(3) Neglected Problems
To sum up:
- Basel III relies on quantitative measures to enhance the balance sheets of banks with a strong concentration on the capital base.
- Structural (systemically relevant banks) and qualitative (nature of transactions) aspects of the present discussion are not included.
exception: In Germany uncovered short selling, in general,
is forbidden.

General problem for regulations: Regulations in single countries or regions are not effective, because banks immediately transfer businesses to unregulated regions. Global regulations are not achievable or are possible only after very long periods of negotiations. Reluctance to introduce effective regulations on order to avoid losses in the financial business. The following aspects are neglected in the Basel III concept but will be of significant importance for a future macro- and micro- prudential regulation framework:

(-) capital market oriented instruments ( contingent capital = liabilities which are converted into common capital in situations of shortages in required capital ratios) (-) structure of regulatory bodies ( Central Banks only or Central Banks and an independent institution(Germany)) (-) reducing the „systemic“ importance of large banks - universal banking or separate banking systems - interbank indebtedness (-) prohibition of special transactions (gambling)

Proposal for limiting banking transactions along the following criterion: Do transactions of banks contribute to economic welfare ? in detail: Do transactions of banks create, encourage or facilitate real and monetary transactions improving the welfare of the society ? problem: pure gambling: Capital gains of the winner are equal to the capital loss of the looser, the overall net value remains unchanged.

Example: Bank A issues a DJ- certificate to the public with the following (extremely simplified )characteristics: - the papers earns an interest rate of 0% if the DJ does not change more than +/- 2% - if the DJ goes up more than +2% the interest rate follows exactly - if the DJ looses more than 2 % the paper looses correspondingly Consequences: In all situations gains are matched by losses. In addition, both parties are confronted with additional risk. An overall increase in the net welfare of the society is not observable.

(4) Summary and Conclusions (-) The regulations of Basel III are a quantitave approach to make bank`s balance sheets more crisis proof. They will not be able to avoid future crises in a global system of banks using all financial instruments existing today. (-) Qualitative and structural regulations are necessary reducing the systemic relevance of large banks and limiting or prohibiting specific financial transactions.
