On July 21, 2011, the heads of government of the euro area announced a new plan to address the Greek debt crisis. This policy brief presents a simulation exercise that examines whether the new arrangements are likely to provide a sustainable solution. The analysis focuses on four key measures: gross debt relative to GDP; net debt relative to GDP; net interest payments relative to GDP; and amortization of medium-and long-term debt coming due during the year in question, relative to GDP. The new Greek package shows prospective future progress on all four measures, and Greek debt looks much more sustainable after the package than before. Debt also appears considerably more manageable if the criterion is net debt or interest burden rather than gross debt ratio, although even for gross debt the ratio is down substantially by 2020. It also becomes clear that the major contribution of the private-sector involvement (PSI) part of the package is in the form of sharply cutting amortization due, although by avoiding large new borrowing at crisis-level interest rates it also alleviates the interest burden that would otherwise occur.
