How Is Libor Calculated: A Comprehensive Guide
LIBOR, or the London Interbank Offered Rate, is a benchmark interest rate that is used globally to determine the cost of borrowing for various financial products. LIBOR is calculated daily by a panel of major banks in London, who estimate the interest rates at which they could borrow funds from each other in various currencies and for different time periods. The rate is then published by the Intercontinental Exchange (ICE) at approximately 11:45 EST each day.
The LIBOR rate is used as a reference rate for a wide range of financial products, including mortgages, loans, and derivatives contracts. As such, it is a critical component of the global financial system. However, there has been some controversy surrounding the calculation of LIBOR, particularly in the wake of the 2008 financial crisis. Some banks have been accused of manipulating the rate in order to benefit their own trading positions, leading to fines and regulatory scrutiny. In response, efforts have been made to reform the calculation of LIBOR and to transition to alternative benchmark rates.
Overview of LIBOR
Definition of LIBOR
The London Interbank Offered Rate (LIBOR) is a benchmark interest rate that represents the average interest rate at which major banks in London can borrow unsecured funds from other banks in the London interbank market. LIBOR is calculated and published daily for five currencies (USD, GBP, EUR, CHF, and JPY) and seven maturities (overnight, one week, one month, two months, three months, six months, and twelve months). It is widely used as a reference rate for financial contracts such as loans, bonds, derivatives, and mortgages.
Historical Context
LIBOR was first introduced in 1984 by the British Bankers’ Association (BBA) as a way to standardize the interest rates at which banks lend to each other. The BBA collected daily rate submissions from a panel of banks and calculated an average rate based on the submissions. Over time, the number of banks on the panel grew, and the methodology for calculating the rate was refined.
In 2012, LIBOR came under scrutiny when it was discovered that some banks on the panel had manipulated their rate submissions to benefit their trading positions. This led to regulatory investigations and fines, and ultimately to a decision to phase out LIBOR by the end of 2021. The Financial Conduct Authority (FCA) took over the administration of LIBOR from the BBA in 2013 and has been working with market participants to transition to alternative reference rates such as the Secured Overnight Financing Rate (SOFR) in the US and the Sterling Overnight Index Average (SONIA) in the UK.
LIBOR Calculation Methodology
Data Collection
LIBOR is calculated based on daily submissions from a panel of major banks. These banks estimate the interest rates at which they could borrow funds from each other in various currencies and tenors. The panel banks are selected by the Intercontinental Exchange (ICE) Benchmark Administration, which is responsible for overseeing the LIBOR benchmark.
Currency and Tenor Variations
LIBOR is calculated for five currencies: US dollars, British pounds, euros, Swiss francs, and Japanese yen. For each currency, there are seven different tenors, ranging from overnight to 12 months. As the length to maturity increases, the LIBOR rate also tends to increase.
Trimming Process
To ensure the accuracy and reliability of the LIBOR benchmark, the highest and lowest 25% of submissions are excluded from the calculation. This process is known as “trimming”. The remaining submissions are then averaged to produce the daily LIBOR rate for each currency and tenor.
It is important to note that the LIBOR benchmark is currently being phased out and is expected to be discontinued by the end of 2021. The replacement benchmark is the Secured Overnight Financing Rate (SOFR), which is based on overnight loans collateralized by US Treasury securities.
Panel Banks and Contributions
Selection of Panel Banks
The LIBOR panel banks are a group of banks that are selected by the Intercontinental Exchange (ICE) to contribute to the calculation of LIBOR. The selection of panel banks is based on several criteria, including the bank’s reputation, its size, and its ability to provide accurate and reliable data.
The current panel of banks that contribute to the USD LIBOR rate consists of 18 banks, including Bank of America, Barclays, Citigroup, and JPMorgan Chase. The panel banks are required to meet certain criteria, such as having a significant presence in the USD LIBOR market and being able to provide data that is representative of the market.
Contribution Criteria
Each panel bank is required to submit its estimate of the cost of borrowing funds in the interbank market for a set of maturities and currencies. The banks are asked to submit the rates at which they would be able to borrow funds in the interbank market, without providing any collateral.
The contributions are made based on the USD LIBOR Panel Bank Criteria, which are designed to ensure that the contributed input data is able to produce a rate that is representative of the economic reality. The criteria include requirements related to the size of the bank, its reputation, and the quality of its data.
The submitted rates are then used to calculate the LIBOR rate for each maturity and currency. The rates are trimmed to remove the highest and lowest 25% of contributions, and the remaining rates are averaged to determine the final LIBOR rate.
In summary, the selection of panel banks and the contribution criteria are designed to ensure that the LIBOR rate is calculated using accurate and reliable data that is representative of the market.
Regulatory Oversight and Governance
Regulatory Bodies
The regulatory oversight of LIBOR is a complex process that involves multiple regulatory bodies. The primary regulatory body responsible for overseeing LIBOR is the Financial Conduct Authority (FCA) in the UK. The FCA is responsible for ensuring that LIBOR is calculated and published in a fair and transparent manner. In addition to the FCA, other regulatory bodies such as the US Commodity Futures Trading Commission (CFTC) and the European Securities and Markets Authority (ESMA) also play a role in regulating LIBOR.
Governance Framework
The governance framework for LIBOR is overseen by the Intercontinental Exchange (ICE) Benchmark Administration (IBA). The IBA is responsible for the day-to-day administration of LIBOR, including the calculation and publication of the benchmark. The IBA is also responsible for ensuring that the governance framework for LIBOR is robust and transparent.
The governance framework for LIBOR consists of various committees and working groups. These include the LIBOR Oversight Committee (LOC), which is responsible for overseeing the overall governance of LIBOR, and the LIBOR Code of Conduct Working Group, which is responsible for developing and maintaining the LIBOR Code of Conduct.
The governance framework for LIBOR also includes a number of policies and procedures designed to ensure the integrity of the benchmark. These include policies on conflicts of interest, data quality, and the use of expert judgment in the absence of sufficient market data.
Overall, the regulatory oversight and governance of LIBOR is a complex process that involves multiple regulatory bodies and a robust governance framework. The goal of this oversight is to ensure that LIBOR is calculated and published in a fair and transparent manner, and that the benchmark remains a reliable and accurate indicator of the cost of borrowing in the interbank market.
Adjustments and Corrections
Error Handling
Errors can occur during the calculation of LIBOR, which can affect the accuracy of the benchmark rate. In order to minimize the impact of such errors, the ICE Benchmark Administration (IBA) has established a robust error-handling process. The IBA has implemented various measures to prevent errors, such as automated data checks and manual data reviews. If an error is detected, the IBA will investigate and rectify it as soon as possible.
Post-Publication Corrections
Even after publication, errors in the LIBOR calculation can be identified. In such cases, the IBA has established a process for correcting the published rates. Corrections are made by publishing the correct rate alongside the incorrect rate. The incorrect rate is then removed from the system after a specified period of time.
In addition to errors, the IBA may also make adjustments to the LIBOR calculation methodology. Such adjustments may be necessary due to changes in market conditions or to ensure the accuracy of the benchmark rate. The IBA has established a transparent process for making such adjustments, which involves consultation with market participants and regulators.
Overall, the IBA’s error-handling and correction processes, as well as its methodology adjustment process, help to ensure the accuracy and integrity of the LIBOR benchmark rate.
Transition from LIBOR
As of January 1, 2022, the four non-U.S. dollar LIBOR benchmark rates—the British pound (GBP), Japanese yen (JPY), Swiss franc (CHF), and euro (EUR)—along with the one-week and two-month U.S. dollar LIBOR benchmark rates have been discontinued. The remaining tenors of U.S. dollar LIBOR are scheduled to cease publication after June 30, 2023 [1].
Alternative Reference Rates
The Alternative Reference Rates Committee (ARRC) in the United States has recommended the Secured Overnight Financing Rate (SOFR) as the replacement for LIBOR. SOFR is based on actual overnight repurchase agreement transactions and is considered to be a more reliable and transparent benchmark rate. Other countries have also identified their own alternative reference rates, such as the Sterling Overnight Index Average (SONIA) in the UK and the Euro Short-Term Rate (ESTR) in the Eurozone [1].
Impact on Financial Contracts
The transition from LIBOR to alternative reference rates will have a significant impact on financial contracts that reference LIBOR. To address this, many financial institutions are amending their contracts to include fallback language that provides for the replacement of LIBOR with an alternative reference rate in the event that LIBOR is no longer available. However, the transition may still be challenging for some contracts, particularly those that are more complex or have longer maturities. Financial institutions are also working to develop new products and services that are based on the alternative reference rates [2].
Overall, the transition from LIBOR to alternative reference rates is a significant change for the financial industry. While there may be challenges in the short term, it is expected to result in a more reliable and transparent benchmark rate system in the long term.

Frequently Asked Questions
What factors are considered in the calculation of LIBOR?
LIBOR is calculated based on the average mortgage payment massachusetts interest rate at which a group of banks can borrow funds from other banks in the London interbank market. The rate is calculated based on a number of factors, including the creditworthiness of the banks involved, the term of the loan, and prevailing market conditions.
How do banks contribute to the determination of LIBOR rates?
Banks contribute to the determination of LIBOR rates by submitting their borrowing rates to the ICE Benchmark Administration (IBA) each day. The IBA then calculates the average of the rates submitted by the banks to arrive at the LIBOR rate for that day.
What methodology is used to calculate the 3-month LIBOR rate?
The 3-month LIBOR rate is calculated using a methodology that is based on the submissions of a panel of banks. The IBA calculates the rate by taking the average of the rates submitted by the banks, after removing the highest and lowest 25% of the submissions.
In what ways can the LIBOR rate be calculated using Excel?
The LIBOR rate can be calculated using Excel by using the “RATE” function. This function can be used to calculate the interest rate for a given period based on a series of cash flows. However, it is important to note that the rate calculated using Excel may not be the same as the official LIBOR rate.
What are the key differences between SOFR and LIBOR in rate calculation?
The key difference between SOFR and LIBOR in rate calculation is that SOFR is based on actual transactions in the overnight repurchase market, while LIBOR is based on the average borrowing rates submitted by a panel of banks. This makes SOFR a more reliable benchmark, as it is based on actual market transactions.
Since LIBOR is being phased out, what benchmark is taking its place?
The benchmark that is taking the place of LIBOR is the Secured Overnight Financing Rate (SOFR). SOFR is a benchmark that is based on actual transactions in the overnight repurchase market and is considered to be a more reliable benchmark than LIBOR.
