In recent decades, significant advancements in industry and technology have greatly influenced financial markets. However, criminal organizations exploit these developments to disrupt the stock market and undermine financial structures through fraudulent transactions. This expansion of illicit activities destabilizes the global economy, weakening international laws, regulations, and foreign investments. Given the complexity of financial crimes and the imperative to combat international and terrorist activities, it is crucial to examine the impact of money laundering on the global economy and the approaches of international financial institutions in preventing and confronting this issue. This descriptive-analytical study reveals that money laundering poses a fundamental challenge in the international economic arena. International institutions must oversee financial systems to safeguard the integrity and stability of global finance. This necessitates collaboration among these institutions and countries to combat money laundering effectively, including tracking illicit money flows, enhancing transparency in international banking systems, developing electronic infrastructures, integrating financial information systems, and improving global data.
