One of the tasks of the KNF expressly defined in the Act on financial market supervision is to take actions for the development of that market. It is about both stimulating its growth and taking care of its competitiveness and stability – all that being done so that the financial market can support the development of Poland’s economy. Higher competitiveness of the economy is determined by higher labour productivity rates, and these depend on capital accumulation rate (capital deepening), in other words – the level of investment. At the same time, a material rise in investment-to-GDP ratio (capital deepening) requires appropriate funding sources, i.e. a deeper financial market (financial deepening). This happens, since a developed financial market mobilises savings, which in turn increases the supply of funds for investment purposes, reduces the costs of capital through competition and better risk valuation, improves capital allocation and allows long-term funding.
