Does any one have a good logical way to always get these problems right? I’m having issues thinking through when to use the bid or offer.
Example 1:
Do you have a better way to think abou this?
Example 1:
- At origination, you sold $6M AUD to be deliver against the GBP @ 1.0256 (AUD/GBP). They ask you how to Mark-to-market with 1 month remaining? They give you the bid-offer 1.0468 - 1.0470.
- My logic here is: if I want to cancel the contract, I need to buy AUD (which is equivalent to selling GBP).
- Since the rate is already in AUD, then you buy at the bid!
- You purchase $20M GBP for deliverly against USD @ 1.0078 (USD/GBP)
- They give you the Bid-offer spot rate 1.0102 - 1.035
- My logic: to MTM or cancel the contract you will need to sell $20M GBP (selling the base). This is equivalent to buying dollars.
- Trick: thinking that I need to buy dollars at the offer rate (highest rate) is wrong. I think it is because the base is the currency being quoted. So buying USD is = to selling GBP (which is the original fx trade per say). so you would use the BID???
