And then on top of it all there is the regulatory tax on risk.
Sir I could not be in more agreement with what Eric De Keuleneer has to say in his letter “Step up competition for banks and rating agencies”, May 12 in relation to taking away the powers the credit rating agencies have been given to distort the markets, as you must know having received at least 100 of my letters on the subject over the last years. That said Mr. De Keuleener does not mention the current tax that the minimum capital requirements for banks impose on risk.
Under the current Basel I Standardized Approach, a low risk corporate loan (rated AAA to AA-) requires a bank to hold only 20% of the basic 8% capital requirement, meaning 1.6 in units of capital, while a much riskier loan (rated below BB-) requires it to hold 150% of the basic 8%, meaning 12 units of capital. If the current cost of capital for the bank is 15%, then the bank's carrying cost for the low risk credit is 0.24% (8%*20%*15%) while the bank's carrying cost for the high risk credit is 1.80% (8%.150%*15%), thereby producing an additional cost of 1.56% that must be added on to the normal spread that the market already requires from the higher risk credit when compared to the lower risk one.
This mind-boggling 1.56 basis points regulatory tax on riskier but frequently more needed credits when compared to low risk but often not so productive loans, dwarves any Tobin tax proposals both in terms of costs and distorting signals, but it is blithely ignored.
