Inflation will reduce the real value of savings

[The Prophet]

Inflation at the present rate 5.2% is eating into the real buying power of your savings.
It is essential to get the best interest rates you can.
Leaving your cash in an account with a pitiful interest rate will mean your savings will halve in real terms in just 12 years with the current rate of inflation!

[Sadie20]

There are hardly any accounts where the interest you get is enough to beat the effects of inflation.
