Savers can still take advantage of the best one-year fixed-rate period with a 365-day savings account yielding 5.78 percent if they sign up this week.

The 365-day notice period account is offered by the savings and investment platform Bloom*, in a deal This is Money has secured for readers through Friday, July 27.

The Prosper account pays a variable rate of interest that is 0.35 per cent above the Bank of England base rate, giving a current gross rate of 5.6 per cent. But because the interest is calculated and compounded daily, the AER is even higher – at 5.78 per cent.

The bill with a notice period of 365 days with an AER of 5.78 percent comes from the savings platform Prosper

This is significantly better than the best one-year fixed rates of Union Bank of India (5.40 percent), followed by Access Bank (5.25 percent).

While savers have to wait 365 days to access their money, they can consider it an unusual alternative for a fixed period of one year by opening an account with Prosper and closing it immediately.

To take advantage of the deal, savers must open a Prosper savings platform account using this This is the link Money and Prosperity* and select it there. (See below for more information.)

Prosper’s 365-day notice account has a minimum balance of £20,000 and a maximum balance of £250,000 and offers FSCS savings protection of up to £85,000 with Santander International, which manages the savings deposits.

One-year fixed-rate accounts peaked at 6.2 per cent last autumn. But rates fell as the Bank of England base rate stood at 5.25 per cent, and the best deals on This is Money’s independent savings tables now pay just over 5 per cent.

A notice period account is a type of savings account that requires you to give your bank a certain number of days’ notice before withdrawing money. In the case of this Prosper deal, a notice period of 365 days is required, which is considerably longer than most accounts.

The best notice period accounts on the market currently are a 5.25 percent 90-day account from Investec and a 5.15 percent 90-day account from BLME.

AER versus gross interest

AER and gross interest are terms that indicate how much interest you can earn on your savings.

AER calculates compound interest (when returns are earned on existing returns), but gross interest does not.

When interest is paid more than once a year, compound interest means that the AER will be higher than the gross interest.

If the interest is paid monthly or daily, the difference between gross and AER can be significant.

Base rate forecasts

Savers should be aware that the base rate is expected to fall and that if cuts do occur, the interest rate on the account will also fall.

The base rate would have to be cut twice by 0.25 percentage points to bring the Prosper deal down to the level of the highest one-year fixed interest rates.

Expectations of rate cuts have been tempered since the start of the year.

According to interest rate forecasts, the Bank of England may not cut rates until September, meaning interest rates will not fall as quickly as previously thought.

If the base rate is lowered to 5 percent, the interest on Prosper’s account will drop to 5.35 percent. If the base rate drops to 4.75 percent, Prosper’s interest will be 5.1 percent, and if it is lowered to 4.5 percent, Prosper’s deal will pay 4.85 percent.
