Lately i been confused with the fact, when should one do a currency change. Here is a scenario,i am living as a expat in Uk, and i need to take out money from my international account from a another currency. The Uk currency show 155 day rate. Whereas by evening it became 145. IMO, if i do a change on 155, it would benefit me, but someone told me when the rate is less e.g 145. It would be more beneficial. TBH i don't understand how the maths work in this.?
If you are exchanging your foreign currency (US$) into GBP, then it will be better for you at 145 since you are paying less for each pound.
If you are changing your GBP into foreign currency, then it will be worse for you at 145 since you are receiving less for your pounds.
With PKR the rate you are quoting is PKR per pound, so you would divide by 145. Thus 10,000 PRK divided by 145 would give you about 69 pounds.
Using a rate of 155 you would receive PKR 10,000/155 = 64.5 pounds.
As you can see, you are better off at the 145 rate.
