The Middle East is shifting from oil to oceans, and blue bonds are becoming a key tool for economic diversification. Driven by Saudi Arabia and the United Arab Emirates, the region's sustainable bond market is expected to reach $20 billion to $25 billion by 2026. Blue Sukuk is a unique innovation that combines Islamic finance with ocean conservation, helping sustainable Islamic bonds set a record of $11.4 billion in 2025. The region is working to regulate these instruments and provide funding for projects such as renewable energy and seawater desalination, aiming to establish a global benchmark for transparent, asset-backed blue finance.
