Bottom line: Three fixed-yield options for cash that differ in rate, taxation, and what happens if you sell early. Brokered CDs pay the highest headline rates but expose you to price risk if you sell before maturity. Bank CDs lock in a rate with predictable early-withdrawal penalties. Treasury bills pay slightly less than CDs on a headline basis but win after tax for high-tax-state residents. The right choice depends on your tax bracket and whether you'll hold to maturity.
The most common cash-yield comparison in personal finance is HYSA versus CD. The more sophisticated comparison is among the three fixed-rate options: a CD purchased directly from a bank, a CD purchased through a brokerage account ("brokered CD"), and a U.S. Treasury bill or note.
All three lock in a fixed yield for a defined period. All three are extremely safe — bank CDs and brokered CDs are FDIC-insured; Treasuries are backed by the full faith and credit of the U.S. government. The differences are in the mechanics: how you buy them, what the rate actually is, how they're taxed, and what happens if you need access before maturity.
For balances above $25,000, the choice between these three can mean hundreds of dollars per year in additional yield — or, in the wrong situation, hundreds of dollars in unnecessary losses if you have to sell early. This guide covers the math.
The Three Products
Bank CD (Direct from Bank)
What it is: A deposit at an FDIC-insured bank. You give the bank money for a fixed term; the bank pays you a fixed rate; at maturity you receive principal plus interest.
Rate today (12-month): Top rates approximately 4.15% APY. Top providers in 2026 include Marcus, Synchrony, Ally, and Capital One.
FDIC insurance: Yes, up to $250,000 per depositor per bank.
Early access: If you need money before maturity, you pay an early withdrawal penalty (typically 3 months of interest on short-term CDs, 6–9 months on long-term CDs). You always get principal plus accrued interest minus the penalty. You cannot lose principal.
Taxation: Interest is taxable as ordinary income at both federal and state levels. Reported on IRS Form 1099-INT.
Where it wins: Predictable, fully-insured, no surprises. You always know exactly what you'll get back if you hold to maturity or if you withdraw early.
Brokered CD (Through Your Brokerage Account)
What it is: A CD issued by a bank but sold through a brokerage firm (Fidelity, Schwab, Vanguard, Merrill Edge, E*TRADE). The bank issues the CD; the brokerage sells it to you; the CD lives in your brokerage account.
Rate today (12-month): Top brokered rates approximately 4.15% — typically 10–30 basis points above direct bank CDs.
FDIC insurance: Yes, up to $250,000 per issuing bank. Important nuance: each brokered CD is from a specific bank, so if you buy multiple brokered CDs through one brokerage, each bank's $250,000 limit applies separately. You can hold $1M+ in brokered CDs at one brokerage and have all of it insured, as long as the underlying banks are different.
Early access: No early withdrawal penalty. Instead, you sell the CD on the secondary market through your brokerage. The price you receive depends on current interest rates — if rates have risen since you bought, the resale price is below face value (you lose money); if rates have fallen, the resale price is above face value (you gain).
Taxation: Same as bank CDs — interest taxable as ordinary income at both federal and state levels. Reported on 1099-INT from your brokerage.
Where it wins: Higher yield than bank CDs, plus the option to sell for liquidity (with price risk). Best for sophisticated buyers who understand interest-rate sensitivity and either plan to hold to maturity or are comfortable with the price risk.
U.S. Treasury Bill or Note
What it is: Short-term debt issued by the U.S. federal government. Treasury bills (T-bills) have maturities of 4 weeks to 52 weeks. Treasury notes have maturities of 2–10 years. You can buy directly through TreasuryDirect.gov or through any brokerage account.
Rate today (1-year): Approximately 4.10%.
Safety: Backed by the full faith and credit of the U.S. government. There is no $250,000 cap on this guarantee — the entire balance is government-backed regardless of size.
Early access: Sold on the secondary market through your brokerage (or held to maturity at TreasuryDirect). Same price-risk dynamic as brokered CDs — if rates have risen, you sell at a loss; if rates have fallen, you sell at a gain.
Taxation: Federal income tax applies. Exempt from state and local tax. This is the meaningful structural advantage versus both CD types.
Where it wins: High-tax-state residents holding above $250,000 in cash. The state tax exemption combined with the unlimited federal guarantee makes Treasuries the right answer for these readers.
The Rate Comparison
The headline rates differ, but the meaningful comparison is after tax. The table below works out the math on a $50,000 balance held for 12 months across three representative state tax environments.
Scenario: $50,000 for 12 months
| Product | Headline rate | Pre-tax interest | Federal tax (24% bracket) | State tax | After-tax interest |
|---|---|---|---|---|---|
| Texas resident (0% state) | |||||
| Bank CD (Marcus 12mo) | 4.40% | $2,200 | $528 | $0 | $1,672 |
| Brokered CD (12mo) | 4.60% | $2,300 | $552 | $0 | $1,748 |
| 1-year Treasury | 4.10% | $2,050 | $492 | $0 | $1,558 |
| California resident (9.3% state) | |||||
| Bank CD (Marcus 12mo) | 4.40% | $2,200 | $528 | $205 | $1,467 |
| Brokered CD (12mo) | 4.60% | $2,300 | $552 | $214 | $1,534 |
| 1-year Treasury | 4.10% | $2,050 | $492 | $0 | $1,558 |
| New York resident (10.9% state, top bracket) | |||||
| Bank CD (Marcus 12mo) | 4.40% | $2,200 | $528 | $240 | $1,432 |
| Brokered CD (12mo) | 4.60% | $2,300 | $552 | $251 | $1,497 |
| 1-year Treasury | 4.10% | $2,050 | $492 | $0 | $1,558 |
Three patterns emerge.
In no-income-tax states, brokered CDs win unambiguously. The 20-basis-point rate advantage over bank CDs and the 50-basis-point advantage over Treasuries dominate when there's no state tax exemption to capture.
In California, the Treasury wins by a hair. The state tax exemption is worth 9.3% of the brokered CD's interest — about $214 on $50,000. That savings offsets the Treasury's lower headline yield. The brokered CD is a close second.
In New York (and similar high-tax states), the Treasury wins more clearly. As state tax rates rise, the Treasury exemption becomes more valuable. Above roughly 8% state tax, Treasuries typically beat both CD types after tax.
The crossover point is approximately a 5% state tax rate. Below that, CDs (especially brokered) win. Above it, Treasuries win.
The Liquidity Trade-Off
The rate comparison is only half the picture. The other half is what happens if you need access to the money before maturity.
Bank CD: Predictable Penalty
If you withdraw a $50,000 12-month bank CD after 6 months, the bank applies its early withdrawal penalty. For a Marcus 12-month CD at 4.40% APY, the penalty is 90 days of interest — approximately $540 on the $50,000 balance. You receive principal ($50,000) plus accrued interest to date ($1,080 for 6 months) minus the penalty ($540) = $50,540.
This is predictable. You always get principal back. The math is the same regardless of where interest rates have moved since you bought.
Brokered CD: Market-Price Risk
If you sell a $50,000 12-month brokered CD on the secondary market after 6 months, the price depends on current interest rates.
If interest rates on new 6-month CDs have risen 50 basis points since you bought, buyers in the secondary market will only pay for your CD at a discount that reflects the rate difference. A rough rule: each 1% change in interest rates over the remaining term moves the price by about 1% of face value, scaled by remaining duration. On a 12-month CD with 6 months remaining, a 50 bp rate increase typically reduces the price by about 0.25% — so you'd receive approximately $49,875 instead of $50,000. Add 6 months of accrued interest, and your total return is roughly $50,975 — slightly better than the bank CD scenario.
If interest rates have fallen 50 basis points, the opposite occurs. The CD's fixed rate is now above-market, so buyers pay a premium. You might sell for $50,125, plus 6 months of accrued interest, for a total of $51,225.
The asymmetry: in a rising-rate environment, brokered CDs sold early can underperform bank CDs (where the penalty is known and fixed). In a falling-rate environment, brokered CDs sold early outperform bank CDs.
Over the past 24 months, this has mattered. Investors who bought 5-year brokered CDs in late 2023 at peak rates have seen their CDs trade at a premium as rates have softened — they could sell early and profit. Investors who bought 5-year brokered CDs in early 2022 before rates rose sharply faced significant losses if they needed to sell.
Treasury Bill or Note: Same Market-Price Risk as Brokered CDs
The same dynamic applies. Treasuries sold on the secondary market trade at prices that reflect current interest rates. If rates have risen since you bought, you sell at a loss. If they've fallen, you sell at a gain.
The one difference: Treasury market liquidity is dramatically deeper than brokered CD market liquidity. T-bills and Treasury notes are among the most liquid securities in the world. Bid-ask spreads are minimal. You can sell $50,000 in Treasuries at any business hour with confidence in the execution.
Brokered CDs have thinner secondary markets. Smaller-issuer brokered CDs can have wider spreads or longer execution times. For balances above $250,000, this can mean a 5–10 basis point cost to liquidate beyond just the interest-rate-driven price change.
The FDIC Coverage Mechanics
A subtle but important difference among the three products.
Bank CD: $250,000 per depositor per bank. If you hold $300,000 across two bank CDs at the same bank, $50,000 is uninsured.
Brokered CD: $250,000 per depositor per issuing bank. Each brokered CD has a specific bank as its issuer. If you buy $250,000 of brokered CDs from Bank A and another $250,000 from Bank B through the same brokerage account, all $500,000 is insured — because the limit applies per issuing bank, not per brokerage.
This is the structural advantage of brokered CDs for large balances. You can hold $1M+ in fully-insured CDs through one Fidelity or Schwab account, as long as the underlying issuing banks are different. This is dramatically simpler than managing multiple bank logins.
Treasury bills/notes: No coverage limit. The U.S. government's full faith and credit applies to the entire balance. For $1M+ in cash, Treasuries effectively eliminate the FDIC-limit complexity entirely.
When Each One Wins
Pick a Bank CD when...
- You want maximum predictability — known penalty if you withdraw early, principal always returned
- Your balance is under $250,000 at a single bank
- You don't have a brokerage account and don't want to open one
- You hold a strong banking relationship with the issuing bank and value the consolidated experience
Pick a Brokered CD when...
- You want the highest yield on a fixed-term CD
- You already have a brokerage account where you actively manage money
- Your CD balance exceeds $250,000 — brokered CDs from multiple issuing banks let you maintain FDIC coverage on the full balance through one account
- You're confident you'll hold to maturity, OR you understand and accept the secondary-market price risk
Pick a Treasury when...
- You live in a state with meaningful income tax (5%+)
- Your cash balance exceeds the FDIC limit and you want to skip the multi-bank setup
- You want the deepest secondary-market liquidity if you might sell early
- You want the highest-grade credit backing (U.S. government direct)
The Common Setup for Sophisticated Savers
For readers with $100,000+ in cash, the most common professional setup is a combination of all three:
- HYSA at top rate: 1–3 months of expenses for liquidity
- Short-term Treasury bills (3- and 6-month): Tax-efficient yield on cash that might be needed in the next 6–12 months
- Brokered CD ladder (1- to 5-year terms): Bulk of long-term cash, held to maturity, with the highest fixed yield available
- Direct bank CD (optional): One position at a primary bank for the relationship, even at slightly lower yield
This approach captures the rate advantages of brokered CDs on most of the balance, the tax efficiency of Treasuries on tax-sensitive money, and the operational simplicity of a HYSA on the actively-managed liquid portion. The exact allocation depends on personal cash flow patterns and tax situation.
The Mistakes That Recur
Buying brokered CDs without understanding secondary-market price risk. The most common mistake. Investors comparing the headline rate of a brokered CD to a bank CD see only the upside. The early-exit math is different and asymmetric. If there's any chance you'll need the money before maturity, the predictability of a bank CD's penalty can be worth more than the brokered CD's rate premium.
Ignoring state tax in the comparison. A California resident comparing a 4.60% brokered CD to a 4.10% Treasury sees the rate gap. They often miss that the Treasury's after-tax yield is higher.
Treating all brokered CDs as equivalent. Brokered CDs are issued by hundreds of banks of varying size and balance-sheet strength. While the FDIC insurance covers principal regardless of issuer, the secondary-market liquidity is dramatically different between large-issuer CDs (where there's a deep buyer pool) and small-issuer CDs (where you may have to wait or accept wider spreads). For brokered CDs you might need to sell early, prefer larger, more recognized issuers.
Holding brokered CDs in taxable accounts when Treasuries would be more efficient. For high-tax-state residents, the same dollar parked in a Treasury versus a brokered CD can be 30–50 basis points more efficient after tax. This adds up substantially on $100,000+ balances.
The Decision in One Table
| Your situation | Best choice |
|---|---|
| <$25,000, no brokerage, want simplicity | Bank CD |
| $25,000–$250,000, no brokerage | Bank CD or open a brokerage and use brokered CD |
| $25,000–$250,000, have brokerage, low-tax state | Brokered CD |
| $25,000–$250,000, have brokerage, high-tax state | Treasury (or brokered CD by small margin) |
| $250,000–$1M, want one account | Brokered CDs from multiple issuing banks |
| Any balance, high-tax state (8%+) | Treasury ladder |
| Any balance, might need early access | Bank CD (predictable penalty) or Treasury (liquid secondary market) |
| Maximum yield, willing to hold to maturity | Brokered CD |
The flat yield curve in mid-2026 — where 1-year and 5-year CD rates are within 40 basis points of each other — limits the absolute scale of the choice. But on $100,000+ balances over multi-year horizons, picking the right product among these three can mean $1,000–$3,000 in additional after-tax yield versus picking the wrong one. The difference is large enough to warrant getting it right.
