Fractional Reserve Risk

Fractional reserve risk refers to the danger that a financial institution does not hold enough liquid assets to meet all withdrawal requests simultaneously. This practice involves keeping only a fraction of customer deposits in reserve while lending or investing the remainder to generate profit.

If too many users attempt to withdraw their funds at the same time, the institution may face a liquidity crisis, leading to a bank run. In the digital asset space, this risk is exacerbated by the lack of traditional deposit insurance and the high speed of automated trading.

Protocol physics often dictate that if assets are locked in smart contracts or yield-bearing instruments, they may not be immediately available for withdrawal. Managing this risk requires rigorous capital adequacy requirements and transparent solvency reporting.
