Does It Make Sense To Buy CDs When Interest Rates Are Low?

A certificate of deposit (CD) can be used to fund short-term or long-term goals. When choosing a CD, one of the most important things you might be concerned with is the interest rate your money will earn. Saving in a CD can pay off when rates are higher but what about when rates are low? Evaluating your financial needs and goals can help you decide if opening CD accounts is worth it.

Key Takeaways

  • CD accounts are time deposit accounts that allow you to earn interest on your money for a set maturity period.
  • Banks can use the federal funds rate as a guide when determining where to set CD interest rates.
  • When the federal funds rate increases, CD rates can follow suit, and when the federal funds rate drops, CD rates can dip as well.
  • Whether it makes sense to buy CDs when interest rates are low can depend on your financial goals and needs.

What Is a CD and How Does It Work?

A CD or certificate of deposit is a time deposit account offered by banks, credit unions, and other financial institutions. CDs allow you to deposit money and earn interest over a set maturity term, which may range from 28 days up to 10 years. When the CD matures, you can either withdraw your savings or roll the amount into a new CD.

There are different types of CDs you might open. For example, banks can offer:

Yankee CDs and brokered CDs are two other types of CDs, though they're less common. A Yankee CD is a CD that's offered by a U.S. branch of a foreign bank. Brokered CDs are CD products offered to investors through a brokerage.

CDs enjoy FDIC protection when held at FDIC member banks. The National Credit Union Administration (NCUA) insures CDs at member credit unions. Coverage limits for both types of CDs are the same: $250,000 per depositor, per account ownership type, and per financial institution.


Withdrawing money from a CD before it reaches maturity could result in an early withdrawal penalty.

How Are CD Interest Rates Set?

A CD rate is the interest rate you earn on your savings. When advertising CDs, banks can publish the interest rate and the annual percentage yield (APY). The APY represents the interest earned annualized over a period of one year. Most of the time, the interest rate for a CD and a CD's APY are the same.

Banks can use a benchmark rate to set CD rates. In many cases, the rate used is the federal funds rate. This is the rate at which banks lend money to one another overnight. The Federal Reserve, also known as the Fed, is responsible for making adjustments to the federal funds rate in order to manage monetary policy in the U.S.

When the Fed raises the federal funds rate, banks and credit unions may raise rates offered on deposit accounts, including CD accounts. If the Fed cuts rates, banks can reduce rates offered on CDs and other deposit accounts.


Banks can set interest rates for individual CD products based on the maturity term, with longer-term CDs generally earning higher rates.

Does It Make Sense to Buy CDs When Rates Are Low?

If you're considering saving money in a CD, getting the best rate possible might be a priority. When interest rates are low, CDs can lose some of their appeal for savers, as they can offer less potential for growth overall. You may have even less incentive to park some of your money in CDs if you expect interest rates to rise in the near future.

Whether you should buy CDs or not, regardless of rates, can depend on your needs and goals. If you've maxed out your emergency fund, for example, and are saving for retirement in a 401(k) or IRA, you might have money to spare. A CD could offer a safe and secure place to keep that money until you need it and allow you to earn a little interest in the bargain.

On the other hand, if you need more flexibility with your money and want to get a higher rate, you might consider a high-yield savings account or money market account instead. These accounts can allow you to make up to six withdrawals per month and may feature more competitive rates than what CDs offer.


Online banks may offer better CD rates and savings account rates than traditional banks or credit unions.

Combat Low Rates With CD Laddering

If you're concerned about low CD rates limiting your savings growth, you may consider building a CD ladder. A CD laddering strategy involves buying multiple CDs with different maturity terms and interest rates. This approach offers two advantages.

First, by laddering CDs with different maturity terms, you're better able to keep pace with changing interest rates. Say you open three CDS: a three-month, a six-month, and a nine-month. Two months after opening them, rates go up. You can take advantage of that by rolling the three-month CD into a new CD once it matures.

Laddering can also help you to avoid early withdrawal penalties if a maturity date is always on the horizon. Once one of the CD "rungs" on your ladder matures, you can decide whether to withdraw the money or deposit it into a new CD. And again, if rates have risen since you opened the CD originally, you can capitalize on that increase.

Are CDs a Good Investment?

CDs can be a good investment for people who want a safe and secure place to save money they don't plan to spend right away. It's virtually impossible to lose money with bank-issued CDs and the rate of return is more or less guaranteed. The only time you might face risk with CDs is if you're investing in Yankee CDs or brokered CDs.

Which Bank Has the Best CD Rates?

Banks are constantly updating CD rates, so it can be difficult to find just one that offers the highest rates. In general, you're more likely to find higher CD rates at online banks versus traditional banks and credit unions. Online banks may also have lower minimum deposit requirements for CDs.

Why Do CD Rates Change?

CD interest rates are not static and banks can change them to keep pace with changes to the federal funds rate. When the federal funds rate goes up, then banks can raise CD rates. If the federal funds rate goes down, banks and credit unions may cut CD rates.

The Bottom Line

Should you invest in CDs when rates are low? It may still be a good move if you're opening CDs to meet short-term needs. If rates rise later, you could roll the money over into a new CD to earn more interest until you're ready to spend it. When deciding where to open a CD account, take time to compare the best CD rates. Also, look at the different maturity terms and types of specialty CDs a bank may offer to find the savings option that's best for you.
