On the other hand, it would take much less effort to move one of the emerging market currencies – such as the Mexican Peso or South African Rand. To understand the relationship between market liquidity and volatility, you first need to understand what liquidity is. Pairs involving JPY, GBP, or emerging currency crosses usually show higher swings vs major pairs like EUR/USD.
For example, if there is a sudden change in interest rates, or if a country experiences political instability, the value of its currency may change dramatically. Traders who are able to anticipate these events and make trades accordingly can profit greatly, but those who are caught off-guard can suffer significant losses. Understanding forex volatility is crucial for traders because it helps them select the right pairs to trade, time entries and exits, and manage risk effectively.
For example, if a $1 asset moves 10c from its highest price point to its lowest price point in one day, its volatility would be 10%, because its price has moved a tenth of its overall value in one day. On the Bitcoin/USD price chart example below, showing a five-day period on an hourly chart, the price ranges from around USD $64,000 to volatile meaning in forex over USD $70,000 in a week. If you heed Warren Buffett’s word and look at market volatility as your friend rather than an enemy, there must be ways to make it work for you and your trading success. Whether it’s the US vs China, the US vs Europe, or any other region or country, trade wars can also spur volatility in the markets due to the billions or trillions of transactions involved. One way or another, the currencies involved in any trade war will be affected at some stage.
If that interest declines, the market pulls back toward the Dollar, causing abrupt changes in price. Volatility in USD/ZAR often becomes more extreme when global sentiment toward emerging markets changes without much warning. Traders adjust their positions rapidly if growth prospects alter, if commodity prices turn downward, or if policies in the region create uncertainty. Central banks impact interest rates, inflation rates, and monetary policies, which significantly affect currency pair values in the foreign exchange market. Following the high volatility of AUD/JPY, GBP/CAD stands as another currency pair with significant price swings.
All the inputs for the Black Scholes Pricing model are related to one another and therefore if you know the price of the option, you can back out the implied volatility of the forex option. So, if you see the price of an option (or the bid offer spread of an option), you can use an options pricing model to find the implied volatility of the currency pair. For risk, you can select how much you can handle, but volatility is out of your control. Keeping a trading journal to record your transactions is a highly recommended practise.
