The prosecutor has accused Bonnesen of concealing information relating to the bank's work against money laundering in the Baltics during his time as CEO.
Information that came to light in internal investigations was withheld from shareholders and authorities, the prosecutor has stated.
The charge relates to gross fraud or gross market manipulation.
In addition, she is accused of insider trading.
Throughout the investigation and subsequent trial, Bonnesen has maintained his innocence.
She believes that she has not done anything criminal.
The prosecutor has singled out SVT's Uppdrag gränskning program as decisive for the information to come to light.
Bonnesen and her defenders say for their part that the program spread an "incorrect image".
