This document discusses the concept of a borderless economy from an Islamic finance perspective. It argues that while modern banking products like ATMs and credit cards allow borderless transactions, corporate banking is still limited by national borders. However, some borderless corporate banking may already exist in international markets. The document suggests that with internet-based borderless payments, the need for banks and international reserve currencies as intermediaries in global trade may decline. It proposes alternatives like governments or book-based settlement between OIC countries' central banks as intermediaries in international trade.
