Lecture Notes: Investment, Hedge Funds vs Money Markets, and the Banking System

Hedge funds vs. money market funds

  • Hedge funds tend to be higher-risk investments and are typically reserved for high net worth individuals and institutional investors. They are not generally accessible to small investors. Major players include large institutional investors, core investment banks, and sovereign or corporate actors. The idea is that hedges funds attract the big bets and significant capital rather than everyday retail participation.
  • Money market funds are presented as the opposite in terms of accessibility and liquidity. They are available to smaller investors and emphasize higher liquidity and simpler withdrawal terms.
  • Risk perception: hedge funds are described as riskier, while money market funds are framed as comparatively safer and more liquid—though some money market funds can still carry risk.
  • The term hedge is discussed conceptually: hedging is about reducing or eliminating risk, though the speaker notes a practical tension between hedging and risk in real-world investing.
  • Real-world players mentioned: Bill Gates or other billionaires and major corporate traders are cited as examples of the kinds of investors who participate in hedge funds; sovereign bonds from other countries are cited as another hedge fund domain.
  • The speaker contrasts hedge funds with traditional money market investments, noting liquidity, access, and risk profiles as the main differentiators.
  • The session frames the “definition” challenge of hedge funds in contrast to money market funds as an ongoing topic for the next class.

Two major topics to come next: interest rates and liquidity

  • The instructor announces that the next class will tackle one of the hardest topics: interest rates and how they are determined.
  • Two perspectives on interest-rate determination are introduced:
    • The demand-supply view of vulnerable funds (or loanable funds): this is described as a fixed-cost framework and ties to the supply and demand for funds that can be borrowed.
    • The liquidity preference view (and the long-run liquidity preference theory): this is the other framework for thinking about interest rates.
  • The instructor contrasts two questions:
    • Are interest rates determined by the supply and demand for vulnerable funds (loanable funds)?
    • Are interest rates determined by the demand and supply of money? (liquidity preference)
  • The goal is to help students understand which framework better explains rate determination, and the idea that many people cannot clearly distinguish between these two perspectives.

Quick shift to money and payments: account-based vs token-based money

  • A move back to day-to-day banking transactions (Best Buy example) illustrates the difference between account-based money and token-based money.
  • Account-based money: payments are traceable to specific accounts; transactions can be traced to who paid whom and through which bank, as in check payments.
  • Token-based money: transactions may occur without explicit traceability to a specific account or payer; cryptocurrencies are given as an example where transactions are not always easily traced to a single originator or recipient.
  • The professor throws in a prompt about a bonus quiz on account-based vs token-based money in the next session to reinforce this distinction.

Check clearing, deposits, and the basics of money flow

  • The session revisits the check clearing process, emphasizing that checks are account-based money when moving through the banking system.
  • The flow of funds when writing a check: you write a check on your bank; Best Buy receives the funds; the banks coordinate through the Federal Reserve System for clearing.
  • When you write a check, deposits at Best Buy’s bank increase, while your own bank’s deposits decrease; the transfer involves reserves moving between banks, with the Fed acting to settle these interbank movements.
  • The talk ties the check-clearing process to the broader structure of the monetary system and how reserves are adjusted across banks and the Federal Reserve.

A broader look at money, reserves, and the Federal Reserve

  • The Federal Reserve System (the Fed) is introduced as a central bank with 12 district banks, designed to avoid excessive political control and to maintain monetary stability.
  • The independence of central banks is argued as a hedge against irresponsible inflationary pressure, with examples of countries that struggle with inflation when central banks lack independence (e.g., Turkey, Venezuela).
  • The speaker emphasizes that central banks are creatures of Congress; they are designed to be insulated from direct political control, though not absolutely independent.
  • The role of the Fed in reserves: banks hold reserves either as vault cash or as deposits at the Federal Reserve; these reserves are used to clear checks and settle interbank payments.
  • Two components of reserves are highlighted:
    • Deposits at the Fed (reserve deposits)
    • Vault cash and other cash held by banks (vault cash)
  • The Fed’s independence is tied to inflation control: independent monetary policy tends to reduce inflation risk relative to systems without such independence.
  • The discussion uses real-world anecdotes to illustrate how political dynamics can influence inflation and monetary policy, and cautions against over-attributing macro outcomes to any single administration.

The money supply: M1, M2, M3, and what counts as money

  • The money supply is treated as a stock, not a flow; it represents a given quantity of money at a point in time.
  • The accounting analogy is used to explain money as a stock of assets and liabilities in the economy.
  • M1 is defined in the lecture as currency in circulation plus checkable deposits (demand deposits) and other liquid forms that can be readily spent. The speaker emphasizes two key money forms in M1:
    • Currency in circulation (coins and Federal Reserve notes)
    • Deposits in banks that are readily spendable (checkable accounts)
  • The speaker notes that most of the money supply is in deposit accounts rather than physical cash. The idea that deposits are a major part of money supply is stressed; currency outside the Federal Reserve System is also discussed as a component of money in circulation, with a notable emphasis that much currency is held outside the U.S. and that $100 bills are a common denomination used globally.
  • The distinction between cash (currency) in circulation and deposits is reinforced: deposits are intangible and not directly observable, whereas cash can be seen and touched.
  • The dollar’s global role and fluctuations are discussed in the context of confidence and crisis dynamics; the speaker notes that in crises, the dollar often appreciates, but recent trends show a period where global confidence and currency valuations have shifted in different ways due to various supply and demand factors.
  • The idea that most of the monetary base is held outside the U.S. is highlighted, along with the observation that currency is not net created locally but flows internationally.
  • The lecturer introduces the broader structure of money measurement beyond M1, hinting at M2 and M3 (which include broader measures like savings deposits, money market funds, and other near-money assets), but the main focus remains on M1 as the core, immediately spendable money.

How banks create money: loans and deposits

  • A central idea is that banks create money through lending: when a bank approves a loan, it creates both an asset (the loan) and a liability (a deposit in the borrower's account).
  • Example narrative: If you want to buy a $1,000 bicycle and borrow from a bank, the bank does not physically conjure cash first; instead, it creates a $1,000 deposit in your account and records a $1,000 loan on its books.
    • Asset side: the bank holds the loan as an asset worth $1,000 because you owe the bank that amount.
    • Liability side: the bank creates a new deposit (your checking account) worth $1,000, which is money you can spend.
  • This process increases the money supply (M1) through the deposit that has been created, even though no physical cash has necessarily entered circulation.
  • The example emphasizes that money is largely created in the form of deposits rather than by printing currency; most of M1 consists of deposits rather than cash in wallets or in vaults.
  • The distinction between cash in vaults and deposits at the Fed is important for understanding reserves and the money multiplier concept, even though the simple intuition is that banks can create money via lending.

Practical examples of money flows and deposits

  • House purchase example:
    • Suppose you buy a $300,000 house with $50,000 of your own money (equity) and borrow $250,000 (debt) from a mortgage lender.
    • On your balance sheet: assets increase by the house value ($300,000); equity contributes $50,000, with the remaining $250,000 financed by debt (mortgage).
    • On the lender’s balance sheet: the loan of $250,000 is an asset for the bank; deposits increase correspondingly as the borrower’s funds are deposited.
    • The transaction illustrates how asset growth (the house) is financed by a combination of equity and debt, while the money supply expands via new deposits created by the loan.
  • Best Buy check example:
    • You write a $100 check to Best Buy; Best Buy deposits the check into its bank.
    • The recipient's bank receives the funds and credits Best Buy’s deposits, while your bank reduces your checking account by $100.
    • The transfer increases Best Buy’s deposits and reduces your deposits; reserves move through the interbank settlement system managed by the Fed.
  • The point of these examples is to illustrate how everyday transactions involve the movement of reserves and deposits, reinforcing that much of the money supply exists as deposits rather than currency in hand.

Currency, deposits, and the role of reserves

  • Currency in circulation (cash) includes Federal Reserve notes and coins held by the public; this is a component of M1 but is only a portion of the money supply overall.
  • Deposits (checkable deposits) are typically the larger component of the money supply, and the money supply is largely made up of intangible balances rather than physical cash.
  • The reserves banks hold consist of two main components:
    • Vault cash (cash physically held in the bank)
    • Deposits at the Federal Reserve (reserve accounts)
  • When a customer writes a check or a transaction occurs, reserves are adjusted across banks so that the interbank settlement balances are maintained; this affects the distribution of reserves but not necessarily the total size of the money stock in all cases.
  • The distinction between reserves as cash held in vaults and deposits at the Fed is important because banks can meet liquidity demands by shifting between these two reserve forms, and the Fed uses these reserves to manage monetary policy and the money supply.
  • The speaker notes that most currency is not held in the United States but is held abroad, with $100 denomination bills being particularly prominent in international holdings.
  • The Federal Reserve Notes are issued by the Federal Reserve Banks, not by the Treasury; the central bank is designed to function independently of direct political control, though it remains a government-created entity.
  • The talk emphasizes that the currency in circulation and the deposits in banks together form the core money supply, with a heavy emphasis on deposits as the dominant form of money in everyday life.

The big picture: inflation, policy, and real-world dynamics

  • Inflation is discussed in the context of monetary policy independence; countries with less independent central banks tend to experience higher inflation more frequently.
  • Historical anecdotes are used to illustrate how inflation can rise due to supply shocks (e.g., COVID-related supply chain constraints) or policy choices; the speaker notes that inflation dynamics are often influenced by global events and structural changes, not solely by the policy of a single administration.
  • The 1997–Feb 2001 period (and other eras) are mentioned as examples where macroeconomic outcomes can be the result of many factors, including productivity, external shocks, and broader structural trends, rather than a single policy decision.
  • A broader point is made about how money supply, reserves, and the banking system interact with economic activity, the real economy, and inflation expectations, underscoring the importance of understanding the mechanics of money creation and central banking.

Bonus notes and exam tips mentioned in the lecture

  • There may be a bonus quiz on the article about account-based vs token-based money, and on the distinction between money-based and asset-based transactions.
  • Students are reminded to print their name and date on handouts to avoid confusion during grading, and to be mindful of cheating in the classroom context.
  • The instructor notes that textbooks may not be fully up-to-date with digital money developments and that he provides additional material to stay current, which can be more useful than a traditional textbook in a rapidly changing field.
  • There is a suggestion that the next class will cover the most challenging topic in macro/money: the precise mechanism behind interest rate determination, including the concepts of loanable funds vs money demand and the liquidity preference framework, with a focus on how these theories affect real-world rates and policy.

Key formulas and concepts to remember

  • Money stock concept (stock vs flow): the total amount of money in the economy at a point in time, not the rate of spending.
  • M1 definition (simplified for this lecture):
    M1=extCurrencyincirculation+extDemanddeposits(checkabledeposits)+extTraveler′schecks(ifapplicable)M_1 = ext{Currency in circulation} + ext{Demand deposits (checkable deposits)} + ext{Traveler's checks (if applicable)}
  • Reserves definition (two components):
    R=R<em>extvault+R</em>extFedR = R<em>{ ext{vault}} + R</em>{ ext{Fed}}
  • Bank money creation (loan-deposit creation): when a bank issues a loan of amount $L$ to a borrower, it creates:
    • an asset: the loan ($L$) on the bank’s books
    • a liability: a deposit ($L$) in the borrower’s account
  • Balance sheet intuition for a loan-financed asset:
    • Asset side: House worth $300{,}000$ (assets)
    • Financing side: $50{,}000$ equity (owner's funds) + $250{,}000$ debt (mortgage)
  • The flow of funds in a check transaction:
    • Payer’s bank reduces the payer’s checking balance by the check amount
    • Payee’s bank increases the payee’s deposits by the same amount
    • Interbank reserves move through the Fed to settle the transfer

Connections to broader topics

  • Link to monetary policy: independence of the central bank reduces inflation risk and stabilizes the macroeconomy, while political pressures can lead to undesirable inflation dynamics.
  • Link to real-world relevance: understanding money creation helps explain how credit conditions affect consumer spending, housing markets, and investment activity.
  • Ethical/practical implications: better financial literacy about how money is created and moved can help individuals make informed decisions and understand the limitations of different investment vehicles (hedge funds vs money market funds).
  • Real-world relevance: the discussion connects everyday banking activities (checking, deposits, and loans) to large-scale mechanisms (money supply, bank reserves, and inflation dynamics), showing how micro-level actions contribute to macro-level outcomes.
