The recent dip in interest for fixed-rate cash ISAs may come as a surprise given the rising competitive landscape. However, new data from Moneyfacts reveals that the proportion of savers searching for these accounts via its platform decreased from 26% in April to 19% in May, despite average rates on one-year fixes climbing to 4.25% AER and exceeding £8,000 in interest.
Contrastingly, demand for instant-access ISAs surged during the same period, rising from 24% to approximately 32%. Rachel Springall, a finance expert at Moneyfacts, suggests that market volatility and anticipation of a potential base rate rise may be contributing to savers' reluctance to commit to fixed rates. Furthermore, the typical surge in demand for ISA products at the start of the new tax year in April might have contributed to the subsequent dip in May.
The impending reduction in tax-free savings allowances from £20,000 to £12,000 in April 2027 presents a compelling argument for savers to secure fixed-rate cash ISAs for longer terms. This strategic move could effectively defer the impact of these new rules until their account matures in 2031, allowing them to continue benefiting from the current tax-free allowance.
Current market conditions also present an opportune moment for savers, with average interest rates on one-year fixed cash ISAs climbing to 4.25% AER and products with terms exceeding one year seeing average rates increase from 4.14% to 4.22%. For instance, a two-year fixed cash ISA is currently offering rates as high as 4.72% AER, significantly outperforming the best instant-access deals, which stand around 4.25%. This differential highlights the potential for savers to earn higher returns by fixing their money, alongside the benefit of shielding their savings from future regulatory changes.
A four-year fix from one provider offers 4% AER, with most top fixed-rate options surpassing the best instant-access rates, making them an attractive consideration for those planning for the long term. With £8,000 still available in the current annual ISA allowance to be invested in a Stocks and Shares ISA, savvy savers may opt to split their allocation between cash and equity-based ISAs to maximise returns and mitigate potential risks.
