The table below shows the overall risk position of the Group at year-end 2004 and 2003 as measured by the economic capital calculated for credit, market, business and operational risk; it does not include liquidity risk.
| Economic capital usage in € m. | Dec 31, 2004 | Dec 31, 2003 |
| Credit risk | 5,971 | 7,363 |
| Market risk | 5,476 | 5,912 |
| Trading market risk | 1,581 | 972 |
| Nontrading market risk | 3,895 | 4,940 |
| Diversification benefit across credit and market risk | (870) | (1,152) |
| Sub-total credit and market risk | 10,577 | 12,123 |
| Business risk | 381 | 1,117 |
| Operational risk | 2,243 | 2,282 |
| Total economic capital usage | 13,201 | 15,522 |
To determine our overall (nonregulatory) risk position, we generally add the individual economic capital estimates for the various types of risk. When aggregating credit and market risk, however, we consider the diversification benefit across these risk types, which we estimate as € 870 million as of December 31, 2004 and € 1.2 billion as of December 31, 2003. The diversification benefit across all risk types has not yet been calculated.
On December 31, 2004 our economic capital usage totaled € 13.2 billion, which is € 2.3 billion or 15% below the € 15.5 billion economic capital usage as of December 31, 2003.
The reduction in credit risk economic capital primarily reflects the overall reduction in our lending-related credit exposures as well as the improved credit quality of our loan book. The reduction in total market risk economic capital is mainly caused by the decrease in nontrading market risk from alternative assets as well as lower risk from industrial holdings, which was partially offset by the increase in trading market risk economic capital. However, a substantial part of the increase in trading market risk economic capital is related to our refined stress testing parameterization introduced in 2004. Applying the previously implemented parameters to year-end 2004 data on a pro forma basis leads to a year-on-year increase in trading market risk economic capital of € 0.2 billion compared to the € 0.6 billion increase shown in the table. The reduction in business risk economic capital reflects an improved market outlook and our increasing ability to adjust costs in a market downturn.
The allocation of economic capital may change from time to time to reflect refinements in our risk measurement methodology.
