Integration has become a second nature of Europeans.. Day-in, day-out, we experience more worldwide integration of markets and this will further develop as –in the end – it will mean real tangible benefits for all stakeholders involved. One of the most important parts of the integration process is the financial integration which could be seen as a complex process which involves institutional, functional, structural and behavioural aspects. The aim of this paper is represented by the assessment of the financial integration degree between the Romanian financial market on the one side and the EU financial markets on the other side, analyzing all the four aspects mentioned above. The final conclusion that could be drawn is that the Romanian financial market integration registered in the last period (especially in the period 2004-2005) a large progress which marks the “maturation” of the national financial market. Despite of these progresses, some significant divergences could be still seen and in consequences this process has to be continued with some further simulative mechanisms.
