In my opinion, this move is to end a weakening trend of Rupiah that started in early 2020. To do that, Rupiah must continue to move below Rp14,700/USD.
If somehow Rupiah stays within Rp15,000/USD range, there is a possibility that a weakening trend of Rupiah will still happen anytime soon. This time, Rupiah can shoot up to Rp17,000 - Rp18,000/USD.
I am hoping to see a further strengthening of Rupiah in the next 2-3 weeks to reach a level below Rp14,700/USD.
