If the exchange rate for Papua New Guinean kina (PNG kina) changes from 32 to 43 Japanese yen, this indicates that the value of the PNG kina has decreased relative to the Japanese yen.
In terms of currency exchange rates, when the number of yen required to purchase one kina increases (from 32 yen to 43 yen), it means that it now takes more yen to buy one kina. This scenario suggests that the PNG kina is weakening against the Japanese yen, making the kina less valuable in terms of yen.
Therefore, in conclusion, the PNG kina is depreciating relative to the Japanese yen as the exchange rate increases.
