NS&I boosts interest rate for 333,000 Direct ISA customers

More than 333,000 NS&I Direct ISA customers are set to benefit from today, with the interest rate NS&I pays on the account increasing from 2.15% tax-free/AER to 2.40% tax-free/AER.

The increase to the interest rate paid on NS&I’s Direct ISA follows upwards changes made to Premium Bonds, Income Bonds and Direct Saver earlier this year. In February this year, NS&I also brought one-year Guaranteed Growth Bonds and Guaranteed Income Bonds back on sale.

The change made to NS&I’s Direct ISA will ensure that the product is priced appropriately when compared to the rest of the ISA market. It will also help ensure that NS&I continues to balance the interests of savers, taxpayers and the broader financial services sector.
