what you just talked about in the last sentence is called "mark to market" you clearly need to read some texts on economics if you don't understand the function of money as a means to denominate relative value of goods (and services) available on the market all market goods and services are worth all the money that can be spent on them decrease the supply of goods and the price of the assets goes up because there is more money to go to them increase the supply of money and the prices of goods goes up to compensate, as more money is going to be available to spend it's really not complicated i don't get what you are confused about
