In a stunning vote of "no confidence" in the US monopoly over global payment infrastructure, one month ago Germany's foreign minister Heiko Maas called for the creation of a new payments system independent of the US that would allow Brussels to be independent in its financial operations from Washington and as a means of rescuing the nuclear deal between Iran and the west.

Writing in the German daily Handelsblatt, Maas said "Europe should not allow the US to act over our heads and at our expense. For that reason it's essential that we strengthen European autonomy by establishing payment channels that are independent of the US, creating a European Monetary Fund and building up an independent Swift system," he wrote.
