Vatican favors a global financial authority

Today the Pontifical Council for Justice and Peace called for the establishment of a global financial authority.  An excerpt:

[A] long road still needs to be travelled before arriving at the creation of a public Authority with universal jurisdiction. It would seem logical for the reform process to proceed with the United Nations as its reference because of the worldwide scope of its responsibilities, its ability to bring together the nations of the world, and the diversity of its tasks and those of its specialized Agencies. The fruit of such reforms ought to be a greater ability to adopt policies and choices that are binding because they are aimed at achieving the common good on the local, regional and world levels. Among the policies, those regarding global social justice seem most urgent: financial and monetary policies that will not damage the weakest countries; and policies aimed at achieving free and stable markets and a fair distribution of world wealth, which may also derive from unprecedented forms of global fiscal solidarity, which will be dealt with later.On the way to creating a world political Authority, questions of governance (that is, a system of merely horizontal coordination without an authority super partes cannot be separated from those of a shared government (that is, a system which in addition to horizontal coordination establishes an authority super partes) which is functional and proportionate to the gradual development of a global political society.

Is this sound and timely advice, or an example of the Vatican's moral reach exceeding its technical grasp?
