In 1990 the newly unified Republic of Yemen inherited an unsustainable debt burden amounting to roughly 106 percent of gross domestic product. Debt rescheduling by the Paris Club creditor countries in the 1990s coupled with assistance from the World Bank’s International Development Agency resulted in a drop in Yemen’s debt stock to US$5.4 billion (an estimated 39 percent of gross domestic product) by year-end 2004. According to the Central Bank of Yemen, Yemen’s debt stock was US$5.2 billion (an estimated 33 percent of gross domestic product) by year-end 2005.
Yemen does not have a stock exchange, therefore limiting inward portfolio investment. Portfolio investment abroad is also very limited, with the result that portfolio flows are largely unrecorded by authorities.
