US Dollar in Pakistan is getting more and more stronger with each passing day. Normally, when US Dollar gets stronger, then other currencies like British Pound, Euro etc gets weaker: and $ also affect other currencies including Pak Rupee.
But if we take a look at the current Pak-Rupee vs $ vs other-currencies comparison, we will see that $ is not getting as stronger against other currencies as it is getting against Pak-Rupee.
Then what is the reason for Rs to get weaker against $?
There are many factors that influence the stability of a currency. Currently [according to experts], the demand for $ is getting high in Pakistan. Some experts believe that buying of $ by different banks [Pakistani Banks] is the main reason why Rs is under pressure. Some say that $ reserves have gone down and just like this, other experts give more reasons for the current scenario.
One other interesting thing to note is the rate of Pak Rupee against $ in the inter-bank. The selling rate is currently at around Rs. 85.20. This rate is much less than what it was few days ago: but at that time, rate of $ was not very high in the open market.
Today, rate of $ against Rs is approximately Rs. 87.00 [selling rate]. This rate can be different at different currency exchangers and in different cities. In some places, people have reported a rate of Rs. 87.50.
I have never seen $ at such a high rate in the open market in my life. Increasing $ rate means expensive petroleum products which will result in an increase of almost everything [fares, food products, clothing etc].
