Companion App FC point price increase?

Is there a reason why the price of FC points on the companion app suddenly increased by like nearly $30??

I live in Korea, but just up till last week, the price of 12000 fc points was 110,000 Won, which is roughly 99 dollars.

But today, it was 149,000 won, which is like 129 dollars. why?? It's more expensive than the in-game purchase all of a sudden.
