Working Paper No. 498
By Dennis Reinhardt and Steven J Riddiough
We decompose gross cross-border bank-to-bank funding between arms-length (interbank) and related (intragroup) funding, and show that while interbank funding is withdrawn when global risk is high, intragroup funding remains stable during these periods, despite being more volatile on average. We disaggregate intragroup funding further and find advanced-economy parent banks benefit from inflows during episodes of heightened global risk. However, we do not find evidence of significantly reduced intragroup funding to foreign affiliates during these periods. Our results are in contradiction with theoretical predictions on the behaviour of cross-border banking flows, and help explain why certain banking systems lost more cross-border bank-to-bank funding than others during the global financial crisis.
