Deutsche Bank is cutting 15,000 global jobs and shedding assets in which some 20,000 staff are employed.
The cuts come as new chief executive John Cryan starts to implement a deep overhaul aiming to improve returns at Germany's biggest bank.
John Cryan said the bank will sacrifice its 2015 and 2016 dividends as it seeks to bolster its finances and retain money to pay for sins of the past.
"I do not think that 2016 and 2017 will be strong years," he said today.
Cryan is under pressure to overhaul Germany's biggest bank, with costly litigation from past scandals and fallout from a market rout in Asia pushing its valuation well below rivals.
The bank said it would close branches in Germany, and will also shut businesses in Malta, Argentina, Chile, Mexico, Finland, Peru, Uruguay, Denmark, Norway and New Zealand.
"Deutsche Bank does not have a strategy problem. We know exactly where we want to go. But we have had a grave problem in implementing it," Cryan said, addressing reporters in German.
This was in contrast to his predecessor Anshu Jain who regularly drew criticism for never mastering the language.
Cryan said staff will feel the pain.
"I have said that it would not be all sweetness and light," he said, adding it would be unacceptable not to share some of the cost of the settlement of interest-rate rigging and consequences of poor past behaviour.
In the context of the group making a 2015 loss, its supervisory board will discuss if it will be appropriate for the board to pay bonuses, he said.
Co-CEO Juergen Fitschen acknowledged the bank has not yet done enough in changing its behavioural culture.
"Cultural change ... it needs to be filled with content. What we have brought about is only the beginning," Fitschen said.
The lender is to axe 9,000 full-time jobs and 6,000 external contractor positions. Three quarters of the other 20,000 jobs to go are at retail unit Postbank, which Deutsche Bank is spinning off.
"We were concerned that our shareholders thought cost-cut goals were not ambitious enough. We think they are realistic based on the need to remain competitive," Cryan said.
"We think we should retain capital in order to strengthen the company. Because we have to run business on the basis that we could encounter stress. We need to build a buffer above the minimum."
Deutsche Bank said late last night that it was targeting a reduction of its risk-weighted assets to about €320 billion by the end of 2018 from €416 billion at the end of June, towards the top end of analysts' expectations.
"The plan is based on the elimination of the Deutsche Bank common share dividend for the fiscal years 2015 and 2016," it said in a statement, adding it aimed to resume paying dividends thereafter.
Ever since its post-World War Two re-establishment in 1952, Deutsche Bank has always paid a dividend.
Earlier this month, the lender announced it would split its investment bank in two and part ways with three of its eight management board members.
The bank also said it was aiming to bring down adjusted non-interest expenses to less than €22 billion by 2018 from €23.8 billion in 2014, and to reduce its cost/income ratio to 70% in 2018 from 84.3% at the end of June.
By comparison, Barclays, Credit Suisse and UBS, which are also cutting costs and devising new strategies, currently only spend 64 to 77 cents to earn a euro.
Other major international banks such JP Morgan and UBS made swifter changes to address persistently low interest rates and tighter regulation after the financial crisis.
While Credit Suisse, which also intends to slim down its investment bank, plans to raise 6 billion Swiss francs from investors to bolster capital, Deutsche Bank has not so far signalled it is considering such a step.
Deutsche Bank also posted a 20% rise in revenue at its lucrative bond trading business in the third quarter, helping take the sting out of a record €6 billion group pretax loss.
Revenue at its Corporate Banking and Securities business rose 2% to €3.2 billion, helped by higher revenue in rates, credit and distressed and emerging markets.
Peers such as Morgan Stanley and Goldman Sachs reported steep declines in bond trading performance in the quarter.
The loss was caused by massive charges for goodwill and legal expenses at its investment bank and on assets earmarked for disposal, as well as higher litigation charges.
