Bailouts have always worked like this. Spain, Ireland, Portugal, France, etc., bailed out their banks. Then when some of these countries couldn't get money on the markets due to their debt, they had to be "saved", then later the ECB finally started to buy these countries' bonds. The ECB couldn't do it before because it isn't supposed to do it, and Germany was against it.
The ECB made the problem worse because it didn't act like a central bank in the first place like the US Fed did. Buying up bonds / QE wasn't their job. Things went south very quickly and they only acted within their role. Not until Draghi delivered his 'whatever it takes' speech did they act like a central bank.
The way they got into this mess? While Spain and Ireland had real estate bubbles, many French & Italian banks made big mistakes. Pre - Euro they could buy government bonds with yields around 15%, which is phenomenal. But, after the Euro came into being, Euro area bonds began behaving like a bloc and gravitated to German yields (around 2%). For a long time, the Euro bond acted like a German bund. So, the banks that had been getting 15% yield, leveraged up significantly to offset the lower yields. But sometime in 2011 (?), when Greece began to wobble yields began behaving individually again, and as the threat of large losses on Greek govt bonds rose, banks looked to sell out of Portuguese debt before everyone else did, creating a spike in Portuguese yields. Contagion. The ECB didnt step in until the situation was dire.
edit: For Italy, like Monte Paschi, they made a shit deal that got wiped out. Many of their junior bondholders are retail Italian investors so the government wants to bail them out but the new ECB rules say no bail out. So, if no bail out for Monte Paschi, then Italy says no bail out for Deutsche bank.
There will be a bail out when Monte Paschi gets low enough.
