The USDC price in reais with the time it was taken, a two-way converter, and how its reserves differ from Tether's — including the weekend in 2023 when it broke the dollar anyway.
USD Coin Price Today (USDC to BRL): R$ 5,1500, -0,12%.
USDC is the other dollar stablecoin, issued since 2018 by Circle, an American company that listed on the New York Stock Exchange in June 2025. It does what Tether does — hold one dollar of value — but the backing is not built the same way. USDC's reserves are cash at regulated US banks plus the Circle Reserve Fund, a government money market fund managed by BlackRock and registered with the SEC, whose holdings are published. Circle releases monthly reserve reports attested by a large accounting firm. No gold, no bitcoin, no lending book. That is the trade: less liquidity than USDT, considerably more paperwork.
And it broke anyway. On 10 March 2023 Silicon Valley Bank failed holding 3.3 billion dollars of USDC reserves. Redemptions could not clear over a weekend, and USDC traded near 0.87 dollars on the Saturday, climbing back to a dollar within days once US regulators guaranteed the bank's deposits. That is the most useful thing to know about stablecoins in general, and why this page will not call any of them safe. The token did not slip because it was unbacked. It slipped because the backing sat in a bank, and banks fail. Full reserves reported monthly do not remove the risk; they tell you where it is.
The number at the top is two things multiplied: the dollar in reais, and whatever premium or discount the Brazilian crypto market is putting on a dollar today. It is a market price, not the commercial rate, and your exchange adds its spread and withdrawal fee on top. In Brazil, USDC is the thinner of the two markets: USDT is the default, the books are smaller and a large order moves the price further, which is why the two do not always print the same number in reais. Two practical notes. Sending USDC to an address on a network that does not support it loses it. And holding it pays you nothing: the interest on those Treasury reserves is the issuer's revenue, not yours.
From CoinGecko, which aggregates USDC trades across exchanges. A job on our server stores it every 30 minutes and prints it here with the exact date and time of the quote.

Because this is an aggregated reference and your exchange is quoting an offer: it buys below the market, sells above it, and charges trading and withdrawal fees. USDC has less liquidity in Brazil than USDT, so the spread is usually wider and a large order moves it more.
No, and it has already proved it. In March 2023 the failure of Silicon Valley Bank, which held 3.3 billion dollars of the reserves, sent USDC to around 0.87 dollars over a weekend. Parity is an issuer's commitment supported by reserves, not a guarantee, and the reserves themselves sit somewhere that can fail.
The reserves and the liquidity. USDC is backed by cash and a registered government money market fund, reported monthly; Tether publishes quarterly attestations over a portfolio that also includes gold, bitcoin and secured loans. In exchange, USDT is far more widely traded, especially in Brazil. Neither fact is a recommendation, and both tokens have left the peg.
Not from the token itself. The interest earned on the reserves belongs to the issuer, so holding USDC is lending a dollar at zero per cent in return for being able to send it anywhere in minutes. Platforms offering a yield on a stablecoin balance are lending it on, which adds their credit risk to the token's.
