As some of you may know, I'm not averse to putting a boot into Labour, and especially Gordon Brown, but in this instance, I think it's all a big storm in a teacup and is probably best forgotten.
Here's why. Firstly, back in 2008 all the banks stopped lending to each other as each bank was fearful that other banks would go bust and take them down with it. In this instance, with no money actually being lent out, it doesn't really matter what you set (or even fiddle) the interest rate to - 1%, 10% or even 1,000,000% - no one is lending and no one is borrowing. Does manipulating the rate really matter in this instance? The answer is no.
Secondly, as has been pointed out, manipulation of LIBOR can affect mortgages. It should be pointed out that most (i.e. nearly all) tracker mortgages follow Bank of England rates rather than LIBOR (which is a very different thing), so the overall number of peoples mortgages affected is low and in any case, these mortgages would have been reduced by this measure, not increased. The flip side of this is that savers would have got lower interest rates, but as the BoE interest rates were falling all the time and, at this point, were nearly through the floor, would a short term manipulation of the LIBOR rate have much of an effect? The answer is that any effect on mortgage holders would be negligibly beneficial and any effect on savers would be negligible, albeit in a negative direction.
Finally, and this is the clincher for me, what may have happened if Barclays hadn't manipulated the rates? Well, firstly, they may have gone bust and required a bailout from you and me, the taxpayer. As it was, they were able to get a bunch of rich Arabs to bail out the company. This has saved the taxpayer many billions of pounds, and for that reason, I think that doing what they have been accused of doing, was probably a good thing.
As I said, there's nothing to see here. This is the Tories trying to smear Labour in the same way as Labour has smeared the Tories over the Sky TV takeover.
