Financial instruments can be classified into two main categories: cash instruments and derivative instruments. Cash instruments are financial assets whose value is directly influenced by the market, such as stocks, bonds, and loans. Derivative instruments, on the other hand, are contracts whose value is derived from the performance of underlying assets, indices, or interest rates, including options and futures contracts. Financial instruments are essential in the financial markets and serve various purposes, such as raising capital, managing risk, and facilitating investment.
