However, the inter-bank has to open trading after few hours. This seems to be a Google and Yahoo Exchange System glitch only for the PKR currency.
Moreover, Yahoo Exchange System corrected the value after the short interval. But as highlighted you can see a major drop in the image. Still Google system has to update the correct price of USD to PKR.
For the all the traders, we have seen there was not any drop in USD to PKR conversion. This was just due to small glitch will be resolved soon. According to XE USD to PKR is still trading at the value of 178.51282 PKR against 1 USD.
