The Basel committee on Banking Supervision has suggested banks hold more capital against buy-to-let loans, which Barclays described as a potential game-changer.
It downgraded both OneSavings Bank, down 15.9p to 329.9p, and Paragon, 6.5p lower at 351.6p, to equal weight from overweight.
Fellow FTSE 250 stock SuperGroup was also in negative territory, dropping 150p to 1466p, after a downgrade from Liberum to hold from buy.
At the other end of the leaderboard, Tullow Oil was celebrating finding oil in northern Kenya.
It was the index’s top riser, jumping 10.7p to 162.8p.
AIM-listed law firm Gateley also raised some festive cheer, with news that six-month revenue was up 10.9% and pre-tax profit up 11.5%. The shares rose 1.5p to 103.7p.
