What are Jumbo CDs? High-Balance Strategies for $100K+

Like any savings product, jumbo CDs come with clear advantages and a few trade-offs worth considering. 

Is a jumbo CD right for you?

If you have $100,000 or more sitting in a low-yield account and you don't need access to it for a set period, a jumbo CD can offer predictable returns. But if you might need access to those funds, other options may offer greater flexibility.

Historically, jumbo CDs commanded a meaningful rate premium. The idea was straightforward: a larger deposit meant more value for the bank, so they'd reward you with a better rate.

Recently, that premium has become much smaller and sometimes disappears entirely. Today, many high-yield standard CDs offer rates that match or even exceed those of jumbo CDs. The difference, when it exists, is often a matter of a few basis points.

A few things to consider when comparing rates:

• Look at APY, not just rate: Always compare annual percentage yield (APY), which accounts for compounding frequency. A slightly lower nominal rate compounded daily can outperform a higher rate compounded monthly.

• Assess term length: Longer-term CDs generally offer higher rates for both standard and jumbo CDs. Don't assume the jumbo version of a given term is always the better deal.

• Review multiple banking locations: Rates vary significantly between institutions. Online banks and credit unions often offer more competitive rates than traditional brick-and-mortar banks, regardless of deposit size.

One of the most important considerations for high-balance savers is deposit insurance. While bank CDs are FDIC insured up to a certain amount, the high balances could mean that some of your funds aren’t covered. 

The FDIC (Federal Deposit Insurance Corporation) insures deposits at member banks up to $250,000 per depositor, per institution. The NCUA (National Credit Union Administration) also provides a similar $250,000 in coverage for credit union deposits. That means if you deposit $250,000 or less at any one institution, your money is backed by the full faith and credit of the United States government in case of bank or credit union failure.

But if you're depositing $500,000 at a single bank in a jumbo CD, up to $250,000 of that balance may be uninsured.

For savers with larger balances, this is worth taking seriously. There are a few ways to manage the risk:

• Spread deposits across multiple institutions, each staying within the $250,000 limit.

• Open joint accounts, which can double the insured amount at a single institution to $500,000. Use a platform like Raisin, which makes it straightforward to distribute your savings across multiple FDIC-insured banks and NCUA-insured credit unions from a single login.

Not all jumbo CDs are built the same. Understanding the different structures helps you choose one that fits your goals and avoid surprises.

Here’s a quick breakdown:

Fixed-rate jumbo CDs 

Fixed-rate jumbo CDs are the most straightforward option. You lock in a rate for a set term, and it doesn't change. That predictability is useful if you're confident rates won't rise significantly during your term, but it can work against you if they do.

Callable jumbo CDs 

These CDs typically offer a higher initial rate in exchange for a trade-off: the issuing bank has the right to "call" (redeem) the CD before it matures. That usually happens when interest rates fall, meaning the bank can refinance at a lower rate. If so, you'll need to reinvest your money, potentially at a lower rate than before. 

Step-up jumbo CDs

With a step-up CD, the interest rate increases automatically at predetermined intervals during the term with no action required on your part. This can be a good fit if you're comfortable with a lower starting rate in exchange for built-in growth over time. 

Unlike bump-up CDs, you don't need to monitor rate changes and make a request; the increases are scheduled from the outset.

Many savers use jumbo CDs to make large balances work harder. However, there are other alternatives that can offer similar results without such a large initial deposit.

Money market deposit accounts (MMDAs)

Money market accounts typically offer variable interest rates and more flexibility than CDs, as you can usually make withdrawals without penalty. The trade-off is that rates fluctuate with the market, so there’s no certainty of a fixed return.

For savers who want competitive yields but may need some access to their funds, they're worth considering. 

CD laddering 

If you have a large sum and don't want it all locked up at once, a CD ladder can give you the best of both worlds. Instead of putting everything into one jumbo CD, you spread it across multiple CDs with staggered maturity dates.

For example, you can divide your funds between 3, 6, 12, and 24 months. As each one matures, you can reinvest or withdraw.

With Raisin, managing multiple CDs in one place is straightforward. You can build a CD ladder across different partner banks from a single login, keeping your savings organized and fully insured.

Jumbo CDs can be a solid choice for high-balance savers who want a low-risk return and don't need immediate access to their funds. But keep in mind that rates aren't always higher than standard CDs, insurance limits require careful planning above $250,000, and the lack of flexibility may not suit every situation.

Fortunately, you don't need $100,000 to access competitive rates. Through Raisin, you can explore top CD rates from our network of partner banks — often matching or beating jumbo CD rates — with no high minimum required. And because Raisin works with multiple FDIC-insured institutions, spreading your savings to stay within insurance limits is built into how the platform works.
