ரகசியம் - How Banking Really Works | Full Truth Explained | Jayasim Jayakumar

Have you ever wondered what really happens to the money you deposit in a bank? The truth is, your cash doesn't sit safely in a vault — it exists mostly as numbers in a ledger. This documentary traces the fascinating evolution of banking from ancient Mesopotamia, where temples in present-day Iraq stored grain and extended loans to farmers, through the wooden benches of 11th-century Italy where the very word "bank" was born from the Italian "banco." You'll discover how the modern fractional reserve banking system allows banks to create new money simply by issuing loans, how the Reserve Bank of India and central banks worldwide use tools like the Repo Rate and Quantitative Easing to steer entire economies, and why the entire system rests on one surprisingly fragile foundation — trust. From the Yes Bank crisis of 2020 to the origins of Bitcoin born from the ashes of the 2008 Global Financial Crisis, this is the complete story of how money, banking, and power are truly connected. #jayasimjayakumar #jayasim #banking #howbankswork #fractionalreservebanking #moneycreation #centralbank #reservebankofindia #rbi #bitcoin #bankrun #yesbank #monetarypolicy #financialsystem #indianeconomy #bankingtamil ---------------------------------- 🔗 Register today for Crypto 101 course : https://geni.us/crypto-101 💥 Use code JJGET20 for a flat 20% off on any course! ---------------------------------- COMMUNITIES: 💰 Crypto Telegram Community: https://geni.us/crypto-with-jayasim - for weekly updates ---------------------------------- DISCLAIMER: ⚠️ Read through my YouTube disclaimer policy here: https://jayasim.com/disclaimer If you identify any inaccuracies or have concerns, we encourage you to contact us at contact@jayasim.com (subject: Feedback on [Video Title]) so we can address and resolve the matter promptly and amicably. 🌐 Link to all sources: https://jayasim.com/video-resources 📝 Factual errors will be noted on this page - https://jayasim.com/corrections TIMESTAMPS: 00:00 Introduction 04:53 Origin of Banks in Ancient History 07:38 The Basic Business Model of Banks 09:40 Bank Runs and Cash Reserve Ratio 11:06 Fractional Reserve Banking 13:59 Regulations and Constraints 16:17 The Fragility of Trust 18:19 How Banks Earn Beyond Interest 23:49 Role of the Central Bank 31:43 The Cracks That Led to Bitcoin
