Steps for Islamization of banking and financial system of Pakistan were started in 1977-78. Pakistan was among the three countries in the world that had been trying to implement interest free banking at comprehensive/national level. But as it was a mammoth task, the switchover plan was implemented in phases. The Islamization measures included the elimination of interest from the operations of specialized financial institutions including HBFC, ICP and NIT in July 1979 and that of the commercial banks during January 1981 to June 1985. The legal framework of Pakistan’s financial and corporate system was amended on June 26, 1980 to permit issuance of a new interest-free instrument of corporate financing named Participation Term Certificate (PTC). An Ordinance was promulgated to allow the establishment of Mudaraba companies and floatation of Mudaraba certificates for raising risk based capital. Amendments were also made in the Banking Companies Ordinance, 1962 (The BCO, 1962) and related laws to include provision of bank finance through PLS, mark-up in prices, leasing and hire purchase.
Separate Interest-free counters started operating in all the nationalized commercial banks, and one foreign bank (Bank of Oman) on January 1, 1981 to mobilize deposits on profit and loss sharing basis. Regarding investment of these funds, bankers were instructed to provide financial accommodation for Government commodity operations on the basis of sale on deferred payment with a mark-up on purchase price. Export bills were to be accommodated on exchange rate differential basis. In March, 1981 financing of import and inland bills and that of the then Rice Export Corporation of Pakistan, Cotton Export Corporation and the Trading Corporation of Pakistan were shifted to mark-up basis. Simultaneously, necessary amendments were made in the related laws permitting the State Bank to provide finance against Participation Term Certificates and also extend advances against promissory notes supported by PTCs and Mudaraba Certificates. From July 1, 1982 banks were allowed to provide finance for meeting the working capital needs of trade and industry on a selective basis under the technique of Musharaka.
As from April 1, 1985 all finances to all entities including individuals began to be made in one of the specified interest-free modes. From July 1, 1985, all commercial banking in Pak Rupees was made interestfree. From that date, no bank in Pakistan was allowed to accept any interest-bearing deposits and all existing deposits in a bank were treated to be on the basis of profit and loss sharing. Deposits in current accounts continued to be accepted but no interest or share in profit or loss was allowed to these accounts. However, foreign currency deposits in Pakistan and on-lending of foreign loans continued as before.
