Delphi Digital has highlighted potential vulnerabilities in stablecoin systems, emphasizing that Tether and Circle are not infallible. According to Foresight News, the firm noted that despite being backed 1:1 by short-term government bonds and cash equivalents, these systems are not immune to potential runs. The de-pegging incident of USDC during the collapse of Silicon Valley Bank (SVB) in early 2023 demonstrated such risks. Although USDC was fully reserved, some reserves became temporarily inaccessible when SVB failed, indicating that risks have merely shifted upwards.
In traditional banking, payment risks are typically distributed across various institutions. However, in the stablecoin ecosystem, while payment channels may be deterministic and automated, settlement risks that were previously dispersed among participants are now concentrated at the issuer level. This shift has not eliminated risk but transformed it into a vertically dependent structure, raising concerns about issuer concentration.
