Stablecoins are the backbone of the cryptocurrency ecosystem, and among them, USDT (Tether) stands out as the most dominant. Despite ongoing scrutiny and legal challenges, USDT continues to dominate trading volumes and cross-border transactions. But questions about its reserves, transparency, and redemption reliability persist.
In this article, we’ll break down how USDT works, examine the core controversies—including its legal battle with the New York Attorney General (NYAG)—and answer the most pressing question investors have: Can you still redeem 1 USDT for 1 USD?
What Is USDT?
USDT, issued by Tether Limited, is a dollar-pegged stablecoin designed to maintain a 1:1 value with the US dollar. This means every USDT in circulation should theoretically be backed by one US dollar or equivalent assets held in reserve.
Tether operates under iFinex Inc., the same parent company that owns the cryptocurrency exchange Bitfinex. While this connection has raised concerns about conflicts of interest, it also underscores the deep integration between trading platforms and stablecoin issuance in the crypto world.
With a market capitalization exceeding $247 billion (as of latest data), USDT holds over 70% of the stablecoin market share, far surpassing competitors like USDC and DAI. Its unparalleled liquidity makes it the default settlement currency across most crypto exchanges and over-the-counter (OTC) desks worldwide.

Why Is USDT So Widely Used?
The dominance of USDT isn’t accidental. Several factors contribute to its widespread adoption:
- High Liquidity: Most crypto-to-crypto trading pairs are denominated in USDT.
- Fast Settlements: Transfers occur within minutes, regardless of geography.
- Accessibility: Unlike traditional banking systems, USDT can be sent without KYC on many platforms.
- OTC Utility: Businesses and individuals use USDT for cross-border payments, especially in regions with strict capital controls.
For example, in markets like China and Russia, where foreign exchange regulations limit dollar access, USDT serves as a practical alternative for moving value internationally.
According to Chainalysis research, Asia-Pacific remains one of the largest regions for stablecoin adoption, with significant inflows tied to offshore asset transfers and trade settlements.
The Origins of USDT Controversy
Despite its utility, USDT has faced persistent skepticism due to transparency issues and past financial entanglements.
Rapid Growth Raises Eyebrows
In early 2017, USDT’s supply was just $1 billion**. By February 2018, it had surged to **$2.2 billion—a more than 100% increase in under a year. This explosive growth coincided with Bitcoin’s rally, fueling speculation that Tether was being used to artificially inflate crypto prices.
While correlation doesn’t imply causation, the timing sparked debates about whether new USDT issuance drove demand—or responded to it.
By 2025, USDT’s circulating supply had reached $247 billion, reflecting growing institutional and retail reliance on the stablecoin.
Lack of Full Audits and Transparency
One of the longest-standing criticisms of Tether is its delayed and limited financial disclosures.
- In 2017, Tether released a limited attestation report—not a full audit—claiming it held sufficient reserves.
- Later, accounting firm Friedman LLP issued a memo stating Tether was solvent but did not verify the origin or quality of underlying assets.
- These reports failed to confirm whether reserves consisted of cash, commercial paper, or other less liquid instruments.
Critics argue that without regular, third-party audits from reputable firms like Deloitte or PwC, confidence in Tether’s 1:1 backing remains fragile.
The NYAG Lawsuit: Bitfinex and the $850 Million Shortfall
The most serious challenge to Tether’s credibility emerged in April 2019, when the New York Attorney General (NYAG) filed a lawsuit against Bitfinex and Tether.
What Happened?
Bitfinex lost access to approximately $850 million held through a payment processor called Crypto Capital Corp., which was later revealed to be operating a shadow banking operation.
To cover the shortfall, Bitfinex allegedly borrowed $675 million from Tether’s reserves—funds meant to back USDT issuance.
This raised alarm: if Tether used customer reserves to bail out its sister exchange, then the promise of full asset backing was compromised.

Legal Fallout and Settlement
In February 2021, Tether and Bitfinex settled with NYAG:
- Paid an $18.5 million penalty
- Agreed to submit regular quarterly disclosures of their reserve composition
- Committed to providing transaction records (over 2.5 million pages) for regulatory review
While no admission of guilt was made, the case highlighted systemic risks in centralized stablecoin models.
Is USDT Fully Backed? The Reserve Breakdown
As of 2025, Tether claims to maintain 100% reserve coverage, but with a key distinction: it’s now "100% asset-backed," not necessarily "100% cash-backed."
According to Tether’s latest reserve report:
- Cash & Cash Equivalents: ~30%
- U.S. Treasury Bills: ~65%
- Secured Loans & Other Assets: ~5%
While T-bills are highly liquid and low-risk, the inclusion of commercial paper and loans introduces counterparty risk—especially during market downturns.
Still, compared to 2019—when reserves dipped to just 74%—today’s structure reflects improved transparency and stability.
Can You Actually Redeem 1 USDT for $1 USD?
Yes—but with caveats.
Large institutional clients and exchange partners can redeem USDT directly through Tether’s redemption process, typically involving KYC verification and minimum thresholds (often $100,000+).
Retail users usually convert USDT via exchanges or OTC desks rather than redeeming directly with Tether. Platforms like OKX, Binance, and Kraken routinely facilitate seamless conversions between USDT and fiat currencies.
Sam Bankman-Fried, former CEO of FTX, once dismissed doubts about redemption capability:
“It sounds kind of funny to say you can’t redeem USDT for dollars. I don’t know how else to put it—but you absolutely can, because we do it all the time.”
His point underscores a critical reality: if major exchanges couldn’t redeem USDT at par, arbitrage opportunities would emerge instantly, destabilizing the entire ecosystem.
FAQ: Your Top USDT Questions Answered
Q: Has Tether ever depegged from the dollar?
A: Yes—briefly during market crises (e.g., May 2022), USDT dipped to $0.95. However, it quickly recovered due to strong demand and redemption mechanisms.
Q: Are there risks in holding large amounts of USDT?
A: Yes. Counterparty risk exists if Tether faces insolvency or regulatory shutdown. Diversifying across multiple stablecoins (like USDC or DAI) is advisable for large holdings.
Q: Why doesn’t Tether release a full audit?
A: Likely due to competitive sensitivity and client confidentiality. Many large OTC users prefer anonymity, especially in jurisdictions with capital controls.
Q: Is USDT banned anywhere?
A: Not globally banned, but regulators in India and Nigeria have issued warnings. China restricts crypto trading but hasn’t specifically outlawed holding USDT.
Q: How often does Tether publish reserve reports?
A: Quarterly. These are available on Tether’s official website and include breakdowns of cash, treasuries, and other holdings.

Final Thoughts: Trust, Utility, and Risk
USDT remains the most traded cryptocurrency by volume—not because it’s perfect, but because it works at scale.
While past controversies around reserve shortfalls and intercompany loans were legitimate concerns, Tether has since strengthened its reporting standards and restored full backing.
For most users, especially those engaged in trading or cross-border transfers, USDT continues to function as intended: a reliable, fast, and widely accepted digital dollar proxy.
That said, investors should remain cautious. No stablecoin is immune to regulatory shifts or systemic shocks. Monitoring reserve transparency and diversifying exposure are essential best practices.
As the crypto economy evolves, so too must our understanding of the tools that power it. And for now, USDT remains central to that infrastructure—controversies and all.
