(The Wall Street Journal) LONDON -- One of Deutsche Bank's proprietary trading desks will abandon certain types of trades and reassign some staff after losing around €100m, or about $135m, in the credit markets over the past month, according to a person close to the bank and familiar with the unit.

The amount is relatively small for Deutsche Bank, which earned €3bn for the first six months of this year. But it is another sign of how jitters over US sub-prime mortgages that have infected the broader credit markets are affecting banks and investors.
