How will Brexit affect your investment and pension portfolio?

Where are we just now on the Brexit timeline?

  • It is four and a half years since the United Kingdom voted to leave the European Union.
  • The United Kingdom left the EU in January this year and is currently in a transition period which ends on 31st December 2020.
  • What happens from 1st January onwards, depends on the outcome of the ongoing negotiations.

What does this mean for our clients investment and pension portfolios?

Whatever happens, the impact on our clients’ portfolios will be extremely small.

Why is that?

The UK stock and bond markets only make up 5% of global markets. Therefore, only 5% of our portfolios are invested in the UK; the remaining 95% is invested all over the world, according to the proportion of global markets each country makes up.

What should you do?

Find out how much of your investments and pensions are invested in the UK.

There is no reliable way of predicting whether UK markets will go up or down in 2021. We don’t know how Brexit negotiations will conclude, what the ongoing impact of COVID-19 will be or what other unexpected events will occur in the months ahead.

In the absence of a crystal ball, the most sensible approach, which is supported by decades of academic research, is to invest in a globally diversified portfolio. That means holding around 5% in the UK.

If you aren’t sure how to find out how much you have invested in the UK, please get in touch as we are currently offering our Second Opinion Service free of charge. This service involves a sense-check of your existing investments and pensions to ensure they remain fit for purpose.
