The Economics of Digital Money

Money as a physical asset overcomes barter's double coincidence of wants by serving as a medium of exchange, unit of account, and store of value, in the orthodox view.

See how modern money acts as a financial liability issued by the state, a promissory note accepted for taxes, and how currency differs from physical assets.

Modern money is fiat, legal tender created by government spending rather than taxes, with taxes destroying money and bonds used to control inflation and interest rates.

Explore the modern money hierarchy from household IOUs to nonbanking financial institutions, bank deposits, and state money, and explain how banks create money via deposits and reserves.

Explore how bank money, via deposits and central bank reserve accounts, flows from government spending to the nonbanking private sector, and back through taxes, balance sheets, and deficit financing.

Examine how interbank settlements occur using reserve money and central bank reserve accounts, and explore how banks access reserve money through government spending, the money market, and repo transactions.

Endogenous money theory shows banks create money by lending and creating deposits, not just intermediaries. The lecture explains deposit creation, interbank settlements, and the money hierarchy.

Commercial banks create deposits and settle interbank payments through central bank reserves, making bank money dominant; the lecture explains reserves, deposits, and the endogenous monetary view and regulation.

Explore what digital money is, the medium of exchange that enables cross time and space trade, the rise of electronic currency, and who controls money creation in modern economies.

Discover how the digital payments system settles debt through state money, commercial bank deposits, wallets, upi, central bank digital currencies, and crypto currencies, with rapid electronic transfers replacing checks.

Study the digital payments system, contrasting payments banks with commercial banks and noting UPA enables bank-to-bank transfers while e-wallets handle wallet-to-wallet payments.

Compare cryptocurrencies with modern money and other digital money, showing how digital money enables fast, convenient transfers, while cryptocurrencies remain decentralized asset transfers with limited anonymity.

Explore why people demand cryptocurrencies, including low fees, fast transfers, and wealth storage away from government control, while examining speculation, fixed supply, and the limits of replacing modern money.

Examine Bitcoin's fixed 21 million supply and Ethereum's uncertain future, and how mining energy drives price volatility. Compare crypto to gold and modern money, noting supply constraints, stability, and fluctuations.

Examine El Salvador's Bitcoin legal tender within a dollarized economy, where the US dollar serves as unit of account and money, not sovereign modern money.

Using the dollar as the unit of account, El Salvador makes both dollars and bitcoin legal tender. Setting the bitcoin rate by the market avoids fixed ratios and bad money.

El Salvador kept the dollar as the unit of account while allowing Bitcoin as legal tender, showing volatility risks, potential internal devaluation, and IMF bailout context.

Explore central bank digital currencies as digital cash, and examine their monetary policy implications for fintech, commercial banking, and a cashless economy, including negative interest rate policy.

Explore how CBDCs reshape modern money, as fintech and e-wallets centralize data, raise privacy concerns, and juxtapose crypto currencies and energy use with bank competition.

Enable the nonbanking private sector to hold central bank balances directly, and explore how CBDCs could undermine the deposit creation function of commercial banks.

Explore how CBDCs could work symbiotically with the commercial banking system or dominate the financial architecture, reshaping lending, payments, and privacy.

Explore how central bank digital currencies could bypass the commercial banking system, shift deposit choices, and reshape monetary policy transmission through direct access for the nonbanking private sector.

China's digital currency electronic payment (DCEP) is a central bank digital currency that replaces cash, preserves commercial banking, and enables controllable anonymity while raising cross-border and dollar dominance questions.

Examine why the dollar remains the dominant international currency after Bretton Woods, and why the world accepts the U.S.'s exorbitant privilege amid deficits and liquidity needs.

This lecture examines how dollar dominance relies on deficits, reserves, and global markets, and asks whether renminbi shifts or central bank digital currencies could reshape this balance.

Clarify money as physical assets and central-bank liabilities, and show how modern digital money from interbank settlements and government spending to wallets and crypto fits the financial system.
