Speculative Attacks are a coordination game with multiple equilibria if the payoff function is common knowledge. With private information there is a unique equilibrium. This raises the question whether public information may be destabilizing by allowing for self-fulfilling beliefs. We present an experiment that imitates a speculative attacks model and compare sessions with public and private information. Our evidence suggests that public information does not lead to self-fulfilling beliefs. Predictability of attacks is even higher with public than with private information. Prior probability of attacks is also higher with public information. With public information subjects coordinate on equilibria somewhere between payoff dominant and risk dominant equilibrium. Reactions to parameter changes go into the directions predicted by risk dominance.
