This article analyzes the dynamic coordination problem among creditors of a firm with a time-varying fundamental and a staggered debt structure. In deciding whether to roll over his debt, each maturing creditor is concerned about the rollover decisions of other creditors whose debt matures during his next contract period. We derive a unique threshold equilibrium and characterize the roles of fundamental volatility, credit lines, and debt maturity in driving runs. In particular, we show that when fundamental volatility is sufficiently high, commonly used measures such as temporarily keeping the firm alive under runs and increasing debt maturity can exacerbate rather than mitigate runs.
