The state market is a trade in which the nations sell the resources of their budget in exchange for state money and buy with that same money offers of resources posted by other countries. It works the same as the players ' market, except for a number of features:
The seller is any parliamentarian who manages to pass a law to sell resources, where the desired offer is indicated. The Minister of Economy, monarch or dictator can do so immediately, just as they can apply on another nation a cancellation of imports (you stop perceiving the offers of that state) or exports (the other State ceases to perceive your offers). Budget resources are being sold in exchange for state money.
The buyer can only be the leader of the nation and the minister or economic adviser (with State budget) or the governor of an autonomy (with autonomic budget) of a state that does not have canceled the exports with the state of the offer. The transaction is done immediately as soon as the offer is accepted. They buy the resources of the offer in exchange for state money.
At the time of trading, the offers and demands are much lower, making the fluctuations much more unpredictable and broad. This added that the offers cannot be cancelled by the seller make the investment something impossible, or at least insecure.
Generally, the value of state money is lower than that of user money, so resources appear more expensive than in the market. This is the main reason why you should not donate user money to the budget because it is devalua.
