I would like to see a way for an alliance to run a central run bank that have a formal tie to the alliance in game (rather than simply being a nation that serves as an offshore to protect from looting).
The alliance bank would be operating cash and resources for immediate needs and it would continue to be looted when a nation is defeated in war. However, the central bank is safe from being looted and tracks all deposits and withdrawals for each nation. The central bank would set the currency, manage the money supply and set interest rates. It would have the capability to accept deposits and make loans from/to members and non-members.
Thanks for soliciting ideas. ?
