Domestic saving in Turkey fell to a low of 12.7 percent of GDP in 2010, the lowest rate since 1980. Low domestic saving matters for at least two reasons. First, domestic savings finance investment and thus growth. Cross-country data suggest a positive association, especially for developing countries, between saving, investment, and growth. Second, the low level of domestic saving has increased dependence on foreign financing of Turkish investments, fueling an expansion in the external current account deficit and jeopardizing the sustainability of growth.
