An executive at the Financial Conduct Authority (FCA) said the watchdog will “act” if financial institutions wrongly deny politicians or their families access to services.
Writing in the Telegraph, FCA executive director Sarah Pritchard said they are reviewing whether financial institutions are being “proportionate” in their risk assessments of politically exposed persons (PEPs).
Ms Pritchard said while it is necessary for those in power to be asked for more information than others about sources of wealth, it needs to be an “appropriate level of inquiry”.
“(It) should not feel like the financial equivalent of someone rifling through your bin,” she said.
“We have heard that often it has, particularly for the families of political figures.
“If we find that banks and others are more tick-box than risk-based, we will act. Because proportionate additional financial scrutiny should not make it harder than it needs to be to take part in public life.”
In late June, former leader of the UK Independence Party Nigel Farage had his Coutts bank accounts closed and said he was refused accounts with other banks as a result of his political views.
This resulted in Dame Alison Rose, the CEO of NatWest, the company that owns Coutts, stepping down from her role.
The scandal brought on calls from the Treasury and ministers for the FCA to conduct a review into whether financial institutions are meeting their guidance over the treatment of PEPs and whether that guidance needs to be updated.
Ms Pritchard said the FCA are conducting a review focusing on how “firms are applying the definition of PEPs to individuals” and “checking that firms are being proportionate in their risk assessments of UK PEPs”.
“This sets out that banks and others must be proportionate – with greater scrutiny on those who pose the greatest threat. And we have been clear that UK public figures should generally be considered low risk,” Ms Pritchard said.
Ms Pritchard added that the aims of the review are to keep the “system clean” but not deny PEPs the access to financial products and “services necessary for everyday life”.
