Whether or not you will still be able to invest in financial instruments registered/listed in the United Kingdom after a ‘no-deal’ Brexit depends on whether the trade in these instruments still complies with the rules in force in the EU after a no-deal Brexit. The answer to this question can differ per instrument. Generally speaking, based on European Mifid II regulations, certain instruments may be traded only on trading platforms authorised for that purpose. After a no-deal Brexit, British trading platforms would be defined as ‘third-country platforms’, for which such authorisation is not necessarily immediately available.
The Brexit could have consequences for certain investments in investment funds if no additional agreements are entered into with the UK. There might also be potential consequences for dual-listed shares, shares quoted on several exchanges. The questions below are based on the assumption of a no-deal hard Brexit.
