Pope Francis issued a decree designed to combat money-laundering and prevent any financing of terrorism.
It is the latest move to stamp out abuses at the Vatican bank, which handles funds for the Catholic Church.
The Pope recently set up a commission to investigate the bank and report back to him personally.
Last month the Vatican froze the account of a senior cleric, Monsignor Nunzio Scarano, suspected of involvement in money-laundering.
He and two others were arrested by Italian police in June on suspicion of trying to move 20m euros ($26m; £17m) illegally.
Pope Francis’s number one priority this summer is to sort out the financial mess at the Vatican bank and a parent body which looks after the financial assets of the Holy See, the BBC’s David Willey reports from Rome.
