Effect on interest rates

The introduction of the euro has decreased the interest rates of most members countries, in particular those with a weak currency.As a consequence the market value of firms from countries which previously had a weak currency has very significantly increased. The countries whose interest rates fell most as a result of the euro are Greece, Ireland, Portugal, Spain, and Italy.

Price convergence
The evidence on the convergence of prices in the eurozone with the introduction of the euro is mixed. Several studies failed to find any evidence of convergence following the introduction of the euro after a phase of convergence in the early 1990s. Other studies have found evidence of price convergency, in particular for cars. A possible reason for the divergence between the different studies is that the processes of convergence may not have been linear, slowing down substantially between 2000 and 2003, and resurfacing after 2003 as suggested by a recent study (2009).

Tourism
A study has found that the introduction of the euro has had a positive effect on tourism flows within the EMU, with an increase of 6.5%.
