Financial globalisation has given international capital flows a central role in the functioning of the global economy and has therefore led to considerable economic research over the past 30 years. Making the most of capital flows by allowing countries to reap their benefits while reducing associated risks has always been a challenge. This challenge became however even more acute in the past decade: following the Global Financial Crisis new concerns have indeed emerged related to the complexity of global financial relations, their role in shock transmission as well the ability of fundamentals to protect countries from financial instability. Against this background, recent research has focused on understanding better the implications of financial globalisation for economic stability and the design of policies. This literature review assesses these recent developments. After reviewing the most important trends in capital flows over the past decade, it takes stock of the discussion on the role of the global financial cycle in driving cross-border capital flows and financial instability, reviews the new findings on the real impact of international capital flows on recipient economies, and provides an overview of the ongoing debates on the role of capital controls and the need for policy coordination.
