We develop a model of financial intermediation wherein bank managers "reach for yield" - by overinvesting in risky assets and underinvesting in safer assets - provided they do not face much cost from liquidity shortfalls. The managers follow a pecking order in which their first preference is to invest in risky assets; their second preference is to hoard liquid assets; and their last preference is to invest in safer assets. This behavior is conducive to the formation of bubbles and "negative" bubbles in the market for risky and safer assets, respectively. Monetary loosening, by reducing the cost of liquidity shortfalls, induces further reach for yield and amplifies the bubbles.
