The five rung certificate of deposit ladder is one of the oldest savings strategies in personal finance and it has come back into relevance in 2026 because rates on short term and intermediate CDs are sitting at meaningful spreads above the best high yield savings accounts. The standard structure splits a fixed dollar amount into five equal portions and places each portion into a CD with a different term. A 25,000 dollar ladder might place 5,000 dollars each into a 6 month, 12 month, 18 month, 24 month, and 36 month CD. As each CD matures the proceeds either get spent for a known expense or roll into a new 36 month CD, which builds a ladder where one rung matures every six months and the average yield reflects the current 36 month rate.
CD rates as of this week show a clear curve. The top yielding 6 month CD is paying 4.10 percent at Marcus by Goldman Sachs, the top 12 month is 4.35 percent at Synchrony, the 18 month is 4.45 percent at Sallie Mae, the 24 month is 4.30 percent at Bread Financial, and the 36 month is 4.20 percent at LendingClub. The blended yield across a 25,000 dollar ladder using these rates is approximately 4.28 percent. The best high yield savings account rates this week sit between 3.85 percent and 4.10 percent at Wealthfront, Marcus, and Bask Bank. Short term Treasury bills bought through TreasuryDirect or held through SGOV and BIL exchange traded funds are paying between 4.20 percent and 4.30 percent at the four week and 13 week tenors.
The advantage of the CD ladder against a high yield savings account is yield stickiness. The savings account rate floats with the Federal Reserve target rate and falls quickly when the Fed cuts. A 36 month CD locks the rate for the full term, so a CD purchased today at 4.20 percent will continue to pay that rate even if the Fed cuts the federal funds target by 100 basis points over the next 18 months. CME futures pricing on Wednesday morning implied a 64 percent probability of a 25 basis point reduction at the June 16 to 17 FOMC meeting, with two to three additional cuts priced in by year end 2026.
The advantage of Treasury bills against CDs is liquidity and tax treatment. Treasury bills are exempt from state and local income tax, which matters meaningfully in California, New York, New Jersey, Massachusetts, Oregon, Maryland, and the District of Columbia where the marginal state and local rate ranges from 5.5 to 13.3 percent. CDs have no such exemption. Treasury bill funds including SGOV, BIL, and USFR can be sold any business day with one business day settlement, while CDs typically have an early withdrawal penalty of 90 to 180 days of interest for early redemption.
The advantage of the CD ladder against either alternative is fixed maturity dates aligned with known cash needs. Households saving for a down payment, a major remodel, a vehicle purchase, or a tax payment can ladder maturity dates to match the spending dates and earn meaningfully more than a savings account would pay over the same window. The Federal Deposit Insurance Corporation insurance limit of 250,000 dollars per depositor per institution per ownership category covers CDs the same way it covers savings accounts, so safety is identical for amounts under the cap.
Brokered CDs are the version most large account holders use. These are CDs issued by banks but sold through brokerage platforms including Fidelity, Schwab, and Vanguard. The brokered CD market in 2026 generally offers slightly lower rates than direct bank CDs but allows the holder to sell the CD on the secondary market before maturity, which provides a liquidity option that direct bank CDs do not. Brokered CDs can also be aggregated across many issuing banks within a single brokerage account, which keeps every position under the FDIC insurance cap with a single statement.
The trap to avoid is callable CDs. Some institutions market high stated rates on CDs that include a call option allowing the bank to redeem the CD before maturity at par. The bank will exercise the call when rates fall below the CD rate, which leaves the holder reinvesting at the lower prevailing rate while not having received the rate stickiness benefit that justified the lock up. Read the full disclosure before purchase. Non callable CDs and brokered non callable CDs are the cleaner choice.
The simplest move for a household with cash sitting in checking earning nothing is to start with a basic three rung ladder of 12, 24, and 36 months at three thousand to seven thousand dollars per rung, then add to the ladder as savings accumulate. The yield difference compared to a checking account or even a basic savings account compounds meaningfully over five years, and the discipline of dated maturities tends to keep emergency cash aligned with actual emergencies rather than discretionary spending.
