Among the natural wealth Croatia disposes of, its tourist potential is markedly in first place. Situated on the coast of the Adriatic Sea and indented deeply into the European continent, Croatia is located under the warm sun and the favourable Mediterranean climate. Even though Croatia today sets apart almost one fourth of its foreign-currency income on tourism, which is only the beginning of the exploitation of our possibilities. An exceptional role in obtaining more income from tourism is that of the accommodation capacity, dealing with foreign tourists. They expect not only a smile on their host's face but also comfort, a rich gastronomic offer and hundreds of other services without which the satisfaction of staying in a foreign country is greatly reduced. To see as much as one can with as little effort as possible, get to know the culture, people, landscape, all are the basic wishes of every visiting tourist. The development of tourism is not an aim itself but a subsystem of social development mutual aim. The low efficiency of the use of economic resources is the principle-limiting performer in economic development aim realization. Economic growth and development greatly depend on investments and their efficiency. The investment criteria and motives, and the investment demands, are very different. It is firstly profit or earnings, then workforce employment, increase in standard and material wealth, natural wealth exploitation, development of single economic and non-economic activities, development of individual areas and regions, change of economic and social structures, upgrading of trade and payments balance, etc. The investment carrier in all economic and non-economic activities, and therefore in tourism, have recently appeared besides banks, and they are investment institutions that have taken an ever more significant part in total investments. Today banks in industrially developed and transitional countries are developing new products and services with the help of software support, particularly computer networks, moving time and space limits of traditional banking and substantially facilitating the transfer of financial resources. Banks that finance a project must provide for the investment market and the planning and performing quality as well, particularly profitability. The bank approves credits to private and state companies that carry out the privatisation program without a state warranty, but they expect a full commercial refund from the companies that always have to take upon themselves the risk of investment. The role of the central bank as the creator of the entire monetary politics is, therefore, inevitable.
