Yes USD only, to accumulate 10000 points need to purchase 5000+5000(💯 Bonus) @ $67.5 which is equals to ₹5703.68, usually forex charges will be 3.5%(using axis atlas card) on top of the transaction amount.so 5703.68%3.5 will be ₹199.62.
So total transaction amount will be ₹5703.68 + ₹199.62 =₹5903.3 to get 10000 IHG points.
So, 5903.3/10000= ₹0.59/point
Hope calculation gives a better understanding here. Let me know any questions regarding this.
Thank you
