Margin requirements for Forex currency pairs can vary depending on the broker and the currency pair being traded. Generally, the margin requirements for major currency pairs such as EUR/USD, USD/JPY, and GBP/USD tend to be lower compared to the margin requirements for exotic currency pairs such as USD/HKD, USD/CNH, and USD/TRY.

For example, a broker may require a margin of 2% for a major currency pair such as EUR/USD, meaning that the trader would need to deposit $2,000 to open a position worth $100,000. However, the same broker may require a margin of 5% for an exotic currency pair such as USD/HKD, meaning that the trader would need to deposit $5,000 to open a position worth $100,000.

It's important for traders to check with their broker for the specific margin requirements for the currency pairs they plan to trade, as these requirements can vary and can have a significant impact on their trading strategies and risk management.
