Frequently Asked Questions
How does rolling a CD ladder work? ▼
When your 6-month CD matures, you reinvest those funds into a new 3-year CD. As each subsequent tranche matures, you reinvest it into a 3-year CD, eventually creating a portfolio where 3-year rates mature every 6 months.
What is the main benefit of a CD ladder over a single CD? ▼
Flexibility and interest rate hedging. You avoid locking all your money at a single interest rate and have cash maturing regularly if you need liquidity.
