The coordination of indebtness of states and, consequently, local government units, is becoming increasingly more important all over the world. The effects caused by the excessive levels of debt can be observed not only in Poland but all over the world, which greatly intensified the financial crisis that occurred in 2008. This publication will examine a problem of the impact of capital expenditure on the deficit in the biggest cities in Poland, which as a consequence increases their debt. The aim of the study is to answer the question whether capital expenditures have a significant impact on the deficit in metropolitan areas in Poland and if excessive debt brake policy may affect investment in major Polish cities. As the study shows capital expenditures, which are so crucial to the development of infrastructure of the metropolises in Poland, do not play a significant impact on the deficit. Despite a constant volume of capital expenditure in the period covered by the study there was a significant decrease in the size of the deficits of the metropolises. Therefore the policy of controlling the debt level does not limit capital expenditure in the metropolises by the lack of effect of that category on the development of deficits.
