First large downhill flows of capital – from rich countries to poor countries – led to the Latin American debt crisis of the early 1980s. In the 1990s similar flows begat the Asian financial crisis.

Since 2002 the flows have been uphill, from emerging markets and oil-exporting countries to the developed world, especially the US. But the outcome has not been very different. So, it does not seem to matter how capital flows. That it flows in sufficiently large quantities across borders – the celebrated phenomenon of financial globalisation – seems to spell trouble.
