The international financial system is a structure of markets within which organizations and individuals trade to support economic commitments made across national borders where buyers and sellers participate in the trade of assets such as equities, bonds, currencies and derivatives. Financial markets are typically defined by having transparent pricing, basic regulations on trading, costs and fees and market forces determining the prices of securities that trade. The international financial market expands rapidly including money and derivatives since early 1980s. The increased integration of financial systems has involved greater cross-border capital flows, tighter links among financial markets, and greater presence of foreign financial firms around the world. The expansion in international financial market also means that establishment and expansion of international investment banks/ firms such as Crosby, Morgan Stanley, JP Morgan, UBS, Franklin, Templeton, Barney & Smith, Union Bank in Swiss etc. Such firms created varieties of investment fund such as hedge fund and mutual trusts. The expansion of such investment funds has enhanced volume of foreign policy initiative (FPI) in the world economy.
