Since 2010, official discussion of Greek debt has moved fitfully from fantasy to gradually dawning reality. The rescue program for Greece launched that year assumed that a falling debt ratio could be achieved without any private debt write-offs. After a huge restructuring of privately held debt in 2011, the ratio was forecast to reach 124% by 2020, a target the International Monetary Fund believed could be achieved, “but not with high probability.” Today, the IMF believes that a debt ratio of 173% is possible by 2020, but only if Greece’s official European creditors grant significant further debt relief. A significant write-down is inevitable, and the longer it is put off, the larger it eventually will be.
