Between April and June, the economy grew by 6.4% from a year earlier. Analysts had expected growth of 6.1%.
Economists said low interest rates, stable consumer price growth and strong consumer and business confidence had helped boost domestic demand.
Indonesia is South East Asia’s largest economy.
“As per today’s data, Indonesia remains one of the fastest growing, and perhaps more importantly, one of the most stable economies in Asia,” said Taimur Baig, an economist with Deutsche Bank.
Domestic consumption accounts for almost 60% of Indonesia’s overall economy.
Despite the robust numbers and its relatively low reliance on exports, analysts warned that Indonesia’s growth may be still be affected by a slowdown in the global economy, especially in China.
Commodities and natural resources make up the bulk of Indonesia’s exports and China is a key market for shipments of those products.
However, growth in China has been slowing. The Chinese economy grew by 7.6% in the second quarter, its slowest pace of growth in three years.
As a result, demand for commodities is expected to slow, resulting in a fall in prices, which may hurt Indonesia’s growth.
