Much of this foreign saving came from fast-growing emerging market countries in Asia and other places where consumption has lagged behind rising incomes, as well as from oil-exporting nations that could not profitably invest all their revenue at home and thus looked abroad for investment opportunities.
Indeed, the net inflow of foreign saving to the United States, which was about 1-1/2 percent of our national output in 1995, reached about 6 percent of national output in 2006, an amount equal to about $ billion in today's dollars. Saving inflows from abroad can be beneficial if the country that receives those inflows invests them well.
