A CD ladder in 2026 beats Treasury bonds only when the certificates are bought near the top of the market, not at the average. The FDIC's national average rates as of August 17, 2026 were 1.14% for a 3-month CD, 1.71% for 12 months and 1.36% for 60 months, while its national rate caps, which track the best of the market, were 5.35%, 5.65% and 6.09% for the same terms [1]. Treasury yields on August 17 were 4.00% for one year, 4.19% for two, 4.38% for five and 4.54% for ten [2]. A saver who accepts the average CD gives up roughly 2.3 to 3.0 percentage points a year versus a Treasury; a saver who shops near the cap can earn more than a Treasury while keeping FDIC insurance. This article explains how a ladder works, what it pays today and where the break-even lies.
What a CD ladder is and how it works
A ladder splits a lump sum across certificates of deposit with staggered maturities. A classic five-rung ladder on $100,000 places $20,000 each in 1-, 2-, 3-, 4- and 5-year CDs. When the 1-year CD matures, the proceeds buy a new 5-year CD, and so on, so that after four years every rung is a 5-year certificate and one matures every year. The structure gives the average yield of the longer terms with the liquidity of an annual maturity, and it removes the need to guess the direction of interest rates.
- Decide the total and the number of rungs; equal amounts keep the math simple.
- Buy one CD per rung with the best insured rate available for each term, staying under $250,000 per depositor per bank.
- At each maturity, reinvest in the longest rung unless the cash is needed.
- Track the ladder next to a Treasury alternative each year; if the CD rate falls below the comparable Treasury, roll into the Treasury instead.
CD rates in August 2026 next to Treasury yields
The FDIC publishes both the deposit-weighted national average and a cap that equals the higher of the average plus 75 basis points or 120% of the comparable Treasury yield plus 75 basis points [1]. The cap is a regulatory ceiling for weak banks, but it is also a useful marker of the upper end of advertised rates, because it is built from the Treasury curve.
| Term | National average CD | National rate cap | Treasury yield (Aug 17, 2026) |
|---|---|---|---|
| 3 months | 1.14% | 5.35% | 3.82% |
| 6 months | 1.41% | 5.53% | 3.95% |
| 12 months | 1.71% | 5.65% | 4.00% |
| 24 months | 1.57% | 5.89% | 4.19% |
| 36 months | 1.34% | 5.96% | 4.25% |
| 60 months | 1.36% | 6.09% | 4.38% |
Two features stand out. First, the average CD curve is inverted: 12-month CDs pay 1.71% while 60-month CDs pay 1.36%, so banks on average are not paying savers to lock money up for longer [1]. Second, the Treasury curve is upward sloping from 3.82% at three months to 4.54% at ten years, and the 30-year bond yielded 5.28% on the same day [2]. A saver building a ladder at average CD rates is accepting less than half the Treasury yield at every rung.
The rate backdrop
The Federal Reserve kept its target range at 3.50% to 3.75% on July 29, 2026 and said inflation remains elevated relative to its 2% goal [3]. The effective federal funds rate averaged 3.63% in July, according to DataPorium's economic metrics [4]. Short CD and bill yields sit just above that rate; the extra 0.4 to 0.9 percentage points at 5 to 10 years on Treasuries is compensation for locking in.
When a CD ladder beats bonds, and when it does not
The comparison rests on four points.
- Yield. A CD beats a Treasury of the same term only if its rate is higher after tax. CD interest is fully taxable at federal and state level; Treasury interest is exempt from state and local tax. A 4.38% Treasury for a saver with a 5% state tax rate is worth about 4.61% in CD terms.
- Liquidity. A Treasury can be sold any business day at the market price. A CD is redeemed before maturity only with an early withdrawal penalty, usually several months of interest. The ladder structure exists to soften that constraint.
- Rate risk. If rates rise, a Treasury sold early loses value while a CD merely forfeits some interest; if rates fall, both lock in the higher yield. For a saver who might need the money, the CD penalty is a known cost and the Treasury's price move is not.
- Credit. Both are backed by the U.S. government, one directly and one through FDIC insurance up to $250,000 per depositor per bank. Neither adds credit risk within the limits.
The practical rule: at the FDIC average, a ladder loses to Treasuries at every maturity and the shortfall on $100,000 is roughly $2,300 to $3,000 a year. At rates near the cap, which some online banks and credit unions advertise, a ladder can outpace the Treasury curve by 1 to 1.5 percentage points and remains fully insured. Between those poles, the state tax exemption and the liquidity of Treasuries usually decide it.
A ladder in a saving-and-investing plan
A ladder is a tool for money with a known date: a house down payment in two years, tuition in four, or the first five years of retirement spending. It is not a substitute for long-term investing, because 4% to 6% nominal yields barely clear the 3.3% annual CPI inflation recorded for July 2026 in DataPorium's CPI series [4] once taxes are paid. Savers who take responsibility for their own outcomes tend to hold three layers: a money fund or bill for immediate needs, a ladder for dated needs, and diversified stocks and bonds for everything beyond five years. The ladder's job is to make sure the dated needs never force a sale of the long-term layer at a bad time.
A CD ladder is worth building in 2026 only at rates near the FDIC's 5.65% to 6.09% caps; at the 1.36% to 1.71% national averages, Treasuries paying 4.00% to 4.54% are the better insured-equivalent choice.
Key takeaways
- FDIC national average CD rates as of August 17, 2026: 1.71% for 12 months and 1.36% for 60 months; national rate caps: 5.65% and 6.09% [1].
- Treasury yields on August 17: 4.00% at one year, 4.19% at two, 4.38% at five, 4.54% at ten and 5.28% at thirty [2].
- The average CD curve is inverted, so long CDs at average rates pay less than short ones; the Treasury curve slopes upward.
- Treasury interest is exempt from state tax and Treasuries are liquid; CDs are FDIC insured and carry a fixed early withdrawal penalty.
- With the Fed's range at 3.50% to 3.75% and CPI inflation at 3.3%, a ladder protects dated cash needs but does not replace long-term investing [3][4].
Frequently asked questions
Are CD ladders worth it in 2026?
Only at rates well above the FDIC national averages of 1.14% to 1.71%. Treasuries paid 4.00% to 4.54% from one to ten years on August 17, 2026, so a ladder needs rates near the FDIC caps of 5.35% to 6.09% to win [1][2].
What is the best CD term right now?
On average rates, 12 months paid the most at 1.71%, more than the 60-month average of 1.36%. Among top-of-market rates the FDIC caps rise with term, from 5.35% at three months to 6.09% at five years [1].
Is a 5-year CD better than a 5-year Treasury?
The 5-year Treasury yielded 4.38% on August 17, 2026 and is exempt from state tax, so a 5-year CD would need to pay more than about 4.6% for a saver in a 5% state bracket to come out ahead [2].
How much money do I need to start a CD ladder?
There is no set minimum; many banks accept $500 to $1,000 per CD, so a five-rung ladder can start at $2,500 to $5,000. Larger balances should stay under $250,000 per bank to remain fully insured.
