Inflation Expectations

Inflation expectations are beliefs held by households, firms and workers about the future rate of increase in the general price level. They affect present wage bargains, price-setting, saving and spending, so expected future inflation can influence current inflation even before actual costs rise. Inflation persistence arises when these expectations keep inflation elevated after the initial shock has weakened.

Formation of expectations

Expectations may be influenced by past inflation, current price movements, announced policy and confidence in the central bank. Their effect depends especially on whether they remain anchored around the monetary policy objective.

• When people extrapolate recent inflation into the future, past inflation can create inertia in subsequent wage and price decisions.
• Forward-looking households and firms also consider likely demand, costs and the credibility of future monetary policy.

Price and wage-setting channel

Many prices and wages are fixed for some period rather than continuously adjusted. When higher inflation is expected, forward-looking decisions incorporate the anticipated loss of purchasing power.

• Workers may demand higher nominal wages, and firms may pass the resulting expected labour costs into current prices.
• Firms resetting prices may choose a higher price today because that price must remain viable while costs and competitors' prices are expected to rise.
• Such behaviour can make expectations partly self-fulfilling, creating a wage-price feedback process.

Spending and interest-rate channel

Expected inflation can change the timing of expenditure. Using the approximate Fisher relation, the expected real interest rate equals the nominal interest rate minus expected inflation.

• If nominal interest rates do not rise proportionately, higher expected inflation lowers the expected real interest rate, encouraging borrowing and present consumption or investment.
• Households and firms may advance purchases to avoid anticipated price increases, raising current aggregate demand and the general price level.
• People may become less willing to hold money balances whose purchasing power is expected to fall, increasing expenditure on goods or assets.

Expectations and inflation persistence

A temporary supply or price shock becomes more persistent when it raises expected inflation. Expectations are then incorporated into contracts, wage claims and price revisions, allowing inflation to continue even after the original shock fades. Repeated adjustment can generate second-round effects and reinforce the expectation of continuing inflation.

• Anchored expectations mean that temporary price shocks do not materially alter beliefs about medium-term inflation, limiting their transmission into wages and prices.
• A credible monetary policy framework can prevent temporary inflation from becoming embedded in contracts and price-setting.
• If expectations become unanchored, disinflation may require stronger demand restraint because wage and price decisions continue to embody high expected inflation.
• The effect is not automatic or uniform because demand conditions, labour-market bargaining and policy credibility influence whether expected inflation passes into actual prices.
• Expectations are therefore both a channel of inflation persistence and an important part of monetary policy transmission.
