The Arab Monetary Fund published the 66th edition of its Arab Capital Markets Monthly Bulletin for May 2026, showing mixed performance across Arab exchanges as geopolitical challenges and lower oil prices weighed on a number of regional markets. The AMF Composite Index was broadly stable but edged down 0.05% from the previous month, with eight Arab stock exchanges posting gains and six recording declines. The Tunis Stock Exchange led regional gains with a 10.04% rise, followed by the Damascus Securities Exchange at 7.99%, the Amman Stock Exchange at 3.46%, the Egyptian Exchange at 1.73% and the Casablanca Stock Exchange at 1.57%. Total market capitalization across Arab capital markets fell 0.31% to about USD 4.42 trillion at the end of May 2026, a drop of around USD 13.72 billion from the previous month, despite higher market capitalization in 11 exchanges. Trading activity also weakened, with the value of traded securities falling 26.42% to about USD 76.95 billion, reflecting lower volumes in several major markets, particularly the Saudi Exchange and the Egyptian Exchange. The bulletin noted that this performance contrasted with improvements in most advanced markets during May 2026, as geopolitical risks, lower oil prices and unchanged policy rates by major global central banks continued to shape sentiment.
