The economy of Europe comprises more than 744 million people in 50 countries. The formation of the European Union (EU) and in 1999, the introduction of a unified currency, the Euro, brings participating European countries closer through the convenience of a shared currency and has led to a stronger European cash flow. The difference in wealth across Europe can be seen roughly in former Cold War divide, with some countries breaching the divide (Greece, Estonia, Portugal, Slovenia and the Czech Republic). Whilst most European states have a GDP per capita higher than the world's average and are very highly developed (Liechtenstein, Luxembourg, Monaco, Andorra, Norway, Sweden, Denmark, Netherlands, Switzerland, United Kingdom, Ireland, Germany), some European economies, despite their position over the world's average in the Human Development Index, are poorer. Europe in banking had total asset more than $50 trillion and its global management had asset more than $20 trillion.
