Our Expert Opinion on Monument Bank 6 Month Fixed Term Deposit

Jan WatermannCo-Founder, DepositScout

Monument Bank's 6 Month Fixed Term Deposit pays 3.75%, which sits below the market average for fixed-rate accounts and 1.62% behind the category leader at 5.37%. It does beat CPI inflation of 3.1% by 0.65%, so your money holds real value, but the rate is hard to justify given that alternatives like Cynergy Bank's 6 Month Fixed Rate Bond offer 4.57% with a far lower minimum. The £25,000 floor makes this account one for savers with a meaningful lump sum, and the money is fully locked away until maturity with no access at all.
