If you want a safe place for your cash that pays more than a regular savings account, a high‑yield certificate of deposit (CD) could be the answer. Unlike a checking or everyday savings account, a CD locks your money for a set period—anywhere from a few months to several years—in exchange for a guaranteed interest rate.
What makes a CD “high‑yield” is the rate. In 2025 many banks are offering double‑digit APYs on short‑term CDs, which can outpace the 0.5‑1% you see on most savings accounts. The extra earnings come from the fact that the bank knows it can use your funds for a fixed time, so it rewards you for the commitment.
First, the rate is fixed. No surprise drops when the market shifts. Second, the interest compounds regularly—usually daily or monthly—so your money grows faster. Finally, your principal is FDIC‑insured up to £85,000, so you’re protected if the bank fails.
That said, the trade‑off is liquidity. If you need the cash before the CD matures, you’ll face an early‑withdrawal penalty, often equal to a few months’ interest. For many people the penalty is worth the higher rate, especially if they can match the CD term to a known future expense.
Start by mapping out when you’ll need the money. If you have a wedding or a house down‑payment in 18 months, look for an 18‑month CD. A “CD ladder” strategy—splitting your cash across several CDs with different maturities—lets you capture higher rates while keeping some funds accessible each year.
Next, compare the APY, not just the headline rate. Some banks quote a high rate but add fees that eat into earnings. Check the annual percentage yield (APY) because it reflects compounding.
Don’t forget tax. CD interest is taxable as regular income, so the after‑tax return may be lower than the quoted APY. If you’re in a high tax bracket, a tax‑advantaged account like an ISA (if you’re in the UK) might be a better fit.
Finally, read the fine print. Look for hidden early‑withdrawal fees, minimum deposit requirements, and whether the bank allows you to add more money after opening the CD.
Putting it together, a high‑yield CD works best when you have a clear timeline, don’t need immediate access, and want a guaranteed return. Use the ladder approach to keep some cash liquid, and always compare APYs across banks before you lock in.
