What are basis points?

In finance, basis points (BPS) are a unit of measure that communicate small changes in percentages. One basis point equals 1/100 of 1% or 0.01%. Basis points can help express tiny variations in rates or yields that might otherwise be difficult to communicate clearly.

Basis points are commonly used in finance to track changes in interest rates, bond yields, and loan terms, especially when the difference is less than one percent. For example, an interest rate that increases from 3.00% to 3.25% has risen by 25 basis points. This precise measurement helps avoid confusion when discussing miniscule percentage differences.

Basis points are often abbreviated to ‘bps’ or pronounced ‘bips’.

How are basis points calculated?

Calculating basis points is fairly simple. One basis point equals 0.01% or 1/100 of 1%. This means that 100 basis points equals 1%.

Here’s a step-by-step look at how to calculate basis points:

• Convert basis points to a percentage: Divide the number of basis points by 100. For example, 50 basis points equals 0.5% (50 / 100 = 0.5)
• Convert percentages to basis points: Multiply the percentage by 100. For example, 0.25% equals 25 basis points (0.25 x 100 = 25).

Here are some example basis point calculations:

• If a bond yield changes from 3.00% to 3.50%, you could say it rose 0.5 percentage points or 50 basis points (0.5% x 100)
• If the Federal Reserve increased interest rates from 4% to 5%, you could say borrowing rates increased by 1 percentage point or 100 basis points
• If a stock price increases by 3.3%, it is equivalent to 330 basis points (3.3% x 100).

To simplify basis point calculations, consider the conversion table below:

Why do investors and analysts use basis points?

Investors and analysts use basis points to ensure clarity when discussing small but significant changes in financial metrics like interest rates and bond yields.

Avoid ambiguity

Basis points eliminate confusion between absolute and relative percentage changes. For example, if an interest rate has increased from 10% to 11%, some may use the absolute method to say it has increased by 1% while others use the relative method to say it has increased by 10% (10% of 10 is 1).

While both are technically correct, there is room for misinterpretation. Using basis points eliminates this ambiguity by setting a standardized unit of measure – in this case, the interest rate will have increased by 100 basis points.

Describe incremental changes

Basis points are frequently used to communicate fractional shifts, especially when the difference is less than one percent. This can be particularly helpful for expressing minor adjustments that still have material importance.

For example, a Federal Reserve rate hike of 25 basis points means the interest rate has increased by 0.25%. While this may seem like a small adjustment, it can significantly impact borrowing costs and returns on fixed-income investments.

Why are basis points important in financial markets?

Basis points play an important role in financial markets by offering a standardized way to express changes in rates and yields. In finance, small miscommunications over seemingly minor percentage differences can translate to significant discrepancies. Basis points help prevent such misunderstandings by offering a way to clearly communicate percentage changes.

Below are some reasons why basis points are important in financial markets:

• Precision: Basis points offer a precise way to express small percentage changes in financial metrics. This can make measuring changes in bond yields or interest rates more accurate.
• Standardization: Basis points provide a universal method to compare financial metrics. This consistency can help investors analyze the performance of various investments and understand how minor changes can influence returns.
• Trading: Basis points are used to measure the spread between different investments. Traders can use this information to identify potential opportunities for returns by buying low and selling high.
• Investments: Understanding basis points can help investors recognize changes in an asset’s price, yield, or associated fees. For example, a change in a bond yield or fee charged to invest in an ETF can directly affect an investor’s returns.
• Risk management: Investors can use basis points to measure the risk of different investments. By tracking small shifts in bond yields or interest rates, investors can make more informed decisions about how to allocate their portfolios.

For institutional investors managing complex portfolios, basis points play an important role in evaluating asset performance, particularly within prime brokerages.

How basis points communicate interest rate changes

Basis points provide a straightforward and precise way to communicate even the smallest changes in interest rates. They help prevent miscommunication and ensure that borrowers, lenders, and investors are all on the same page. 

To recap, one basis point equates to 0.01%. So if the Federal Reserve raises interest rates by 25 basis points, it means an increase of 0.25%. This clarity is essential when discussing monetary policy or loan rates as even minor changes can have significant effects on borrowing costs and the broader economy.

Financial instruments that use basis points

Here are some examples of financial instruments that use basis points:

• Fixed-income securities: Basis points are used to discuss returns on Treasury bonds and corporate bonds, where even slight shifts in yield can have significant long-term implications.
• Interest rate derivatives: Swaps often use basis points to measure and analyze rate changes.
• Debt securities: Mortgage loans often use basis points to track fluctuations in interest rates.
• Mutual funds & ETFs: Basis points can be used to evaluate the costs of mutual funds and ETFs, providing a clearer understanding of cost differences.
• Stock market derivatives: Futures and options use basis points to measure changes in return rates.

The role of basis points in risk management

Basis points can play a role in risk management by offering a way to measure market risk, analyze credit spread variations, and support stress testing and scenario analysis.

Market risk

Market risk refers to the risk of losses due to changing market conditions. Basis points can be used to evaluate market risk by measuring fluctuations in variables like equity prices, foreign exchange rates, interest rates, and commodity prices. This can help analysts evaluate the volatility of these assets and identify trends in market movements.

Credit spread variations

Credit spreads use basis points to measure the difference in yield between a corporate bond and a comparable government bond. So if a corporate bond yields 4% and a government bond yields 3%, the credit spread is 100 basis points.

The precision of basis points can help risk managers track even minor changes in credit spreads, which can signal changes in credit risk. A wider spread suggests higher credit risk and vice versa. For example, if the credit spread of a corporate bond widens from 150 basis points to 200 basis points, it suggests a perceived increase in the company’s credit risk. This can lower bond prices.

Stress testing & scenario analysis

Basis points are used in stress testing and scenario analysis to simulate the impact of extreme but possible market conditions. For example, a risk manager might model the impact of a 200-basis-point hike in interest rates on a portfolio’s value to identify potential outcomes. They can then adjust the model for even more granular insights (e.g. running the model using a 201-basis-point hike to see how that minor change changes results).

Scenarios using basis points

Below are some examples of how basis points are used in real-world applications.

Investment returns

Institutional investors rely on basis points when analyzing fixed-income investments like bonds. For example, let’s say a bond offers a yield of 2.75% and has increased the yield by 50 basis points. This means the yield is now 3.25%. What initially seems like a minor adjustment actually significantly enhances returns.

Currency exchange rates

Companies involved in international trade know that currency exchange rates can significantly impact profitability. Let’s say a business is converting £700,000 to USD and the exchange rate improves by 20 basis points. While a difference of 0.20% might not seem like a lot, the company could gain hundreds or even thousands in additional value. Monitoring changes in basis points as part of FX risk management can help companies take advantage of these small shifts.

Interest rate hedging

Companies with large debts often hedge against rising interest rates to protect their financial stability. Hedging instruments, like interest rate swaps, are often expressed in basis points. For example, if analysts predict an interest rate hike of 75 basis points, a company might choose to lock in a fixed rate to mitigate the risk of higher borrowing costs.

Loan interest rates

Understanding basis points can be useful when negotiating business loans. For example, if a lender offers an interest rate of 4.45% and agrees to reduce it by 15 basis points, the new interest rate becomes 4.30%. This seemingly minor reduction can save a company substantial amounts in interest payments over the long term.

Credit card rates

Businesses managing cash flow through credit cards often deal with shifting interest rates. While an increase of 50 or 100 basis points in credit card rates might seem minor, it can greatly increase borrowing costs. Knowing how to interpret basis points can allow businesses to compare offers more effectively and choose those with more favorable terms.
