Illustration: Indonesia tightens stock market oversight to avoid MSCI downgrade

Indonesia has announced a new package of measures to combat stock market manipulation, seeking to head off a threatened downgrade of its investment status by global index provider MSCI.

At a press conference yesterday, Indonesia Stock Exchange (IDX) chief Jeffrey Hendrik said the exchange would expand a committee that will draw up a list of stocks with high shareholder concentration to include independent parties, according to Reuters. Possible additions include Indonesian academics and F. Taylor Chapman, an American businessman on the board of state investment fund Danantara, who would represent foreign investors. The IDX also plans to launch investigations when it detects possible coordinated trading aimed at manipulating share prices, and to freeze suspicious investor accounts.

Hasan Fawzi, capital market supervisor at the financial regulator, encouraged the IDX "to strengthen the mechanism and methodology of trading supervision, including its capacity to identify patterns of irregular transactions, detect coordinated trading and strengthen the mechanism to respond to such events."

The measures follow MSCI's October 16 announcement that it had launched "a consultation on a proposal to reclassify the MSCI Indonesia Indexes from Emerging Market to Standalone Market status." That announcement sent the Indonesian market down 15 percent over two days of trading. President Prabowo Subianto last week accused MSCI of trying to "intimidate" Indonesia.

MSCI had earlier threatened a downgrade to frontier market status in January, citing coordinated share purchases, high ownership concentration and limited free float. Indonesia responded by doubling the minimum free float for listed companies to 15 percent, and top exchange and regulator executives stepped down. But MSCI said in October that "significant concerns remain around market dysfunction, including continued suspected coordinated trading behavior and lack of evidence of meaningful enforcement," and that reclassification to Frontier Markets "would not properly recognize the depth of the market problems."

The IDX will exclude stocks with high shareholding concentrations from its main Jakarta index starting November 2. Whether the package is enough will be known when MSCI makes its determination next June. As Larry Luckey wrote in The Diplomat last week, the reforms are sensible, "but announcing new regulations and actually enforcing them are two different things."

Analysis

Why This Matters

MSCI is a primary benchmark for institutional investors, and a downgrade could potentially trigger billions of dollars in capital outflows from Indonesian stocks.
The November 2 exclusion of high-concentration stocks changes which companies sit in the main Jakarta index, affecting their visibility to foreign investors.
The June decision will test whether announced rules translate into enforcement.

Background

MSCI has pressed Indonesia on market transparency since January, when it threatened to reclassify the country to frontier market status over coordinated share purchases, high ownership concentration and limited free float. Indonesia responded with a reform package that included raising the minimum free float for listed companies to 15 percent, and leadership changes at the exchange and regulator. MSCI's October 16 announcement said those reforms had not gone far enough, citing suspected coordinated trading and little evidence of enforcement.

Key Perspectives

MSCI: says significant concerns remain about market dysfunction, including suspected coordinated trading and lack of meaningful enforcement, and has proposed reclassifying Indonesia's indexes to Standalone Market status. President Prabowo Subianto: has accused MSCI of trying to "intimidate" Indonesia. Hasan Fawzi: the capital market supervisor at the financial regulator, wants the IDX to strengthen its supervision mechanisms and its capacity to detect coordinated trading and respond. Larry Luckey: writing in The Diplomat, called the proposed reforms sensible but said announcing regulations and enforcing them are two different things.

What to Watch

MSCI's final determination, expected next June, on whether Indonesia stays in Emerging Market status.
Whether the IDX's expanded committee and new investigation powers lead to visible enforcement actions before then.
Market reaction to the removal of high-concentration stocks from the main Jakarta index from November 2.
