Risks in Tether’s $181 billion USDT reserve and regulatory gaps

Asset Volatility and Capital Buffers

Tether reported $1.04 billion in net income for the first quarter of 2026, which helped grow shareholder equity to $8.2 billion. Despite this profit, the company’s reserve composition carries market exposure. As of September 30, 2025, Tether held $181.2 billion in total reserves. While 77.23% of these assets, totaling $139.9 billion, consist of cash and cash equivalents, the remaining $41.3 billion includes volatile holdings. Tether holds $12.9 billion in gold and $9.8 billion in Bitcoin. It also maintains $14.6 billion in secured loans and $3.8 billion in other investments. Because these assets are valued at fair value, a 25% drop in these riskier holdings would wipe out the company’s $8.2 billion capital buffer. In the first quarter of 2026, USDT liabilities declined by 1.6% from $186.5 billion to $183.5 billion. You should monitor the $14.6 billion in secured loans, as Tether previously promised to reduce these to zero by the end of 2023. I find that the reliance on these non-cash assets creates a volatility profile that does not align with a stable dollar peg. Tether’s quarterly attestations, prepared by BDO, do not provide the same level of rigor as a full audit performed by a CPA firm in accordance with GAAP standards. This lack of a full audit leaves questions about the exact location of all cash deposits.

Regulatory and Compliance Divergence

The regulatory environment shifted after the US GENIUS Act passed in July 2025. This law requires companies to maintain transparency that Tether has historically avoided. Tether lacks the licenses required to operate within the US or the EU under MiCA rules. This forced Tether to launch USAT, a separate US-regulated stablecoin issued by Anchorage Digital Bank. In contrast, USDC is fully compliant with both the GENIUS Act and MiCA, making it the preferred choice for regulated financial infrastructure. This regulatory gap is large. In 2021, Tether paid $18.5 million to the New York Attorney General and $41 million to the CFTC following investigations into its reserve disclosures. Historically, Tether reserves were not fully backed for only 27.6% of the days in a 26-month period between 2016 and 2018. The US GENIUS Act requires stablecoin issuers serving US customers to hold full 1:1 reserves in cash or high-quality liquid assets, comply with anti-money laundering rules, and obtain federal licensing. Tether’s lack of MiCA authorization restricts its availability on major European exchanges like Binance and Kraken. While USDC grew 72% year-over-year to $75.3 billion, Tether’s growth is increasingly limited to non-regulated jurisdictions. Tether’s 2025 profits exceeded $10 billion, which the company uses for reinvestment in Bitcoin and other assets. The SEC and CFTC even initiated "Project Crypto" in early 2026 to harmonize federal oversight of crypto asset markets, seeking to provide clarity in the absence of congressional action.

Liquidity and Counterparty Risks

Tether’s massive position in the US Treasury market introduces systemic risks. As of early 2026, Tether’s US Treasury exposure remains between $135 billion and $138 billion. Because Tether is not a US person, it manages these holdings through Cantor Fitzgerald. This arrangement creates counterparty risk for USDT holders. If market stress triggers a mass redemption, Tether must sell its Treasury holdings at market prices to satisfy demand. Such a liquidation could cause volatility in the short-term debt market. A 10% rise in stablecoin capitalization causes a 3 to 7 basis point compression on 3-month T-bills. This effect intensifies during periods of Treasury market stress.

Tether’s dominance relies on its distribution network through the Tron blockchain, where 60% of the supply resides. USDT processed $156 billion in payments under $1,000 in 2025, mainly via Tron. While the market cap is $183.6 billion, supply contracted in early 2026. A $3.5 billion inflow into stablecoins lowers 3-month Treasury bill yields by 0.71 basis points on impact. Tether’s US Treasury exposure ranks it 17th worldwide among holders. Will the liquidity of the US Treasury market be enough to absorb a sudden, massive redemption of USDT?
