What is a rupiah you might ask. Rupiah is the national currency of Indonesia, aka IDR (Indonesian Rupiah). $1 USD = 13.295 IDR (at the time of this writing). To check the rate, open Google and type USD to IDR and you will have the current exchange rate. When I first moved to Bali in 2012, the exchange rate was $1 USD = 9.800 IDR. That is better than 35% increase in buying power. Some might want to call that inflation, but if you use a bottle of beer as the standard, there has been no change.
