Chapter 22 - Notes
22.1 - The Bank of Canada
What the Bank of Canada Does
- Canada's central bank β determines monetary policy (setting interest rates to influence economic conditions)
- Created by Parliament in 1934, opened in 1935
- Goal from the Bank of Canada Act: "promote the economic and financial welfare of Canada" by calming fluctuations in production, trade, prices, and employment
- Since 1991, primary focus has been low and stable inflation
- The Bank can't change inflation, output, or unemployment directly β it uses interest rates as its tool to nudge spending up or down
The Bank's Balancing Act
- Too-high interest rate β economy produces below potential β unemployment rises
- Too-low interest rate β output exceeds potential β sparks inflation
- Goal: keep output close to potential output, which achieves stable inflation
Central Bank Independence
- The Bank operates with significant independence from the government β free from short-term political pressures
- Why independence matters: politicians might overheat the economy for short-term gain (boost output before an election), which causes long-run inflation with no lasting output benefit
- Research shows: more central bank independence β lower inflation on average
Government Oversight (Independence β Zero Accountability)
- Board of Directors chosen by the government
- Governor and deputy governor ultimately approved by the Finance Minister
- Bank must publish annual reports, governor appears before Parliament's Finance Committee
- Transparency: everything published openly so anyone can evaluate decisions
- If they disagree: the Finance Minister can issue an official "directive" that the governor must follow β but this has NEVER been used
- The Coyne Affair (1961): Governor Coyne resigned over a dispute with the government about interest rates β led to changes in the Bank of Canada Act allowing the directive power
Monetary Policy in Five Steps
Step 1: Economic Projections (~2.5 weeks before decision)
- Economists run computer models of the economy (C, I, G, NX, commodity prices, US economy, international developments)
- Project inflation, unemployment, GDP growth
Step 2: Major Briefing (~1.5 weeks before)
- Updated data: business outlook survey, bank loan officer survey, financial market data from around the world
- Ground-level intelligence: housing market activity, auto loans, stock markets, bond yields, foreign inflation
Step 3: Policy Recommendations (Thursday before decision)
- Economists and Governing Council discuss final recommendations
- Key tool: the real interest rate (opportunity cost of spending)
- Raise r β spend less β lower output β lower inflation
- Lower r β spend more β higher output β higher employment
- Ongoing process β each meeting builds on previous decisions (was the last rate change enough? too much?)
- Everyone voices a recommendation except the Governing Council members
Step 4: Making the Decision (weekend deliberation)
- Governing Council meets alone, discusses, works through disagreements
- Sleep on it over the weekend β meet again Tuesday for final decision
Step 5: Communication (Wednesday 10 AM)
- Press release, website posting, social media
- Wording is extremely carefully chosen β even small word changes can move markets
- 4 times a year: governor gives live statement and takes media questions
- Governor makes speeches around the country; appears at Parliament's Finance Committee twice a year
- Communication is strategic: the Bank is trying to shape expectations β if people believe inflation will be stable, it's more likely to actually be stable (self-fulfilling, from Chapter 19)
8 monetary policy decisions per year
22.2 - The Bankβs Policy Goals and Decision-Making Framework
The Bank's Mandate: 2% Inflation Target
- Bank formally targets 1% to 3% inflation range with 2% as the midpoint
- Since 2021, the Bank also aims for maximum sustainable employment β but only as long as inflation stays within the 1-3% range
- Inflation remains the primary target; employment is secondary
- By announcing the target publicly, the Bank tries to create a virtuous cycle: if people believe inflation will be 2%, they set prices accordingly, and inflation actually stays at 2% (self-fulfilling from Chapter 19)
Why Target Inflation Instead of Unemployment?
- Inflation is primarily determined by monetary policy β easy to target directly
- Unemployment is affected by frictional/structural factors (minimum wage, unions, efficiency wages) that have nothing to do with monetary policy
- Inflation and unemployment are interdependent β keeping inflation at target also keeps unemployment near its lowest sustainable level
- Unemployment too high β excess capacity β inflation falls below target
- Unemployment too low β capacity constraints β inflation rises above target
- So targeting inflation effectively targets unemployment too β no long-run trade-off
Why NOT Target 0% Inflation? (Four Reasons)
1. Inflation greases the wheels of the labour market
- Employers hate cutting nominal wages (workers resent it)
- With 2% inflation, employers can cut REAL wages by simply not giving a raise β workers don't notice as much
- At 0% inflation, real wage cuts require actual nominal wage cuts β employers avoid them β lay off more workers during recessions instead
2. The Bank can lower real interest rates more when inflation is above zero
- Zero lower bound: the Bank can't set nominal interest rates below ~0% (people would just hold cash)
- Real interest rate = nominal rate β inflation
- If inflation = 2% and nominal rate = 0% β real rate = β2% (stimulative)
- If inflation = 0% and nominal rate = 0% β real rate = 0% (can't go lower)
- Higher inflation target gives more room to cut real rates during recessions
3. A 0% target risks deflation
- Bank sometimes undershoots its target β if target is 0%, undershooting means negative inflation (deflation)
- Deflation is dangerous: falling prices β people delay spending β less demand β prices fall more β vicious cycle
- Deflation also raises the real interest rate (nominal rate minus negative inflation = higher real rate) β further depresses spending
4. Measured inflation may be overstated
- CPI biases from Chapter 12 (quality improvements, new products, substitution bias)
- 0% measured inflation might actually mean ~β1% actual inflation (mild deflation)
How the Bank Chooses the Interest Rate β Four Factors
Factor 1: Start with the neutral real interest rate
- Neutral real interest rate: the real rate when the economy is at potential β neither overheating nor underperforming
- Used to be thought of as ~2%, but may now be well below 2% due to secular stagnation (from Chapter 14)
- Setting r above neutral β output below potential; setting r below neutral β output above potential
Factor 2: The Bank targets the nominal rate to influence the real rate
- Bank controls the overnight rate (nominal rate banks charge each other for overnight loans)
- Nominal rate = real rate + inflation β Bank adds inflation to its desired real rate to get the nominal rate it sets
Factor 3: Compare inflation with the target
- Inflation > 2% target β set real rate ABOVE neutral to cool spending and reduce inflationary pressure
- Inflation < 2% target β set real rate BELOW neutral to stimulate spending and boost inflation
- Bank also looks at inflation FORECASTS to get ahead of problems
Factor 4: Look at the output gap
- Positive output gap β economy overheating β set r above neutral to cool it
- Negative output gap β unemployment too high β set r below neutral to stimulate
- Bank also looks at output gap FORECASTS
The Policy Rule-of-Thumb (Taylor Rule)
Real interest rate = Neutral real rate + (1/2 Γ inflation gap) + output gap
Overnight rate - Inflation = Neutral real rate + (1/2 Γ inflation gap) + output gap
Where:
- Inflation gap = actual inflation β 2% target
- Output gap = (actual output β potential output) / potential output
Then: Nominal overnight rate = Real interest rate + Inflation rate
Example: neutral real rate = 1%, inflation = 1.5%, output gap = +0.5%
- Real rate = 1% + (1/2 Γ (1.5% β 2%)) + (1 Γ 0.5%) = 1% + (β0.25%) + 0.5% = 1.25%
- Nominal rate = 1.25% + 1.5% = 2.75%
Key Points About the Rule:
- The Bank responds half a percentage point for each percentage point of inflation gap
- The Bank responds 1 percentage point for each percentage point of output gap
- The rule is a good predictor of actual Bank decisions but the Bank doesn't follow it mechanically
- Decisions are systematic (reliable pattern) but not automatic (judgment still matters)
- Also called the Taylor Rule after the economist who described it
Rules vs Discretion Debate
- Rules: remove temptation to overheat economy, make policy predictable
- Discretion: allows Bank to get ahead of problems and respond to unusual situations (e.g., 2007 rate cuts before the recession, zero lower bound concerns, financial instability)
- In practice: Bank starts with what the rule suggests, then uses judgment to adjust
22.3 - How the Bank Sets Interest Rates
The Overnight Market
- Banks lend out most of the money you deposit (that's how they make money)
- But they need to keep some cash on hand (reserves) to make payments (e.g., when you write a cheque to your landlord)
- Some days banks are short on cash β need to borrow overnight from other banks
- Some days banks have excess cash β willing to lend overnight
- The overnight rate is the interest rate on these overnight interbank loans
- The Bank of Canada runs this market on a computer platform called Lynx
Four Tools the Bank Uses to Hit Its Target Overnight Rate
Tool 1: Standing offers to lend and borrow
- Bank of Canada offers to accept deposits from banks at the deposit rate β sets the FLOOR (why lend to another bank for less when you can always deposit at the Bank of Canada?)
- Bank of Canada offers to lend to banks at the bank rate β sets the CEILING (why borrow from another bank for more when you can borrow from the Bank of Canada?)
- The range between the deposit rate (floor) and bank rate (ceiling) = the operating band
- The Bank controls this band β just adjust the deposit rate and bank rate to move the whole band up or down
Tool 2: Injecting or withdrawing funds
- The Bank of Canada is the banker to the federal government β tax receipts and government paycheques flow through its accounts daily
- To nudge the overnight rate UP: put less of the government's funds in the overnight market β less supply β rate rises
- To nudge the overnight rate DOWN: leave extra government funds in the overnight market β more supply β rate falls
Tool 3: Repos and reverse repos
- Repo (repurchase agreement): Bank buys a bond from a financial institution, agrees to sell it back next day at a slightly higher price β effectively a short-term loan β injects cash into the market β pushes overnight rate DOWN
- Reverse repo: Bank sells a bond, agrees to buy it back next day β withdraws cash from the market β pushes overnight rate UP
Tool 4: Open market operations (buying and selling government bonds)
- Bank buys bonds β pays cash to banks β banks have more reserves β less need to borrow, more ability to lend β overnight rate goes DOWN
- Bank sells bonds β banks pay cash β less reserves β more need to borrow, less ability to lend β overnight rate goes UP
- This is the traditional central banking tool, but the Bank of Canada doesn't typically use it for regular policy anymore
- Quantitative easing is a special version of this used in unconventional circumstances (covered later)
How the Overnight Rate Affects the Rest of the Economy
Step 1: Overnight rate β other interest rates
- When overnight rate changes, banks adjust rates on credit cards, mortgages, business loans, student loans, savings accounts, auto loans
- Variable rates (credit cards, some student loans) move almost immediately with the overnight rate
- Longer-term fixed rates also adjust because a long-term loan is like a series of short-term loans β banks price it based on expected future short-term rates
- How much long-term rates move depends on how long the Bank is expected to keep the new rate
Step 2: Interest rates β spending decisions
- Lower rates β lower opportunity cost of spending β more consumption and investment
- Lower rates β government pays less interest on debt β potentially more room for government purchases
- The IS curve logic from Chapter 18
Step 3: Interest rates β exchange rate β net exports
- Lower Canadian interest rates β Canada less attractive for foreign investors β less demand for C$ β Canadian dollar depreciates
- Cheaper C$ β Canadian exports cheaper for foreigners β exports rise
- Cheaper C$ β imports more expensive for Canadians β imports fall
- Net exports rise
- The reverse happens when rates rise: C$ appreciates β net exports fall
Full chain: Bank changes overnight rate β other rates adjust β C, I, G, NX all change β aggregate expenditure changes β output changes β inflation changes
Practical Warning
- When the Bank cuts rates, it seems like a good time to borrow β but the Bank cuts rates because the economy is weakening
- You should factor in the risk of losing your job before taking on new debt
- Young people are most vulnerable to unemployment during downturns
22.4 - Unconventional Monetary Policy
The Problem: What Happens When Interest Rates Hit Zero?
- The Bank's main tool is the overnight rate, but it can't go below ~0% (the zero lower bound)
- If the economy still needs stimulus after rates hit zero, the Bank needs other tools
- Goal of unconventional tools: push longer-term interest rates down even when short-term rates are already at zero
Two Unconventional Tools
1. Forward Guidance
- The Bank promises to keep rates low for a long time in order to push down longer-term interest rates today
- Logic: long-term rates are based on expected future short-term rates β if the Bank commits to low short-term rates for years, long-term rates fall
- Example: Governor Macklem in July 2020: "interest rates are very low and they're going to be there for a long time"
- Lower long-term rates β more mortgages, car loans, business investment β more spending
- Only works if people believe the Bank will follow through β credibility is essential
2. Quantitative Easing (QE)
- The Bank buys large quantities of longer-term government bonds to push down long-term interest rates
- In 2020-2021, Bank of Canada bought ~$350 billion in government bonds (asset holdings quadrupled)
- How it works: Bank buys long-term bonds from investors β increases the supply of long-term loans β long-term interest rates fall
- Similar to open market operations but targets long-term rates instead of the overnight rate
- Also signals commitment to keeping rates low (reinforces forward guidance)
- Result: historically low mortgage rates, cheaper long-term business borrowing
Lender of Last Resort
What it is: the Bank of Canada stands ready to lend to financial institutions that need cash immediately but can't get loans elsewhere
- Uses the Emergency Lending Assistance program at the bank rate (higher than overnight rate β only used in emergencies)
- Purpose: prevent bank runs and financial panics
Why it matters:
- Bank runs are contagious (Chapter 15) β one bank failing makes depositors at other banks panic
- During the Great Depression, the US central bank chose NOT to bail out banks β 5,000+ banks failed β deepened the depression
- During 2007-2009, central banks learned from this and acted aggressively β provided massive loans to prevent panic from spreading
- In 2007-2009, the problem extended beyond regular banks to shadow banks (like Lehman Brothers) β central banks expanded their reach to these institutions too
The "Too Big to Fail" Problem:
- Large financial institutions know the central bank will bail them out because their failure would cause widespread chaos
- This creates moral hazard β incentive to take on extra risk (if bets pay off they profit, if they don't the central bank rescues them)
- Bailouts may prevent the current crisis but make future crises more likely
- Solution: regulation β require banks to maintain sounder financial positions so they're less likely to need bailouts
The Bailout Trade-off:
- Using public money to save private companies is controversial β benefits shareholders of failing companies
- But also prevents broader financial chaos that would hurt everyone
- In the 2008 crisis, the US central bank was eventually fully repaid with interest β but there were real risks involved
Questions
- In an effort to maintain inflation at its targeted level the Bank of Canada designs its policies, in the short run, to
Keep real GDP close to potential output - Suppose that the inflation rate is at 5%, but the Bank of Canada does not implement contractionary monetary policy. Which of the following is the most likely explanation?
The Bank of Canada knows that there is a lag in the effects of monetary policy and expects inflation to fall before monetary policy would have an effect. - Starting in long-run equilibrium, which of the following scenarios would be most likely to cause the Bank of Canada to implement expansionary monetary policy?
