The short answer
USDG scores higher on safety (93 vs 77), driven mainly by collateral quality and disclosure. USDT has deeper tracked liquidity ($1.96B), which is what determines whether you can exit at size. USDT currently earns up to 9.00% — remember that any rate above the T-bill yield is payment for a risk.
If both are fiat-reserve tokens, note that holding both is not diversification: they share the same short-dated Treasury and banking exposure. Genuine diversification means mixing collateral structures.

USDG vs USDT: frequently asked questions
Is USDG or USDT safer?
+
On our composite safety score USDG rates 93/100 versus 77/100 for USDT. The score weighs collateral quality (treasuries vs fiat-reserves), redemption rights, attestation quality, peg history and liquidity depth. A higher score is not a guarantee: both remain issuer-credit and smart-contract exposures, not insured bank deposits.
What is the difference between USDG and USDT?
+
Global Dollar is issued by Paxos Digital Singapore (Singapore (MAS)), backed by treasuries, with redemption terms: direct. Tether is issued by Tether (El Salvador / BVI), backed by fiat-reserves, with redemption terms: gated. Attestation coverage is "monthly" for USDG and "quarterly" for USDT.
Which has the bigger market cap, USDG or USDT?
+
USDT is larger at $183.76B in circulating supply, against $3.09B for the other. Over the last 7 days supply moved −3.15% for USDG and +0.01% for USDT.
Are USDG and USDT trading at $1.00 right now?
+
USDG trades at $1.0000 (−0.004% off peg) and USDT at $0.9999 (−0.009% off peg). The gap between the two is about 0.5 basis points, which is the cost you pay when rotating size between them before fees.
Has USDG or USDT ever depegged?
+
USDG: no material depeg recorded in our incident set. USDT: worst recorded deviation −4.8%. Past peg behaviour under stress is the single best available proxy for how a token trades in the next crisis.
Which is better for large institutional size, USDG or USDT?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDT shows deeper on-chain liquidity at $1.96B versus $789.34M. Combine that with the redemption channel — USDG: direct; USDT: gated — and size trades against the primary window rather than the order book where possible.
Can I earn yield on USDG or USDT?
+
USDT currently shows the higher rate at 9.00% via zerobase-cedefi · Ethereum, against 6.74% via kamino-lend · Solana for USDG. Neither token pays interest by holding it in a wallet: the yield comes from lending, liquidity provision or a wrapped yield-bearing version, each with its own counterparty and contract risk.
Which chains support both USDG and USDT?
+
Both are deployed on 5 shared networks, including X Layer, Solana, Ethereum, Ink, Hyperliquid L1. USDG spans 6 chains in total and USDT spans 97. Bridged supply on a chain is not the same as natively issued supply, and it usually carries the bridge's risk rather than the issuer's.
What does it cost to switch from USDG to USDT?
+
Budget three components: the current price spread of roughly 0.5 bps, swap or venue fees, and slippage against available depth ($789.34M for USDG, $1.96B for USDT). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is USDG or USDT regulated?
+
USDG is issued from Singapore (MAS) with monthly; USDT is issued from El Salvador / BVI with quarterly. Regulatory status varies by your own jurisdiction and by whether the token is offered under a specific stablecoin regime, so treat this as a starting point for diligence, not legal advice.
