Key Highlights
- Joseph, ex-Citi Crypto Lead, says Hayes misread Tether’s reserves and ignored billions in corporate equity and annual profits.
- Tether CEO Paolo Ardoino cites $30B in group equity and strong Treasury income, dismissing insolvency concerns as “FUD.”
- Hayes warns Tether faces rate-cut risk and portfolio volatility, reigniting debate over transparency and stablecoin stability.
A public exchange on X between former Citi Crypto Research Lead Joseph and BitMEX Co-Founder Arthur Hayes has reignited debate over the financial stability and transparency of Tether, the world’s largest stablecoin issuer.
Hayes suggested that recent attestation data show Tether may be taking on higher risk as interest-rate conditions shift — a claim that Tether executives and former analysts quickly dismissed.
Hayes warns of interest-rate pressure, portfolio volatility
In a November 30 post, Hayes argued that Tether’s growing exposure to Bitcoin and gold indicates an underlying bet that U.S. Federal Reserve rate cuts are coming. Lower yields, he said, would reduce Tether’s substantial interest income from its U.S. Treasury holdings.
He also cautioned that market volatility could undermine the company’s equity cushion: “A roughly 30% decline in the gold + $BTC position would wipe out their equity, and then USDT would be in theory insolvent.”
Hayes predicted that major USDT holders will demand greater real-time transparency and added that mainstream media coverage could accelerate pressure on Tether in the coming months.
Former Citi analyst: Hayes “missed a few key points”
Responding to Hayes, Joseph — who said he spent “100s of hours writing research on tether for Citi” — pushed back on the insolvency narrative, arguing that Hayes misunderstood the nature of Tether’s disclosures and vastly underestimated its underlying corporate strength.
Tether’s public reserves do not reflect its full balance sheet
Joseph emphasized that Tether’s published reserve breakdown is not the same as its full corporate asset base: “Their disclosed assets =/ all corporate assets.”
He explained that Tether maintains a separate equity balance sheet that includes equity stakes, mining operations, corporate reserves, and potentially more Bitcoin. These are not part of the public attestation because they sit outside the strict “matching” model used to show stablecoin backing.
“Highly profitable” with billions in annual income
According to Joseph, the company’s profitability alone makes insolvency unlikely. With an estimated $120 billion invested in U.S. Treasuries yielding around 4% since 2023, he estimated Tether generates roughly $10 billion annually in liquid profit, with a lean workforce of around 150 employees.
Joseph argued this makes Tether “one of the most efficient cash generating businesses in the world.”
He added that the firm’s equity could be worth “$50–100bn,” and although Tether has reportedly explored a raise valuing the firm at $500 billion, he acknowledged such a valuation is likely unrealistic but still signals the scale of its asset base.
Better collateralized than banks
Joseph also compared Tether’s reserves to U.S. banks, which typically hold only 5–15% of deposits in liquid assets.
While acknowledging that Tether lacks a central-bank backstop, he argued its collateralization practices are stronger and far more conservative than traditional fractional-reserve institutions.
His conclusion: Tether is nowhere near insolvency.
Tether CEO Paolo Ardoino also responds: “FUD” and missing math
Tether CEO Paolo Ardoino entered the discussion as well, pointing to the company’s Q3 2025 attestation, which included a clearer statement on the company’s total equity position:
“Tether will continue to maintain a multi-billion-dollar excess reserve buffer and an overall proprietary Group equity approaching $30 billion.”
Ardoino said that at the end of Q3, Tether held approximately $7 billion in excess equity backing stablecoins, plus around $23 billion in retained earnings within the broader Tether Group.
He summarized the company’s balance sheet as:
- Tether Group Total Assets: ~$215B
- Stablecoin Liabilities: ~$184.5B
He argued that several critics — including S&P — made the same mistake by ignoring the firm’s broader equity and its “~500M in monthly base profits generated by U.S Treasury yields alone.”
Ardoino attributed some of the criticism to rival incentives rather than genuine analysis: “Some influencers are either bad at math or have the incentive to push our competitors.”
He closed his post with a nod to iconic heavy metal band Metallica: “Forever trusting who we are / No, nothing else matters.”
A familiar battle over transparency
The renewed debate underscores a recurring tension around Tether: its unmatched profitability and market dominance on one side, and ongoing questions about transparency, portfolio risk, and regulatory oversight on the other.
With more than $184 billion in stablecoins outstanding and a widening mix of investments, the company remains a focal point in crypto’s broader discussions about systemic risk and resilience.
Whether the market agrees with Hayes’ warning or Joseph’s confidence may ultimately depend on how interest rates move and how much visibility Tether is willing to provide into the parts of its balance sheet it does not yet disclose publicly.
