The largest ?old? industrialised nations ranging from Japan to UK will all suffer a debt curse which in the worst case will extend even to 2084 says the World Competitiveness Yearbook brought out by the International Institute of Management Development (IMD).

Using the debt-stress test, the report estimates that the time taken for these nations to revert back to a bearable public debt level of 60% of its respective GDP will be the highest for Japan (in 2084) and followed by Italy (2060), Portugal (2035), Belgium (2035), US (2033), Iceland (2031), France (2029), Germany (2028), UK (2028), and Canada (2025). India?s position is much more optimistic as it will bring down its debt to 60% of the GDP by 2015.

Argentina, Brazil and India were among those expected to reduce their debt burden to the IMF benchmark by 2015, while Turkey, Switzerland and China were already below the 60% level as of last year, the index found.
