Hello,
My feeling is that this increased tax is designed to help push down the net return on cash savings, to help encourage spending or debt reduction ....
Debt reduction is now the interesting thing. With interest rates so low and the Government taking nearly half of interest earned, for those with mortgages, it is almost a no-brainer to now overpay the mortgage from savings or make lump-sum contributions.
The difference between mortgage rates and net savings rates is now quite disproportionate...
