The Government charged the banks €1 billion for the two-year guarantee announced on 30 September 2008. How was this amount arrived at, and does it represent good value for the taxpayer?
According to the Annual Report of the Comptroller and Auditor General issued in September 2009 (available here), the charge of €500 million per year appears to have been calculated as:
{The increase in the cost of funding government debt due to the guarantee}TIMES {The liabilities covered by the guarantee}
The former was set at 0.15%. Liabilities at the end of December 2008, as shown in Figure 23 of the C&AG Report, came to around 345 billion. The product of these two terms comes to around 500 million. (Not an exact match because average rather than end of quarter figures would presumably have been used).
The 0.15% figure comes from the “the advice of the National Treasury Management Agency .. that the cost of funding Government debt would rise as a result of the guarantee by between 0.15% and 0.3%”.
Note that the lower figure was chosen, while many might argue that even the higher value is low, given the extent of the spread over German rates (though part of this is due of course to the budgetary crisis).
Figure 23 of the C&AG Report indicates that the expansion in the Deposit Guarantee Scheme announced on 20 September 2008 (which raised the guarantee per depositor from around €20,000 to €100,000) was not charged for. This would have raised the second term in the equation from 345 billion at end December 2008 to 427 billion. (According to footnote 15, the Deposit Guarantee Scheme is apparently “not regarded as a State guarantee”).
Note also that the charge is based on the cost to the government, not on the value to the banks, which would have been very high. Section 7.23 of the C&AG Report reports however that “account was also taken of the capacity of the covered institutions to pay the charges”!
