Saudi Arabia is increasingly looking to just float oil giant Saudi Aramco locally as plans for an initial public offering on an international exchange hang in the balance, sources close to the process say.

DUBAI/LONDON, March 13 (Reuters) - Saudi Arabia is increasingly looking to just float oil giant Saudi Aramco locally as plans for an initial public offering (IPO) on an international exchange such as London or New York hang in the balance, sources close to the process said.

The kingdom is counting on being awarded emerging market status by index complier MSCI in June to help Saudi Aramco attract Western funds, in addition to cornerstone investors from China, Japan and South Korea, the sources said.

"I would guess it is about evens that there will be no international IPO," said a high-level source familiar with the preparations, saying they were proving to be a disappointment.

Saudi Arabia is planning to list up to 5 percent of Saudi Aramco in an initial public offering that could value it at up to $2 trillion and make it the world's biggest oil company by market capitalisation.

Saudi Energy Minister Khalid al-Falih said last week that Aramco was too important to risk listing in the United States because of litigation concerns, such as existing lawsuits against rival oil companies for their role in climate change.

British officials have been told by Saudi counterparts London has a chance to secure the listing but only in 2019 at the earliest, according to the Financial Times, and sources told Reuters the kingdom was now focusing on a listing on the local exchange, or Tadawul.

"The only thing we know today is that Tadawul will be the key listing location as our national exchange," Falih told CNN.

"We are waiting for the reforms to be in place and to join MSCI and Aramco listing in Tadawul will be catalytic for that capital market as we bring international capital to the kingdom," he told the U.S. channel last week.

MSCI Flows

The initial public offering is the centrepiece of Crown Prince Mohammed bin Salman's plan to diversify the Saudi economy beyond oil and it would also boost the kingdom's budget which has been hit by low oil prices.

Initially planned for 2018, preparations have been hit by rows over whether Aramco should list on major Western markets at all. An advisory council to the government asked the securities regulator this year to study the impact of a local listing amid concern a huge IPO could harm the market.

MSCI has proposed giving its existing Saudi Arabia stock index emerging market status rather than standalone status following a series of market reforms by the kingdom such as raising caps on foreign ownership of companies.

MSCI will give its decision in June and, if positive, the reclassification would be in two steps in May and August 2019.

According to an update of the MSCI proposal published in February, Saudi Arabia would have a market capitalisation of $124 billion in MSCI's Emerging Markets Index, giving it an index weight of 2.3 percent, on a par with Thailand.

Based on the assumption that another $100 billion would be added through an Aramco initial public offering, the kingdom's weighting would rise to about 4 percent, which would be bigger than Russia's weighting of 3.4 percent, for example.
