Cross-border prudential policy spillovers: how much? How important? Evidence from the International Banking Research Network
The development of macroprudential policy tools has been one of the most significant changes in banking regulation in recent years. In this multi-study initiative of the International Banking Research Network, researchers from fifteen central banks and two international organizations use micro-banking data in conjunction with a novel data set of prudential instruments to study international spillovers of prudential policy changes and their effects on bank lending growth. The collective analysis has three main findings. First, the effects of prudential instruments sometimes spill over borders ...
Cross-border diversification in bank asset portfolios
Taking the mean-variance portfolio model as a benchmark, we compute the optimally diversified portfolio for banks located in France, Germany, the U.K., and the U.S. under different assumptions about currency hedging. We compare these optimal portfolios to the actual cross-border assets of banks from 1995-1999 and try to explain the deviations. We find that banks over-invest domestically to a considerable extent and that cross-border diversification entails considerable gain. Banks underweight countries which are culturally less similar or have capital controls in place. Capital controls have ...
The international transmission of monetary policy
This paper presents the novel results from an internationally coordinated project by the International Banking Research Network (IBRN) on the cross-border transmission of conventional and unconventional monetary policy through banks. Teams from seventeen countries use confidential micro-banking data for the years 2000 through 2015 to explore the international transmission of monetary policies of the United States, the euro area, Japan, and the United Kingdom. Two other studies use international data with different degrees of granularity. International spillovers into lending to the private ...
International banking and liquidity risk transmission: lessons from across countries
Activities of international banks have been at the core of discussions on the causes and effects of the international financial crisis. Yet we know little about the actual magnitudes and mechanisms for transmission of liquidity shocks through international banks, including the reasons for heterogeneity in transmission across banks. The International Banking Research Network, established in 2012, brings together researchers from around the world with access to micro-level data on individual banks to analyze issues pertaining to global banks. This paper summarizes the common methodology and ...
Cross-Country Evidence on Transmission of Liquidity Risk through Global Banks
Over the past thirty years, the typical large bank has become a global entity with subsidiaries in many countries. In parallel, financial liberalization has increased the interconnectedness of banking systems, with domestic banking systems becoming more exposed to shocks transmitted through foreign banks. This globalization of banking propagated liquidity risk during the global financial crisis and subsequent euro area crisis. Unfortunately, little is known about how cross-border operations of global banks transmit liquidity shocks between countries. The seminal work by Peek and Rosengren ...
Will Capital Flows through Global Banks Support Economic Recovery?
While policymakers around the world have aggressively and swiftly reacted to the common negative economic shock from COVID-19, the timing and forms of policy responses in the economic recovery stage may be more geographically differentiated. The range in policy responses, along with variations in the financial health of banks, likely will affect the flow of international credit through global banks. In this post, we ask whether, based on historical precedent, global banks are likely to provide additional support to the economic recovery in the locations they serve.
Complexity and Riskiness of Banking Organizations: Evidence from the International Banking Research Network
Complexity of banks can have important ramifications for the performance and the risks of the banking system. Financial sector reforms that were implemented in the past decade have thus aimed to reduce and to better manage the risk implications of bank complexity. Yet, surprisingly little is known about changes in complexity across countries, its drivers, and its effects. The International Banking Research Network (IBRN) used data and analytical advances to generate rich cross-country insights on the complexity and riskiness of banking organizations. The initiative has yielded four key ...
