Pope Francis' finance minister is on the move, literally.

Four months after he raised eyebrows by taking up residence in the Vatican bank, Cardinal George Pell is moving out and into the permanent offices of his new economy secretariat.

The move coincides with a major reorganization of the Vatican's financial structures ordered by Pope Francis as part of his reform of the Vatican's administration. It also removes any question of Pell's direct authority over the bank, which is governed by a separate commission of cardinals who report to the pope.

Francis tapped the straight-talking Australian to bring order and efficiency to the Vatican's complicated finances. Pell has promised a new era of transparency, budgeting accountability and internationally accepted accounting standards, and has been given broad oversight powers.
