Which is the oldest, still current, government debt?
The answer of course depends on definitions since debts usually are "rolled over" at least every couple of decades and with time you can't separate pound A that was borrowed at time X and pound B that was borrowed at time Y. I am looking for something along these lines:
- A state that has been constantly in debt.
- A state that haven't defaulted on their payments during the period, or if they defaulted and then started to pay again, paid all interest that was due.
- Never any agreement with the debt holders to restructure the debt (e.g., a "haircut" where the debt holders agree to only receive, say, 50 % of the actual debt).
I guess some common-sense-restrictions about changing currency (e.g., Germany - the introduction of D-mark after WW2 could probably be seen as an interruption that disqualifies it while the switch from D-mark to Euro 2002 is not disqualifying.) and peaceful merging/splitting of countries and similar events also applies.
I suspect countries like Switzerland and Sweden, that are both old and haven't been to war or revolutions for hundreds of years, are likely candidates.
