Global Liquidity And Drivers Of Cross Border Bank Flows

This paper provides a definition of global liquidity consistent with its meaning as the “ease of financing” in international financial markets. Using a longer time series and broader sample of countries than in previous studies, it identifies global factors driving cross-border bank flows, alongside country-specific factors. It confirms the explanatory power of US financial conditions, with flows decreasing in market volatility (VIX) and term premia, and increasing in bank leverage, growth in domestic credit and M2. A new finding is that similar variables for other systemic countries – the UK and the Euro Area – are also important, sometimes even more so, consistent with the dominant role of European banks in cross-border banking. Furthermore, recipient country characteristics are found to affect not only the level of country-specific flows, but also the cyclical impact of global liquidity, with sensitivities of flows to banks decreasing with stronger macroeconomic frameworks and better bank regulation, but less so for flows to non-financial firms.

The paper starts by presenting evidence of commonality in global financial conditions. This commonality is then related to specific drivers of global financial conditions through a range of transmission channels, including cross-border banking and portfolio flows. Empirical analysis shows a range of price and quantity factors, including measures of risk, bank leverage, and interest rates in financial centers, to drive in part these flows. Country specific policies, including exchange rate and prudential frameworks, are shown to affect the transmission of global conditions. Much remains unknown though, including how evolving structures of global funding, changing institutions, and ongoing financial innovations affect the mechanics of liquidity creation, the channels of liquidity transmission, and potential risks going forward.

This paper develops a small open economy model where global and domestic liquidity is intermediated to the corporate sector through two financial processes. Investment banks intermediate cross-border credit through interlinked debt contracts to entrepreneurs and commercial banks intermediate domestic savings to liquidity constrained final good producers. Both processes are needed to facilitate development of key production inputs. The model captures procyclical investment bank leverage dynamics, global liquidity spillovers, domestic money market pressures, and macrofinancial linkages through which shocks propagate across the two processes, affecting spreads and balance sheets, as well as the real economy through investment and working capital channels.

While global uncertainty—measured by the VIX—has proven to be a robust global “push” factor of international capital flows, there has been no systematic study assessing the role of country-specific uncertainty as a key (pull and push) factor of international capital flows. This paper tries to fill this gap in the literature by examining the effects of country-specific uncertainty shocks on cross-border banking flows using the confidential Bank for International Settlements Locational Banking Statistics data. The dyadic structure of this data allows to disentangle supply and demand factors and to better identify the effect of uncertainty shocks on cross-border banking flows. The results of this analysis suggest that: (i) uncertainty is both a push and pull factor that robustly predicts a decrease in both outflows (retrenchment) and inflows (stops); (ii) global banks rebalance their lending towards safer foreign borrowers from local borrowers when facing higher uncertainty; (iii) this rebalancing occurs only towards advanced economies (flight to quality), but not emerging market economies.

International banks greatly reduced their direct cross-border and local affiliates’ lending as the global financial crisis strained balance sheets, lowered borrower demand, and changed government policies. Using bilateral, lender-borrower countrydata and controlling for credit demand, we show that reductions largely varied in line with markets’ prior assessments of banks’ vulnerabilities, with banks’ financial statement variables and lender-borrower country characteristics playing minor roles. We find evidence that moving resources within banking groups became more restricted as drivers of reductions in direct cross-border loans differ from those for local affiliates’ lending, especially for impaired banking systems. Home bias induced by government interventions, however, affected both equally.

How does domestic monetary policy in systemic countries spillover to the rest of the world? This paper examines the transmission channel of domestic monetary policy in the cross-border context. We use exogenous shocks to monetary policy in systemically important economies, including the U.S., and local projections to estimate the dynamic effect of monetary policy shocks on bilateral cross-border bank lending. We find robust evidence that an increase in funding costs following an exogenous monetary tightening leads to a statistically and economically significant decline in cross-border bank lending. The effect is weakened during periods of high uncertainty. In contrast, the effect is found to not vary according to the degree of borrower country riskiness, further weakening support for the international portfolio rebalancing channel.

This book discusses the risks and opportunities that arise in Emerging Asia given the context of a new environment in global liquidity and capital flows. It elaborates on the need to ensure financial and overall economic stability in the region through improved financial regulation and other policy measures to minimize the emergent risks. "Managing Elevated Risk: Global Liquidity, Capital Flows, and Macroprudential Policy—An Asian Perspective" also explores the range of policy options that may be deployed to address the impact of global liquidity on domestic financial and socio-economic conditions including income inequality. The book is primarily aimed at policy makers, financial market regulators and supervisory agencies to help them improve national regulatory systems and to promote harmonization of national regulations and practices in line with global standards. Scholars and researchers will also gain important information and knowledge about the overall impacts of changing global liquidity from the book.

This paper studies the nature of spillover effects in bank lending flows from advanced to the emerging market economies and identifies specific channels through which such effects occur. Based on a gravity model we examine a panel data set on cross-border bank flows from 17 advanced to 28 emerging market economies in Asia, Latin America and central and eastern Europe from 1993 to 2008. The empirical analysis suggests that global as well as country specific factors are significant determinants of cross-border bank flows. Greater global risk aversion and expected financial market volatility seem to have been the most important factors behind the decrease in cross-border bank flows during the crisis of 2007-08. The decrease in cross-border loans to central and eastern Europe was more limited compared to Asia and Latin America, in large measure because of the higher degree of financial and monetary integration in Europe, and relatively sound banking systems in the region. These results are robust to various specification, sub-samples and econometric methodologies.
