The macroeconomics of liquidity in financial intermediation
In financial crises, the premium on liquid assets such as US Treasuries increases alongside credit spreads. This paper explains the link between the liquidity premium and spreads. We present a theory of endogenous bank fragility arising from a coordination friction among bank creditors. The theory’s implications reduce to a single constraint on banks, which is embedded in a quantitative macroeconomic model to investigate the transmission of shocks to spreads and economic activity. Shocks that reduce bank net worth exacerbate the coordination friction.
