"Many financial firms in London claim to be looking to move to Frankfurt or Paris with BREXIT. They are going to have a very rude awakening. The proposition to demand all euro clearing takes place inside the EU will be the death of Europe – not the rebirth. The dominating position in Brussels among the majority is control the financial markets to prevent any free market movement against the designs of the EU Commission. Additionally, this position of draconian absolute dictatorial control over European markets includes a pan-European freezing of all bank accounts in the event of an impending banking crisis. The EU Commission is deeply concerned what happens when the EU stops its life-support for Eurozone government debt. They are actually considering the way in which multi-day cash disbursements can be practically implemented in order to resolve emergency measures for banks. Their plan is looking at a prolonged banking and financial crisis that would be 20 to 30 days in duration. If government debt crashes with rising rates, then the reserves of banks will decline and this could result in a banking crisis unleashed when the EU stops its life-support program."
