Italy's 2011-2012 sovereign debt crisis
Italian 10-year bond yields spiked toward 7% during the eurozone debt crisis, a level investors saw as unsustainable for a country with debt near 120% of GDP. Silvio Berlusconi's government fell in November 2011 and was replaced by Mario Monti's technocrat cabinet, which passed austerity including pension reform and a property tax.
Yields eventually fell after the European Central Bank signaled it would do whatever it takes to save the euro in July 2012.
Italy avoided a bailout but its debt stayed high and growth stagnated for years, shaping its reputation among northern European creditors.
Shows how quickly borrowing costs move when a high-debt economy faces an external shock, and how austerity becomes politically explosive under market pressure.
