Staff Working Paper No. 860
By Dennis Reinhardt, Stephen Reynolds, Rhiannon Sowerbutts and Carlos van Hombeeck
We examine how banks’ cross-border lending reacts to changes in liquidity regulation using a new dataset on Individual Liquidity Guidance (ILG), which was enacted in the UK from 2000 to 2015 and is similar to the Basel III Liquidity Coverage Ratio. A one percentage point increase in liquidity requirements to total assets reduces UK resident banks’ cross-border lending growth by around 0.6 percentage points and both bank and non-bank lending are affected. But quality matters: an increase in the holdings of High Quality Liquid Asset (HQLA) qualifying sovereign debt offsets some of the reduction in total cross-border lending growth. Furthermore, the strongest reduction is driven by foreign subsidiaries from countries where sovereigns do not issue HQLA; in contrast subsidiaries from countries issuing HQLA are able to protect their lending to unrelated entities and cut their intragroup lending instead. Banks with a higher deposit share as a consequence of established retail operations, such as those headquartered in the UK, are also able to offset the effects of increases of liquidity requirement on cross-border lending.
