The simple version
A certificate of deposit (CD) pays a fixed rate for a fixed term. Open one at a bank and it is an agreement between you and that bank.
Buy one through a brokerage and you own a piece of a CD a bank issued in bulk. It pays the same way, but getting out early works completely differently.
The numbers
- Brokered CDs are generally issued by banks via a master CD to a deposit broker, who in turn offers to sell interests in that master CD to individual customers (U.S. Securities and Exchange Commission, investor bulletin on brokered CDs)
- Selling one in the secondary market can mean losing some of the original investment because of a change in the market price of the CD (U.S. Securities and Exchange Commission, same bulletin)
- If rates have risen since purchase there may be less demand for the lower-yielding CD, and if rates have fallen it may sell for a profit because it carries a higher rate (U.S. Securities and Exchange Commission, same bulletin)
- Brokered CDs may have call features, which give the issuing bank the right after a set period to redeem the CD before maturity, a right the holder does not have (U.S. Securities and Exchange Commission, same bulletin)
- Customers are insured up to $250,000 per customer, per insured bank, for each account ownership category (U.S. Securities and Exchange Commission, same bulletin)
Two ways to leave early
Pull money out of a bank CD early and the bank charges a penalty, usually measured in months of interest. The penalty is written in the account agreement before you ever sign.
A brokered CD usually cannot be cashed in with the bank. To get out early you sell it to another investor through the brokerage, at whatever price that investor will pay.
So one exit has a fixed, known cost. The other has a market price that depends on what interest rates did after you bought.
Why rates decide the price
Say you hold a CD paying 4% and new CDs of the same length now pay 5%. Nobody will pay full price for yours when a better one is available at full price.
So your CD sells at a discount, enough that the buyer's return matches what new CDs pay. The discount comes out of your original deposit.
It works in reverse too. The bulletin says plainly that if rates have fallen since you bought, you may be able to sell at a profit, because your CD carries the higher rate.
The Real Cost lens on selling before maturity
Here is the arithmetic with figures we chose. It assumes interest paid once a year and ignores sales fees and accrued interest, which real sales include.
- A $10,000 CD paying 4.00%, with three years left, pays $400 a year.
- If rates on new three-year CDs rise to 5.00%, a buyer values the remaining payments at about $9,728, so selling returns about $272 less than you put in.
- If rates instead fall to 3.00%, the same CD is worth about $10,283, or about $283 more than you put in.
- The instrument did not change in either case. Only the rate on everything else did.
Those figures are ours and describe no real CD. Holding to maturity avoids the price question entirely, because the bulletin describes the bank returning principal and interest on the maturity date. The price only matters if you sell early.
What this means
Brokered and bank CDs differ mainly in the exit. If there is any chance of needing the money before maturity, that difference is the whole comparison.
The call feature is worth reading too. If a call happens, the bulletin says the holder receives principal and the interest earned up to the call date, so what is lost is the remaining above-market yield rather than the deposit.
What this is NOT
This article does not recommend buying a brokered CD, a bank CD, or either instead of any other savings or investment, and it names no bank or brokerage. It does not forecast interest rates. The CD amounts, rates, and prices in the Real Cost section are illustrations we chose, and they ignore sales fees, accrued interest, and the gap between buying and selling prices, all of which affect real sales: the bulletin notes that a deposit broker may charge a fee to sell a brokered CD in the secondary market. Early withdrawal penalties on bank CDs are set by each bank's agreement and vary. Federal deposit insurance has limits and conditions, quoted here from the Securities and Exchange Commission as written rather than summarized, and nothing here should be read as saying every brokered CD is insured in every circumstance. The observation about what a call costs a holder is our reading of the bulletin's description, not a quoted conclusion. This article does not address how CD interest is taxed.
