We explain Libor, its relationship with the bank rate and why it is so important in the credit crunch and for influencing mortgage pricing...
Commentary: The three-month sterling Libor rate fell from 2.65% to 2.61%, announced at 12.00pm on Tuesday, as expectations heightened of a substantial Bank of England rate cut this week and banks eased their lending following the year's end.

The UK bank rate was cut from 3% to 2% in early December but it has taken time for Libor to factor in that cut. The initial reduction was, proportionately, far less than after the previous rate cut.
In November, the bank rate was cut by 150 basis points and 107 points were shaved off Libor by the following day. This time, only 38 of the 100 points were immediately passed on.
Experts have suggested a significant narrowing of Libor vs bank rate will come in the New Year, as banks stop hoarding cash before year end. Financial results for banks, struck on 31 December, would then be able to show stronger cash balances. Alex Potter of broker Collins Stewart warned in the Mail on Sunday (9 Nov): 'Last year Libor fell sharply at the end of December and by mid-January it had fallen in line with the base rate. I would expect something similar to happen this year.'
The Libor rate so far this year:
The key three-month sterling Libor rate started the year marginally above 5.5% - broadly equal to the bank rate. It then climbed higher as the extent of the credit crunch emerged. It peaked at 6% in early April, despite the bank rate falling to 5% by that month, and then drifted down throughout the summer to a low of 5.7% on 12 September. A dramatic worsening of the crisis sent it up to 6.3% on 30 September (a 130-point gap with the bank rate). It has since plunged (see below) to factor in a fall in the bank rate from 4.5% to 2% but remains substantially higher than the bank rate.

What is Lib
It is the London Inter-Bank Offered Rate - the rate at which international banks lend to each other. It is calculated every business day in 10 currencies and 15 timespans, ranging from overnight to one year and is based on the level at which banks have been lending to each other.
When is it set?
It is set and announced at around 11am to midday for the UK rate, based on borrowing from the previous day. Operating since the mid-1980s, in the years before the credit crunch it sat marginally higher than the central bank ra
'Undercover Economist' Tim Harford attempted to cut through the secrecy behind the compilation of Libor on his Radio Four show More or Less (14 December 2008): Listen here on the iPlayer (skip to 18 mins 20 secs) | More about the show
Why is it important?
It influences the level at which lenders set rates on loans, especially mortgages, to consumers and to businesses. It also impacts on the amounts they will lend. It is the rate at which banks lend to each other and is therefore a measure of how much they trust each other and a measure of the credit crunch. There tends to be a lag from when Libor changes to when bank lending rates are altered.
Also, mortgage deals have increasingly been linked to Libor rather than bank rate or a lender's SVR. That's because it is more closely linked to a lenders' costs.
What would Libor be in 'normal' conditions?
The three-month Libor rate should be just 10 or 20 basis points higher than the bank rate if conditions went back to how they were in the first half of this decade. So under pre-credit crunch conditions, if the bank rate or base rate is 2%, Libor should be 2.1% or 2.2%. But it soared far higher in August 2007, marking the start of the credit crunch. It recovered over the summer of 2008 (see the figures above) as some trust returned but then spiked on the collapse of Lehman Brothers (15/16 Sept 2008).
But shouldn't bank bailouts help bring down Libor?
That's the idea. But news of the $700bn US bank bailout failed to move Libor in the UK and it actually rose, heading above 6%. However, the UK's £40bn cash injection into banks on 13 October appeared to have had a positive but moderate effect with rates easing.

As the banks have not been willing to lend to each other for months,in effect LIBOR has been used as a completely ficticious form of base rate to justify increasing/ maintaining mortgage rates. As one friend put it to me - " Libor is the rate banks no longer lend to each other at!"

Question-can the banks take the money and not start lending again, as all the mortgage deals and lending criteria have gone up since the bail out, and what about the trillions of debt on the insurance payout if firms go bust- oh dear, Gordon and chums have not mentioned this elephant in the room!

Only those with big lumps of equity (read cash) will be given the best rates when mortgages finally come down in cost. The banks will need to cover themselves by at least 30 percent to allow for a depreciating market and will repossess very quickly in the event of default to protect their investment before prices fall further. Thus, ironically, precipitating a further collapse in the price of housing. Also, if investors do not receive a premium over the rate of inflation there will be a flight from Sterling making it even harder for the banks to lend with certainty. Confidence in the housing market and banking is shot to bits and will probably take several years to recover. House prices must fall, debt must be repaid and bank balances put back in the black before any kind of recovery can take place. Excessive Government borrowing whilst shoring things up in the short term will extend the long term recovery by a considerable margin.

The suggestion in this article that libor should always be 10-20bp over the base rate is erroneous. If the short term yield curve is sloping upwards then yes 3m Libor will be higher than the base rate but in the UK's case the short term curve slopes sharply downwards in the near term, meaning that 3m Libor should actually be below the base rate, not 158bp above it which it currently is! This fact demonstrates the extent of the current inter banking deep freeze.
