However, it is unlikely that trade in financial markets is completely free in this day and age. There are many supranational regulatory bodies for global financial markets, including the Basel Committee on Banking Supervision, the International Organization of the Financial Markets Authority (IOSCO) and the Committee on Capital Movements and Invisible Transactions. Governments with free trade policies or agreements do not necessarily abandon import and export controls or eliminate all protectionist policies. In modern international trade, few free trade agreements lead to completely free trade. A government does not need to take concrete steps to promote free trade. This upside-down attitude is called “laissez-faire trade” or trade liberalization. It should be noted that with regard to the qualification of the original criteria, there is a difference in treatment between inputs originating and outside a free trade agreement. Inputs originating from a foreign party are normally considered to originate from the other party when they are included in the manufacturing process of that other party. Sometimes the production costs generated by one party are also considered to be those of another party. Preferential rules of origin generally provide for such a difference in treatment in determining accumulation or accumulation. This clause also explains the impact of a free trade agreement on the creation and diversion of trade, since a party to a free trade agreement is encouraged to use inputs from another party to allow its products to originate.  The creation of free trade zones is seen as an exception to the nation`s most privileged principle (MFN) in the World Trade Organization (WTO), as the preferences that parties to a free trade area agree to each other go beyond their membership obligations.
 Although GATT Article XXIV authorizes WTO members to establish free trade zones or to conclude interim agreements necessary for their establishment, there are several conditions relating to free trade zones or interim agreements leading to the creation of free trade zones. Since WTO members are required to communicate their free trade agreements to the secretariat, this database is based on the official source of information on free trade agreements (called the WTO-language regional trade agreement). The database allows users to obtain information on trade agreements that are communicated to the WTO by country or theme (goods, services or goods and services). This database provides users with an up-to-date list of all existing agreements, but those that are not notified to the WTO may be lacking. In addition, reports, tables and graphs containing statistics on these agreements, including preferential tariff analysis, are presented.  Both the creation of trade and the diversion of trade have a decisive impact on the establishment of a free trade agreement.
