Basis Point: Explained | TIOmarkets
BY TIO Staff
|July 1, 2024In the world of finance and trading, there are numerous terms and jargon that can seem daunting to the uninitiated. One such term is 'Basis Point'. This term is used extensively in the financial industry, particularly in the context of interest rates and other percentages related to financial transactions. Understanding what a basis point is and how it is used is crucial for anyone involved in trading or finance.
The term 'Basis Point' is often abbreviated as 'bp' or 'bps' (pronounced 'bips'), and is used to denote changes in or differences between interest rates, yields, and other financial percentages. It is a unit of measure used in finance to describe the percentage change in the value or rate of a financial instrument. One basis point is equivalent to 0.01% or 0.0001 in decimal form.
Origins of the Term 'Basis Point'
The term 'Basis Point' has its roots in the financial markets. The word 'basis' in basis point comes from the base or starting point of calculations, while 'point' refers to the smallest measurable unit. The term was created to avoid confusion in discussions about rates and other percentages, and to provide a standard, easily understandable unit of measure.
It's worth noting that the use of basis points is particularly common in the bond market, where even small changes in yield can have significant impacts on prices. Therefore, the use of basis points allows for greater precision in these calculations.
Why Use Basis Points?
Basis points are used because they provide a clear, standardized way of expressing changes in financial rates. This is particularly useful in the world of finance where percentages are often used, and where small changes can have significant impacts. By using basis points, traders and analysts can avoid confusion and ensure that they are speaking the same language.
Moreover, basis points are used to avoid the ambiguity that can arise when discussing changes in percentages. For example, if an interest rate were to increase from 10% to 11%, one could say that the rate increased by 1% or by 10%, depending on whether the change is being described in absolute terms or relative to the initial rate. By using basis points, this ambiguity is eliminated, as the increase would simply be described as a 100 basis point increase.
Application of Basis Points in Trading
In the world of trading, basis points are used in a variety of ways. They are often used to express the change in value of a financial instrument, such as a bond or a derivative. For example, if the price of a bond increases by 1%, this would be described as a 100 basis point increase.
Basis points are also used to express the cost of trading. For example, the bid-ask spread, which is the difference between the price at which a dealer is willing to buy a security (the bid) and the price at which the dealer is willing to sell that security (the ask), is often expressed in basis points. Similarly, the cost of a loan, including the interest rate and any fees, is often expressed in basis points.
Use in Interest Rates
One of the most common uses of basis points is in the context of interest rates. When central banks set monetary policy, they often do so in terms of basis points. For example, if the Federal Reserve decides to raise its target interest rate by 25 basis points, this means that the rate has been increased by 0.25%.
Similarly, in the bond market, yields are often quoted in basis points. A bond yield is essentially the return an investor can expect to receive if they buy a bond and hold it until maturity. If a bond's yield increases from 2.5% to 2.75%, this would be described as a 25 basis point increase.
Use in Exchange Rates
Basis points are also used to express changes in exchange rates. In the foreign exchange market, where currencies are traded, exchange rates can fluctuate by small amounts on a daily basis. These changes are often expressed in basis points, as this allows for a more precise description of the changes.
For example, if the exchange rate between the US dollar and the euro changes from 1.2000 to 1.2050, this would be described as a 50 basis point increase. This means that the value of the euro relative to the dollar has increased by 0.0050, or 0.5%.
Calculating Basis Points
Calculating basis points is relatively straightforward. As mentioned earlier, one basis point is equal to 0.01%, or 0.0001 in decimal form. Therefore, to calculate the number of basis points in a percentage change, you simply multiply the change by 10,000. For example, a 1% change is equivalent to a 100 basis point change.
Conversely, to convert from basis points to a percentage, you divide the number of basis points by 10,000. For example, 100 basis points is equivalent to a 1% change. This simplicity and ease of calculation is one of the reasons why basis points are so widely used in finance and trading.
Example of Basis Point Calculation
Let's consider an example to illustrate how basis points are calculated. Suppose you have a bond with a yield of 5%, and the yield increases to 5.5%. The change in yield is 0.5%, or 0.005 in decimal form. To express this change in basis points, you would multiply 0.005 by 10,000, which gives you a change of 50 basis points.
Now, let's consider the reverse situation. Suppose you are told that the yield on a bond has increased by 75 basis points, and you want to know what this change is in percentage terms. To do this, you would divide 75 by 10,000, which gives you a change of 0.0075, or 0.75%.
Understanding the Impact of Basis Points
While basis points may seem like a small unit of measure, it's important to understand that even small changes in rates or percentages can have a significant impact in the world of finance. This is particularly true when dealing with large sums of money or when these changes compound over time.
For example, a 50 basis point increase in the interest rate on a $1 million loan amounts to an additional $5,000 in interest per year. Similarly, a 50 basis point increase in the yield on a $1 million bond investment would result in an additional $5,000 in income per year. Therefore, understanding basis points can help traders and investors make more informed decisions and better understand the potential impact of changes in rates and yields.
Impact on Loans and Mortgages
One area where basis points can have a significant impact is in the context of loans and mortgages. Interest rates on loans and mortgages are often determined by adding a certain number of basis points to a reference rate, such as the prime rate or the London Interbank Offered Rate (LIBOR).
For example, if the prime rate is 3.25% and a bank offers a loan at a rate of prime plus 200 basis points, the interest rate on the loan would be 5.25%. If the prime rate were to increase by 50 basis points to 3.75%, the rate on the loan would increase to 5.75%. This could significantly increase the borrower's interest payments over the life of the loan.
Impact on Investments
Basis points also have a significant impact on investments. In the bond market, for example, bond prices move inversely to yields. Therefore, a decrease in the yield of a bond by 100 basis points (or 1%) would result in an increase in the price of the bond. This could result in a significant capital gain for the bondholder.
Similarly, in the stock market, a decrease in the dividend yield of a stock by 50 basis points could indicate that the price of the stock is increasing. This could result in a capital gain for the stockholder. Therefore, understanding basis points can help investors make more informed decisions and better understand the potential returns on their investments.
Conclusion
In conclusion, a basis point is a unit of measure used in finance to describe the percentage change in the value or rate of a financial instrument. While it may seem like a small unit of measure, even small changes in basis points can have a significant impact in the world of finance and trading.
Understanding basis points can help traders and investors make more informed decisions, better understand the potential impact of changes in rates and yields, and communicate more effectively with others in the financial industry. Whether you're a seasoned trader or just starting out, a solid understanding of basis points is a valuable tool in your financial toolkit.
