A growing number of countries are forced to finance their investment by their domestic savings: This is very inefficient
A growing number of countries are faced with: An inability to finance an external deficit, due to other countries' refusal to keep on lending to them (which is the case of the peripheral euro-zone countries , for example ); High volatility of capital flows, alternately entering and leaving, and thereby seriously destabilising the economy if the country has a structural external deficit (which is the case of the large emerging countries , for example ). In the end, therefore, these countries are forced to finance their investment by their domestic savings, which results in major inefficiency and a major loss of growth, because global savings are not allocated efficiently.
