CDs vs Bonds vs Treasuries 2026: Which Earns You More?

If you have cash sitting in a checking account earning next to nothing, you already know you need a better option. But when you start comparing CDs vs bonds vs Treasuries 2026 choices, the differences can feel murky. All three are fixed-income products, all three pay interest, and all three sound "safe." The reality is more nuanced. Treasuries, specifically short-term T-bills, currently yield around 4.40% for a 12-month term, and that interest is exempt from state and local income tax. Top 12-month CDs pay roughly …, fully taxable at every level. Investment-grade corporate bonds offer 5.0–5.8%, but you accept real credit risk and price volatility in exchange. The right pick depends on your state tax rate, how soon you might need the money, whether you have a brokerage account, and how much you are putting to work. This guide lays out the after-tax math, shows you exactly where each product wins and loses, and gives you a step-by-step framework so you can move your cash into the right vehicle today. If you're deciding between these three options, or wondering whether a high-yield savings account belongs in the mix, read on.

CDs vs Bonds vs Treasuries 2026: Side-by-Side Comparison

The table below captures the structural differences across the three products as of June 2026. Keep it bookmarked: the operational details matter as much as the headline yield.

CD rates in this comparison were last verified recently.

CD yields follow the fed funds path (currently 4.00%) with a lag of weeks to months. That means the gap between CDs and Treasuries widens and narrows as banks reprice. Here is how CD rates have moved recently:

This is especially important if you're someone who checks rates once and then forgets. A CD that looked competitive in January may trail Treasuries by 0.2 points by June because the bank was slow to adjust.

The Case for Treasuries

Treasuries have three structural advantages worth understanding, but whether they're actually the better pick right now depends on your state tax bracket: check the live CD and Treasury rates in the table above, since the pretax gap between them moves as banks reprice, and it can currently favor either side depending on where each stands. A fourth Treasury-only option, a TIPS, trades the higher nominal yield for a fixed return above whatever inflation turns out to be; see how today's 10-year TIPS real yield compares to the nominal Treasury for the full breakeven math.

State-tax exemption

Treasury interest is exempt from state and local income taxes. For high-tax-state residents, this is the single biggest lever. Consider a resident of California with a 13.3% state marginal rate. On a 4.40% T-bill, the state-tax exemption adds roughly 0.55 percentage points of effective yield compared to an identically-yielding CD (at today's Treasury yield — this scales with the rate, so recompute it as rates move).

For example, consider Maria, a New York City freelancer with $75,000 in short-term savings. She faces a combined state-plus-city marginal rate of about 12.7%. If she puts that $75K into a 12-month T-bill at 4.40% instead of a top CD at …, her state-tax exemption alone is worth roughly $391 (at today's Treasury yield times her marginal rate), even though the CD's higher nominal rate today partly offsets that advantage — run both numbers together with the CD calculator rather than relying on either in isolation.

No FDIC cap

FDIC insurance stops at $250K per depositor per institution. If you have $500K in CDs, you need two banks. Treasuries carry the full backing of the U.S. government with no dollar limit. A $500K Treasury position has the same backing as a $5,000 one. For balances above the FDIC threshold, Treasuries remove an entire layer of account management. Learn more about FDIC deposit insurance limits on fdic.gov.

Better mid-term liquidity than CDs

CDs charge 3–6 months of interest as an early-withdrawal penalty. T-bills can be sold on the secondary market at current prices, usually close to face value when held near maturity, with limited price risk on short-duration instruments. If you're a retiree who might need to tap funds for an unexpected medical bill, this flexibility matters.

When CDs Win Over Treasuries and Bonds

CDs make sense in specific, well-defined scenarios. Assuming Treasuries automatically win because of the tax exemption would be a mistake — check the live rate table above, since top CDs are currently ahead of Treasuries on pretax yield, not behind.

Operational simplicity. Opening a Marcus CD is one click if you already have a Marcus account. No new TreasuryDirect account, no brokerage research. If you already bank at one of the top CD providers, the friction savings are real.

No-state-tax states. In Texas, Florida, Washington, Tennessee, and similar states, the state-tax exemption is worth zero. CDs and Treasuries compete purely on nominal yield, and CDs occasionally win, especially during promotional windows.

Promotional CD rates. Banks periodically run promotional CDs above market. A 13-month promo CD at 4.50% beats a 4.40% T-bill on pure yield, even before tax considerations. Check the live CD rate table before assuming Treasuries always win.

No brokerage account. Buying Treasuries efficiently requires a brokerage (Fidelity, Schwab, Vanguard) or a TreasuryDirect.gov account. The friction of opening one may outweigh a 0.1-point yield difference on a $10K balance.

When Corporate Bonds Win

Investment-grade corporate bonds (BBB– or higher) pay 5–6% on 1-year maturities as of June 2026, a clear step up from both CDs and Treasuries. But that extra yield comes with trade-offs.

Default rates by rating (historical averages)

For AAA/AA-rated 1-year corporates at 5.2%, the credit-loss-adjusted yield is roughly 5.1%, still well above the current 1-year Treasury at 4.40%. Historical default data sourced from S&P Global and Federal Reserve research.

Bond mutual funds and ETFs like Vanguard Total Bond (BND), iShares Aggregate Bond (AGG), or SPDR Short-Term Corporate (SPSB) give diversified exposure without individual credit-picking. Our best CD rates guide explains when locking into a CD ladder may be a simpler alternative.

Pros of corporate bonds

• Highest nominal yield of the three options (5–6% on investment-grade)
• Wide selection of maturities and issuers
• Bond ETFs offer instant diversification and daily liquidity
• Suitable for income-focused portfolios (retirees, conservative allocation)

Cons of corporate bonds

• Real credit risk: even investment-grade issuers can be downgraded or default
• Price volatility if you sell before maturity
• Taxable at both federal and state levels
• Individual bonds often require $1,000–$10,000 minimums
• Concentrated credit risk if you hold only one or two issuers on a small balance

Dollar-Impact Ladder: How Much You Actually Earn

Raw yields are abstract. Here is what each option puts in your pocket on common balance tiers over 12 months, assuming a 33% federal rate and a 10% state rate (representative of states like New York or Illinois), using today's rates: a top CD at 4.40%, a 1-year Treasury at 4.10%, and an AAA corporate bond at 5.2%. Recompute this with the live rates above if you're reading this later, since the gap moves as banks reprice.

At today's rates, the Treasury-vs-CD gap grows with balance, but it's driven entirely by the tax exemption, not a pretax yield edge — the CD actually pays more before tax right now. At $100K in a 10% state-tax bracket, that nets a high-tax-state resident roughly $239 more per year in the Treasury. The corporate bond's after-tax edge over the Treasury is roughly $217 at $100K, and it comes with credit risk attached.

If you're a no-state-tax resident (Texas, Florida), the Treasury and CD columns converge. Run your own numbers with our HYSA savings calculator to see the exact impact at your balance and tax bracket.

Marketing-Hook Deconstruction: "Earn 4.50%, Limited Time!"

Banks love promotional CD rates. You have probably seen ads shouting "4.50% APY, 13-month special!" The hook works because it anchors your attention on a number that beats the current top standard CD at ….

Here is what the fine print usually hides:

• Short promo window. The rate may apply only if you open within a two-week window. Miss it and you get the standard rate.
• One-time only. When the promo CD matures, your money rolls into a standard CD at a much lower rate unless you actively move it.
• Early-withdrawal penalty. If you need the money at month 8, you forfeit 3–6 months of interest, potentially wiping out the entire rate advantage.
• Opportunity cost. While your money is locked, Treasury yields may rise. A T-bill buyer can reinvest quarterly; a CD holder cannot.

Promotional CDs can still be worth grabbing, but only if you treat them as tactical windows, not a permanent strategy. Compare the promo rate against the current T-bill yield at 4.40%, factor in your state tax, and only lock up money you truly will not need before maturity. Our HYSA vs CD guide walks through the liquidity math in more detail.

How to Choose Between CDs, Bonds, and Treasuries

Follow these steps to make your decision in minutes, not hours.

1. Check your state tax rate. The exemption only gives Treasuries an edge if it's large enough to overcome the current pretax CD-vs-Treasury gap — check the live table above for that gap, then multiply your state marginal rate by the Treasury yield to see whether it clears that gap. High-tax states like California, New York, and New Jersey typically clear it; lower-tax states with an income tax (Massachusetts, Illinois, and similar) may not, depending on how wide the pretax gap is that day. If you live in Texas, Florida, Washington, or Tennessee, the state-tax advantage is zero, so skip to step 2.
2. Determine your time horizon. Money you might need within 3 months belongs in a high-yield savings account, not a CD or Treasury. Money you can lock for 6–18 months is ideal for T-bills or CDs. Money you will not touch for 2+ years can include corporate bond funds.
3. Check whether you have a brokerage account. If yes, buying T-bills through Fidelity, Schwab, or Vanguard is straightforward and usually better than TreasuryDirect.gov. If no, a top-rate CD at your existing bank is the path of least resistance.
4. Compare current rates. Pull up the live CD table, check the Treasury daily yield curve on treasury.gov, and compare. If a promo CD beats the T-bill yield by more than your state-tax savings, take the CD.
5. Size your allocation. Balances above $250K should lean toward Treasuries to avoid juggling FDIC limits across multiple banks. Below $250K, CDs and Treasuries compete on yield and convenience.

Decision Framework: Choose X If … / Choose Y If …

Choose CDs if …

• You already bank at Marcus, Ally, or another top CD provider
• You live in a no-state-tax state (TX, FL, WA, TN)
• You want FDIC insurance and do not have brokerage access
• You are parking $5K–$50K and want one-click simplicity
• You can capture a promotional CD rate above the T-bill yield

Choose Treasuries if …

• You live in a high-tax state (CA, NY, NJ, IL, MA)
• Your balance exceeds $250K (no FDIC cap to manage)
• You have a brokerage account at Fidelity, Vanguard, or Schwab
• You might need to sell before maturity (better liquidity than CDs)
• You want the absolute lowest-risk yield available

Choose corporate bonds if …

• You are income-focused (retirees, conservative allocation)
• You can diversify across multiple issuers ($100K+ or use bond ETFs)
• You are comfortable with interest-rate volatility
• You want a yield premium of roughly 0.7–1.5 points over Treasuries
• You have research time or prefer bond funds like BND, AGG, or SPSB

Real-World Scenarios

Scenario 1: Young professional, $25K emergency fund, Texas

Jake is 29, lives in Houston, and has $25K he wants to keep accessible but productive. He has no state income tax, so the Treasury's tax exemption gives him nothing extra — for him, it's a pure yield comparison, and a top CD at … currently beats a 12-month T-bill at 4.40% outright. Because Jake already has a Marcus savings account, opening a Marcus 12-month CD is the simplest move even though it isn't the single highest rate available: he earns roughly … before federal tax. If he needed true daily access, a high-yield savings account at … would be the better call: slightly lower yield, but no penalty for early withdrawal.

Scenario 2: Retiree, $300K, New Jersey

Linda is 67 and has $300K earmarked for living expenses over the next two years. She lives in New Jersey (10.75% state rate). Splitting between CDs would require two banks to stay under the $250K FDIC limit. Instead, she buys a mix of 6-month and 12-month T-bills through her Fidelity account. Her state-tax exemption on $300K at today's Treasury yield is worth roughly $1,322 per year, enough to cover a month of groceries — though she should still weigh that against the CD's currently higher nominal rate before deciding. For an additional income sleeve, she allocates $50K to a short-term corporate bond ETF (SPSB) yielding about 5.3%. She accepts the modest credit risk because the money is not needed for 18+ months.

Scenario 3: Couple, $100K, California, laddered approach

David and Sarah live in San Jose and have $100K they will need in stages over the next 18 months. They build a simple ladder:

• $25K → 3-month T-bill at roughly 4.30%
• $25K → 6-month T-bill at roughly 4.40% (as of June 2026 — no live 6-month Treasury token exists on this site; verify the current yield before committing)
• $25K → 12-month T-bill at 4.40%
• $25K → 18-month CD at roughly …

Every three months, $25K becomes available. The four rungs won't all yield the same amount, so use the CD calculator with today's actual rates for a real blended-yield estimate rather than relying on a single averaged number that goes stale as any one rung's rate moves. The T-bill portions are state-tax exempt, which meaningfully narrows or reverses the gap for a couple in a high-tax state like California. As each rung matures, they reinvest into a new 18-month rung to keep the ladder rolling.

What About HYSAs as a Fourth Option?

For pure liquid cash, your emergency fund, a high-yield savings account earning 4.20% (today's top rate) is usually better than locking into a 12-month CD or Treasury. The HYSA vs CD comparison covers that trade-off in depth. Quick decision tree:

The most common mistake: parking cash in a CD when a HYSA would deliver a similar yield with full liquidity. If you might need the money before the CD matures, the early-withdrawal penalty often wipes out the yield advantage entirely. Our best high-yield savings guide ranks current options.

Methodology

SwitchWize verifies CD, Treasury, and savings rates at least weekly using primary sources: bank websites, TreasuryDirect.gov yield data, and SEC filings for bond funds. After-tax comparisons use federal and state marginal rates published by the IRS and state revenue departments. We rank products by after-fee, after-tax yield for a typical saver, not by promotional headline rate alone. Full details are available on our methodology page.

Quick answer

A CD, a bond, and a Treasury bill can all provide predictable income, but they are not interchangeable. A bank CD is an FDIC-insured deposit held to maturity. A bond can lose market value when rates rise. A Treasury bill is a short government security with a different tax profile and no FDIC insurance. Match the instrument to the horizon, liquidity need, and tax bracket before comparing yields. The right choice is often different for emergency cash, a one-year bill, and a long-term portfolio. Compare after-tax income and the price of selling early, not just the stated coupon or APY.
