JAKARTA: Indonesia's annual economic growth in the second quarter came in at its slowest in three as household and public spending eased, official data showed on Wednesday (Aug 5), though the figure was better than expected. Investment growth accelerated at the fastest pace in a year to stand at 6.87 per cent in the second quarter. In terms of industries, manufacturing growth slowed, while the mining sector contracted due to quota curbs. "We believe both the government and Bank Indonesia will need to strike a delicate balance between supporting growth and maintaining macroeconomic stability," said Bank Permata economist Faisal Rachman. "These risks are likely to constrain the economy's ability to sustain stronger growth momentum going forward," he added.
