2.3 Inflation & Interest Rates
Key Takeaways Explain This Topic AI
Inflation is a sustained rise in the general price level, measured in Canada by the Consumer Price Index (CPI).
The Bank of Canada's preferred core measures, CPI-trim and CPI-median, filter out extreme price changes.
Demand-pull inflation comes from excess demand; cost-push inflation comes from supply shocks and can coincide with falling output (stagflation).
The real interest rate is approximately the nominal rate minus inflation; unexpected inflation transfers wealth from lenders to borrowers.
Interest rates reflect credit supply and demand, expected inflation, central bank policy, default risk and term to maturity.

Price stability and employment conditions represent the dual pillars of macroeconomic health. In Canada, persistent changes in the price level directly dictate central bank monetary policy, corporate capital expenditure plans, consumer spending behavior, and fixed-income portfolio returns. Understanding the relationship between inflation, nominal and real interest rates, and labour market slack is essential for any financial professional navigating Canadian capital markets.
1. Defining and Measuring Inflation
Inflation is defined as a persistent, widespread increase in the general price level of goods and services across an entire economy over an extended period. When inflation occurs, each unit of currency buys fewer goods and services, diminishing purchasing power.
Deflation: A persistent decline in the general price level across the economy (a negative inflation rate). While intuitively appealing to consumers, deflation is economically toxic: it prompts households and corporations to postpone purchases in anticipation of cheaper future prices, depressing aggregate demand, inducing debt deflation, and triggering deep recessions.
Disinflation: A deceleration in the rate of inflation. For instance, if Canada's annual inflation rate slows from 6.5 % 6.5\% 6.5% to 3.2 % 3.2\% 3.2% , the price level is still rising, but at a more moderate pace.
The Consumer Price Index (CPI)
In Canada, the benchmark indicator of retail consumer inflation is the Consumer Price Index (CPI) , compiled and published monthly by Statistics Canada. The CPI measures the percentage change over time in the cost of purchasing a fixed representative "basket" of several hundred consumer goods and services typically bought by Canadian households. Statistics Canada updates the basket weights regularly to reflect spending patterns.
The basket categories and their approximate weightings reflect Canadian consumer expenditure patterns:
Shelter (~30%): Rented accommodation, owned accommodation costs (mortgage interest costs, replacement costs, property taxes), and utilities.
Transportation (~16%): Vehicle purchases, gasoline, vehicle insurance, public transit.
Food (~16%): Food purchased from stores (groceries) and food purchased from restaurants.
Household Operations & Furnishings (~14%): Communications, furniture, appliances, childcare.
Recreation, Education & Reading (~10%): Travel tours, recreational equipment, tuition fees.
Clothing & Footwear (~4%): Garments, accessories, footwear.
Health & Personal Care (~5%): Dental care, pharmaceuticals, eye care.
Alcoholic Beverages, Tobacco & Recreational Cannabis (~5%): Regulated retail items.
The annual inflation rate is computed as the percentage change in the CPI from the same month in the preceding year:
Inflation Rate = ( CPI t − CPI t − 1 CPI t − 1 ) × 100 \text{Inflation Rate} = \left( \frac{\text{CPI}_{t} - \text{CPI}_{t-1}}{\text{CPI}_{t-1}} \right) \times 100 Inflation Rate = ( CPI t − 1 CPI t − CPI t − 1 ) × 100
Headline CPI vs. Core Inflation
While Headline CPI captures total price movements across the full consumer basket, it is highly sensitive to volatile components such as retail gasoline, fuel oil, and fresh agricultural produce. These items are frequently buffeted by transitory geopolitical conflicts, OPEC supply decisions, or temporary weather anomalies that do not reflect underlying domestic demand.
To conduct forward-looking monetary policy, the Bank of Canada relies on preferred measures of Core Inflation that filter out transitory statistical noise:
CPI-trim: A trimmed-mean measure that removes the 2.5 % 2.5\% 2.5% most extreme price increases and 2.5 % 2.5\% 2.5% most extreme price decreases from the price-change distribution each month, focusing on the central 95 % 95\% 95% of price movements.
CPI-median: The price change corresponding to the 50 th 50\text{th} 50 th percentile of the weighted basket of price movements in a given month. It captures the price change of the item sitting directly in the middle of the distribution.
CPI-common: A statistical factor model that isolates common price variations across all CPI categories to gauge broad underlying trends.
2. Demand-Pull vs. Cost-Push Inflation
Economists categorize inflation into two distinct causal mechanisms: demand-pull and cost-push.
Feature Demand-Pull Inflation Cost-Push Inflation
Root Cause Excessive aggregate demand outstripping aggregate supply ("too much money chasing too few goods"). Exogenous supply-side shocks that abruptly increase per-unit production costs.
Macro Setting Operates during mature expansions when the economy faces a positive (inflationary) output gap. Can occur in any phase, including during recessions or stagnant economic conditions.
Primary Drivers Low policy interest rates stimulating credit; Heavy government fiscal deficit spending; Surging foreign export demand; High consumer and business confidence. Global crude oil price spikes; Raw material and component shortages; Supply chain blockages; Aggressive wage increases exceeding productivity gains.
Output Impact Real GDP initially expands above potential before rising costs constrain growth. Real GDP contracts while prices surge, creating the risk of stagflation .
Policy Remedy Restrictive monetary policy (central bank interest rate hikes) to cool domestic aggregate demand. Highly challenging: hiking rates crushes already-weak output, while cutting rates worsens price inflation.
3. Nominal vs. Real Interest Rates: The Fisher Effect
Interest rates represent the price of credit. In fixed-income securities and banking, investors and borrowers must continually distinguish between nominal and real yields.
Nominal Interest Rate ( i i i ): The observed, stated interest rate on a debt contract or bank deposit (e.g., a 5.00 % 5.00\% 5.00% coupon on a corporate bond).
Real Interest Rate ( r r r ): The nominal rate adjusted for the erosion of purchasing power caused by inflation. It represents the true growth in physical goods and services an investor can command.
The Fisher Equation
Named after economist Irving Fisher, the relationship between interest rates and inflation is defined as:
i ≈ r + π ⟺ r ≈ i − π i \approx r + \pi \quad \Longleftrightarrow \quad r \approx i - \pi i ≈ r + π ⟺ r ≈ i − π
Where:
- i i i = Nominal interest rate
- r r r = Real interest rate
- π \pi π = Expected or realized inflation rate
For mathematically precise compounding calculations across larger rates, the exact relationship is formulated as:
( 1 + i ) = ( 1 + r ) ( 1 + π ) ⟺ r = ( 1 + i 1 + π ) − 1 (1 + i) = (1 + r)(1 + \pi) \quad \Longleftrightarrow \quad r = \left( \frac{1 + i}{1 + \pi} \right) - 1 ( 1 + i ) = ( 1 + r ) ( 1 + π ) ⟺ r = ( 1 + π 1 + i ) − 1
Worked Example: Bond Real Return Calculation
An institutional investor purchases a 5-year Government of Canada benchmark bond offering a nominal annual yield of 4.60 % 4.60\% 4.60% . Over the holding period, Canadian CPI inflation averages 2.80 % 2.80\% 2.80% annually.
Approximation: r ≈ 4.60 % − 2.80 % = 1.80 % r \approx 4.60\% - 2.80\% = 1.80\% r ≈ 4.60% − 2.80% = 1.80%
Exact Formulation: r = ( 1 + 0.0460 1 + 0.0280 ) − 1 = ( 1.0460 1.0280 ) − 1 = 1.01751 − 1 = 1.751 % r = \left( \frac{1 + 0.0460}{1 + 0.0280} \right) - 1 = \left( \frac{1.0460}{1.0280} \right) - 1 = 1.01751 - 1 = 1.751\% r = ( 1 + 0.0280 1 + 0.0460 ) − 1 = ( 1.0280 1.0460 ) − 1 = 1.01751 − 1 = 1.751%
The Economic Cost of Unexpected Inflation
When actual inflation diverges from anticipated inflation, significant unintended wealth transfers occur:
Creditors to Debtors: Lenders (bondholders, depositors) are repaid in depreciated currency that purchases fewer physical goods than originally projected. Conversely, borrowers (homeowners with fixed-rate mortgages, corporate debt issuers, governments) repay their debt obligations with cheaper dollars.
Tax Bracket Creep: If income tax brackets and exemption thresholds are not fully indexed to inflation, nominal wage gains push workers into higher marginal tax brackets even though their real purchasing power has not improved.
Capital Investment Distortion: High and volatile inflation introduces uncertainty into corporate hurdle rates, discouraging long-term capital investments in productive plants and equipment.
How Interest Rates Are Determined
An interest rate is the price of credit, and it reflects several forces at once:
Supply and demand for credit. Strong borrowing demand from businesses, households and governments pushes rates up; abundant savings push them down.
Expected inflation. Lenders demand compensation for the loss of purchasing power, which is why nominal rates rise when inflation expectations rise.
Central bank policy. The Bank of Canada's policy rate anchors very short-term rates.
Default risk. Riskier borrowers pay a credit spread over the risk-free rate.
Term to maturity. Longer loans usually pay a term premium.
Interest rates matter to the whole economy. Higher rates raise the cost of borrowing for mortgages and business investment, increase the reward for saving, tend to strengthen the Canadian dollar, and lower the present value of future cash flows, which weighs on bond and stock prices.
