1) To sustainably maintain a debt-to-GDP ratio of 99%, the primary surplus needed is 1.5%. For a 78% debt-to-GDP ratio, the primary surplus is 0.5%. The difference is due to needing a larger surplus to sustain a higher debt level. 2) If the primary surplus is maintained at 1.2% from 2021-2030, debt is not sustainable and will rise above 100% of GDP. To get debt back down to 78% by 2030, the primary surplus would need to be 1.5%. 3) Allowing for variable macroeconomic forecasts and 5% or 30% of debt in foreign currency, debt dynamics are plotted
