A rise in energy prices is often described as an inflation story. It is also a growth story, and the two effects can arrive at the same time.
From fuel costs to household budgets
When oil and gas become more expensive, the first effects show up in transport, heating and electricity. The next stage is less direct: businesses face higher costs for moving and producing goods, while households have less money left for other purchases. If firms respond by postponing investment or hiring, a price shock can weaken demand as well as raise prices. That creates a difficult problem for central banks. Higher interest rates cannot produce more oil or reopen a shipping route. They can slow borrowing and spending. Policymakers must judge whether the price increase is temporary or likely to spread into wages, services and expectations.
Canada shows the two-sided risk
On September 21, Bank of Canada Governor Tiff Macklem warned that newly announced U.S. tariffs could cut Canadian fourth-quarter growth to below 1% if they remain in place. He also described an inflation risk: Canada’s annual inflation rate was 3%, already above the Bank’s 2% target, and sustained high oil prices could add pressure. The same economy can therefore face weaker trade and investment alongside higher energy costs. Australia offers another part of the picture. On September 22, Reserve Bank Governor Michele Bullock said upside risks to inflation may be materialising as energy prices remain high and domestic demand stays strong. Core inflation was 3.6%, above the RBA’s 2%–3% target range, while the cash rate stood at 4.35%. The Bank’s next policy meeting is scheduled for September 29; the warning itself was not a decision to raise rates.
What to watch next
The key question is whether a temporary cost increase becomes persistent inflation. Evidence that matters includes prices beyond energy, wage-setting, household spending, business investment and hiring. If these remain contained, a central bank may have room to avoid tightening into a slowdown. If broader prices and expectations rise, waiting too long can make inflation harder to control. The lesson is not that every energy shock leads to recession or a rate increase. It is that policymakers must watch the shock’s second round: how it changes prices, incomes and decisions across the rest of the economy.
