Bonds, CDs, and Treasuries: Building Safe Income in Retirement
Treasuries, CDs, and bonds each play a different role in a retirement income plan. Learn how laddering works, where reinvestment risk hides, and how the safe side of your portfolio fits.
A retired couple in Gilbert came to see me last year, rattled. They'd spent forty years building a comfortable nest egg, and after a bumpy stretch in the markets, the husband said something I hear constantly: "I don't want to gamble with money we can't afford to lose. I just want some of this to be safe." That's a completely reasonable instinct. The question isn't whether you should hold safe, income-producing assets in retirement, you almost certainly should. The question is which ones, how they fit together, and where the hidden tradeoffs hide.
So let's talk plainly about bonds, CDs, and Treasuries, what each one actually does, and how they fit into a real retirement income plan.
The Job These Assets Do in Your Plan
Before we get into the specifics, it helps to step back. In retirement, your portfolio has two jobs that pull in opposite directions. It needs to grow enough to outpace inflation over a 30-year retirement, and it needs to provide stable income you can count on regardless of what the stock market is doing this year. Stocks handle the first job. Bonds, CDs, and Treasuries are the workhorses of the second. They're not where your big growth comes from, they're where your stability and predictability come from.
A common approach is to keep a few years of spending in safe, stable assets so you're never forced to sell stocks during a downturn to pay your bills. When the market drops, you spend from the safe bucket and give your stocks time to recover. That's the role these instruments play.
Treasuries: The Foundation
U.S. Treasury securities are backed by the full faith and credit of the federal government, which makes them about as close to "no credit risk" as you can get. They come in a few flavors: T-bills (short term, under a year), T-notes (2 to 10 years), and T-bonds (longer). For Arizona retirees, Treasuries carry a particularly nice perk: the interest is exempt from state income tax, which matters even though Arizona's income tax is relatively modest.
You can buy them directly or hold them through funds. The tradeoff with Treasuries is that their safety usually comes with lower yields than corporate bonds. You're trading some income for the peace of mind of essentially zero default risk, which for the "safe" portion of a retirement portfolio is often exactly the trade you want to make.
CDs: Simple, Insured, and Predictable
Certificates of deposit are about as straightforward as it gets. You hand the bank money for a set term, they pay you a fixed rate, and FDIC insurance covers up to $250,000 per depositor, per bank, per ownership category. For someone who values knowing the exact dollar amount they'll have on a specific date, CDs are appealing.
Two cautions. First, the FDIC limit means large savers need to spread money across multiple banks (or use brokered CDs) to stay fully insured. Second, breaking a CD early usually triggers a penalty, so the money you put in should genuinely be money you won't need until the CD matures. CDs are a fine tool, but they're a parking spot, not a growth engine.
Bonds: Income With a Few More Moving Parts
"Bonds" is a broad bucket, corporate bonds, municipal bonds, agency bonds, and more. They generally pay higher yields than Treasuries because you're taking on some credit risk (the issuer could default) and interest-rate risk (bond prices fall when rates rise). Municipal bonds deserve a mention for higher-income retirees, since their interest is often federally tax-free, which can make their after-tax yield surprisingly competitive.
The key thing to understand is that bond prices move opposite to interest rates. If you hold an individual bond to maturity, those price swings don't really hurt you, you get your principal back at the end. But if you hold bond funds, the value fluctuates daily, and that surprises people who thought "bonds" meant "no risk."
Ladders and the Reinvestment Question
Here's where a little strategy goes a long way. A ladder means buying bonds, CDs, or Treasuries that mature at staggered intervals, say, something coming due every year for the next five to ten years. As each rung matures, you either spend that money or reinvest it at whatever rates are available then.
Laddering solves two problems at once. It gives you a predictable stream of maturing cash to live on, and it spreads out reinvestment risk, the danger that you lock everything in at one rate right before rates change. If you put your entire safe bucket into a single 5-year CD and rates jump the next year, you're stuck. With a ladder, only a portion comes due at any given time, so you're constantly reinvesting at fresh rates rather than betting everything on one moment.

Where This Fits in the Bigger Picture
The mistake I see most often isn't choosing the "wrong" safe asset, it's having too much or too little of them, and not knowing why. A retiree terrified of the market might dump everything into CDs and Treasuries, then watch inflation quietly erode their purchasing power over 25 years. Another might be so growth-focused that a market drop forces them to sell stocks at the worst possible time. The right balance depends on your spending needs, your other income sources like Social Security, and how much volatility you can genuinely stomach.
This is where a coordinated plan matters. The amount you keep in safe income assets should connect to your overall risk tolerance and withdrawal strategy, not be chosen in isolation. Our portfolio risk alignment analyzer can help you see whether your current mix actually matches the retirement you're picturing. And because these decisions are deeply personal, a fee-only advisor who isn't earning a commission on any product can help you choose what's genuinely best rather than what pays them most.
The Bottom Line
Bonds, CDs, and Treasuries each have a distinct role in building reliable retirement income, and used together, often in a ladder, they let you ride out market storms without selling your growth assets at the wrong time. The art is fitting them into a plan that's calibrated to your spending and risk tolerance.
