The possibility of introducing the euro in Hungary has been a key topic in economic
policy debates for decades. Most research has focused on the effects of currency conversion
on monetary policy, while fewer publications have dealt with the changes affecting
companies. The aim of this study is to examine the impact of the introduction of the
euro on companies. It provides a detailed literature review, including international
examples of countries that have successfully joined the euro. This allows for a more
detailed analysis of the advantages, disadvantages, and risks. The study focuses on
the competitiveness of companies. The aim of the study is to provide a structured
presentation of the current situation and to identify the opportunities and challenges
that can be expected in the event of future euro adoption.
