Santander members Alliance and Leicester and Abbey have teamed up to provide new guaranteed investment funds for new and existing customers with a guaranteed return of ten per cent.
Customers of the Guaranteed Growth Plan option can choose between a stock market-based investment, receiving half of the FTSE 100 up to 25 per cent, or a house price-based version, getting returns based on half of the growth of the housing market .
The banks have also launched a Guaranteed Capital Plus option and with a minimum investment of £1,500 customers receive 30 per cent if the FTSE 100 has experienced any growth or 0.50 per cent if it has not.
Pak Chan, head of investments at Abbey, said: "For savers looking for exposure to equities or the UK housing market, but without putting their capital at risk, the [investments] could be a great choice, especially given the recent falls in both areas."
Scottish Widows recently launched its Capital Protection Fund 10 investment scheme which guarantees a return based on the performance of the FTSE 100.
