Bankers sans borders
The decade before the 2007–09 global financial crisis was characterized by a significant increase in bank globalization, which also coincided with dramatic increases in bank size. International banks became the cornerstone of many financial systems around the world, also in developing countries.
Proponents of international banking emphasized the potential gains in terms of much-needed capital, know-how, and technological improvements that foreign banks bring, leading to more competitive and diversified banking systems, improved resource allocation, and greater financial and economic development.
However, the global financial crisis has led to a significant re-evaluation of this conventional wisdom. With the crisis, there was a backlash against globalization in general, and the emphasis shifted to the role international banks can play in shock transmission. — blog.wb.org/blogs
