Our Expert Opinion on Castle Trust Bank 2 year Fixed Rate e-Saver

Jonny PeaseCo-Founder, DepositScout

Castle Trust Bank's 2 year Fixed Rate e-Saver pays 4.55%, which is 0.80% below the fixed-rate market leader at 5.35%, and sits below the market average, so this is not a rate I would highlight as a standout pick. That said, it does beat CPI inflation of 3.1% by 1.45 percentage points, so your money is at least growing in real terms. The key catch is that access is locked until maturity, with withdrawals only considered in cases of genuine financial hardship. If you want a two-year fix, Kent Reliance's 2 Year Fixed Rate Bond at 4.91% is worth a look instead.
