KARACHI – The State Bank of Pakistan (SBP) has once again advised the general public to exchange the phased out and larger sized banknote of Rs 500 denomination at the latest by September 30. According to an issued press release, the notes can be exchanged at the field offices of SBP Banking Services Corporation and the branches of all commercial banks throughout the country.
