Our Expert Opinion on Cynergy Bank 1 Year Fixed Rate Bond

Jan WatermannCo-Founder, DepositScout

Cynergy Bank's 1 Year Fixed Rate Bond pays 5.05%, which sits near the market average for fixed-rate bonds but is 0.30% behind the current market leader at 5.35%, so it is a reasonable but not standout option. That said, 5.05% does beat August 2026 CPI of 3.1% by 1.95%, meaning your money grows in real terms. The main catch is the usual one for fixed bonds: once the 14-day funding window closes, you cannot access your money until maturity, so only commit funds you will not need. You need at least £1,000 to open, and the account accepts up to £1,000,000.
