Troika
In the sovereign debt crisis, beginning approximately in 2009, in the European region which uses the Euro as currency, three institutions, the European Central Bank (ECB), the European Commission (EC), and the International Monetary Fund (IMF) have taken the responsibility of monitoring the crisis and making policy recommendations. Collectively, these three are, sometimes irreverently, called the Troika.
From the blog www.nakedcapitalism.com, March 4, 2013:

"Even though we were keen about how voter repudiation of austerity in the Italian elections last week was throwing a wrench in the Troika’s austerity plans, we also warned, based on the example of Greece, that they’d try to neutralize the results."
