“Eurocrat” or “eurocrat” (Euro/European + bureaucrat) was first used in 1961 to designate officials in the European Economic Community (Common Market). Members of the Euopean Union where the euro is the official currency have also had their representatives called “Eurocrats.”
 
It is not known who coined “Eurocrat,” but the term appeared in The Economist by July 29, 1961 and the Daily Mail (London) by at least August 1961.

Wikipedia: Euro
The euro (sign: €; code: EUR) is the official currency of the eurozone: 17 of the 27 member states of the European Union. It is also the currency used by the Institutions of the European Union. The eurozone consists of Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also used in a further five European countries (Montenegro, Andorra, Monaco, San Marino and Vatican City) and the disputed territory of Kosovo. It is consequently used daily by some 332 million Europeans. Additionally, over 175 million people worldwide use currencies which are pegged to the euro, including more than 150 million people in Africa.
 
The euro is the second largest reserve currency as well as the second most traded currency in the world after the United States dollar.

A year or so ago, the Commission people were branded with a tag so apt that it seems amazing they had escaped it for so long — “the Eurocrats.” Nobody knows who first thought of it, hut it was disseminated chiefly by Margot Lyon Mayne, a Common Market wife with no children, who, rather than accept a solitary life during her husband’s long hours, had become a correspondent for various British newspapers and magazines, including the Guardian,

The first reaction of a ‘Eurocrat’ on being presented with a problem is to reach for his copy of the Rome Treaty, and study the relevant passages with immense care to see what consequences for policy-making can be extracted from them.

Financial crisis: Eurocrats are terrified of democracy
Greece’s prime minister George Papandreou is in the doghouse only because he dared to offer voters a choice.
By Daniel Hannan

Shall I tell you the truly terrifying thing about the EU? It’s not the absence of democracy in Brussels, or the ease with which Eurocrats swat aside referendum results. It’s the way in which the internal democracy of the member states is subverted in order to sustain the requirements of membership.
