# Black Swan

A secondary risk faced by Metronome users is a 'black swan' event, where either a synth’s underlying asset or a collateral asset sees a rapid change in price. In extreme cases, the user will not be able to modify their position fast enough to avoid liquidation. This is a broader risk that affects DeFi lending and synthetic protocols as a whole.
