As is well known, the economy is a rapidly developing field and the dynamism in the financial sector, which is a sub-discipline of the economy, is much higher. The diversity of products and services in financial markets has reached a dizzying pace, especially in the post-2008 period when digital currencies entered our lives. In addition, it is seen that green finance practices have become much more widespread thanks to the shift towards renewable energy resources in line with sustainable development goals in the face of climate change caused by global warming.  Therefore, Current Financial Developments and Practices, which is also the title of our book, consists of studies that reflect the striking developments in the world of finance, especially in the last two decades. In this context, the book, An Essential Financial Technique for Sustainable Development: A Literature Review on Green Finance, Measuring the Risk of Financial Failure of Businesses Operating in the Air Transportation Sector in Turkey, The Place of Digital Participation Banks in the Participation Banking Sector, Stock Market Index Option Contracts in the Framework of Recent Financial Developments, Determinants of Liquidity Risk in the Banking Sector: Evidence from Turkish Deposit Banks, The Relationship between Green Bonds and Renewable Energy Financing in Financial Markets, The Impact of Price Changes in Precious Metals on Stock Returns: A Study on the BIST 100 Index, Evaluation of Securities Investment Funds with Beta Timing Ratio. This book is a remarkable guiding work on the most popular topics of the last period in the world of finance.  I would like to thank Assitant Professor Kürşad Özkaynar for his endless labor and support to the authors in the preparation of the book for publication
