What Are the Risks of a Certificate of Deposit?

A Certificate of Deposit (CD) is a savings account where a fixed sum of money is held for a predetermined period. Financial institutions offer CDs, allowing depositors to earn interest over this fixed term. The interest rate is typically established at the time of deposit and remains constant throughout the chosen period. CDs are widely regarded as a secure option for managing savings due to their predictable returns and protected nature.

Accessing Funds Before Maturity

Funds in a Certificate of Deposit are committed for a specified duration, known as the CD’s term. Should a depositor need to withdraw money before maturity, they will typically incur an early withdrawal penalty. This penalty serves as a disincentive for breaking the contract and compensates the institution for unexpected liquidity demands.

Early withdrawal penalties vary among institutions but commonly involve the forfeiture of a certain number of months’ worth of interest. For instance, a penalty might be set at three or six months of interest, regardless of how much interest has actually been earned. If the accrued interest is less than the penalty amount, a portion of the original principal may be forfeited to cover the difference. Federal regulations mandate a minimum penalty of seven days’ interest if funds are withdrawn within the first six days of the CD’s term.

While early withdrawal penalties are standard, some exceptions or waivers may apply at the financial institution’s discretion. Common circumstances for a waiver include the death or severe disability of the account holder. Specialized “no-penalty” or “liquid” CDs offer flexibility, allowing withdrawals without penalty; however, these typically come with lower interest rates compared to traditional CDs. Brokered CDs can be sold on a secondary market before maturity, though the sale price could be less than the original investment.

The Effect of Interest Rate Fluctuations

A CD’s interest rate is typically fixed for its entire term, providing a predictable income stream. This fixed rate means the interest earned does not change, regardless of whether market interest rates rise or fall. While this offers stability, it also presents a consideration during periods of economic change.

If market interest rates increase after a CD is purchased, the investor’s funds remain locked into the lower, pre-existing rate. This means the investor misses the opportunity to earn higher returns available on newly issued CDs or other financial products. The existing CD effectively yields less than what could be earned elsewhere, an outcome referred to as opportunity cost.

Reinvestment risk becomes relevant when a CD matures. If, at maturity, market interest rates are lower than the rate the investor previously earned, reinvesting funds will result in a reduced return. This occurs because new CDs or other fixed-income investments will offer less attractive rates. To manage this, some investors use a “CD laddering” strategy, staggering maturities across multiple CDs for periodic reinvestment at current rates, potentially mitigating rate fluctuations.

Inflation and Your Purchasing Power

Inflation, the rate at which prices for goods and services increase, directly impacts money’s purchasing power over time. As prices rise, each unit of currency buys fewer goods and services. This phenomenon is a key consideration for Certificate of Deposit holders, as it can affect the true value of their earnings.

If a CD’s interest rate is lower than the inflation rate, the money held will lose real purchasing power. Even though the nominal amount of money in the account increases due to interest, its ability to buy goods and services at maturity will be diminished. This results in a negative real return, despite a positive nominal return.

This effect is particularly pronounced for longer-term CDs, where funds are locked in for extended periods. Over several years, even a modest inflation rate can significantly erode the real value of fixed interest earnings. Understanding the relationship between a CD’s interest rate and the inflation rate is important for assessing the investment’s true benefit.

Deposit Insurance and Principal Safety

Certificates of Deposit are widely recognized for their high safety, primarily due to federal deposit insurance. For CDs held at banks, the Federal Deposit Insurance Corporation (FDIC) provides this protection. For CDs held at credit unions, the National Credit Union Administration (NCUA) offers comparable insurance through its National Credit Union Share Insurance Fund.

Both the FDIC and NCUA insure deposits up to $250,000 per depositor, per insured institution, for each ownership category. This means the principal amount invested in a CD, along with any accrued interest, is protected up to this limit in the event of a bank or credit union failure. Common ownership categories include individual, joint, and certain retirement accounts.

This comprehensive insurance ensures depositors will not lose their insured funds, even in the rare instance of a financial institution’s insolvency. Since the FDIC’s inception in 1933, no depositor has lost FDIC-insured funds. This robust protection makes CDs one of the most secure options for preserving capital.
