# What Is a Basis Point? Definition and How to Use

September 4, 2024

If a lender informs you that the interest rate on a 30-year adjustable-rate mortgage (ARM) went up by 50 basis points, the rate might go from 5.50% to 6.00%. Taking those numbers into account, 10 basis points—abbreviated as bps—amount to 0.10%, 25 basis points add up to 0.25%, 50 basis points are equal to 0.50%, 75 basis points mean 0.75% and 100 basis points make 1.00%. BPS and PVBP are just two of the ways in which you can evaluate different investment options. You may consult a qualified financial advisor to guide you in making more informed investment decisions.

## What is the approximate value of your cash savings and other investments?

The term “basis point” has its origins in trading the “basis” or the spread between two interest rates. Since the basis is usually small, these are quoted multiplied up by 10,000, and hence a “full point” movement in the “basis” is a basis point. In 2022, the FOMC approved seven hikes in the federal funds rate, with each being 25, 50 or 75 basis points. This is the Fed’s benchmark interest rate, used to determine how much one bank pays another bank for overnight loans.

We believe everyone should be able to make financial decisions with confidence. For example, they might analyze the effect of an interest rate increase of 200 basis points on the portfolio’s value. They then can refine that model to as fine of a level as they want (i.e. they can adjust to 201 basis points to see how that minute change can impact models).

## What Is a Basis Point (BPS)?

Most price changes will happen around the basic unit of 0.01 points and most negotiations begin with that as the lowest common denominator up for discussion. It’s like understanding that prices will be negotiated in dollars, rather than quarters or dimes. Interest rates for other lending products, including fixed-rate mortgages and some student loans, tend to go up or down depending on the movement of SOFR.

Basis points can also generally be used as part of risk management techniques. Though some of the following points may seem intuitive after reading the article above, it’s a worthwhile callout to note that small changes in basis points can tell more information than just a change in percent. By using basis points in the conversation, traders and analysts remove some of the ambiguity or confusion that can arise when talking about percentage moves.

After a year, the interest rate was lowered by 60 BPS, so newly issued bonds only pay 1.9%. Basis points are also used when referring to the cost of mutual funds and exchange-traded funds (ETFs). For example, a mutual fund’s annual management expense ratio (MER) of 0.15% will be quoted as 15 bps. Instead of using a 100 basis point change, the price value of a basis point simply uses a one basis point change. It does not matter if there is an increase or decrease in rates because such a small move in rates will be about the same in either direction. If you start with a decimal and want the figure in percentage form, multiply by 100.

Although basis points are used primarily when referring to yields and interest rates, they may likewise refer to the percentage change in the value of an asset such as a stock. For example, an analyst may describe how a stock index rose 134 basis points throughout the trading day. People use the terms “basis points” and “percentage points” to avoid confusion when discussing the difference between the two rates.

It helps avoid confusion when dealing with small numbers, such as when calculating percentage changes in yields, spreads, or interest rates. Oftentimes, traders will use basis points to refer to the change in value of a security or when comparing the rates on different securities. For example, you may hear the term used when yields on corporate bonds and treasury securities are compared.

1. The prevalence of the term underscores just how massive financial transactions have become and, thus, why even seemingly microscopic changes in yield can render or ruin fortunes.
2. Therefore, to move from bps to percentages, we divide by 100, and to switch from percentages to bps, we must multiply by 100.
3. This metric is commonly used for loans and bonds to signify percentage changes or yield spreads in financial instruments, especially when the difference in material interest rates is less than one percent.
4. Our partners cannot pay us to guarantee favorable reviews of their products or services.
5. Beyond markets, they’re very often used to describe percentage amounts even for non-financial purposes.

Basis points also help when discussing incremental changes in a yield, such as a bond interest rate. Suppose you invested \$1,000,000 in a government bond with 2.5% interest.

Yields fluctuate, in part because of prevailing interest rates, which are set by the Federal Reserve’s Open Market Committee. If the Fed lowers its fed funds target rate, interest rates on newly issued bonds will decline, and vice versa. Those changes affect the prices that investors are willing to pay for older bonds, which affects the expected return on the bonds. Like percentage points, basis points avoid the ambiguity between relative and absolute discussions about interest rates by dealing only with the absolute change in numeric value of a rate.

We’re moving the decimal in the percentage to the right by two places, but we must be careful not to multiply by 100% or 1, as the resulting amount will be equal to the percentage. While 1/100th of 1.0% might initially sound like a minuscule difference, the economic implications and impact on yields can be substantial.

So, if the FOMC hikes the federal funds rate, the APY for a high-yield savings account might rise 75 basis points, from 4.25% to 5.00%. A basis point is 1/100th of 1% and is commonly used to indicate interest rates or changes in rates in bonds and other financial instruments. Basis Points (bps) represent a unit of measurement for interest rates in finance and are equal to 1/100th of 1.0%. The term “basis points” is most often used when discussing the interest rate environment such as the Fed or in reference to bonds and fixed-income securities.

In May 2023, the Federal Open Market Committee (FOMC) increased the benchmark interest rate by 25 basis points, or 0.25 percentage points, to a range of 5% to 5.25%. The Federal Reserve’s benchmark rate is the Effective Federal Funds Rate, which is the effective rate at which banks borrow funds from each other overnight. This rate is governed by the Federal Fund Rate Target Range set by the Federal Reserve. Suppose you’re a mutual fund or exchange-traded fund (ETF) investor. In that case, you may encounter an annual fee called an “expense ratio,” which is the portion of assets deducted each year by your fund manager for fund expenses.

The credit spread, measured in basis points, reflects the perceived credit risk of the bond issuer. The word basis in the term basis point comes from the base move between two percentages, or the spread between two interest rates. Since the changes recorded are usually narrow, and because small changes can have outsized outcomes, the basis is a fraction of a percent. The increase from 10% is either 50 basis points (which is 10.5%) or 500 basis points (which is 15%).

Market risk, or the risk of losses due to changes in market conditions, can also be assessed using basis points. Fluctuations in market variables such as equity prices, foreign exchange rates, and commodity prices can be measured in basis points. In the bond market, basis points are used when referring to the yields that fixed-income instruments pay investors.

For example, suppose that the yield on a bond rose by 0.5% from 7.5%. While points are most often used when talking about percentages, they are also sometimes used when talking about prices. If a trader says, for example, that the price of a stock declined by 15 points, he may mean that the stock lost \$15 off of its value. However, using the term points in this way can lead to confusion, as other investors may not be able to tell whether you are referring to the underlying value of an asset or the percentage amount by which it has changed. You’ll also see or hear basis points cited when people are talking about things like savings accounts, interest-bearing checking accounts, certificates of deposit (CDs) and money market accounts. Basis points are often used to describe a change in value with regard to these instruments.

Working with an adviser may come with potential downsides such as payment of fees (which will reduce returns). There are no guarantees that working with an adviser will yield positive returns. The existence of a fiduciary duty does not prevent the rise of potential conflicts of interest. Even minor changes to an investment asset can cause significant shifts in market value.
