Standard Chartered has set aside $900m to cover fines resulting from regulatory investigations in the US and Britain, potentially drawing a line under probes which have dogged the bank for years.
News of the provision, made for the fourth quarter of last year, comes ahead of a strategy update from the bank along with its 2018 earnings results next week,.
The bank's chief executive Bill Winters is widely expected to outline an overhaul of operations.
In a filing to the Hong Kong Stock Exchange today, StanChart said the provision related to the potential resolution of US investigations into alleged violations of US sanctions, and for probes relating to foreign exchange trading.
The filing is the first time the bank has quantified the possible cost of the investigations.
Previously it said only in filings that it was "not practicable" to estimate the financial impact because the range of potential outcomes was too broad.
StanChart also included in the provision a £102.2m fine from Britain's Financial Conduct Authority related to historical financial crime controls. It said it was considering its options in relation to the penalty.
The UK regulator declined to comment when contacted by Reuters.
StanChart has been the subject of multiple investigations by US authorities into its dealings with Iran, which is the subject of heavy US sanctions.
In 2012, the bank agreed to pay $667m to settle alleged sanctions breaches from 2001 to 2007.
It also agreed deferred prosecution agreements with the Department of Justice and New York County District Attorney's Office. The agreements were extended to March 31 this year in December 2018.
The current investigations are examining the extent to which the bank allowed clients with Iranian interests to conduct transactions after 2007, as well as the extent to which it shared such dealings with authorities at the time of the 2012 settlement.
In October, Winters said US authorities were also investigating whether StanChart breached Iran-related compliance rules as recently as 2013.
Media reports last year said London-based StanChart faced a possible $1.5 billion fine for Iran-related sanctions violations.
The 2018 provision will reduce profit at the bank, which analyst estimates had previously put at $3.9 billion, Refinitiv data showed.
Last month, New York's financial watchdog fined StanChart $40m for attempting to rig foreign exchange transactions from 2007 to 2013 - a penalty which the bank said was also included in the $900m provision.
Asia, Africa and Middle-East focused StanChart has seen a slump in fortunes over the past few years as restructuring under Winters repaired a balance sheet hit by excessive lending in the previous decade, but left the bank struggling to lift profit.
StanChart has projected revenue growth of 5-7% over the next three years, but analysts said a consensus of estimates was "anchored at the lower end" of the guidance, adding that even this "looked challenging".
