European Central Bank President Christine Lagarde warned that large stablecoins such as Tether (USDT) and USDC, which dominate a $310 billion market, present significant risks to financial stability and could transmit stress to underlying asset markets during turmoil. Speaking at the Bank of Spain's LatAm Economic Forum in Madrid, Lagarde argued against the need for privately-issued euro-pegged stablecoins, stating that the technological benefits can be replicated by central bank infrastructure while stablecoins introduce unacceptable monetary risks. Lagarde referenced the March 2023 collapse of Silicon Valley Bank, when Circle's USDC briefly de-pegged after disclosing $3.3 billion in reserves were held at the bank, as an example of how stablecoin dynamics can trigger feedback loops between redemptions and asset markets. She noted that 90% of the stablecoin market is controlled by just two issuers (Tether and Circle) and that circulation has grown from $10 billion to $310 billion in six years, underscoring the potential for systemic risk. For wallet and key holders, Lagarde's remarks highlight ongoing regulatory scrutiny that could affect stablecoin accessibility and liquidity in Europe. The ECB's push for a digital euro by 2029 may lead to new compliance requirements for stablecoin transactions, potentially impacting users who rely on USDT or USDC for trading or payments. Additionally, the risk of de-pegging events underscores the importance of diversifying holdings and being aware of reserve transparency.
