Market capitalization of the Indonesia Stock Exchange (IDX) has surpassed its psychological boundary of IDR 5,000 trillion (USD $512.82 billion) last week, supported by the new record high level position of the Indonesia Stock Index (IHSG) on Friday at 5,145.68 points. Up to 17 May 2013, the IHSG gained 18.41 percent this year, thus outperforming all other major stock indices in Asia except for the Philippines and Japan's Nikkei, which gained 41.64 percent this year amid an aggressive stimulus plan of the central bank of Japan.
Apart from robust demand for Indonesian stocks in recent years, the large increase in market capitalization of Indonesia's stock exchange is also due to many initial public offerings (IPOs) and rights issues (currently 464 companies are listed on Indonesia's stock exchange). This growth is yet another indicator of strong expansion of Indonesia's economy. The value of the IHSG's market capitalization is currently equivalent to about 45% of Indonesia's gross domestic product. This figure means that there is still ample room for growth as regional economies have figures that surpass 100 percent, such as Singapore and Malaysia which are at 194 percent and 137 percent of GDP respectively. Market capitalization of Singapore's stock exchange is currently about USD $605.1 billion. By 2018 Indonesia hopes to surpass this level.
