His personal life was also flourishing. Mr. Adoboli, until about four months ago, lived in a stylish building adjacent to London’s famous Brick Lane, a bustling thoroughfare known for its nightlife and curry houses.

Regulators have been toiling away to write the specific provisions of the Volcker Rule, which is intended to prevent banks from trading for their own account and is named after Paul A. Volcker, the former chairman of the Federal Reserve.
