ECB stands ready to temporarily increase Italian bond purchases in case of yield spikes over referendum
Italy would formally have to ask for help if it needs longer-term support
Maybe that's why ECB purchases were notably lower last week but that might be me grasping at straws. What's also a touch strange is that the numbers were lower despite being in the holiday front run period. The ECB said they would be stepping up purchases between Nov 20th - Dec 21st to cover the period over Christmas. Maybe they have something up their sleeve at the Dec 8th meeting they need to focus on ;-)
