In Episode 47 of Monetary Policy Explained with Fexingo, Lucas and Luna dive into the often-overlooked tool of reserve requirements. Once a cornerstone of central banking, reserve requirements have fallen out of favor in many advanced economies — but not everywhere. Lucas explains how the Fed, ECB, and People's Bank of China have diverged on this tool, and why a 0% requirement doesn't mean zero policy impact. They explore the mechanics of required reserve ratios, the multiplier effect, and how China has used reserve requirement ratio (RRR) cuts to inject liquidity — including a recent 50-basis-point cut in early 2026. Luna questions whether reserve requirements still matter when banks can hold excess reserves. The episode includes a practical example: if the required reserve ratio is 10%, a $100 million deposit creates $1 billion in money supply. But in a world of abundant reserves, that textbook multiplier doesn't hold. The hosts also touch on the unintended consequences of high reserve requirements, like disintermediation and shadow banking. A thoughtful episode for anyone who wants to understand a classic tool that still shapes global monetary conditions. #ReserveRequirements #CentralBanks #MonetaryPolicy #FractionalReserveBanking #MoneyMultiplier #FederalReserve #ECB #PeoplesBankOfChina #LiquidityManagement #BankingRegulation #Macroeconomics #Economics #FexingoBusiness #BusinessPodcast #InterestRates #MoneySupply #LucasAndLuna #PolicyTools Keep every episode free: buymeacoffee.com/fexingo
