As in many developing countries, capital is the most important factor in economic growth. Because capital is scarce. This scarcity applies to the total capital amount as well as the quality of capital in question. In developing countries, capital element deficiency in general lack of qualifications of specialization in capital in the form of incomplete capital, this deficiency of capital is only eliminated with specialized foreign capital. Developed countries follow various policies to finance exports and form various institutions in this direction. Each country establishes its own export financing mechanism within its current legal framework according to its political and economic situation. In addition, the financing burden of large projects created by the private sector remains above the private sector .In order to alleviate this burden, export credit institutions in many countries contribute to project financing as a source of funding. If we include the state's request for borrowing in order to provide financing, we see that the potential for borrowing of the private sector has fallen. Because the borrowing of financial resources that can be used by the private sector will cause a deficit in the Fund markets, which will cause a rise in interest rates by creating a surplus in the Fund demand, resulting in a contraction in private sector investments. In Economics, this contraction is called the exclusion effect .Domestic savings in many developing countries, including Turkey, are often lagging behind domestic Fund demand .Because the state makes it difficult for private companies to borrow public money by limiting the supply of financing through public offerings. On the other hand, since debt securities issued as a result of government borrowing have the power to trade in capital markets, significant liquidity opportunities are emerging in the market and trading volume increases.
