HBL (Habib Bank Limited) is primarily owned by the Aga Khan Fund for Economic Development (AKFED).
While historically, the Habib family played a significant role in the bank's founding, AKFED is currently the major shareholder and controlling entity. HBL is a publicly listed company, meaning shares are also held by various institutional and individual investors.
Therefore, while the answer to the original question could be interpreted in terms of historical roots, the current owner, in a practical, controlling sense, is AKFED.
