Dubai: Saudi stock markets opened for foreigners officially on Monday, 15 June 2015, a move that could potentially change regional equity markets.

The $550 billion strong market became one of the last major economies of the world to open up for international investors.

The regulator says the major aim is increase institutional investments, even as market watchers expect capital flows to come in gradually.

The opening of Saudi markets is expected to boost the IPO and debt markets.

Global index provider S & P Down Jones Indices earlier said that it is in talks with eight mid-sized and small asset managers in Saudi to launch IPO indices.
