1 Risk Crypto Investors Should Watch With Tether

Tether (USDT) remains the most traded and liquid stablecoin—often moving in step with Bitcoin and serving as a go-to on‑ramp—but investors should weigh persistent transparency concerns: New York AG findings showed USDT was not fully 1:1 backed in 2017–18 and reserves were used to cover a Bitfinex shortfall, Tether uses offshore banking partners and only reports reserves quarterly. USD Coin (USDC), by contrast, offers greater disclosure—Circle went public in June 2025, is subject to SEC filings, is New York–based and reports full reserves monthly—so the choice for institutions is effectively liquidity (USDT) versus regulatory/transparency comfort (USDC). Regardless, no stablecoin is risk‑free: de‑pegging, liquidity squeezes and regulatory shifts can impair redemption values, so custody and counterparty diligence remain essential.

Analysis

Tether (USDT) remains the most traded and liquid stablecoin, frequently moving in step with Bitcoin and serving as a primary on‑ramp; the article notes USDT has significantly higher trading volume and roughly twice the market capitalization of USD Coin (USDC). Each USDT is pegged to the dollar, which supports its role as a short‑term safe haven in high‑liquidity market episodes, but liquidity advantages do not eliminate counterparty risk.

Regulatory and historical transparency issues are the key concern: New York Attorney General findings showed that in 2017–2018 Tether Limited did not maintain full 1:1 backing and diverted reserves to cover a shortfall at Bitfinex, leading to both companies being banned from doing business in New York. Tether continues to hold portions of reserves with offshore banks, including in the Bahamas, and publishes reserve information quarterly, which limits U.S. regulatory visibility relative to U.S. domiciled issuers.

Circle’s USDC presents a clearer disclosure profile—Circle went public in June 2025, is subject to SEC reporting, is New York–based, and reports full reserves monthly—making USDC the more transparent option. The practical tradeoff is transparency versus liquidity: no stablecoin is risk‑free, and de‑pegging, liquidity squeezes, or regulatory shifts can cause losses or impaired fiat redemptions.

Investors should therefore prioritize custody, counterparty due diligence, and monitoring of reserve reports and regulatory developments when allocating between USDT and USDC, aligning choice to liquidity needs and risk tolerance.

Key Decisions for Investors

• Allocate short‑term, reserve‑sensitivity exposure to USDC where possible given Circle's SEC reporting and monthly full reserve disclosures,
• Use USDT selectively for liquidity‑intensive trading but cap exposure and require strong custodial/counterparty controls because of USDT's weaker transparency despite higher volume and market cap,
• Monitor reserve reports and regulatory actions closely and be prepared to reduce or hedge positions if disclosure cadence, offshore banking arrangements, or enforcement risk increases,
• Avoid concentration in a single stablecoin; maintain redemption testing, ready fiat liquidity and contingency plans to manage potential de‑pegging or liquidity squeezes
