Dubai led gains across most Gulf stock markets on Wednesday after a report said ​the White House believed ⁠it was nearing agreement on a memorandum to end the war with Iran, while ‌falling oil prices weighed on Saudi Arabia's index.

News outlet Axios reported that the U.S. expected Iranian responses on several ​key points in the next 48 hours. A Pakistani source involved in the peace efforts confirmed the report to ​Reuters on ​Wednesday.

"Markets in GCC rebounded as sentiment improved amid calmer conditions in the region and a more reassuring rhetoric from U.S. officials," said Joseph Dahrieh, managing director at Tickmill.

"In the ⁠UAE, a deal could help the country expand on its ambition to raise oil output and exports, which could help support the local stock markets over the long term," he added.
