Contributing Factors
Subprime mortgages
o Risky bank loans and mortgages
o Government securities backed by subprime mortgages
o Means that borrowers had poor credit histories
o Asymmetric information as banks did not know how risky the loans were
o Banks make sure you can afford to pay back your loan
Moral hazard
o There is a risk that the borrower does the things that the lender would not deem
desirable
o Makes the borrower less likely to repay the loan
o Usually occurs when there is some form of insurance for the mistake
o Banks may take risks if they know the BoE will bail them out
o Systematic risk can be seen as a negative externality.
Speculation & market bubbles
o Occurs when a price of an asset is predicated to rise significantly
o Causes it to be traded more, demand exceeds supply
o Price rises beyond intrinsic value
o The bubble burst when the price steeply falls to original level
o Causes panic and investors try to sell their assets
o Loss of confidence leads to economic decline or a depression
Role of banking regulation
o Government might regulate banks with regulation & guidelines
o Ensure their behaviour is clear
