If they dig oil they need to create a sovereign fund, tie it to the american stock market like Saudi arabia which is pegged to real hard assets and growth, or else it will be spent on useless image related things that have no return on investment. Assets can be liquidated in a few weeks and converted to cash when needed for only PUBLIC Projects not individual wallets(which has no roi) and ends up being consumed not re-generated.
Infact it must have all member state signatures and parliament approval to withdraw any cash from sovereign fund. I think we need an added layer of safety n check n balances of Isimo reserve powers not political power like they have now. Reserve powers to save the nation if the institutions(courts,parliament) fail to do so due to political fall outs, monitor and sign sovereign funds release for public investment, recognize the new govt who wins elections, etc. Reserve powers that are meaningful and holistic in it's impact not down to day to day govt matters tho
