A Review of the 2023 USDC Depeg Event
In March 2023, USDC, the world's second-largest USD stablecoin, experienced a brief but severe depeg event, drawing widespread attention across the cryptocurrency market. The panic originated from Circle, USDC's issuer, disclosing that a portion of its cash reserves (approximately $3.3 billion) was held at Silicon Valley Bank (SVB), which had just collapsed. Affected by this news, the price of USDC rapidly fell within a day, hitting a low of $0.87 and even dropping to $0.74 on some trading platforms. As other stablecoins, including DAI and FRAX, also held significant amounts of USDC as collateral, their prices were also impacted, experiencing temporary declines.
Subsequently, after the U.S. Federal Reserve announced measures to protect depositors of collapsed banks, market sentiment stabilized, and the price of USDC recovered its peg to the U.S. dollar within a few days. Circle also quickly adjusted its reserve strategy to mitigate potential concentration risks in the future.
Evolution and Recent Adjustments of Binance's Stablecoin Strategy
Following the USDC depeg event, Binance, a leading global cryptocurrency exchange, made a series of adjustments to its stablecoin strategy to adapt to market changes and the regulatory environment.
- BUSD's Exit: Binance officially ceased support for its branded stablecoin BUSD on September 1, 2023, after the New York Department of Financial Services ordered Paxos to stop minting new BUSD tokens in February 2023.
- Enhanced Support for TUSD and USDT: To fill the void left by BUSD and address market demand for stablecoin diversity, Binance increased its support for TUSD and USDT. TUSD's market share significantly grew after Binance set its Bitcoin (BTC) to TUSD trading pair to zero fees.
- Dynamic Adjustments to USDC Trading Pairs: Binance added new USDC spot trading pairs in December 2023 and January 2024. However, in August 2026 (this month), Binance announced it would delist eight USDC-denominated isolated margin trading pairs and suspend BEP20 token deposits and withdrawals for wallet maintenance, indicating that Binance is continuously optimizing its stablecoin product structure on the platform.
- TUSD Trading Pair Adjustments: In April 2024, Binance also removed some TUSD spot trading pairs.
- USDT Restrictions in the European Economic Area: Notably, starting March 31, 2025, Binance has removed all USDT spot trading pairs and other stablecoin trading pairs that do not comply with MiCA regulations for users in the European Economic Area (EEA), but still allows USDT deposits and withdrawals.
Changes in the Stablecoin Market Landscape: USDT's Dominance Solidified
The USDC depeg event had a profound impact on the stablecoin market landscape. During the crisis, USDT (Tether), the largest stablecoin by market capitalization, saw significant growth in its market share and market cap, further solidifying its dominant position in the stablecoin market. As of August 2024, USDT's market cap is approximately $117 billion. In contrast, USDC's market cap, which was about $40 billion before the depeg in March 2023, once dropped to $32 billion in April 2023, and is approximately $34 billion as of August 2024.
TUSD's market cap was about $755 million at the end of 2022, increased to $2.4 billion by May 2023, but has since fallen back to about $493 million in August 2026. This reflects the fierce competition in the stablecoin market and its significant susceptibility to platform strategies and the regulatory environment.
Stablecoin Transparency and Regulatory Challenges
The USDC depeg event and subsequent market changes have once again highlighted the importance of stablecoin reserve transparency. Circle and TrueUSD, among other issuers, emphasize real-time on-chain attestations by independent third-party institutions to ensure their USD reserves are 1:1 backed by circulating tokens. Simultaneously, global regulatory frameworks such as the EU MiCA regulation are gradually being refined, pushing stablecoin issuers to meet higher transparency standards in terms of reserves and disclosures to protect investors and maintain financial stability.
