Rates drop sharply following Fed rate cut

19 Sep 2007

BBA LIBOR rates responded to the decision yesterday by the Federal Open Market Committee to cut US rates from 5.25 per cent to 4.75 per cent.

Over the past few weeks, longer term USD BBA LIBOR rates have been setting below the short-term rates, indicating that the market was expecting a cut in interest rates.

Overnight Sterling BBA LIBOR set at 5.8875 per cent today, down from 6.1425 yesterday. Three-month Sterling BBA LIBOR set at 6.55125, down from 6.75. Twelve-month Sterling BBA LIBOR set at 6.28125, down from 6.4125.

Angela Knight CBE, Chief Executive of the British Bankers' Association, said:

"Longer term Sterling BBA LIBOR rates have dropped relative to the shorter term rates, indicating that the UK market may now be expecting the Bank of England Monetary Policy Committee to follow the Fed in cutting rates."

It should be noted that contributors to the BBA LIBOR rates are asked to submit their rates 'just prior to 11.00am', and so these rates should be unaffected by the Bank of England announcement regarding its intention to conduct an auction for funds with three month maturity, which was released shortly after 11.00 today.

Key facts about BBA LIBOR

1. What is BBA LIBOR?

The British Bankers' Association London Interbank Offered Rate closely reflects the real rates of interest being used by the world’s big financial institutions.

Central banks (such as the Bank of England, the US Federal Reserve and the European Central Bank) may fix official base rates monthly, but BBA LIBOR reflects the actual rate at which banks borrow money from each other. BBA LIBOR figures are issued daily on more than 300,000 screens around the world.

Rates are quoted for a range of borrowing periods, ranging from overnight loans to 12 months, and a range of world currencies.

When referring to these rates, please note 'LIBOR' is a generic term, which refers to an individual

Bank’s rate. 'BBA LIBOR' is the benchmark index of London interbank lending. The term LIBOR has been used erroneously to describe this industry standard, but as individual banks may calculate their own Libor rates, the term BBA LIBOR should be used to distinguish them.

2. Why is it in the news?

Because BBA LIBOR rates are calculated daily from the rates at which banks agree to lend each other money, it is a more accurate barometer of how global markets are reacting to market conditions. Recently the overnight borrowing rate has been moving considerably.

3. How is it calculated?

The BBA uses Reuters to fix and publish the data daily, usually before 12 noon UK time. It assembles the interbank borrowing rates from 16 contributor panel banks at 11am, looks at the middle 50 per cent of these rates and uses these to calculate an average, which then becomes that day’s BBA LIBOR rate. This process is followed 150 times to create rates for all 15 maturities (ranging from overnight to 12 months) and all 10 currencies for which a BBA LIBOR rate is quoted.

4. What should I be looking for?

Dramatic changes in the overnight BBA LIBOR rate mean that there is short term volatility in the markets. The overnight rate is the rate which is most often quoted in the financial press. The banks’s longer–term expectations for the markets are more clearly evident in the 12–month figures.

5. How did it become so important?

BBA LIBOR was first developed in the 1980s as demand grew for an accurate measure of the real rate at which banks would lend money to each other. This became increasingly important as London’s status grew as an international financial centre. More than 20 per cent of all international bank lending and more than 30 per cent of all foreign exchange transactions now take place in London.

BBA LIBOR is now used to calculate the interest rates for a range of financial instruments and derivatives based on the BBA LIBOR rates are now traded on exchanges such as LIFFE, the Chicago Mercantile Exchange (CME) and SIMEX. Independent research from Prof. Donald Mackenzie of the Universtiy of Edinburgh estimates that financial derivatives totalling USD 150 trillion are indexed to BBA LIBOR.
