According to Bloomberg, the Treasury Department’s undersecretary for terrorism and financial intelligence, Sigal Mandelker, sent a letter on May 7 warning that Instex, the European SPV to sustain trade with Tehran, and anyone associated with it could be barred from the U.S. financial system if it goes into effect. As a reminder, last September, in order to maintain a financial relationship with Iran that can not be vetoed by the US, Europe unveiled a “Special Purpose Vehicle” to bypass SWIFT. Back then we predicted that Washington would not be too delighted with this development seeking to undermine the dollar’s reserve status. We were right.
