Sorry to butt in, but hereās my understanding.
EU customers on the CY platform.
FSCS is bank protection provided by partner institutions. Itās inherited. QMMFs are not banks, hence the risk statements on sign up to use the product.
This is in the risk statement when you sign up to the product. Thereās no free lunches in investing, to access the higher rates you have to be prepared to take on a little risk. QMMFs are pretty well regulated, but a 2008 style crash will hurt an QMMF fund.
