Other People's Money

Other People's Money examines how the modern financial sector has transformed from serving the real economy to primarily trading with itself. Kay traces the evolution of banking and finance from its traditional role in facilitating business and commerce to today's complex web of intermediaries and traders. The book details specific changes in financial markets over recent decades, including the rise of derivatives, securitization, and high-frequency trading. Kay analyzes major financial institutions and explains how their operations have become increasingly disconnected from the needs of businesses and individuals. Through extensive research and insider perspectives, Kay presents the key challenges facing financial reform and regulation in the wake of the 2008 crisis. The narrative covers both technical aspects of modern finance and broader economic implications. The work presents a fundamental critique of the financial sector's current structure while making the case for returning to a simpler, more functional model of finance that prioritizes the real economy. Its analysis speaks to essential questions about the purpose of financial markets in modern society.
