The world bank provides a place for dominions both to store their excess funds and to take out loans during emergencies.
The maximum size of a dominion's savings account and the most it can loan at once is determined mainly by the dominion's networth.
Savings account interest rates begin at 4% and gradually decrease as your dominion grows larger and begins to deposit more of its funds.
Loan interest rates begin at 8% and gradually increase as your dominion grows larger and becomes more easily able to pay off loans.
If, while spending commands, your dominion manages to run out of money, a loan will automatically be taken out for the amount you need, and the Bank will respect your state of emergency by allowing you to temporarily exceed your usual loan size limit by 100%.
During the final week of a round, you will not be allowed to take out any additional loans.
