Meanwhile, the bank index in Europe has also turned negative (-0.3%) after a decent start earlier in the day. Looking over to the major indices in the region, they have also pared their early gains seen here to be up by just 0.1% across the board now.

There aren't any major headlines as it just seems like investors are digesting the post-banking turmoil feels alongside some trepidation ahead of key inflation data later in the week.
