The currency of Pakistan is the Pakistani Rupee. The Pakistan Rupee was pegged against the British pound until 1982, when the Pakistani government adopted a managed float policy. This means that the exchange rate of the Pakistan Rupee is established through a free float.
However, the Pakistani central bank, the State Bank of Pakistan intervenes in the foreign exchange market to affect the value of the currency in order to meet particular macro-economic goals and reduce volatility of the exchange rate where possible.
Owning to the volatility and fragility of the Pakistan economy, the Pakistan rupee doesn’t have noticeably strong correlations with financials, commodities or other currencies.
