Deutsche Bank this morning moved to put an end to speculation that it will need to raise additional capital, confirming it expects to report a profitable second quarter at the end of the month, after bank stocks have come under further pressure in recent weeks on concerns the balance sheet repair cycle is not yet over.

The bank also said it expects its tier one ratio, a regulatory measure of its financial strength, to remain around 9%. It said: "Therefore the bank does not expect its financial performance in the second quarter to result in a requirement for further capital." At the end of the first quarter tier one capital was 9.2%.
