6.3: Anticipated and Unanticipated Inflation

Inflation can be easier to manage when it is expected. People adjust their decisions based on what they think will happen to prices. Businesses may raise prices gradually, and workers may ask for wage increases to keep up with the cost of living. These small changes help keep things balanced, even as money loses value over time.

When inflation is not expected, it causes problems. Prices rise faster than people planned for, and past agreements may no longer work well. One side of a deal may end up worse off, while the other may gain without meaning to. This makes financial planning harder and can lead to losses.

For example, a local transport company signs a yearly contract with a factory to deliver goods. They agree on a fixed monthly rate, expecting small increases in fuel prices. At first, the costs and payments match closely. But months later, fuel prices rise sharply due to supply problems. The company now spends much more on fuel, but the factory still pays the same rate. The transport company starts losing money because it didn’t expect such a jump in costs.

This is what happens with unanticipated inflation. It affects people who cannot quickly change their prices or incomes. Small businesses, fixed-wage workers, and long-term contracts are most at risk. Even if the overall economy grows, sudden inflation can create winners and losers in everyday transactions. That is why keeping inflation stable and predictable helps people make better decisions and protect their income.

Inflation can be either anticipated, meaning it is expected and planned for, or unanticipated, meaning it deviates significantly from expectations, that is, it rises or falls faster than expected and disrupts agreements.

At the start of a year, Ana, a grocery supplier, signs a one-year contract with Ray, a store manager. They expect inflation to rise about three percent over the year.

They agree on quarterly price increases of 0.75 percent. This is the anticipated inflation rise both sides plan for.

The first half of the year ran smoothly. Ana’s costs rose gradually, and Ray adjusted payments as agreed.

By midyear, a drought hits a negative supply shock. Food prices surge. Inflation jumped nearly ten percent in six months, much faster than expected. Ana’s costs increase sharply, but her payments follow the original schedule.

By June, payments had risen only 1.5 percent, but expenses were significantly higher. Because the contract was fixed, Ana’s profits shrank. This is unanticipated inflation, when prices rise or fall faster than planned, disrupting financial stability.
