The London Interbank Offered Rate (Libor) is the benchmark interest rate at which major global banks lend to one another in the international interbank market for short-term loans. The rate serves as a globally accepted key benchmark interest rate and is utilized for pricing financial instruments including loans, bonds, and derivatives.
The Libor rate is calculated for five currencies (USD, EUR, GBP, JPY, CHF) and seven different maturities, spanning overnight to one year. It is published daily by the Intercontinental Exchange (ICE).
Historical Context of Libor
Origins of Libor
Libor’s origins trace back to the 1980s, developed as a means for standardizing the interest rates applied in financial transactions among banks. The rate facilitated easier pricing for syndicated loans, which typically involve multiple lenders and complex interest rate calculations.
Libor Scandal
Noteworthy in its history, the Libor rate faced intense scrutiny following the Libor scandal that peaked around 2012. Investigations revealed that several major banks manipulated the rate submissions to benefit their trading positions and financial status, resulting in hefty fines and legal reforms aimed at increasing transparency.
Determining the Libor Rate
Calculation Methodology
Libor is determined through a trimmed mean calculation based on submissions from a panel of leading banks. Each bank estimates the rate at which it could borrow funds before removing the highest and lowest quartiles of the submitted rates and averaging the rest.
LIBOR = \frac{\sum_{i = q + 1}^{n - q} S_i}{n - 2q}
Where:
- \( S_i \) = individual rate submissions
- \( n \) = total number of submissions
- \( q \) = trimming factor (25% of \( n \))
Publication
Rates for different currencies and maturities are published each business day. The publication provides a transparent benchmark that financial markets rely upon for a variety of lending and derivative activities.
Types of Libor Rates
Various Libor tenors and currencies provide flexibility and suitability for different financial instruments:
- Overnight
- One Week
- One Month
- Three Months
- Six Months
- One Year
Each type offers distinct advantages and use cases in financial markets.
Applicability and Significance
Financial Instruments
Libor underpins a wide range of financial instruments such as:
- Loans and Mortgages: Lending institutions often set floating-rate loans and adjustable-rate mortgages based on Libor.
- Bonds and Floating-Rate Notes: Investors use Libor as a reference rate for floating-rate bonds.
- Derivatives: Popular derivatives such as interest rate swaps, futures, and options hinge upon Libor for their pricing models.
Global Finance
Given its pervasive influence, Libor serves not only as a barometer for interbank borrowing costs but also impacts consumer loans, corporate financing, and broader economic activities internationally.
Comparisons with Other Benchmark Rates
Secured Overnight Financing Rate (SOFR)
Libor is often compared with newer benchmarks such as the Secured Overnight Financing Rate (SOFR) advocated in the U.S. as an alternative. SOFR is based on transactions in the Treasury repurchase (repo) market and is seen as a more transparent method since it relies on actual transactional data.
Alternatives in Global Context
- Euro Interbank Offered Rate (Euribor): European counterpart to Libor.
- Tokyo Interbank Offered Rate (Tibor): Japanese variant.
- Shanghai Interbank Offered Rate (Shibor): China’s equivalent.
Future Outlook
Transition Away from Libor
In light of the Libor phase-out announced for the end of 2021 and final cessation by mid-2023, market participants are transitioning to alternative reference rates, especially SOFR in the United States and similar benchmarks globally. This transition is critical for ensuring continuity and integrity in financial contracts previously indexed to Libor.
Regulatory Oversight and Reform
Enhanced regulatory frameworks and standardization practices have been instituted to circumvent issues experienced with Libor, reinforcing market credibility and stability.
Frequently Asked Questions (FAQs)
What is the difference between Libor and SOFR?
Libor is an unsecured lending rate based on bank estimates, while SOFR is a secured rate derived from actual repo market transactions. The transition reflects a move toward greater transparency and reduced manipulation risks.
Why is Libor being phased out?
Libor’s phase-out is due to manipulation scandals and a decreasing number of interbank loan transactions supporting the rate. Alternatives like SOFR provide more robust and reliable benchmarks.
How does the Libor transition affect consumers?
Consumers with loans pegged to Libor may see changes as lenders transition to alternative benchmarks, potentially altering interest rate dynamics.

The Libor rate, once a cornerstone of global financial markets, is a benchmark interest rate at which major banks lend to one another. Despite its extensive influence, it faced controversies due to manipulation, leading to its eventual phase-out. As financial markets adapt to alternatives like SOFR, Libor’s legacy continues to inform ongoing regulatory reforms and benchmarks in the financial industry.
