Capital Flows and the Risk-Taking Channel of Monetary Policy

This paper examines the relationship between low interests maintained by advanced economy central banks and credit booms in emerging economies. In a model with crossborder banking, low funding rates increase credit supply, but the initial shock is amplified through the "risk-taking channel" of monetary policy where greater risk-taking interacts with dampened measured risks that are driven by currency appreciation to create a feedback loop. In an empirical investigation using VAR analysis, we find that expectations of lower short-term rates dampen measured risks and stimulate cross-border banking sector capital flows.
