Honduran Cardinal Oscar Rodriguez Maradiaga, a key adviser in Francis' Group of Eight cardinal cabinet, told the French Catholic newspaper La Croix that creating a "finance secretariat" was needed to better organise the Vatican's diverse financial departments.
He said a cardinal would probably head it, assisted by a permanent advisory body of lay experts.
The development came as Francis and his "G8" cardinals ended their third and final day of meetings to hear proposals for reform by experts who have been studying the Vatican's financial institutions since last summer.
He has paid special attention to the scandal-marred Vatican bank, long accused by Italian authorities of being an off-shore tax haven for well-connected Italians, and the half-dozen independent Vatican finance offices that do everything from managing the money-making Vatican Museums to administering the Holy See's vast real estate holdings.

Francis has called for his church to be particularly attentive to the needs of the poor, and has railed against the injustices of the global capitalist system.
While money can help people achieve goals, "money and economic power can be a means to distance people from one another, confining them to an egocentric and egotistical plane," Francis wrote.
