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 ...

The global saving glut and the fall in U.S. real interest rates: A 15-year retrospective
The authors revisit Ben Bernanke’s global saving glut (GSG) hypothesis from 2005—which links low long-term real interest rates in the United States to excess saving in a number of non-Western countries, including, but not limited to, China. Using an analytical framework and empirical data, they find that the ability of the GSG hypothesis to explain the fall in long-term real rates between 2002 and 2006 is likely much greater than its ability to account for the further fall in these rates from the Great Recession onward.

Liquidity traps, capital flows
Motivated by debates surrounding international capital flows during the Great Recession, we conduct a positive and normative analysis of capital flows when a region of the global economy experiences a liquidity trap. Capital flows reduce inefficient output fluctuations in this region by inducing exchange rate movements that reallocate expenditure toward the goods it produces. Restricting capital mobility hampers such an adjustment. From a global perspective, constrained efficiency entails subsidizing capital flows to address an aggregate demand externality associated with exchange rate ...

Bad Investments and Missed Opportunities? Postwar Capital Flows to Asia and Latin America
Since 1950, the economies of East Asia grew rapidly but received little international capital, while Latin America received considerable international capital even as their economies stagnated. The literature typically explains the failure of capital to flow to high growth regions as resulting from international capital market imperfections. This paper proposes a broader thesis that country-specific distortions, such as domestic labor and capital market distortions, also impact capital flows. We develop a DSGE model of Asia, Latin America, and the Rest of the World that features an ...

International capital flow pressures
This paper presents a new measure of capital flow pressures in the form of a recast exchange market pressure index. The measure captures pressures that materialize in actual international capital flows as well as pressures that result in exchange rate adjustments. The formulation is theory-based, relying on balance of payments equilibrium conditions and international asset portfolio considerations. Based on the modified exchange market pressure index, the paper also proposes a global risk response index, which reflects the country-specific sensitivity of capital flow pressures to measures of ...

The Global Financial Cycle and Capital Flows During the COVID-19 Pandemic
We estimate the heterogeneous effect of the global financial cycle on exchange rates and cross-border capital flows during the COVID-19 pandemic, using weekly exchange rate and portfolio flow data for a panel of 48 advanced and emerging market economies. We begin by estimating the global financial cycle at a weekly frequency with data through 2021 and observe the two standard deviation fall in our global financial cycle index over a period of four weeks in March 2020. We then estimate the country-specific sensitivities of exchange rates and capital flows to fluctuations in the global ...

A Theory of Capital Flow Retrenchment
The empirical literature shows that gross capital inflows and outflows both decline following a negative global shock. However, to generate a positive co-movement between gross inflows and outflows, the theoretical literature relies on asymmetric shocks across countries. We present a model where there is heterogeneity across investors within countries, but there are no asymmetries across countries. We show that a negative global shock (rise in global risk-aversion) generates an identical drop in gross inflows and outflows. The within-country heterogeneity relates to the willingness of ...

The Global (Mis)Allocation of Capital
The allocative efficiency of capital flows is one of the oldest and most contentious questions. We answer it by matching cross-border securities holdings reported in the US external statistics from 1995 to 2022 with the corresponding firm-level measures of allocative efficiency. We find that US investors tilt their international equity investment toward firms with high MRPK and markups, thereby fostering their potential for growth. Foreign investors tilt their holdings toward US firms with high productivity and intangible capital. A horse race shows that productivity is the best predictor of ...

A Theory of Net Capital Flows over the Global Financial Cycle
We develop a theory to account for changes in net capital flows of safe and risky assets over the global financial cycle. We show empirically that countries that have a net debt of safe assets experience a rise in net outflows of safe assets (reduced accumulation of safe debt) during a downturn in the global financial cycle. This is accomplished through a rise in total net outflows and a drop in net outflows of risky assets. We develop a multi-country portfolio choice model that can account for these facts. The theory relies on cross-country heterogeneity in the share of an investor's ...
