State Bank of Pakistan Exchange Rates

The State Bank of Pakistan (SBP) publishes exchange rates for various currencies against the Pakistani Rupee (PKR) on a daily basis. They publish the exchange rates on the internet in PDF format at a deterministic URL for each day. This lib provides an interface to fetch and/or download the exchange rates for any given date.

Example Rate Sheets:

• 2025-08-27
• 2025-08-26
• 2025-08-25
• 2025-08-24
• 2025-08-23
• 2025-08-22

Note

These Exchange Rates are issued by the State Bank of Pakistan for Authorized Dealers to revalue their books daily on Mark-to-Market basis. M2M rate of USD is compiled as weighted average of closing interbank exchange rate collected through Brokerage Houses. M2M rates of other currencies are compiled on the basis of USD/PKR rate compiled from brokerage houses’ data and exchange rate of other currencies against USD quoted on Reuters Eikon Terminal.

Important

These rates will almost always differ from google rates (e.g. rates from google search).
