What is the opposite of public debt? The opposite of a budget deficit is a budget surplus
But what is the opposite of public debt?
Instead of govt/state being in debt, having the government have extra money to keep or to lend it to banks or companies.
Say the extra money are kept Instead of being lent. What is the name of such a surplus?
It would be the sum of the budget surplus for the curent year and all the years before.
Such government would be called net lender. However, note that for a country to be net lender it is not required that debt is zero, only that the amount it is lending is higher than its liabilities (debt). A country can chose to have some level of debt even if it is not necessary for it to have it because its revenues are higher than expenses. An example of net lender would be Norway (see here).
