The Vatican "is already a credible partner," said Rene Bruelhart, director of the Vatican's Financial Intelligence Authority (FIA), who was appointed last year to help reform efforts.
The FIA document said there had been six reports of suspicious financial activity in the Vatican last year and three requests of information from foreign authorities but did not provide details.
The report also showed there were 598 declarations of cross-border transfers of more than 10,000 euros ($13,000) into the Vatican and 1,782 outgoing ones in 2012.
Bruelhart, a Swiss lawyer, previously helped Liechtenstein shed its shady reputation.
