National Bank of Pakistan is the largest commercial bank operating in Pakistan . Its balance sheet size surpasses that of any of the other banks functioning locally. It has redefined its role and has moved from a public sector organisation into a modern commercial bank. The Bank's services are available to individuals, corporate entities and government. While it continues to act as trustee of public funds and as the agent to the State Bank of Pakistan (in places where SBP does not have a presence) it has diversified its business portfolio and is today a major lead player in the debt equity market, corporate investment banking, retail and consumer banking, agricultural financing, treasury services and is showing growing interest in promoting and developing the country's small and medium enterprises and at the same time fulfilling its social responsibilities, as a corporate citizen.
