ToughDaddy - What do you do in RL? I'm asking because you suggest you work in finance and yet you say things that leave me scratching my head, like:
"banks could KEEP the same margins if Libor moved in line with BoE rate. And at the same time reduce the default rates of businesses."
LIBOR has nothing to do with rate of default of businesses, who do not borrow at LIBOR.
Banks' lending rates to businesses and persons will not decrease in line with BoE rates either, because risk premiums have gone up not only because banks realised they can't lend to anyone and everyone, but also because we are in a recession and borrowers are more likely to run into problems and go bankrupt and hence be unable to pay back their debts.
" they need reduce libor in line with BoE rate like it used to. But that is not happening on the "free mkt", hence intervention by the govt."
LIBOR has decreased in response to lower BoE rate, but it is naive to expect this decline to be proportional.
And there has been no 'intervention' to LIBOR by the government, and there can't be one while the 16 bank that determine it are private entities, so what are you talking about?
