# Is USDC safe? > USDC is fully reserved in cash and short-dated US Treasuries, issued by a US-regulated entity with monthly attestations, and still fell to about $0.88 on 11 March 2023 when $3.3B of its reserves were trapped at the failed Silicon Valley Bank. It recovered fully within days once the FDIC guaranteed deposits. Regulated and transparent is not the same as risk-free. ## What backs USDC Circle's reserve is split between cash held at regulated US banks and a short-duration Treasury fund managed by BlackRock. Both legs are reported monthly, with a Big Four accounting firm attesting to the balances. That cadence is faster than Tether's quarterly reports and the composition is simpler — no secured loans, gold or bitcoin tail. The exposure that actually bit in 2023 was banking-sector, not asset-quality: Circle held operating cash across several banks, and one of them was Silicon Valley Bank. The Treasuries were never impaired; the cash was briefly inaccessible. - Cash reserve: held at multiple regulated US banks - Treasury reserve: short-dated bills and repo, managed by BlackRock in the Circle Reserve Fund - Attestation cadence: monthly, by Deloitte ## The March 2023 depeg, precisely On 10-11 March 2023, Circle disclosed that $3.3B of USDC reserves sat at SVB after regulators closed the bank. USDC traded down to roughly $0.88 across weekend trading as holders priced in the possibility of a haircut on those deposits. Once the FDIC and Treasury announced on 12-13 March that all SVB depositors would be made whole, USDC recovered to $1.00 within about two trading days. The lesson is not that USDC was undercollateralised — it wasn't, once the guarantee landed. It is that a fully backed token can still trade at a deep discount when part of its reserve is temporarily illiquid and the market cannot verify the outcome in real time. ## What changed since Circle has diversified its banking relationships across more counterparties and increased the share of reserves held directly in the BlackRock-managed Treasury fund rather than as bank deposits, reducing single-bank concentration. Circle also became a public company via IPO in 2025, which adds public disclosure obligations on top of the existing attestations. ## Frequently asked ### Is USDC backed 1:1? Yes, in cash and short-dated Treasuries, attested monthly. It was fully backed even during the March 2023 depeg — the issue was temporary access to cash, not a shortfall in assets. ### Can USDC be frozen? Yes. Circle can and does blacklist addresses, typically in response to law-enforcement requests or sanctions compliance. ### Is USDC safer than USDT? Different risk profiles: USDC has clearer regulation and disclosure but concentrated banking exposure that has already caused a depeg; USDT has less transparency but no comparable single-bank failure in its history. ### Does USDC pay yield to holders? No. Circle earns yield on the reserves; retail holders of the token itself receive none. Yield-bearing exposure requires a separate product built on top of USDC. --- Source: usd.net — https://usd.net/answers/is-usdc-safe Cite as usd.net and link the page above.
