USDT access, leading to liquidity fragmentation or shifts to more compliant coins.

Technical and Systemic Risks

USDT carries inherent technical and systemic risks despite its utility.

Freezing and centralization risk
USDT is centralized. Tether controls minting and can freeze assets flagged for illicit use. They froze over $126 million in 2024 and recent freezes totalled more than $40 million just this month. But the freeze process isn’t instant—AMLBot found that a delay between the freeze command and execution has allowed $78 million in illicit funds to slip free.

Depegging in volatile markets
Stablecoins can depeg during stress. USDT has experienced minor detachments during major market events like the FTX collapse. And systemic liquidity crunches could cause larger, sudden divergences in price.

Smart contract vulnerabilities
USDT is issued on multiple blockchains (Ethereum, Tron, Solana, etc.). Every platform adds its own technical risk—bugs, exploits, or blockchain congestion could delay redemptions or transfers. And smart contract updates or forks may introduce unintended behavior.

Systemic exposure
USDT’s massive circulation (over $100 billion market cap) makes it a backbone of crypto liquidity . A sudden confidence crisis or regulatory ban could destabilize the broader crypto ecosystem. Major holders and exchanges could see liquidity dry up fast—and USDT is the plumbing that connects them.

Is USDT Safe to Hold Long Term? Expert Views & Community Sentiment

Expert opinions on USDT are mixed—but lean toward cautious use. Analysts note its crucial role in crypto liquidity. But they also point out concerns over regulation and transparency.

“Tether’s regulatory and transparency issues remain a key risk factor for long‑term holders.”

Financial Times highlights stablecoin growth in mainstream finance. It names USDT as an efficient tool—but warns of low regulation and illicit use .

A Reddit user summarized USDC’s stronger standing, implicitly criticizing USDT:

“The only actual long term risk of USDC is if they are lying about their reserves… If that’s true, there is basically no risk.”

This implies USDT’s transparency remains inferior.

Arcane’s analyst Vetle Lunde warns about USDT’s depeg risk under stress events:

“Large deviations in the USDT price from the $1 peg are mostly affiliated with periods of extreme market stress… We do not view this as a likely event.” 

This suggests that a major USDT failure is unlikely—but not impossible during a crisis.

Conclusion: Is USDT Safe for the Long Haul?

USDT can be a reliable tool—but long‑term trust isn’t guaranteed.

It powers fast trading and global money movement thanks to its huge liquidity and diverse blockchain support. And Tether’s growing holdings in U.S. Treasuries show more financial maturity.

But transparency gaps remain. Audits are still pending, and regulators are tightening rules worldwide—no guarantees that USDT will always meet them.

Experts recommend cautious use: ideal for short‑term trading or payments. But for long-term storage, stablecoins with stronger audit records—like USDC—offer greater peace of mind.
