Gold price rose due to price rise in international market as well as continuous exchange rate fluctuations in local market - investors are buying gold to hedge it against any abnormal loss due to exchange rate differences, thus supply and demand has made its price to rise up.
As I earlier wrote, it's good only for a short period. Who will not want to earn profit at risk free rate of 12.25% per annum or 3.0625% per quater? You have to note that the investors (foreigners) will want their returns in dollars, and how will you pay them at maturity when you are already short of dollars?
Furthermore, it will force local investors to put their savings in banks rather than used them to expand their businesses nor they will be able to borrow loans at such high interest rates of 11.89% (SBP interbank rate) in already critical financial condition.
