The short answer
USDY scores higher on safety (88 vs 88), driven mainly by collateral quality and disclosure. USDC has deeper tracked liquidity ($4.62B), which is what determines whether you can exit at size. USDC currently earns up to 25.83% — 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.

Has USDY or USDC ever depegged?
+
USDY: no material depeg recorded in our incident set. USDC: worst recorded deviation −12.0%. 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, USDY or USDC?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDC shows deeper on-chain liquidity at $4.62B versus $2.16B. Combine that with the redemption channel — USDY: gated; USDC: direct — and size trades against the primary window rather than the order book where possible.
Can I earn yield on USDY or USDC?
+
USDC currently shows the higher rate at 25.83% via forgeyields · Starknet, against 3.55% via ondo-yield-assets · Ethereum for USDY. 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 USDY and USDC?
+
Both are deployed on 11 shared networks, including Ethereum, Stellar, Sei, Solana, Mantle, Sui. USDY spans 11 chains in total and USDC spans 121. 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 USDY to USDC?
+
Budget three components: the current price spread of roughly 1433.1 bps, swap or venue fees, and slippage against available depth ($2.16B for USDY, $4.62B for USDC). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is USDY or USDC regulated?
+
USDY is issued from BVI with monthly; USDC is issued from United States (NYDFS / MiCA) with monthly. 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.
