A fractional CD is a small slice of a bank-issued certificate of deposit that you buy through a brokerage account instead of at a bank. The brokerage purchases a large CD from an issuing bank, divides it into pieces as small as $100, and sells those pieces to individual investors. Your money still earns a fixed rate for a set term and is still FDIC-insured up to $250,000, but the way you buy the CD, exit it early, and receive your money back at maturity works differently than at a bank branch.
How a Fractional CD Works
Banks issue large-denomination CDs to brokerage firms, which then carve those CDs into smaller pieces and offer them to customers. The SEC describes this arrangement as a “master CD” issued to the deposit broker, who then sells interests in that master CD to investors.1Investor.gov U.S. Securities and Exchange Commission. Brokered CDs: Investor Bulletin The brokerage’s role is to source competitive rates across a national network of banks, giving you access to yields you wouldn’t find by walking into a single branch.
Your fractional CD is held in “street name,” meaning the brokerage firm is the owner of record with the issuing bank while you remain the beneficial owner. The SEC explains that this is standard practice for securities held in brokerage accounts: the firm keeps internal records showing you as the real owner, even though the bank doesn’t send you a certificate directly.2U.S. Securities & Exchange Commission. Street Name Interest payments flow from the issuing bank through the brokerage and into your account automatically.
Payment frequency depends on the CD’s term. For CDs maturing in one year or less, interest is generally paid at maturity. Longer-term CDs may pay monthly, quarterly, or semiannually, depending on the issuing bank’s terms.3Vanguard. Brokered Certificates of Deposit (CDs)
How a Fractional CD Differs From a Bank CD
Three practical differences separate a fractional CD from the CD you’d open at a local branch: the minimum investment, how you exit early, and the rates on offer.
Lower Minimums
Most bank CDs require $500 to $1,000 to open. Fractional CDs lower that bar. Fidelity offers fractional CDs with a $100 minimum and $100 increments.4Fidelity. Certificates of Deposit (CDs) – Fixed Income Investment Schwab and Vanguard set their minimums at $1,000 with $1,000 increments.3Vanguard. Brokered Certificates of Deposit (CDs) Small increments make it practical to spread a modest sum across several banks and maturity dates.
A Different Way Out Before Maturity
Break a bank CD early and you forfeit some interest, often around three months on a one-year CD and roughly eight and a half months on a five-year. Fractional CDs skip that penalty structure entirely. Instead of withdrawing from the bank, you sell your CD to another investor on a secondary market.1Investor.gov U.S. Securities and Exchange Commission. Brokered CDs: Investor Bulletin The catch is that the price you get depends on where interest rates stand when you sell, and you can end up with less than you put in.
Often Better Rates
Because brokerage firms bring large sums to issuing banks, they can frequently negotiate higher yields than any single branch offers its walk-in customers.1Investor.gov U.S. Securities and Exchange Commission. Brokered CDs: Investor Bulletin Competing for that money is one of the main reasons investors use fractional CDs.
How to Buy and Sell a Fractional CD
You buy fractional CDs through a brokerage account, either on the firm’s fixed-income platform or through its trading desk. The process feels more like buying a bond than opening a bank account. You browse available CDs by issuing bank, maturity date, and yield, then place an order.
New-issue CDs are typically sold at par value, either $1,000 per standard CD or $100 per fractional CD depending on the brokerage. Major brokerages generally don’t charge investors a separate transaction fee on new issues. Fidelity, for example, states that new-issue CDs are available without a trading fee, though the firm receives compensation from the issuer for participating as a selling group member.4Fidelity. Certificates of Deposit (CDs) – Fixed Income Investment
Need your money before the CD matures? You sell it on the secondary market. This is a transaction with another investor, not a withdrawal from the bank. Expect a markup or markdown from the brokerage on secondary trades. Fidelity’s standard markup is $1 per CD.5Fidelity Investments. Learn More About Brokered CDs
Fractional CDs are also eligible for tax-advantaged accounts. You can hold them inside a traditional IRA, Roth IRA, or other retirement account at your brokerage.
FDIC Insurance
Fractional CDs are FDIC-insured just like bank CDs. The standard coverage limit is $250,000 per depositor, per insured bank, per ownership category.6FDIC. Deposit Insurance FAQs The insurance attaches at the issuing bank, not at the brokerage. Through “pass-through” insurance, the FDIC looks through the brokerage’s street-name registration to the underlying beneficial owner and insures your deposits at each issuing bank separately.7FDIC.gov. Your Insured Deposits
That creates both an opportunity and a bookkeeping task. Because each issuing bank’s deposits are insured separately, you can spread money across CDs from different banks and stay under the limit at each one. But you have to track totals yourself. If you already hold a checking account at the same bank that issued one of your brokered CDs, the FDIC adds those balances together for insurance purposes.7FDIC.gov. Your Insured Deposits
FDIC insurance covers the failure of the issuing bank. A separate protection, from the Securities Investor Protection Corporation (SIPC), applies if the brokerage itself is liquidated. SIPC protects customer assets, including CDs held as securities, up to $500,000 with a $250,000 sub-limit for cash.8SIPC. What SIPC Protects SIPC does not protect against declines in market value and is not a substitute for FDIC insurance.
What Are the Risks
Fractional CDs are among the safest investments available. Safe is not the same as risk-free, and three risks are worth knowing before you buy.
Interest Rate Risk on Secondary Market Sales
Hold to maturity and you get your full principal back, assuming the bank hasn’t failed. Sell early after interest rates have risen and your CD’s fixed rate looks less attractive to buyers, so the sale price drops below what you paid. The SEC warns that you “may lose some of your original investment due to a change in the market price of the CD.”1Investor.gov U.S. Securities and Exchange Commission. Brokered CDs: Investor Bulletin The reverse can also happen: if rates have fallen, you may sell for more than you paid.
Liquidity Risk
The secondary market gives you a way out, but not a guaranteed one. E*TRADE notes that “there is no guarantee that you will be able to sell your brokered CDs prior to maturity,” because whether you can sell depends on demand.9E*TRADE. Understanding Brokered CDs If few buyers want your specific CD, finding a reasonable price can be hard. That’s most likely with CDs from smaller, less-recognized issuing banks or during periods of market stress.
Call Risk
Some brokered CDs are callable, meaning the issuing bank can redeem the CD before maturity. Banks typically exercise this right after interest rates have dropped, because they’d rather stop paying you the old, higher rate. You get your principal back but have to reinvest at whatever lower rates are available. Callable CDs usually pay a slightly higher rate upfront to compensate.9E*TRADE. Understanding Brokered CDs Check whether a CD has a call provision before buying. The call date and terms are in the offering details.
What Happens at Maturity
This is where brokered CDs catch people off guard. A bank CD typically auto-renews into a new term if you don’t act during a brief grace period. Fractional CDs do not auto-renew. When yours matures, the issuing bank pays the principal and final interest to your brokerage, where the money lands in your cash or money market sweep account. Staying in CDs means actively buying a new one. Leaving the proceeds in a low-yield sweep account is one of the most common mistakes brokered CD investors make, because the maturity date can slip by with only a routine account statement to mark it.
The Survivor’s Option
Many brokered CDs include a feature called a “survivor’s option” or “death put.” If the CD holder dies, the estate’s representative can request redemption at full face value regardless of current market rates or whether the CD has reached maturity.10Raymond James. Estate Planning with Bonds – Fixed Income Strategies That avoids the secondary market and eliminates interest rate risk for heirs. Not every brokered CD includes this provision, so check the offering documents if estate planning matters to you.
Tax Treatment
Interest earned on a fractional CD is taxable as ordinary income in the year it’s received or accrued, the same as interest on a bank CD. Your brokerage reports interest payments on Form 1099-INT. If you bought the CD at a discount on the secondary market, the difference between your purchase price and par may be treated as original issue discount, reported on Form 1099-OID.11Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID
Selling a fractional CD on the secondary market before maturity creates a capital gain or loss. You report the transaction on Form 8949 by subtracting your cost basis from the sale proceeds.12Internal Revenue Service. Instructions for Form 8949 Held for one year or less, the gain is short-term and taxed at ordinary income rates. Held for more than a year, the gain qualifies for the lower long-term capital gains rate. Losses can offset other capital gains.
Holding fractional CDs inside an IRA or other tax-advantaged retirement account removes these annual filings from the picture, since interest accumulates tax-deferred, or tax-free in a Roth IRA, until distribution.
