DP18231 Global Liquidity: Drivers, Volatility and Toolkits

Global liquidity refers to the volumes of financial flows – largely intermediated through global banks and non-bank financial institutions – that can move at relatively high frequencies across borders. The amplitude of responses to global conditions like risk sentiment, discussed in the context of the global financial cycle, depends on the characteristics and vulnerabilities of the institutions providing funding flows. Evidence from across empirical approaches and using
granular data provides policy-relevant lessons. International spillovers of monetary policy and risk sentiment through global liquidity evolve in response to regulation, the characteristics of financial institutions, and actions of official institutions around liquidity provision. Strong
prudential policies in the home countries of global banks and official facilities reduce funding strains during stress events. Country-specific policy challenges, summarized by the monetary and financial trilemmas, are partially alleviated. However, risk migration across types of financial intermediaries underscores the importance of advancing regulatory agendas related to non-bank financial institutions.
