The Vatican passed Moneyval's first test in the summer of 2012 but received poor or failing grades for its financial watchdog agency and the IOR, specifically the bank's ability to ensure that its customers and transactions were clean.
Promontory has been going through the IOR's accounts to ensure they comply with international norms. That task was due to have been completed at the end of 2012 but has dragged on. The Holy See has also passed a series of new laws to respond to Moneyval's recommendations ahead of the new evaluation round.
At the same time, Pope Francis named a commission of inquiry to look into the bank's legal structure and activities as part of his overall reform of the Holy See's finances.
Marranci, 60, retired in 2011 from Italy's Banca Nazionale del Lavoro, where he had held several accounting positions and, among other jobs, was chief financial officer of BNL's London branch.
