BENGALURU, June 16 (Reuters) - The UAE stock markets outperformed other Gulf markets on Tuesday as trading resumed after the Islamic New Year holiday, in their first opportunity to assess the preliminary peace agreement reached two days earlier between the United States and Iran.

US President Donald Trump said on Monday that the two countries had signed an initial agreement, but details have not yet been released. Both sides have said that a permanent agreement requires further negotiations.

A senior Iranian official said yesterday that Tehran would freeze its nuclear activities until a final agreement is reached, and would refrain from any new uranium enrichment or expansion of its nuclear facilities.

Dubai’s main index advanced 1.7 percent thanks to a 5.1 percent jump in shares of Emaar Properties and a 4.4 percent rise in shares of Emirates NBD Bank.

Shares in low-cost carrier Air Arabia rose 4.9 percent.

The Abu Dhabi index rose 1.2 percent, with First Abu Dhabi Bank shares climbing 0.7 percent and Aldar Properties shares rising 4.8 percent.

The Saudi index rose 0.6 percent and Al Rajhi Bank shares closed with gains of 1.2 percent.

Shares of Saudi Aramco, the oil giant, gained 0.7 percent.

Brent crude futures fell $2.48, or about 3 percent, to $80.69 a barrel by 12:05 GMT, as markets assessed the prospects for a resumption of supplies through the Strait of Hormuz despite volatile market factors and a lack of details on the U.S.-Iran agreement.

Gulf Cooperation Council (GCC) stock markets continued their gains as sentiment improved following the interim agreement. George Pavel, General Manager of Naga.com for the Middle East, said that regional expectations were supported by the prospect of the Strait of Hormuz reopening and the resumption of normal trade and energy flows, even with lower oil prices.

Pavel added that the agreement could pave the way for increased oil production and exports, providing further support to regional markets in the medium to long term.

In Qatar, the index closed trading with little change.

Outside the Gulf region, Egypt's blue-chip index fell 0.5 percent.

The Bahrain and Kuwait stock exchanges were closed for the Islamic New Year holiday. The Amman stock exchange rose 0.2 percent.
