Today's economic and financial system is being reshaped within the framework of technological transformation, digitalization, sustainability, global risks, investor behavior and access to finance. Financial markets are no longer only for capital accumulation and resource allocation; uncertainty, expectation, trust, crisis, innovation and sustainable development dynamics.  This book, titled Current Studies in the Field of Finance, brings together scientific studies that contribute to current debates on finance, banking, capital markets, digital economy, sustainability and business performance.

In the first part of the book, Melik Kamışlı examines the spread of IoT-themed volatility shocks to telecommunications sectors and reveals the effects of digital transformation on financial markets. In the second part, Naci Yılmaz examines the problems faced by SMEs in accessing finance, such as lack of collateral, information asymmetry and limited credit history; fintech, microfinance, crowdfunding, angel investors and public supports. In the third part, Burak Korkmaz analyzes the long-memory characteristics of the volatility in the cryptocurrency markets through Bitcoin, Ethereum, Litecoin and Ripple. In the fourth chapter, Oktay Turan and Batuhan Medetoğlu discuss the causality relationships between the stock markets of the MINT countries and the VIX index. In the fifth chapter, Sonay Akar and Gizel Busem Sayıl examine the relationship between consumer confidence index and stock market indices in the context of BRICS countries with ARDL and NARDL models. In the sixth chapter, Semra Demir and Halil İbrahim Gökgöz contribute to the sustainable finance literature by analyzing the relationship between green bonds and market-based investor sentiment indicators. In the seventh chapter, Kaşif Batu Tunay and Necla Tunay comprehensively evaluate the theoretical approaches, empirical findings and current risks of banking crises. In the eighth chapter, Meltem Keskin discusses the transformation created by fintech and digital banking in financial ecosystems in a theoretical framework. In the ninth chapter, Lokman Tütüncü examines the public offering processes in Borsa Istanbul through investor allocations, fund utilization purposes and low pricing dynamics. In the tenth chapter, Şinasi Furkan Yıldırım and Berk Yıldız analyze the impact of working capital components and operational structure on financial performance in cruise companies. In the eleven chapter, Cansu Çilingir Kara and Melek Özlem Ayas Cin discuss the relationship between remittances, financial depth and ESG performance in OECD countries. In the last part, Kemal Özdemir investigates sectoral differentiation in ratio analysis in terms of BIST.

When the studies in the book are evaluated together, it is seen that financial systems cannot be explained only by traditional market mechanisms. Technological innovations, digital infrastructures, sustainability goals, investor sentiment, global risk indicators, and business-level financial decisions are intertwined. In this respect, the book aims to present an interdisciplinary, data-based and up-to-date perspective in the field of economics and finance. I would like to thank all the authors who contributed to the preparation of the work, for their support in the preparation process for publication. Asst. Prof. Dr. Kürşad ÖZKAYNAR and the staff of Özgür Publications. I hope that the book will be useful to academics, graduate students, financial sector professionals, policy makers and all readers interested in the field of economics and finance.
