* Price stability. The average rate of inflation observed over the 12 months preceding EMU accession must not exceed the average in the three best-performing EU member states by more than 1.5 percentage points. In practice, this will most likely mean that inflation rates will need to be below 3%.
* Fiscal sustainability. The general government deficit must be below 3% of GDP. General government gross debt must be below 60% of GDP, or at least on a declining trend.
