What Was the London Interbank Bid Rate (LIBID)?

The London Interbank Bid Rate (LIBID) was the average interest rate at which major London banks bid for eurocurrency deposits from other banks in the interbank market. It was the bid rate that banks were willing to pay for eurocurrency deposits and other banks' unsecured funds in the London interbank market, while the more popular LIBOR was the offered rate.

Eurocurrency deposits refer to money in the form of bank deposits of a currency outside that currency's issuing country. They may be of any currency in any country.

As a result of the LIBOR rate fixing scandals, LIBID was phased out along with LIBOR beginning in 2021.

Understanding the London Interbank Bid Rate (LIBID)

The London Interbank Bid Rate (LIBID) was the other side of the more famous London Interbank Offered Rate (LIBOR). Whereas LIBOR was the "ask" rate at which a bank is willing to lend eurocurrency deposits to another bank, LIBID was the "bid" rate at which banks are willing to borrow.

The difference between the two is the bid-ask spread on these transactions. When LIBID was high, it meant that borrowers were seeking to borrow funds with increasing demand.

While LIBOR was a popular benchmark interest rate that was calculated and published by Intercontinental Exchange (ICE), LIBID was not standardized or publicly available. It was not used outside of the interbank lending market. The most common currency deposited as eurocurrency is the U.S. dollar. For example, if U.S. dollars are deposited in any bank outside the U.S.—for example, in Europe or the U.K.—then the deposit is referred to as a eurocurrency (eurodollars in this case).

The Difference Between LIBID and LIBOR

Both LIBID and LIBOR were reference rates set by banks in the London interbank market. The London interbank market is a wholesale money market in London where banks exchange currencies either directly or through electronic trading platforms.

Starting in the 1970s, LIBOR was the benchmark rate for interbank lending and is calculated for seven maturities for five currencies: the Swiss franc, the euro, the pound sterling, the U.S. dollar, and the Japanese yen. Before LIBOR fell out of use, there were 35 different LIBOR rates released to the market every day.

How the LIBID Rate Was Used

Until the rate-fixing scandal, both of these rates (especially LIBOR) were considered the foremost global reference rates for short-term interest rates of a variety of global financial instruments such as short-term interest futures contracts, forward rate agreements, interest rate swaps, and currency options. LIBOR was also a key driver in the eurodollar market and is the basis for retail products like mortgages and student loans. They were derived from a filtered average of the world's most creditworthy banks' interbank bid/ask rates for institutional loans with maturities that range between overnight and one year.

The London Interbank Mean Rate (LIMEAN) is the calculated average between LIBOR and LIBID and could be used to identify the spread between the two rates. LIMEAN was also used by institutions borrowing and lending money in the interbank market (rather than using LIBOR or LIBID) and it was a reliable reference to the mid-market rate of the interbank market.

The Bottom Line

LIBID was an interbank reference rate used to measure the cost of borrowing money between different banks. Along with LIBOR, it was frequently used in variable-rate mortgages and contracts to measure the changing costs of borrowing money. LIBID and LIBOR were phased out in 2021 and replaced by the Secure Overnight Financing Rate (SOFR).
