Financial markets can be classified in several ways, including by maturity, seasoning, timing/delivery, and organizational structure. The money market deals in short-term securities of less than 1 year, while the capital market trades long-term securities over 1 year. Primary markets issue new securities, and secondary markets facilitate subsequent trades of already issued securities. Cash markets require immediate delivery, while forward markets schedule future delivery. Exchange markets operate on organized exchanges, and over-the-counter markets consist of decentralized dealers. Financial instruments include assets like currency, loans, deposits, securities, and shares, as well as commitments and pledged assets.
