The US lender, which is working towards a full banking licence in Saudi Arabia, ended a five-decade presence in the kingdom in 2004 but in 2015 won permission to invest directly in the local stock market and last year gained approval to begin investment banking operations.

"I can see real interest awareness and potential demand for Saudi exposure," Azevedo told Reuters on the sidelines of a conference in Abu Dhabi.

He said a number of companies in Saudi Arabia were working on initial public offerings and that he was optimistic on the level of demand for Saudi stocks.

Foreign investors dumped Saudi equities at the end of last year amid worries over the blow to Saudi Arabia's relations with the West following the murder of journalist Jamal Khashoggi - a critic of the Saudi leadership - in Istanbul on Oct. 2.

But demand for Saudi securities has picked up this year, ahead of the kingdom's inclusion in the emerging-market indexes of MSCI and FTSE Russell later this year. Last month foreigners bought a net 4.36 billion Saudi riyal ($1.2 billion) of Saudi stocks, according to stock exchange data.

The Saudi index is up nearly 9.5 percent this year.

Azevedo said market sentiment towards Saudi Arabia was "neutral to positive."

The inclusion in the indexes is expected to attract $15 billion of benchmark-linked funds and billions more in active funds.

Citi expects business in the region to come from the chemical sector, as well as real estate, retail, diversified industrial companies, and banking, said Azevedo.
