Editing Euro (section)

===Transaction costs and risks===

The most obvious benefit of adopting a single currency is to remove the cost of exchanging currency, theoretically allowing businesses and individuals to consummate previously unprofitable trades. For consumers, banks in the eurozone must charge the same for intra-member cross-border transactions as purely domestic transactions for electronic payments (e.g., [[credit card]]s, [[debit card]]s and [[cash machine]] withdrawals).

Financial markets on the continent are expected to be far more [[market liquidity|liquid]] and flexible than they were in the past. The reduction in cross-border transaction costs will allow larger banking firms to provide a wider array of banking services that can compete across and beyond the eurozone. However, although transaction costs were reduced, some studies have shown that [[risk aversion]] has increased during the last 40 years in the Eurozone.<ref>Benchimol, J., 2014.
