The latest aggravation in the Greek crisis has strained nerves on the eurozone debt market, but unlike four years ago there has been no contagion across the single currency bloc.
The chaotic nature of the bailout negotiations which nearly sent Greece into default exacerbated market volatility, but the rise in yields was largely confined to Greek bonds.
While in 2011 Greece's problems rippled across the eurozone as spooked investors demanded higher returns from other countries that in turn pushed them into financial trouble, this time yields barely budged.
This year "there was pollution, but not contagion" to other eurozone countries, said Patrick Jacq, a debt market specialist at French bank BNP Paribas.
"There was no contagion, that is the big difference with three or four years ago," said Frederic Gabizon, who heads up bond markets at HSBC.
In a sort of self-fulfilling prophecy four years ago, investors worried about the sustainability of the debt of weak eurozone nations demanded higher returns, thus weakening the finances of those countries.
Portugal ended up needing to take an full EU-IMF bailout in 2011 while Spain got away with just a bailout of its banks in 2012.
This year, even at the most difficult moments in the negotiations between Greece and its creditors "there weren't massive movements to sell the bonds" of Spain or Italy, said Gabizon.
Bond market specialist Jean-Francois Robin at the investment bank Natixis said "the magnitude is completely different" this year.
He cited as an example the rate of return to investors on 10-year Portugese sovereign bonds, which shot up to 18 percent at the beginning of 2012 but only rose to 3 percent this time.
The first bond emission by the European Union after Athens and the eurozone nations agreed on a third bailout to Greece worth up to 86 billion euros ($94 billion) demonstrated the confidence of investors, said Gabizon who led the operation.
"In just one hour and 15 minutes it generated demand of 1.8 billion euros, or 3 times the 600 million euros the EU wanted to borrow for five years, for a borrowing rate of 0.272 percent, a real success," he said.
- The ECB is there -
The reaction by markets this time around demonstrated the situation had changed significantly since 2011.
"The eurozone is better organised, and member states are also in a different shape. Portugal and Spain have undertaken considerable reforms," said Robin, adding that economic growth has also resumed.
"Above all the European Central Bank is out there buying bonds every day," added Robin, referring to the quantitative easing (QE) programme launched in March, under which the ECB purchases around 60 billion euros of debt of eurozone member countries and companies.
The programme provides powerful support to bond markets and keeps interest rates low. But even that didn't prevent an upward swing in the second quarter of the year.
In the first quarter, galvanised by the ECB's announcement of its QE programme, sovereign yields dropped -- in some cases into negative territory as investors sought a safe haven investment amid fears of recession and deflation.
"(But) the second quarter was very tumultuous," said Jacq, citing two periods of significant rises in bond yields.
And analysts agree that Greece played no role in those surges, which began before a Greek euro exit had become a serious possibility.
"There were several catalysts, including better than expected economic statistics and declarations by market heavyweights arguing rates were too low and calling for a sell-off. That's when the market took off," said Jacq, who anticipates more placid activity in the near term.
"The summer should be calmer... but come September -- between the looming rate rise by the US Federal Reserve and negotiations on Greece's debt restructuring -- volatility could make its return," said Robin.
