If you’ve been shopping for a place to park cash you don’t need immediately, you’ve probably noticed two flavors of certificates of deposit showing up in your search results. There’s the familiar bank CD, sold by your local credit union or by the online bank where you keep your savings, and then there’s the brokered CD, which lives inside a brokerage account at firms like Fidelity, Schwab, or Vanguard. They look like cousins on a rate comparison page, and both come with FDIC insurance up to the standard limits, so the temptation is to grab whichever offers the higher number and move on. That can work out fine, but the two products have important mechanical differences, and understanding them before you commit is the difference between locking in a smart fixed-income position and getting an unpleasant surprise a year from now.
The simplest way to think about the distinction is this: a bank CD is a deposit account you open directly with the issuing bank, while a brokered CD is a deposit account that a brokerage firm purchases on your behalf from a bank somewhere in its network. The brokerage acts as a middleman. They aggregate offerings from dozens of banks, present them in a single interface, and let you buy and sell those CDs the way you’d buy and sell a bond. That structural difference is what creates almost every other difference between the two products, and it’s worth walking through carefully.
Who issues them, and why that matters
Bank CDs come from a single bank that knows you, holds your deposit, and credits the interest. You usually have to open the account at the bank itself, and the term, rate, and minimum deposit are whatever that specific institution is offering that week. Brokered CDs are pulled from a much wider pool. According to Charles Schwab’s fixed-income team, a single brokerage can have dozens or even hundreds of CDs available on any given day, sourced from FDIC-insured banks across the country. That breadth is the biggest practical advantage of going through a brokerage. Instead of comparison shopping across ten bank websites, you see a list and sort by rate and term.
Because brokerages buy in bulk and can play banks against each other, brokered CDs sometimes carry slightly higher rates than the same bank’s branded CDs would. As Bankrate’s overview points out, this isn’t always the case, but it shows up often enough that comparing both is usually worth a few minutes.
How interest actually works
This is the difference that catches the most people off guard. Bank CDs typically compound interest. Your money earns interest, that interest gets added to your balance, and the next period’s interest is calculated on the new larger figure. That’s why a CD’s advertised APY can be slightly higher than its stated interest rate.
Brokered CDs, on the other hand, almost always pay simple interest. The brokerage credits interest payments to your account on a schedule, usually monthly or semi-annually, and you decide what to do with the money. You can leave it sitting in cash, reinvest it elsewhere, or use it for income. If you want compounding, you have to manually reinvest, and the new investment will be at whatever rate is available at that moment. This makes brokered CDs feel more like bonds, which is exactly what they’re modeled on. For a short-term CD, the difference is small. For a five-year CD, the gap between compounded and simple interest can be a few percentage points of total return, so it’s worth doing the math both ways before you decide.
Liquidity and the secondary market
Bank CDs are generally meant to be held to maturity. If you pull your money out early, the bank charges an early withdrawal penalty, typically three to twelve months of interest depending on the term. The penalty is annoying, but it’s predictable. You know exactly what it’ll cost to break the CD.
Brokered CDs work differently. There’s no early withdrawal feature at all, but you can sell the CD on the secondary market through your brokerage. That sounds like an advantage, and sometimes it is, but the secondary market introduces interest rate risk that bank CDs don’t have. If interest rates have risen since you bought the CD, the market value of your CD drops, because new buyers can get higher rates elsewhere. Schwab’s brokerage notes that selling early can mean receiving less than your principal investment, and the loss can exceed what a bank CD’s early withdrawal penalty would have been. If rates have fallen, the opposite can happen and you might actually sell for a small premium. Charles Schwab charges $1 per $1,000 in face value on secondary CD trades with a $250 cap, and other brokerages have similar structures, so liquidity isn’t free either.
The callable feature you need to watch for
Some brokered CDs are callable, which means the issuing bank can redeem the CD before maturity, usually after a specific lockout period has passed. If interest rates fall, the bank may exercise the call and give you back your principal plus accrued interest, then issue new CDs at the lower prevailing rate. You’re stuck reinvesting at a worse number. The Bankrate guide on brokered CDs flags this as one of the most common misunderstandings new investors run into. Callable CDs usually offer a slightly higher rate to compensate for the call risk, so the higher headline yield isn’t always a free lunch.
Bank CDs almost always have a fixed term with no call option. What you sign up for is what you get. Before buying any brokered CD, look at the security details and confirm whether it’s callable, and if so, when the first call date is. If you need a guaranteed rate for the full term, stick with non-callable CDs, even if the rate is a touch lower.
FDIC insurance works for both, with one wrinkle
The good news is that FDIC insurance applies to brokered CDs the same way it applies to bank CDs, up to $250,000 per depositor per insured bank. According to the FDIC’s deposit insurance pages, the coverage flows through the brokerage to the underlying issuing bank. The wrinkle is that you need to track which banks your brokered CDs are issued from. If you already have a deposit at, say, Capital One, and your brokerage buys you a Capital One brokered CD, those deposits are aggregated for insurance purposes. Sophisticated buyers actually use brokered CDs to spread money across multiple banks and stay under the $250,000 limit at each one, which is much easier than opening accounts at ten different banks individually.
Which one is right for you
For straightforward savers who want a guaranteed rate with no surprises, bank CDs from a competitive online bank or credit union are usually the cleaner choice. You get predictable compounding, a defined early withdrawal penalty if life happens, and a simple relationship with one institution. NerdWallet’s current best CD rate roundup shows top bank CDs in the 4.0% to 5.0% APY range for terms between three months and a year, which is competitive with what’s available on the brokered side.
Brokered CDs make more sense when you want to build a multi-bank ladder, when you want to keep your fixed-income investments inside an existing brokerage for record-keeping, or when you want the optionality of selling early through the secondary market. They’re also useful if you’re managing larger balances and want to spread FDIC coverage across many issuers without opening a dozen accounts. The trade-off is that you have to read the security details carefully, understand whether the CD is callable, and accept that early liquidity isn’t free.
Whichever route you choose, the fundamentals of fixed income still apply. Match the term to when you actually need the money. Compare APY against your alternatives, including a regular high-yield savings account. And keep CDs as one slice of a broader plan rather than the whole strategy. The right CD does a specific job — protecting principal while earning a guaranteed return — and the better you understand which kind you’re buying, the better that job gets done.
