Indonesia’s central bank is showing its willingness to sacrifice economic growth for currency stability in its latest aggressive move on interest rates, Bloomberg reports. Bank Indonesia (BI) surprised economists with a bigger-than-forecast 50 basis-point hike on Friday, aimed at halting a currency rout. Bank Indonesia has taken various measures to try to boost rupiah use and it is once again prodding firms to sell dollars, but companies surveyed by Reuters are maintaining US currency holdings and only meeting minimum hedging requirements. Bank Indonesia’s outlook for 2018 GDP growth remained 5.1-5.5 per cent, which took into account the rate hikes and looser mortgage rules, The Business Times reports, quoting assistant to BI governor Filianingsih Hendarta. Growth in 2017 was 5.07 per cent.
