This page presents the results of a simulation conducted by students at ESCP Europe Business School. The aim was to uncover the amount of interlinked debt between Portugal, Ireland, Italy, Greece, Spain, Britain, France, and Germany; and then see what would happen if they attempted to cross cancel obligations.
The results were astounding:
- The countries can reduce their total debt by 64% through cross cancellation of interlinked debt, taking total debt from 40.47% of GDP to 14.58%
- Six countries – Ireland, Italy, Spain, Britain, France and Germany – can write off more than 50% of their outstanding debt
- Three countries – Ireland, Italy, and Germany – can reduce their obligations such that they owe more than €1bn to only 2 other countries
- Ireland can reduce its debt from almost 130% of GDP to under 20% of GDP
- France can virtually eliminate its debt – reducing it to just 0.06% of GDP
