The U.S. dollar, the euro, the British pound, the Japanese yen, and the Swiss franc are the five currencies on which LIBOR is based.
The seven different maturities of LIBOR are overnight/spot next, one week, and one, two, three, six, and 12 months.
There are a total of 35 different LIBOR rates calculated and reported each business day which comes from the combination of five currencies and seven maturities.
The three-month U.S. dollar rate is the most commonly quoted rate and is usually referred to as the current LIBOR rate.
Every day, major global banks are asked by ICE, as to how much they would charge for short-term loans to other banks.
The highest and lowest figures are taken, then the average is calculated from the remaining numbers. This is called a trimmed average.
Then each morning this rate is posted as the daily rate.
It is never a static figure. After calculating the finalized rates for each maturity and currency, the ICE Benchmark Administration (IBA) announces and publishes once a day at 11:55 a.m. London time.
Since LIBOR is also the basis for consumer loans in countries around the world, it affects consumers in the same manner as it does financial institutions.
The interest rates on credit cards, car loans, and adjustable-rate mortgages fluctuate based on the interbank rate.
