What Is Stagflation and Why Does It Matter? A Canadian Investor's Explainer

Highlights

• Stagflation describes simultaneous high inflation and stagnant economic growth with elevated unemployment.

• The 1970s remain the most prominent historical example of sustained stagflation in major economies.

• Defensive sectors, real assets, and inflation-protected securities have historically shown relative resilience.

• Bank of Canada monetary policy and federal fiscal response shape Canadian stagflation outcomes.

Stagflation is one of the most challenging macroeconomic environments for economies and investors, combining the difficult features of recession and inflation. The term emerged in the 1970s to describe the unusual combination of stagnant growth, rising unemployment, and persistent inflation that challenged conventional macroeconomic frameworks.

For Canadian investors, understanding stagflation, its historical drivers, and the portfolio considerations relevant to navigating it can support more informed long-term decision-making.

This explainer covers what stagflation is, the historical context from the 1970s, policy challenges, asset class behaviour during stagflationary periods, and portfolio considerations for Canadian investors. The content is informational and does not constitute trading recommendations.

Defining Stagflation

Stagflation describes an economic environment combining three difficult conditions:

• High or rising inflation

• Stagnant or contracting economic growth

• Elevated or rising unemployment

Each condition is challenging on its own, but the combination creates a particular policy dilemma. Raising interest rates to fight inflation can weaken growth further, while cutting rates to support growth can worsen inflation.

Before the 1970s, many macroeconomic frameworks assumed an inverse relationship between inflation and unemployment. The simultaneous appearance of high inflation and high unemployment challenged that assumption and reshaped modern economic policy thinking.

Historical Context: The 1970s

The 1970s remain the most studied stagflation episode. Several factors contributed to the period, including oil shocks, the breakdown of the Bretton Woods fixed exchange rate system, wage-price spirals, and monetary policy that was initially slow to respond to persistent inflation.

Canada also experienced elevated inflation and weaker growth during this period. The Bank of Canada eventually adopted more restrictive monetary policy to bring inflation under control.

The adjustment helped restore price stability, but it also contributed to a difficult economic environment in the early 1980s. The lessons from this period continue to influence central bank approaches to inflation today.

Drivers of Stagflation

Several factors can contribute to stagflationary conditions.

Supply shocks are among the most important. A sharp increase in energy, food, or other essential input costs can raise prices across the economy while reducing business profitability and consumer purchasing power.

Other drivers may include:

• Productivity slowdowns

• Wage-price spirals

• Unanchored inflation expectations

• Currency weakness

• Large fiscal deficits

• Weak business investment

Each stagflation episode has a different mix of causes. The specific drivers matter because they influence the likely policy response and the effect on asset classes.

Monetary Policy Challenges

Stagflation creates difficult choices for central banks.

If the Bank of Canada raises interest rates to control inflation, borrowing costs rise and economic activity may weaken further. If rates are reduced to support growth, inflation may remain elevated or become more persistent.

Historical experience suggests that maintaining inflation credibility is critical. Central banks generally prefer to prevent inflation expectations from becoming unanchored, even if that requires near-term economic weakness.

Modern Bank of Canada communications place significant emphasis on inflation expectations and the credibility of the inflation target.

Equity Performance During Stagflation

Equities can face pressure during stagflation because weak growth affects earnings while higher inflation and interest rates compress valuations.

During the 1970s, major equity indices delivered challenging real returns over extended periods.

However, performance varied across sectors. Certain areas showed relative resilience, including:

• Energy

• Materials

• Consumer staples

• Utilities

• Healthcare

• Gold-related equities

Canadian energy and materials exposure can be represented through companies such as Canadian Natural Resources Ltd (TSX:CNQ), Suncor Energy Inc. (TSX:SU), Barrick Gold Corporation (TSX:ABX), and Agnico Eagle Mines Ltd (TSX:AEM).

Defensive Canadian companies including Loblaw Companies Ltd (TSX:L), Metro Inc. (TSX:MRU), Fortis Inc. (TSX:FTS), and Emera Inc. (TSX:EMA) may also attract attention during periods of economic uncertainty.

Fixed Income During Stagflation

Traditional fixed-rate bonds often struggle during stagflation.

Rising interest rates can reduce bond prices, while inflation erodes the real value of fixed coupon payments. Long-duration government bonds may be especially vulnerable.

Fixed income areas that may offer relatively better resilience include:

• Short-duration bonds

• Floating-rate notes

• Inflation-linked securities

• Cash-like instruments

Canadian fixed income ETFs such as iShares Core Canadian Universe Bond Index ETF (TSX:XBB), BMO Aggregate Bond Index ETF (TSX:ZAG), and Vanguard Canadian Short-Term Bond Index ETF (TSX:VSB) may behave differently depending on duration, credit exposure, and interest rate conditions.

Real Assets and Commodities

Real assets have historically played an important role during inflationary environments.

Commodities, energy, gold, and certain real estate assets may respond positively when inflation is driven by supply constraints or currency weakness.

Gold has often been viewed as a hedge during inflationary or uncertain periods, although its performance is not consistent across every macroeconomic cycle.

Canadian investors may access real asset exposure through commodity-related equities, gold producers, REITs, infrastructure companies, or ETFs.

Examples include Barrick Gold Corporation (TSX:ABX), Agnico Eagle Mines Ltd (TSX:AEM), Enbridge Inc. (TSX:ENB), and Brookfield Infrastructure Partners LP (TSX:BIP.UN).

Defensive Sector Considerations

Defensive sectors with pricing power and stable demand have historically shown relative resilience during difficult macroeconomic periods.

These may include:

• Consumer staples

• Utilities

• Telecommunications

• Healthcare

• Infrastructure

Canadian examples include Loblaw Companies Ltd (TSX:L), Metro Inc. (TSX:MRU), Fortis Inc. (TSX:FTS), Telus Corporation (TSX:T), and BCE Inc. (TSX:BCE).

The trade-off is that defensive sectors may underperform during strong economic expansions when investors favour higher-growth or more cyclical sectors.

Portfolio Construction for Stagflation Resilience

Building stagflation resilience generally involves diversification rather than relying on a single asset class.

Portfolio considerations may include:

• Diversifying across equities, fixed income, real assets, and cash

• Reducing excessive long-duration bond exposure

• Including companies with pricing power

• Maintaining exposure to real assets and commodities

• Avoiding excessive leverage

• Keeping liquidity available for flexibility

For Canadian investors, account placement across TFSAs, RRSPs, FHSAs, RESPs, and non-registered accounts can also affect after-tax outcomes.

Periodic portfolio reviews can help ensure allocations remain aligned with changing economic conditions and personal financial goals.

Historical Stagflation Episodes and Lessons

The 1970s stagflation episode remains the key historical reference point for Canada and other developed economies. Oil shocks, currency regime changes, inflation expectations, and slow policy responses all contributed to the difficult environment.

Canada later adopted inflation targeting in 1991, creating a more formal framework for maintaining price stability. The 2% inflation target has helped anchor expectations across subsequent decades.

The 2022-2023 inflation episode raised concerns about stagflation in market commentary, although the outcome differed from the 1970s in several respects. Stronger central bank credibility and faster policy response helped shape a different path.

Bank of Canada Inflation Target and Policy Response

The Bank of Canada operates under a flexible inflation-targeting framework, with a 2% target at the midpoint of a 1% to 3% control range.

Policy response depends on:

• Inflation persistence

• Labour market conditions

• Inflation expectations

• Economic growth

• Financial stability

• Global conditions

During periods of high inflation, the Bank of Canada may tighten monetary policy even if growth is weakening. During disinflationary periods, policy may gradually shift toward easing once inflation appears to be returning sustainably toward target.
