The euro is the official currency of the eurozone, which consists of 19 of the 28 EU member states. It is the second-largest reserve currency in the world after the US dollar.
Since 1999, the euro has been used as an accounting currency in global financial markets. Physical euro coins and banknotes entered into circulation in 2002. In 2009, the euro has become immersed in Europe's sovereign debt crisis which forced the eurozone to adopt a raft of reforms to stabilize the currency.
The US dollar is going from strength to strength while the European single currency is sliding - even more so, since the US Federal Reserve announced there could be further rate hikes next year. At the moment, the euro-dollar exchange rate has almost reached parity.
