Study Notes on Market for Loanable Funds and Banking

Market for Loanable Funds

Learning Objective

  • Forecast the long-run real interest rate.

  • Understand how the real interest rate is shaped by various economic factors.

Overview of Interest Rates

  • Short Run vs. Long Run:

    • Short-run interest rates fluctuate monthly due to adjustments by the Bank of Canada to stabilize the economy.

    • Long-run real interest rates evolve over years, influenced by the balance of saving and investment.

Key Concepts

  • Market for Loanable Funds:

    • This is the market where savers provide funds to businesses that wish to borrow money for investment.

    • It determines the equilibrium real interest rate and quantity of investment.

Components of the Market for Loanable Funds

  • Savers: Individuals or entities that supply funds, seeking to earn interest.

  • Investors: Businesses or individuals demanding funds to invest in capital.

  • Financial Sector: Consists of banks, the bond market, and the stock market, facilitating transactions between savers and investors.

Price of Loans

  • The real interest rate is the cost of borrowing; it reflects real resources paid by the borrower for loan use.

Supply and Demand for Loanable Funds

  • Supply Curve:

    • Upward-sloping; as the real interest rate increases, the incentive to save increases.

    • Shifts: A shift to the right (increase in saving) leads to a lower real interest rate, while a shift to the left (decrease in saving) leads to a higher real interest rate.

  • Demand Curve:

    • Downward-sloping; as the real interest rate rises, fewer investment projects remain profitable.

    • Shifts: Increased investment demand shifts the curve to the right (higher interest rates), while decreased demand shifts it to the left (lower interest rates).

Equilibrium in the Market for Loanable Funds

  • The equilibrium real interest rate is established where the supply and demand curves intersect.

  • This rate reflects average conditions in the economy, referred to as the neutral real interest rate, occurring when the economy is neither over nor under its potential.

Factors Affecting the Supply of Loanable Funds

  • Personal Saving Rates:

    • Increases in tax incentives or retirement savings increase personal savings, shifting supply to the right and reducing the neutral interest rate.

    • Conversely, tax disincentives can decrease savings, shifting supply left and increasing the neutral interest rate.

  • Government Budget Surplus/Deficit:

    • A surplus indicates the government is saving, increasing the supply of funds.

    • A deficit indicates dissaving, reducing available funds and possibly leading to crowding out of private investment by raising interest rates.

  • Global Shocks (Foreign Saving):

    • Increases in foreign savings can occur due to changes in global economic conditions, shifting supply to the right and reducing real interest rates.

Shifts in the Demand for Loanable Funds

  • Technological Advances: Enhance productivity of capital and increase the demand for loanable funds.

  • Expectations of Future Revenues: Optimistic expectations boost investment demand, shifting the demand curve to the right.

  • Corporate Tax Cuts: Allow businesses to retain more profits, increasing investment and shifting the demand curve rightward.

  • Lending Standards and Cash Reserves: Easier lending standards increase demand for loans, while larger cash reserves among businesses can reduce borrowing needs.

Long-Term Trends Impacting Demand for Loanable Funds

  • Slowing population growth reduces the need for investment.

  • Increasing prevalence of technology firms, which require less physical capital.

  • Reductions in costs for capital equipment decrease the required investment amounts.

Practical Applications: How Economic Conditions Affect Neutral Real Interest Rate

  • Examining factors that cause shifts in supply and demand can aid in predicting changes in interest rates.

  • Various scenarios illustrate how policy changes, economic conditions, or shifts in consumer behavior can adjust both the supply and demand scenarios.

Role of Banks in the Financial System

  • Definition: Banks operate as intermediaries between savers and borrowers, facilitating the flow of funds, and providing various services.

Functions of Banks

  1. Pooling Savings: Collect funds from multiple savers to lend to borrowers, allowing smaller savers to benefit from interest.

  2. Spreading Risk: Diversify loans across many borrowers to minimize potential losses from defaults.

  3. Solving Information Problems: Assess borrower creditworthiness through detailed evaluation processes.

  4. Providing Payment Services: Facilitate transactions, making financial interactions simpler and safer.

  5. Maturity Transformation: Borrow from savers in short-term deposits to finance long-term loans.

Bank Runs

  • A condition where numerous depositors withdraw funds simultaneously, potentially leading to a bank's collapse, revealing the vulnerability of banks owing to liquidity mismatches.

  • Deposit insurance mitigates risks of bank runs by ensuring depositors can retrieve their funds even during financial instability.

The Bond Market

  • Bonds serve as instruments through which corporations and governments raise funds by issuing debt.

  • Components and Functions:

    1. Channels funds from savers to borrowers.

    2. Funds government debt through bond issuance.

    3. Distributes risk among numerous investors.

    4. Creates liquidity by allowing bonds to be resold in the market.

Risks Associated with Bonds

  1. Default Risk: Risk that the issuer may not be able to repay principal or interest.

  2. Term Risk: The risk related to future interest rates affecting bond returns.

  3. Liquidity Risk: Potential difficulty in selling the bond without losing value.

Government Bonds Safety

  • Considered safe due to government backing, with low default risk, but some political risks can arise.

Stock Market Dynamics

  • Stocks represent partial ownership in a company, and their prices reflect the present value of expected future cash flows or profits.

  • Profits can be returned to shareholders as dividends or reinvested into the company, affecting stock valuations across different periods.

Functions of Stocks

  1. Channel funds to companies for investments.

  2. Spread business risk among numerous shareholders.

  3. Reallocate control of corporate governance among shareholders.

Stock Valuation Techniques

  • Fundamental Analysis: Evaluating stock based on its intrinsic value derived from projected future profits, discounted to present value.

  • Relative Valuation: Assessing stock value against comparable entities within the industry.

Comparing Stocks and Bonds

  • Bonds provide fixed returns but no ownership control; stocks offer variable returns with potential dividends and voting rights.

Market Efficiency and Stock Prices

  • The efficient markets hypothesis suggests that stock prices reflect all available information, rendering consistent market-beating strategies challenging.

Financial Bubbles and Market Behavior

  • Speculative bubbles appear when asset prices exceed intrinsic values due to over-expectation, often followed by a collapse.

  • Bubbles can persist due to investor irrationality and delayed recognition of a bubble's nature.

Personal Finance Lessons

  1. Harness the power of compound interest.

  2. Avoid individual stock picking; focus on broad market investments.

  3. Diversify portfolios to reduce risk exposure.

  4. Remember that past performances do not guarantee future results.

  5. Minimize investment fees for better returns.

  6. Invest in low-cost index funds to adhere to strategies benefiting most investors.
