For most Americans, the experience of inflation hasn’t been a steady climb or a sudden jump, but rather a confusing blur of contradictions. One week, the price of gasoline drops at the pump, providing a momentary sense of relief; the next, a monthly rent increase or a higher insurance premium wipes out those gains. This disjointed reality makes it difficult to notify if the economy is actually cooling or if we are simply drifting into a new, more expensive baseline.
To craft sense of these movements, economists often distinguish between the volatile shocks that hit the headlines and the structural pressures that simmer beneath the surface. Think of it as the difference between salt and pepper. The “salt” is the baseline—the persistent, structural inflation that seasons everything in the economy. The “pepper” is the sudden, sharp spice—the volatile price swings that create noise but often fade over time. Understanding inflation trends requires separating these two forces to see whether the Federal Reserve is fighting a temporary fire or a permanent climate shift.
The distinction is more than academic; it dictates whether the central bank raises interest rates, holds them steady, or begins the long-awaited process of cutting them. When the “pepper” hits—such as a sudden spike in oil prices due to geopolitical tension—the Federal Reserve typically looks past it, knowing that energy markets eventually correct. However, when the “salt” begins to thicken—seen in rising wages and stubborn housing costs—the Fed worries that inflation has become “sticky,” potentially embedding itself into the DNA of the economy.
The Salt: Why Some Prices Never Seem to Fall
The “salt” of inflation consists of the goods and services that change price slowly but stay high once they rise. These are the structural components of the Consumer Price Index (CPI) that the Federal Reserve monitors most closely, often referred to as “core inflation.”
Shelter is the most prominent example of this persistence. Unlike the price of a gallon of milk, which can change daily, rent and mortgages are locked in by contracts. When inflation spikes, it takes months or even years for those higher costs to filter through the data as leases expire and new, higher rates are signed. This creates a lagging effect where inflation appears high even after other prices have stabilized.
Beyond housing, “supercore inflation”—a term used by policymakers to describe services excluding energy and shelter—highlights the role of the labor market. When wages rise across the board, businesses often raise prices to maintain their profit margins. This creates a feedback loop: workers demand higher pay to retain up with the cost of living and businesses raise prices to pay those workers. Once this cycle takes hold, the “salt” becomes permanent, making it incredibly difficult for inflation to return to the Federal Reserve’s 2% target.
The Pepper: Managing the Volatile Shocks
While the salt is about persistence, the “pepper” is about volatility. These are the prices that swing wildly based on weather, war, or sudden supply chain collapses. Energy and food are the primary drivers here.
A drought in the Midwest can send corn and soy prices soaring, or a conflict in the Middle East can cause a sudden jump in Brent Crude prices. These events feel visceral to the consumer because they affect daily necessities. However, from a policy perspective, these are often treated as “transitory.” The logic is that a spike in gas prices actually acts as a hidden tax on consumers, leaving them with less money to spend on other things, which eventually slows down the rest of the economy and helps lower overall inflation.
The danger arises when “pepper” becomes “salt.” If a temporary energy shock lasts long enough, businesses may stop treating it as a fluke and start raising their baseline prices to compensate. This is the tipping point where a temporary shock transforms into structural inflation.
| Feature | The “Salt” (Structural) | The “Pepper” (Volatile) |
|---|---|---|
| Examples | Rent, Health Care, Insurance, Wages | Gasoline, Eggs, Fresh Produce, Airfare |
| Movement | Slow to rise, highly slow to fall | Rapid spikes and sudden drops |
| Fed Reaction | Triggers interest rate hikes | Often ignored as “noise” |
| Duration | Long-term/Persistent | Short-term/Transitory |
The Federal Reserve’s Balancing Act
The Federal Reserve is currently engaged in a high-stakes game of discernment. If they react too aggressively to the “pepper”—raising rates because gas prices spiked—they risk choking off economic growth and triggering a recession. Conversely, if they ignore the “salt” for too long, they risk letting inflation become a permanent fixture of the American economy, similar to the stagflation of the 1970s.

This is why the Fed focuses so heavily on the Personal Consumption Expenditures (PCE) price index. By stripping out the most volatile food and energy components, they attempt to see the “salty” core of the economy. They are looking for evidence that the demand for services is cooling and that the labor market is returning to a sustainable equilibrium.
For the average person, this means the “vibes” of the economy often clash with the data. A consumer may feel that inflation is raging because their grocery bill is high (pepper), while the Fed may argue that inflation is cooling because the rate of rent growth is slowing (salt). Both are technically correct, but they are looking at different parts of the spice rack.
Who is most affected by this divide?
- Fixed-income earners: Retirees are more vulnerable to “salt” inflation, as their income doesn’t always adjust to the permanent rise in healthcare and housing costs.
- Low-income households: These families spend a larger percentage of their income on “pepper” items (food and fuel), meaning volatile shocks hit them harder and more frequently.
- Homebuyers: The persistence of “salt” in the housing market keeps mortgage rates higher for longer, as the Fed maintains high rates to combat structural inflation.

The next critical checkpoint for these trends will be the upcoming release of the monthly CPI report and the subsequent Federal Open Market Committee (FOMC) meeting, where policymakers will decide if the “salt” has finally diminished enough to justify a reduction in interest rates.
