The Sage and his buddy, Hines, insist that folks really would just love to invest, through bonds, in the green revolution.
However, experts warned the bonds would return £700 less than rival accounts. Investing £20,000 in the market’s top paying three-year fixed-rate bond, the 1.81pc offered by JN Bank, would earn £232 more in interest in the first year than NS&I’s green bond.
Martin Lewis of MoneySavingExpert, a consumer advice website, said: “The Chancellor must really hope that the nation is wearing green trousers as the rate being offered is pants.
“This is quite simply not an account that those whose focus is maximising interest will look at – it’s likely only something those willing to sacrifice substantial interest in order to support what they hope will be green causes are likely to consider.”
So we’ll find out, won’t we? After all, no economic theory survives first contact with the marketplace unscathed.
