An industry-wide slump in revenue from bond trading is expected to help push down Deutsche Bank's pretax profit by 44 percent in the first quarter, adding fuel to talk Germany's largest lender will need to raise equity capital.
Deutsche Bank is expected to post quarterly pretax profit of 1.4 billion euros ($1.9 billion) on Tuesday, around 1 billion less than a year earlier, the average forecast in a Reuters poll of banks and brokerages showed on Friday.
Declines in the business - traditionally the main money spinner at Deutsche Bank - are seen hampering the lender's bid to build up its capital cushion to meet tough new banking rules introduced in the wake of the financial crisis.
"Deutsche Bank is rather weakly capitalized, and there is a weak trend in fixed income and in investment banking, so that you can't get much from retained earnings," said a German shareholder, whose company policy does not authorize him to speak publicly.
Deutsche Bank managed to boost its core tier one ratio - a closely watched measure of balance sheet strength - to 9.7 percent at the end of 2013, but a raft of new banking rules are likely to bring the ratio closer to 9 percent by next year and the lender still faces litigation costs around the world as fallout from the financial crisis, the investor said.
"A capital ratio of around 9 percent is simply too low for an investment bank like Deutsche Bank," the investor said.
Worries about the capital cushion and dimming revenue prospects have led to repeated speculation that Deutsche Bank would need to raise equity capital before long.
Financial daily Handelsblatt on Friday reported the lender was considering a capital increase of up to 5 billion euros this year to cope with new regulations and European "stress tests" of the industry, sending its shares down more than 2 percent.
The paper cited sources at the bank as saying that no decision had been made but that Deutsche Bank's co-chief executives, Juergen Fitschen and Anshu Jain, were thinking of a "Plan B" to give an extra fillip to its efforts to close the gap with international rivals in terms of capital strength.
Deutsche Bank declined to comment on the report.
Jain told Reuters earlier this year that his bank had not discussed raising equity capital, though it was going ahead with plans to bolster other forms of regulatory capital.
Germany earlier this month gave its banks long-awaited legal certainty on the tax treatment of "CoCo" bonds that can be converted into shares to bolster their capital, and Deutsche Bank is expected issue this type of bond soon.
In light of Deutsche Bank's efforts to boost regulatory capital by other means, investors said they did not expect an equity capital hike in the near term.
"But it's always a question of the lesser evil," said Assenagon fund manager Michel Huenseler. "On the one hand, the last capital increase was very well received, but on the other, Jain seems to have categorically excluded it."
Last year, Deutsche Bank raised 2.96 billion euros by selling 90 million shares.
Some analysts said an equity capital increase would put an end to the uncertainty, which has dragged on the shares.
"We would welcome a capital increase with a volume of at least 5 billion euros as it would end concerns about Deutsche Bank's capital level and would put the bank in a position to win market share again instead of shrinking its balance sheet to improve capital ratios," said Equinet Bank's Philipp Haessler.
