- NS&I Green Savings Bonds Issue 4 pays 4.20 per cent
- Savings account might appeal to ethical and sustainable savers
- Only two other "green" accounts pay a higher rate
National Savings & Investments (NS&I) has launched a fourth issue of its three-year Green Savings Bonds as Britain's best known savings institution tries to reinvigorate demand for its newest account.
The 4.20 per cent interest rate puts the latest issue towards the top end of the three-year deals market. It is the third time NS&I has increased the rate since it launched in 2021.
