Moneybox has introduced a Cash ISA featuring an attractive interest rate of 4.75%, which is currently the highest in the market according to Caitlyn Eastell, a Personal Finance Analyst at Moneyfacts. This account, available to new customers, can be opened with a minimum deposit of £500 and allows for transfers. The account permits up to three withdrawals per year without penalty; however, exceeding this limit will reduce the interest rate to 0.75% AER. Additionally, the account includes a 1.30% AER bonus for the first year, prompting savers to reassess their options once this bonus period concludes. Moneybox's offering is noted for its monthly interest payments, appealing to those looking to enhance their income. Other notable ISA products include Plum's Easy Access ISA at 4.60% and Secure Trust Bank's two-year fixed ISA at 4.72%. Money Saving Expert has also recognized Trading 212's easy access Cash ISA as a top choice for new investments, offering a rate of 4.76%.
