An uneasy calm descended across battered bank bonds and shares on Tuesday, with prices recovering a day after regulators sought to convince investors that the hit facing bond holders of embattled Credit Suisse is isolated. AT1 bonds from others such as Deutsche Bank, UBS and BNP Paribas rose more than 2 cents, data from MarketAxess and Tradeweb showed. On Monday bank AT1 bonds had taken a beating after news that those issued by Credit Suisse would be written down to zero as part of a rescue merger with UBS.
