If Reeves is going to tinker around with cash ISAs then she also needs to take a good, hard look at Premium Bonds.
Introduced in 1956 as a way to encourage post war savings and support the economy (by loaning the Government money) there is no need for them and they are expensive.
The Government pays 5 billion a year in interest as prize money but the vast majority of bonds win absolutely nothing. The minimum investment is £25 which gives someone 25 chances a month.
The odds of any £25 holding winning a million pounds are one in 2.6 billion. You may as well stand in the middle of Birmingham or Manchester and yell, It’ll be me!!!
Each month around 600,000 bonds do win something, usually £25, but £129 billion bonds win absolutely nothing. (MSE numbers from 2024).
Compare someone who invests in cash ISAs because they need guaranteed income. £50,000, possibly accumulated over many years,now paying 5% will yield £2,500 from a bank or building society - enough to pay council tax for most and a few other bills.
Contrast, someone with PBs who can afford have £50,000 of cash sitting there with no guarantee of a return. But the Government still has to pay interest on the total invested. It is just borrowing money from one person and paying the interest to a machine-selected few. Moreover, couples can have £100,000 sitting there. Of course, some will win a few prizes but there is no guarantee.
I would have no objection to having say a cap of £100,000 on cash ISAs but if Reeves is going to argue that cash ISAs are dead money (I think it was Emma Reynolds who did argue this) then PBs are even deader and a ridiculously unfair way of distributing income.
Of course, it would have to physically repay the 130 billion but could fund it with a gilt issue paying 4% that others would buy. Gilts are a safe bet in these dangerous times. Many people are already moving their money into them.
