If spending on defence were to rise to 3.5% of GDP, the debt level would increase by an additional 2.5% percentage points each year.

In ten years, the general gov debt ratio could have risen to 90%, although this also depends on inflation and is therefore not easy to forecast. However, investors are likely to demand higher risk premiums for German gov debt. Looking at the yield on German 10s , the peak has probably not yet been reached.
