Tether, the company behind the world’s leading stablecoin USDT, is under increasing examination regarding its approach to managing reserves. Experts caution that a sharp decline in the prices of Bitcoin and gold—two assets now heavily featured in Tether’s portfolio—could put the stablecoin’s financial health at risk. This scrutiny follows a recent downgrade by S&P Global Ratings, which pointed to a growing share of high-risk assets backing USDT. Industry voices, including BitMEX co-founder Arthur Hayes, have also raised alarms about Tether’s exposure to volatile markets. Despite these warnings, CEO Paolo Ardoino maintains that Tether is “overcapitalized” and holds no “toxic” assets, according to recent statements. Nonetheless, the ongoing debate reflects broader anxiety about the resilience of stablecoins as economic conditions shift.
In anticipation of potential interest rate cuts by the Federal Reserve—which would lower yields on traditional assets like Treasury bills—Tether has increased its holdings in Bitcoin and gold. The company’s latest disclosures reveal that Bitcoin now constitutes 5.6% of USDT’s reserves, surpassing its 3.9% overcollateralization buffer. Hayes argues that while this move may prepare Tether for a lower-rate environment, it also exposes the company to significant risk: a major drop in Bitcoin or gold prices could wipe out Tether’s equity cushion and threaten its solvency. He estimates that a 30% decline in these assets could have severe consequences for the stablecoin’s backing.
The inherent instability of cryptocurrency and gold markets amplifies these risks. Historical trends show that Bitcoin has suffered losses exceeding 50% during previous downturns, casting doubt on Tether’s ability to withstand similar shocks. S&P has acknowledged that most of USDT’s reserves remain in liquid assets, but the agency has also called for greater clarity regarding the composition and management of these reserves. With an estimated $10–15 billion invested in gold and Bitcoin, Tether’s hedging portfolio could come under strain if market conditions worsen—especially given USDT’s commanding 60% share of the stablecoin sector.
Amid these concerns, market participants and trading platforms are urging Tether to provide more transparency. Hayes has suggested that major stakeholders may soon insist on real-time balance sheet updates to better assess the company’s solvency. While Ardoino has characterized the criticism as stemming from traditional finance’s resistance to innovation, Tether’s reliance on riskier assets has drawn parallels to previous crises in the crypto industry, where lack of transparency led to loss of confidence and market turmoil.
This situation underscores the challenge of balancing protection against fiat currency devaluation with the need to maintain stablecoin reliability. As Tether navigates an unpredictable economic environment, both regulators and investors are expected to scrutinize its risk management more closely. Any further decline in the value of its gold and Bitcoin reserves could threaten USDT’s 1:1 dollar peg and have far-reaching effects across the cryptocurrency ecosystem, where stablecoins play a crucial role in supporting daily trading volumes exceeding $40 billion.
