Would it make sense to hold cash reserve as a Cash ISA or Cash in a Stocks ISA (with Trading 212) - I am looking at about £150k I have in other ISAs - trying to consolidate accounts as I am c1year from retirement.
In a Cash ISA, your cash is allocated to several banks, at a 3.85% interest rate with zero risk.
In a Stock ISA, small portion of cash will be allocated in banks. However, a majority of your cash will be allocated in Qualified Money Making Funds, these are low risk but allows you to gain 4.05% interest on your cash.
I personally store my cash in Stock ISA for the higher interest. You can withdraw, invest or transfer with no delays.
