Hi, I will try and keep this short and simple. I'm moving to the USA soon from the UK. GBP has taken such a hammering over brexit that it has already made it a lot harder. I would like to leverage some of my savings in order to hedge against further devaluation of GBP against USD. Can anyone please give me an idea of the best way to do this please? Im bearish sterling and cant see much hope for upside so I'm guessing I should be shorting it but I am unsure of the position sizing in percentage terms in order to achieve a hedge. Not looking to profit, just trying to protect my savings so they are still useful when I come to move. Thank you for any help you can give.
Welcome to the forum, MC
Since your goal simply to hedge the value of your savings, not to profit from speculation, then you position sizing should be determined by the amount you have saved. For example, if you have £1 million then you can short 1 million GBP/USD. The way this position size is displayed will vary from one platform to the next but the concept is still the same.
On our Trading Station for example, this trade size would be displayed as 1,000K of GBP/USD (where K stands for 1000 currency units). On MT4, this would be displayed at 10.00 of GBP/USD in volume where 1.00 is one standard lot of 100,000 currency units. Regardless of the platform you choose, when you short 1 million GBP/USD, then you will make $100 each time the exchange rate drops by 1 pip, and you will lose $100 each time the rate rises by 1 pip.
Here's an example based on the current GBP/USD exchange rate of 1.3133:
You short 1 million GBP/USD at this rate. That means, you've effectively sold 1,000,000 British Pounds for which you've received 1,313,300 US Dollars. Suppose that by the time you move to the US, the GBP/USD exchange rate has dropped to 1.2500. At this time, you decide to close out your short 1 million GBP/USD position, since you've already transferred your savings to the US. To close or cover this short, you must buy back the 1 million GBP a the current rate, which costs you $1,250,000. Since you originally received $1,313,300 your hedge made $63,300 or $100 for every pip the exchange rate dropped. This will offset the loss in your GBP savings which you were hedging.
