Dependent variables include cross-border trade volume and investment flows, while independent variables capture CBDC adoption, regulatory quality, and payment system efficiency. Control variables, such as GDP, exchange rates, trade openness, and inflation, are included to account for macroeconomic and institutional factors. Comparative analyses examine how differences in market maturity, institutional quality, and regulatory frameworks influence the effectiveness of CBDCs in facilitating trade and investment. Findings suggest that CBDC implementation can enhance efficiency, reduce transaction costs, and improve liquidity management in cross-border trade, while also influencing investor behavior and FDI allocation decisions. The impact is moderated by institutional quality, with developed economies benefiting from greater transparency and stronger regulatory frameworks, whereas emerging economies may face higher operational and adoption risks.Central Bank Digital Currencies (CBDCs) are emerging as a transformative innovation in the global financial landscape, offering the potential to reshape cross-border trade finance and international investment flows. Traditional payment systems and trade finance mechanisms often face inefficiencies, including high transaction costs, slow settlement times, and exposure to currency volatility, which can constrain foreign direct investment (FDI) and portfolio investment activities. This study investigates the impact of CBDC adoption on cross-border trade and investment patterns, with a comparative focus on emerging economies (BRICS) and developed economies (OECD).CENTRAL BANK DIGITAL CURRENCIES
