Financial Systems and Money

Financial Systems and Money

Core Functions of Financial Systems

  • Payments: Facilitating transactions for goods and services.
  • Credit and Liquidity: Providing access to funds. Liquidity refers to how easily an asset can be converted into spendable cash. For example, Mark Zuckerberg might be worth billions, but most of his wealth is tied up in Facebook stock, making him less liquid. To access liquid cash, he would need to sell stock or adjust his compensation package. There can be a significant time lag (days, weeks, months) to convert illiquid assets (boats, cars, securities) into spendable cash.
  • Long-Term and Short-Term Investment: Allowing customers to invest funds for various durations.
  • Transfer Financial Risks: Shifting potential financial losses from one party to another.

Transferring Financial Risk: Insurance

  • Concept: Insurance is a mechanism to transfer risk. For instance, when driving a car, there's a risk of crashing and owing money for damages. Car insurance allows an individual to transfer this financial risk to an insurance company.
  • Actuarial Science: Insurance companies calculate the probability and potential cost of such events using actuarial tables and statistical analysis. This explains why car insurance is significantly more expensive for young men (statistically higher risk of accidents) than for young women.

Understanding Money: Value and Historical Forms

  • Definition of Money: Money is not inherently valuable; its value is derived from collective belief and agreement.
  • Historical Examples of Money/Currency Proxies:
    • Coins/Gold: Still occasionally used. Coins once had ridges to prevent shaving off precious metal (e.g., gold) for illicit re-use, a practice Caesar aimed to stop.
    • Bartering: Exchange of goods or services directly, often implicitly based on time and labor value rather than an arbitrary dollar amount.
    • Alcohol (Whiskey Rebellion Example): In early American history, alcohol (like whiskey) served as a de facto currency, especially in rural areas. Farmers would convert bulky crops (e.g., three bushels of corn, the maximum a mule could carry) into smaller, easier-to-transport gallons of alcohol. The value was understood in terms of the corn it took to produce it.
      • The Whiskey Rebellion (Sidebar): Alexander Hamilton, a key figure in early American finance, engineered a complex tax code that was initially rejected by Congress. To force its passage, he deliberately imposed a tax on small-batch whiskey production (exempting large industrial makers), knowing it would provoke outrage among farmers who used whiskey as currency. This led to assaults on tax collectors (tarring and feathering), creating a need for a federal armed force. Congress, needing to fund this force, was then compelled to pass federal taxes, allowing Hamilton to introduce his tax code. This demonstrates how a commodity, like alcohol, could function as money.
    • Livestock: Animals held intrinsic value and could be traded.
    • Seashells/Sand Dollars: Natural items used as currency in various cultures.
    • Salt: The phrase "worth his salt" originates from a time when salt was a valuable commodity used as payment.

Currency Terminology

  • Currency: The proper term for money, serving as the medium of exchange for goods and services.
  • Government-Issued (Fiat) Currency: Historically, most currencies have been issued by governments. This is a crucial distinction when discussing cryptocurrencies.
  • Internal Value: The purchasing power of a currency within its own country (e.g., 33 for a gallon of milk in the US).
  • External Value: The value of a currency relative to other currencies, determined in international foreign exchange (forex) markets. This value fluctuates based on trade balances, economic performance, and global political events (e.g., US dollar value dropping due to Middle East conflicts and oil prices). These markets allow for speculative trading (gambling) on currency movements.

Stocks

  • Definition: Represents a portion of ownership in a company or entity. A stock owner is a shareholder.
  • Shareholder Types:
    • Majority Shareholder: Owns a significant portion of a company's stock.
    • Controlling Shareholder: Owns over 50%50\% (e.g., 51%51\%) of a company's stock, effectively controlling the company's decisions.
  • Value Determination: Stock value is primarily based on the perceived potential future value of the company, not merely its current value. Buying pressure (more people wanting to buy) drives prices up, while selling pressure (more people wanting to sell) drives prices down, following complex but fundamentally simple algorithms.
  • Dividends: Some stocks issue dividends, which are a share of the company's profits paid to shareholders, providing a return (e.g., a 3%3\% or 4%4\% dividend) regardless of stock price fluctuations.
  • Brokerages and Exchanges: To buy or sell stocks, individuals typically go through a brokerage firm (online or physical) that has access to stock exchanges (e.g., New York Stock Exchange (NYSE), Nasdaq, Chicago Mercantile Exchange (CME)). These brokerages hold "seats" at the exchanges that enable trading.
  • Types of Sales:
    • Call Option: Buying a stock with the expectation that its price will increase.
    • Put Option: Selling a stock with the expectation that its price will decrease.

Loans

  • Mechanism: Typically executed through depository accounts (banks). Banks gather funds from savings accounts (offering low returns, e.g., 0.5%0.5\%) and lend them out at higher interest rates (e.g., 9%-10%9\%\text{-}10\% for loans, up to 29%29\% for credit cards), profiting from the difference.
  • Secured Loans (e.g., Mortgages): Backed by collateral (e.g., a house). If the borrower defaults, the lender can seize and sell the collateral to recover the funds. This lower risk leads to lower interest rates.
  • Unsecured Loans (e.g., Credit Cards): Not backed by specific collateral. Based on the borrower's credit history and credit score (a measure of past repayment reliability). Due to higher risk of default, unsecured loans carry much higher interest rates. The high interest charged to all borrowers effectively covers the losses incurred from defaults by some.

Options

  • Definition: A contract that gives the holder the right, but not the obligation, to buy or sell an underlying asset (like a stock) at a specified price (the strike price) on or before a certain date (the expiration date).
  • Historical Origin: Traced back to ancient Greece (4th century BC). A philosopher predicted a bumper olive crop and, instead of buying presses, bought contracts to use existing olive presses' capacity at a pre-negotiated, lower price. This allowed him to profit significantly when the bumper crop materialized, and he exercised his option at a favorable rate.
  • Modern Function: Electronically traded contracts. A single option contract typically covers 100100 shares of stock.
  • Leverage: Options allow for significant leverage. For a small initial cost (e.g., 44 for an Apple option contract), one can control a large number of shares. A small percentage increase in the stock price (e.g., Apple jumping from $1,000 to $1,400) can yield massive returns (e.g., turning $4 into $10,000 if the option was to buy at $1,100).
  • Insider Trading Risk: Due to high leverage, options are a common tool for illegal insider trading. Knowing about an upcoming event that will cause a stock jump allows one to buy cheap options and profit immensely. This is why there's concern about congressional members trading stocks, as they may have privileged information.
  • Put Options and Risk: Betting on a stock price decrease. One borrows stock, sells it, anticipating buying it back at a lower price to pocket the difference. This can be extremely dangerous: if the stock price goes up instead of down, the option holder must cover the entire gain when the option expires, potentially leading to massive losses (e.g., the GameStop phenomenon where short sellers (using put options) faced huge losses as the stock price unexpectedly surged).

Financial System Structure: Major Buckets

  • Banking and Credit: Traditional banks and credit unions.
  • Securities, Commodities, Financial Investments: Stocks, bonds, mutual funds, etc.
  • Insurance: Risk transfer mechanisms.

Depository Institutions

  • Role: Banks and credit unions obtain federal or state charters to operate. They provide services like loans, credit cards, and depository (savings/checking) accounts.

Clearing Houses

  • Function: Facilitate the interbank settlement of transactions. Instead of sending each individual transaction immediately, banks keep a ledger of all incoming and outgoing funds throughout the day.
  • End-of-Day Settlement: At the end of the day, all transactions are aggregated, and only the net difference between banks is transferred through a clearing house. For example, if Bank of America processes many checks to Citibank clients, and Citibank processes many checks to Bank of America clients, the clearing house calculates the net amount (e.g., Bank of America owes Citibank $52,000) to be transferred.
  • Fragility: Clearing houses are crucial for the stability of the banking system. Their reliance on interconnected computer systems and internet infrastructure introduces fragility; a system failure could severely disrupt financial settlement.
    • ACH (Automated Clearing House): Used for bulk electronic payments like direct deposits.

Central Bank (Federal Reserve)

  • Role: Manages the nation's monetary policy, regulates the amount of currency in circulation, and influences the prime interest rate (which impacts commercial lending rates).
  • Currency Integrity: Federal Reserve branches (e.g., in Chicago or Boston) maintain the integrity of physical cash currency by removing damaged bills (and destroying them) and identifying counterfeit currency.

Brokerages and Exchanges

  • Brokerages: Firms (online or physical like Edward Jones) that act as intermediaries, giving individuals access to financial markets.
  • Exchanges: Physical locations (like NYSE on Wall Street) or electronic platforms where securities, commodities, and other financial instruments are bought and sold. Brokerages have
