Indonesia has become the biggest and the most valuable emerging market in Southeast Asia, overtaking both Malaysia and Thailand.

This week, the total value of the companies that traded in Indonesia reached $416 billion. Early in 2013, Indonesia's market capitalization had overtaken that of Malaysia and Thailand but was soon replaced by Malaysia.

In the past three years, Malaysia was leading at the top, while Thailand also held the top slot for a short span of time. But the huge stock of net oil paved the way for Indonesia, Asia's only net oil exporting nation, to be at the peak.

As Indonesia is rapidly showing signs of advanced economic development, the country is mentioned as a suitable candidate to be included in the BRIC countries (Brazil, Russia, India and China).
