The European Financial Stability Facility (EFSF) was a temporary crisis resolution mechanism established in 2010 to provide financial assistance to eurozone countries in difficulty. It was succeeded by the permanent European Stability Mechanism (ESM) in 2012.
Example
“During the eurozone debt crisis, the EFSF provided bailout loans to Greece, Ireland, and Portugal, helping stabilize their economies and preventing a cascade of sovereign defaults that could have shattered the euro.”
