Abstract

We construct a novel and unique data set of transaction-level data of eight major stablecoins to comprehensively examine trading activities during stress events within the stablecoin ecosystem. Our study encompasses a sample period that spans four significant crisis events, including the Terra-Luna collapse, the FTX failure, the Binance USD issuance halt, and the Silicon Valley Bank failure which impacted the stablecoin USDC. Our analysis reveals some common patterns across these crises. Although the Terra Luna and FTX shocks affected a broad range of stablecoins and activities, we find that contrary to anecdotal beliefs, these crypto shocks did not result in a systemic flight to safety from stablecoin assets to fiat currencies. Rather, we observe substitution effects between stablecoins, wherein investors pivot from riskier stablecoins to safer alternatives with similar functionalities. We identify a redistribution of stablecoin usage, characterized by outflows from riskier activities towards more secure channels. Our empirical study reveals that the Binance and the Silicon Valley bank banking stress events primarily affected the particular stablecoin involved (i.e. BUSD and USDC, respectively) with rival stablecoins gaining market share.
