The global financial cycle: Notion, empirical evidence and policy implications

The article deals with the notion of the global financial cycle proposed by H. Rey and her co-authors. The driving forces of the global financial cycle are discussed along with the findings of the empirical papers testing this concept. It is shown that recognizing US monetary policy shocks as a major driver of the global financial cycle does not undermine the validity of the well-known "trilemma": using the floating exchange rate regime still partly cushions developing and emerging market economies from external shocks. Its effect can be reinforced if macroprudential policy measures or partial restrictions on capital mobility are also applied. The review concludes by discussing possible extensions to the concept of global financial cycle.
