The term tradable refers to something that can be bought and sold, or exchanged for another item. In economics, it is often used in relation to assets such as stocks, bonds, commodities, currencies, and derivatives which are all financial instruments that can be traded on markets. The concept of tradability implies that these securities have a value in the marketplace and can be easily converted into cash or other assets through transactions with willing buyers and sellers. In essence, something is considered tradable if it has liquidity, meaning it can be quickly bought or sold without causing significant fluctuations in its price.
