A junior equity analyst told CNBC via email that Brexit is a concern on a professional basis.

“Firms will consequently incur monetary costs (given that the UK will have to renegotiate trade agreements with the EU and other global partners) and at the very least, a large shadow has been cast over the short- and medium-term investment horizons. Even if we were to assume that labor was cheaper and more efficient in the UK compared to mainland Europe, why would a company (large or small) invest in a new office or factory in the UK without knowing what types of restrictions will be imposed on its products when sold/shipped overseas? I believe that this will significantly reduce the employment prospects of current and future generations with few, if any, positive impacts for average UK citizen. This obviously leads to a major personal concern as my wellbeing in this country, as for many others, is largely dependent on my ability to be employed,” he said.

The euro zone economist surveyed is from Denmark but works and lives in the U.K. At the moment, he does not plan on applying for U.K. citizenship.

“I will reevaluate when I get my tax information,” he said.

“People would be lying if they say they aren’t worried about Brexit. No matter what, our (EU citizens) rights will be diminished,” he added, acknowledging that he is in an “easy” situation. “I make money, I’m clean, I’d be allowed to stay in 5 minutes (if he had to apply for a visa),” he said.
