Portman Building Society is withdrawing its one-year fixed-interest bond because it has been inundated with inquiries.
The bond was launched three weeks ago with an interest rate of 6.5 per cent gross per year.
Portman spokesman Mike Dobson says: "Demand has been extremely heavy and this pressure has forced us to replace the product."
It is being replaced by another One Year Fixed Interest Bond paying 6 per cent gross per year.
The minimum investment is £500.
