The second way in which free trade agreements are seen as public goods is related to the trend towards their „deepening”. The depth of a free trade agreement refers to the additional types of structural policies it covers. While older trade agreements are considered „flatr” because they cover fewer areas (such as tariffs and quotas), recent agreements deal with a number of other areas, from services to e-commerce to data localization. Since transactions between parties to a free trade agreement are relatively cheaper than transactions with non-parties, free trade agreements are traditionally considered excluded. Now that deep trade agreements will improve regulatory harmonization and increase trade flows with non-parties, thereby reducing the exclusionability of the benefits of the FTA, next-generation free trade agreements are taking on essential characteristics of public goods.  In the modern world, free trade policy is often implemented through a formal and mutual agreement of the nations concerned. However, a free trade policy may simply be the absence of trade restrictions. However, full free trade in financial markets is unlikely in our time. There are many supranational countries regulating global financial markets, including the Basel Committee on Banking Supervision, the International Organization of the Securities Commission (IOSCO) and the Committee on Capital Movements and Invisible Transactions.
These occur when one country imposes trade restrictions and no other country reciprocates. A country can also unilaterally ease trade restrictions, but this rarely happens. This would put the country at a competitive disadvantage. The United States and other developed countries are only doing this as a kind of foreign aid to help emerging economies strengthen strategic industries that are too small to pose a threat. It helps emerging market economies grow and creates new markets for U.S. exporters. The trade agreement database provided by itC`s Market Access Card. With hundreds of free trade agreements currently in place and under negotiation (around 800 under ITC`s Rules of Origin Facilitator, including non-reciprocal trade agreements), it is important for businesses and policymakers to keep an eye on their status. There are a number of custodians of free trade agreements that are available at the national, regional or international level.
Among the most important are the database on Latin American free trade agreements created by the Latin American Integration Association (LAIA), the database maintained by the Asian Centre for Regional Integration (ARIC) containing information agreements between Asian countries and the portal on european union negotiations and free trade agreements.  The Market Access Card was developed by the International Trade Centre (ITU) to facilitate market access issues for businesses, governments and researchers. The database, visible through the market access map online tool, contains information on tariff and non-tariff barriers to trade in all active trade agreements, not limited to those officially notified to the WTO. .
