Is Monzo good for ethical investors?

As Monzo only offers three funds, it's easier to find out how ethical they are.

At the time of writing, the BlackRock funds available aim to reduce carbon emissions by 30% compared to equivalent portfolios, and invest at least 80% of their government bonds with countries who have an ESG (ethical, social and governance) rating of BB or higher (ie not the two lowest ratings of CCC or B). 

You cannot choose to avoid certain industries or invest exclusively towards a positive impact.

Is your money safe with Monzo?

Monzo is regulated by the Financial Conduct Authority (FCA) and covered by the Financial Services Compensation Scheme (FSCS).

When you invest with an investment platform that's registered with the FCA, your money will be ring-fenced and should be returned if a company goes bust, without you having to wait alongside other creditors.

If ring-fencing failed, you would be compensated by the FSCS.

The FSCS will cover up to £85,000 of investments per person, per platform. You can claim for free online at fscs.org.uk. There's no reason to use a claims-management company.

You won't be compensated for investments falling in value, or if a company in which you hold shares goes bust, unless this poor performance resulted from bad advice given by a regulated independent financial advisor that has since gone bust.
