One of the most difficult aspects of implementing an international agreement is the need to take into account different cultures, different structural models, the complexity of public order and existing rules. The management of the banks will determine the strategy of the company as well as the country in which a certain type of business will be established, partly on the basis of the final interpretation of Basel II by legislators and regulators from different countries. [Citation required] One instrument that facilitates the proper functioning of financial markets is a series of international agreements on banks, called the Basel Agreements. These agreements coordinate the regulation of global banks and provide “an international framework for internationally active banks.” Agreements are opaque to non-bankers, but they are the backbone of the financial system. The Basel Agreements were created to protect against financial shocks, which harms the real economy of a weakening capital market, unlike a mere disruption. Some countries have introduced fundamental versions of the new agreement, but in the United States, Basel II is experiencing a painful, controversial and longer commitment (even though the big banks have been working for years to meet their terms). Many of these problems are inevitable: the agreement attempts to coordinate the capital requirements of banks at the national level and beyond the size of the banks. International coherence is quite difficult, but also the scale of requirements – in other words, it is very difficult to design a plan that gives no advantage to a banking giant over a smaller regional bank. If market participants have a sufficient understanding of a bank`s activities and that of a bank to manage its exposures, they are in a better position to distinguish between banking organizations so that they can reward those who manage their risks prudently and penalize those who do not. This pillar aims to complement the minimum capital requirements and prudential control procedure by developing a series of advertising obligations allowing market participants to assess the adequacy of an institution`s capital. On September 30, 2005, the four U.S. federal banks (the Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation and the Office of Thrift Supervision) announced their revised plans for the United States.
