The Fed held rates at 3.5-3.75% on March 18 and revised the dot plot down to just one cut for all of 2026. Probably September. That means the window to lock in 4%+ CD rates is open right now, but it has an expiration date.

Unlike a high-yield savings account where the rate floats down the moment the Fed moves, a CD freezes today’s rate for 12, 18, even 24 months. That’s the whole pitch. You’re betting that today’s rate is better than what you’ll get later. And based on the FOMC’s own projections, that bet looks solid.

Top 1-year CDs are paying 4.20% APY right now. The national average for a 12-month CD? 1.89%. That’s a $231 difference on every $10,000 — same money, same FDIC insurance, zero additional risk. You just have to pick the right bank.

Best CD Rates — March 2026

Term	Bank	APY	Minimum	Early Withdrawal Penalty
6-month	Bread Financial	4.15%	$1,500	90 days of interest
9-month	Marcus by Goldman	4.10%	$500	270 days of interest
12-month	Bread Financial	4.20%	$1,500	150 days of interest
12-month	Popular Direct	4.20%	$10,000	270 days of interest
18-month	Synchrony Bank	4.00%	$0	180 days of interest
24-month	Ally Bank	3.80%	$0	150 days of interest
5-year	Ally Bank	3.60%	$0	150 days of interest

Quick take: The 12-month sweet spot is 4.20% at Bread Financial or Popular Direct. Go shorter if you think rates might rise (unlikely given the dot plot). Go longer if you want to lock in 3.80%+ for two years and forget about it.

What a CD Actually Gets You

A certificate of deposit is the simplest fixed-income product that exists. You hand the bank money. They pay you a guaranteed rate for a set period. If you pull your money out early, you pay a penalty, usually a few months of interest.

That’s it. No market risk, no rate fluctuation. You’re not checking an app at midnight wondering if your yield dropped. FDIC insured up to $250,000 per depositor, per institution.

The math on $10,000 across different terms:

Term	Top Rate	Earnings	National Average (1.89%)	Difference
6-month	4.15%	$207	$94	+$113
12-month	4.20%	$420	$189	+$231
18-month	4.00%	$604	$284	+$320
24-month	3.80%	$774	$381	+$393

That $231 gap on a 12-month CD isn’t life-changing money. But it’s money that required exactly one decision and zero ongoing effort. I’ll take it.

Why CDs Make More Sense Right Now Than They Did Last Year

The March 18 FOMC statement changed the math. The dot plot now projects just one rate cut in 2026 — down from the two cuts projected in December 2025. The likely timing is September, based on the median dot.

Here’s what that means for you:

HYSA rates will drift lower. My Wealthfront cash account was paying 5.00% in 2024. It’s at 4.20% now. After a September cut, expect 3.75-4.00%. Variable rates follow the Fed down, every time.

CD rates lock in. A 12-month CD opened today at 4.20% stays at 4.20% even if the Fed cuts twice. You’re insulated. That locked rate becomes more valuable the more the Fed cuts.

The spread is narrowing. Right now, the best HYSAs and the best 12-month CDs are paying roughly the same — around 4.20%. That means you’re not giving up yield to lock in. Six months from now, if the HYSA drops to 3.75% and your CD is still paying 4.20%, you’ll be glad you moved.

I opened a 12-month CD at Bread Financial two weeks ago. Not my entire savings — I keep my emergency fund liquid in a HYSA. But the chunk I know I won’t touch for a year? Locked at 4.20%.

How to Build a CD Ladder (And Why It Solves the Liquidity Problem)

The biggest knock on CDs is that your money is locked up. Fair. But a CD ladder fixes this without giving up much yield.

What’s a CD Ladder?

A CD ladder splits your money across multiple CDs with staggered maturity dates. Instead of putting $20,000 into one 12-month CD, you spread it across four terms. Every few months, a CD matures and you get to either use the money or reinvest it.

Example: $20,000 Four-Rung Ladder

Rung	Amount	Term	APY	Matures
1	$5,000	3-month	3.90%	June 2026
2	$5,000	6-month	4.15%	September 2026
3	$5,000	12-month	4.20%	March 2027
4	$5,000	18-month	4.00%	September 2027

Blended APY: ~4.06%

When Rung 1 matures in June, you have options. Need the cash? Take it. Don’t need it? Roll it into a new 18-month CD at whatever rate is available, and now your ladder extends further.

Every quarter, something matures. You always have money coming available. But you’re still earning 4%+ on most of it, locked in before the Fed cuts.

I set up a version of this last month. Three rungs — 6, 12, and 18 months — with about $15,000 total. The 6-month rung is my “what if I need it” safety valve. The 12 and 18-month rungs are the real income generators.

The Quarterly Reinvestment Cycle

After your first rung matures, you reinvest at the longest term in your ladder. The pattern:

1. June 2026: 3-month CD matures. Reinvest in an 18-month CD (matures December 2027)
2. September 2026: 6-month CD matures. Reinvest in an 18-month CD (matures March 2028)
3. March 2027: 12-month CD matures. Reinvest in an 18-month CD (matures September 2028)
4. September 2027: Original 18-month CD matures. Reinvest again

Within 18 months, every rung is an 18-month CD maturing at different intervals. You’ve built a rolling income stream that captures whatever rates exist at each reinvestment point while keeping liquidity every few months.

CDs vs. HYSAs: When to Use Which

I wrote about the best HYSA rates last week. CDs and HYSAs aren’t competing products — they’re complements. Here’s how I think about the split:

Use a HYSA for:

• Emergency fund (you need instant access)
• Money you’ll spend within 3-6 months
• Savings where you’re still deciding what to do with it

Use a CD for:

• Money you won’t touch for 6-24 months
• Savings goals with a known timeline (down payment, tuition, car)
• Locking in rates before the Fed cuts

Use both for: Building a system where your liquid cash earns 4.20% in a HYSA while your longer-term savings earn 4.00-4.20% locked in a CD, protected from rate drops.

The worst move is leaving everything in a big bank savings account at 0.39%. Whether you pick a HYSA, a CD, or both — the gap between doing something and doing nothing is hundreds of dollars per year.

CDs vs. I Bonds: The Other Fixed-Income Option

I Bonds are paying a 4.03% composite rate through April 2026. That makes them look competitive with CDs. But the details are different enough to matter.

Factor	12-Month CD	I Bonds
Rate	4.20% (fixed for term)	4.03% (resets every 6 months)
Rate risk	None until maturity	Rate changes with inflation
Purchase limit	None (FDIC up to $250K)	$10,000/year per person
Liquidity	Penalty if early	Can’t touch for 12 months, 3-month interest penalty before 5 years
Tax treatment	State + federal	Federal only (no state tax)

If you’re in a high-tax state — California, New York, New Jersey — the I Bond’s state tax exemption can close that 0.17% rate gap. On $10,000 at a 5% state rate, that saves you roughly $20.

But the $10,000 annual purchase limit is the real constraint. You can’t build a meaningful CD ladder equivalent with I Bonds. They’re a good complement, not a replacement. I buy my $10,000 in I Bonds every January and use CDs for anything above that.

Who CDs Are Best For

You have $5,000-$100,000 in savings earning basically nothing. This is most people. Moving even half of it into a CD ladder at 4%+ is free money. Literal free money, FDIC insured, guaranteed.

You know you won’t need certain funds for 6+ months. Down payment you’ll use next spring. Tuition due in January. Tax bill you’re saving toward. CDs match savings to timelines perfectly.

You’re nervous about the market but hate earning 0.39%. If the idea of putting money into an index fund gives you anxiety, a CD is the zero-risk alternative that still beats inflation. Barely, but it beats it.

You want to lock in rates before the Fed cuts. This is the time-sensitive argument. If the September cut happens, today’s 4.20% becomes tomorrow’s 3.75%. A 12-month CD opened now holds that rate through March 2027 regardless.

Who Should Skip CDs

If you need the money accessible at all times. CDs have penalties. Even a mild one eats your yield. Stick with a HYSA for your emergency fund.

If you’re investing for growth over 5+ years. A CD paying 4.20% doesn’t compete with equities averaging 8-10% over a decade. CDs are for capital preservation, not wealth building. Your dividend portfolio or broad market index fund should be doing the heavy lifting.

If you’re chasing the absolute highest yield. Some brokered CDs through Fidelity or Schwab occasionally beat direct bank CDs, but they work differently (secondary market pricing, no early withdrawal — you sell at market value). If you’re optimizing for every basis point, you’re probably past needing this article.

Early Withdrawal Penalties: Not as Scary as They Sound

Most people avoid CDs because they’re afraid of getting penalized. The penalties are real but modest.

On a 12-month CD at Bread Financial, the early withdrawal penalty is 150 days of interest. On $10,000 at 4.20%, that’s about $172. If you withdraw at month 8, you’ve earned roughly $280 in interest and give back $172. You still come out ahead of a savings account paying 0.39%.

The penalty makes early withdrawal suboptimal, not catastrophic. I wouldn’t recommend planning to break a CD early. But knowing the math takes the fear out of it.

How to Open a CD (5-Minute Process)

1. Pick a bank and term from the table above
2. Open an account online — SSN, address, funding source
3. Choose your CD term and deposit amount
4. Confirm the rate and maturity date
5. Set a calendar reminder for maturity so you don’t let it auto-renew at a worse rate

That last point matters. Banks love auto-renewal because the renewal rate is almost always lower than the promotional rate. Set the reminder. When it matures, shop rates again.

What Happens After September

If the Fed cuts 25 basis points in September (the dot plot’s base case), top CD rates will likely settle around 3.75-4.00% by late 2026. Still good — still way above the national average. But below where they are today.

The longer the Fed holds, the longer this window stays open. And given the March FOMC statement’s hawkish tilt — inflation still above target, labor market resilient — there’s a real chance they hold through September too. One cut in 2026 might become zero cuts.

Either way, locking in 4.20% today looks reasonable. If rates stay flat, you earned market rate. If rates fall, you beat the market. The only scenario where you lose is if rates rise significantly — and the Fed has signaled the opposite.

The Bottom Line

CDs are boring. That’s the point. They pay a guaranteed rate, they’re FDIC insured, and right now they’re paying 4.20% APY on 12-month terms while the national average sits at 1.89%.

The Fed’s March 18 dot plot says one cut this year, likely September. After that cut, today’s rates are gone. A CD ladder — 3, 6, 12, and 18-month rungs — locks in current rates while keeping money accessible every few months.

If you’re already earning 4%+ in a HYSA, CDs are an optional upgrade for money you won’t need short-term. If you’re still at a big bank earning next to nothing, CDs (or a HYSA, or both) should be your first move. The profitability of any side project should be measured against this risk-free 4.20% baseline.

Fifteen minutes. One decision. $420 per year per $10,000. The math speaks for itself.
