June 2016The Spillovers, Interactions, and (Un)Intended Consequences of Monetary and Regulatory Policies
with Kristin Forbes, Dennis Reinhardt: w22307
Have bank regulatory policies and unconventional monetary policies—and any possible interactions—been a factor behind the recent “deglobalisation” in cross-border bank lending? To test this hypothesis, we use bank-level data from the UK—a country at the heart of the global financial system. Our results suggest that increases in microprudential capital requirements tend to reduce international bank lending and some forms of unconventional monetary policy can amplify this effect. Specifically, the UK’s Funding for Lending Scheme (FLS) significantly amplified the effects of increased capital requirements on cross-border lending. Quantitative easing did not appear to have a similar effect. We find that this interaction between microprudential regulations and the FLS can explain roughly 30% of ...

February 2016Does Government Intervention Affect Banking Globalization?
with Anya Kleymenova, Andrew K. Rose: w21981
Using data from British and American banks, we provide empirical evidence that government intervention affects banking globalization along three dimensions: depth, breadth and persistence. We examine depth by studying whether a bank’s preference for domestic, as opposed to external, lending (funding) changes when it is subjected to a large public intervention, such as bank nationalization. Our results suggest that, following nationalization, non-British banks allocate their lending away from the UK and increase their external funding. Second, we find that nationalized banks from the same country tend to have portfolios of foreign assets that are spread across countries in a way that is far more similar than either private banks from the same country or nationalized banks from different ...


February 2012Does Macro-Pru Leak? Evidence from a UK Policy Experiment
with Shekhar Aiyar, Charles W. Calomiris: w17822
The regulation of bank capital as a means of smoothing the credit cycle is a central element of forthcoming macro-prudential regimes internationally. For such regulation to be effective in controlling the aggregate supply of credit it must be the case that: (i) changes in capital requirements affect loan supply by regulated banks, and (ii) unregulated substitute sources of credit are unable to offset changes in credit supply by affected banks. This paper examines micro evidence--lacking to date--on both questions, using a unique dataset. In the UK, regulators have imposed time-varying, bank-specific minimum capital requirements since Basel I. It is found that regulated banks (UK-owned banks and resident foreign subsidiaries) reduce lending in response to tighter capital requirements. But u...
May 2011Financial Protectionism: the First Tests
with Andrew K. Rose: w17073
We provide the first empirical tests for financial protectionism, defined as a nationalistic change in banks' lending behaviour, as the result of public intervention, which leads domestic banks either to lend less or at higher interest rates to foreigners. We use a bank-level panel data set spanning all British and foreign banks providing loans within the United Kingdom between 1997Q3 and 2010Q1. During this time, a number of banks were nationalised, privatised, given unusual access to loan or credit guarantees, or received capital injections. We use standard empirical panel-data techniques to study the "loan mix," domestic (British) loans of a bank expressed as a fraction of its total loan activity. We also study effective short-term interest rates, though our data set here is much sma...
