Manas Kapoor, who worked as a product controller at Morgan Stanley, became addicted to gambling and feared he would be sacked after an accounting error cost the bank millions of pounds.
The 35-year-old killed his wife Shivani, also 35, in a fit of rage on the day he was due to face a disciplinary hearing.
The couple, originally from Delhi, had moved to the UK after their marriage. Shivani was working as a paediatric occupational therapist here.
"Our thoughts are with Shivani's family and her 18-month-old child, who have lost a loving daughter and mother," he added.

A postmortem examination gave the cause of death as manual compression of the neck.
Further injuries were discovered on Shivani's body during the postmortem examination, included bruising on her back, elbows and shoulders, consistent with being pinned against a wall or floor, deep bruising around her nose suggesting a hand had been put over her face, and her neck had been compressed so hard it had bruised her spine.
Kapoor was arrested at the scene but denied murder.
Kapoor admitted he was 8,000 pounds in debt and had been borrowing from friends and family to cover his losses, the court heard.
Shivani's family has since been fighting for the custody of her daughter Vania from her paternal grandparents who wanted to move her to Glasgow.
