There have been a few
suggestions that homeowners with mortgages may have lost out because of the
attempted manipulation by Barclays dealers of the LIBOR rate between 2005 and
2010.
I think you have to
be careful with this because:
*Only a small
proportion of mortgages are directly linked to LIBOR, perhaps 250,000 loans to
buy-to-let borrowers and some to sub-prime customers.
*As for other
variable rate mortgages, LIBOR could influence a lender's cost of funds but the
impact is less direct.
*It appears that
before the credit crunch banks may have been over-quoting and under-quoting
LIBOR in order to make dealing profits. In theory this could have pushed some
people's mortgage costs slightly higher or slightly lower.
*However the more
significant attempts at manipulation may have come after the credit-crunch,
from 2007, when under-quoting appears to have been the main problem. If that
had any impact at all it would have been to reduce the cost of variable-rate
mortgages.
*From that point, in
any case, lenders were having to depend much more heavily on savers' deposits
to fund mortgages, because they couldn't raise money in the financial markets
where LIBOR is a key reference rate - so LIBOR became less important for
mortgage rates.
Mortgage experts
suggest the net effect of the shenanigans could well have been to lower
people's mortgage costs - though that might not be true for all customers
throughout the period.
If that's true, the
real victims would be the institutions who deposit money with banks for short
periods at rates which are linked to LIBOR - pension funds, local authorities,
hedge funds and private equity firms.
If LIBOR was
manipulated down, they would have have lost out directly.
