KARACHI - The current wave of senseless killings and barbarism in Karachi, the economic and commercial hub of the country, has dealt a severe below to the national economy to the tune of billion of rupees. Due to one-day strike in the city, the national economy suffered the loss of Rs10 billion. While the unchecked violence spreading over a number of weeks caused total loss of Rs100 billion to the national economy, economist, industrialist and traders have estimated. Besides, the domestic investors are reluctant to invest in the country and the foreign investors follow the suit. Due to uncertainty and day-to-day strikes in the city, the foreign importers also feel that they should give repeat orders for imports from Pakistan thereby affecting exports of the country. Whenever there was strike in Karachi, the overseas Pakistanis who wanted to send remittances to their families through banking system switched to hundi system, said economist Dr Shahid Hassan Siddiqui, adding the strikes could therefore affect the quantum of remittances and there was pressure on the rupee-dollars parity. Breakdown of the law and order hampered production in about 10,000 big and small industrial units located in five industrials areas of the city as activities in majority of the industrial areas came to a grinding halt. All markets and shopping centres remained completely shutdown affecting business of dealers, wholesalers of interior parts of Sindh and the upcountry. Nisar Shaikhani, a leading industrialist and former Karachi SITE Chairman, said one day closure in the SITE only caused about Rs300 million to 400 million losses on account of export. Besides, it would also affect 0.5 million direct employees, he added. The total loss including exports has reached around Rs 1 billion per day to one industrial zone out of the five industrial zones in Karachi. Shamim Ahmed Shamsi, former Karachi Chamber of Commerce and Industry president said the city had suffered Rs10 billion single-day loss in terms of production, suspension in sales and exports, demurrage at ports on imported goods, loss of perishable goods, daily wage earners, non-salary disbursement, transportation of goods, non-plying of public transport, sale loss to shop owners and government revenues. There were many invisible losses as well, he added. The leaders of the Karachi Traders Association claimed that businessmen had suffered a loss of around Rs40 billion in current wave of violence in the metropolis due to closure of 0.65 milion shops located in 580 markets, 84 shopping centres, 96 superstores and 227 bazaars which employed 0.85 million workers.
